We can also ship freight collect collect via the carrier of your choice.

LIMITATION OF WARRANTY: The items in this catalog are designed and manufactured specifically for use in race cars. Woodward Machine Corporation does not warranty or guarantee race car components for the following reasons, among others: (1) The conditions of end use are normally hazardous and unpredictable, and are entirely beyond our control; and (2) The decision as to the suitability of said components for a particular manner of use, or in a particular installation, is made by the user and is likewise beyond our control. Liability of Woodward Machine Corporation is therefore limited to the replacement or repair, at our option, of any of our products that we find, upon our inspection, to be defective in materials or workmanship, specifically excluding items damaged as a result of collision, misuse, or neglect.

RETURNS OF MERCHANDISE: Returned parts may be subject to a charge of up to 20% to defray the cost of inspection, restocking, and repackaging. Returned merchandise must be unused, unmarked and not over 30 days old. We will make adjustment via exchange or credit only. Customer-modified parts, special order parts, damaged or rusted parts, or “basket cases” are not returnable except in connection with repair orders.

SPECIAL ORDER PARTS: In this catalog, certain categories of parts are available in various lengths and sizes to fit different race cars. We offer most of these custom variations at no extra cost. Please note, however, that some parts, if built to unusual or uncommon specifications, can be specialized enough to be otherwise unsalable. Such items require prepayment and are not returnable.

REPAIR SERVICES: We can usually rebuild an old rack and pinion to a f unctionally new condition for less than the cost of a new unit, provided its major components are salvageable. In the case of a wrecked unit, a reasonably careful cleaning and boots-of f inspection before sending it in will of ten reveal the extent of the damage, and may save the customer the trouble and expense of packing and shipping it to the factory. Basic (i.e. non-crash) rebuilds qualify for a flat rate which includes parts and labor. Crash rebuilds usually have to be quoted after inspection. Weld repair of “impact craters” at the ends of the rack housing is usually possible and we do it regularly. Material ground off the bottom from contact with pavement is in a relatively unstressed area and can be ignored unless it has actually gone all the way through. The following items, however, are not repairable: (1) grinding in the juncture of the pinion boss and the mounting pads; (2) grinding into the snubber threads; and (3) grinding into the top of the housing. Please note that if the customer has ground or machined material from these areas of the housing for clearance, it may be structurally weakened and unsafe for reuse. When sending something for repair, always use UPS or FedEx so its progress can be tracked. With UPS, freight insurance is free up to 100.00 value, and costs 60 cents extra for every additional 100.00 of value. Always insure your equipment for what it would cost you to replace it. If UPS should lose your insured package they will settle your claim promptly. IMPORTANT: DO NOT SHIP YOUR PARCEL VIA US POSTAL SERVICE. At present, the US Postal Service does not deliver to street addresses in our area, so it cannot come directly to our plant. It may be rerouted to our PO Box, which adds some delay, or it may be returned to you. We have no way to track incoming Postal Service freight and w ill not even know you sent it until we receive a notice in the mail. Also, experience has shown that if you do send it via US Postal Ser vice, and it gets lost or damaged or simply remains undelivered, you will find it very difficult and time-consuming to obtain compensation. PROPER PACKAGING will ensure that your items arrive here with no more damage than they originally sustained on the race track. Cushion the parts firmly, and protect any protruding shaft ends from puncturing the carton. Do not put heavy objects into a carton loose, or with nothing between them but styrofoam pellets. Servos, cylinders, hoses, and the like should be drained, plugged, and sealed in plastic wrap, or they will soak the carton, possibly causing the label to come off in transit or the parcel to disintegrate. Please put a note inside the carton describing the problem, and include a daytime phone number so that we can call you with an estimated cost.

2009 Engineering Changes Orders: 1-888-STEER-US •


Rack type recognition Beginning in 2008, Woodward racks underwent a comprehensive redesign. Because almost every detail of our racks was re-engineered and improved, almost none of the internal parts are interchangeable between the former types G/H, and the present type GE/HE. The following pages show the individual parts in their old and new versions. While bearing/seal kits and some par ts are still available for the older racks, no old-style parts will be manufactured after existing stock is depleted. To provide maximum service to our customers during this transition period, old racks sent for rebuild will be eligible for upgrade to the new design at a heavy discount. The illustration below points out the readily identifiable external features which distinguish the new HE rack from the old H rack:

Ratio stamped on top of housing Grease tting on near side

Lighter-section r bbed casting 2000 PSI PTFE hose with permanent ends Housing accepts large-bore G150C cylinder Cylinder is closer to rack Rod bracket is shorter

HE

(new)

Servo mounted with six 10-24 bolts

Ratio stamped on bearing cap

H

(old) One grease tting on far side; another underneath

Servo mounted with three 1/4-20 bolts

Please note that improvements and new features are being introduced as time permits. Not all current features or options are shown in the above illustration, but most are. Other Woodward rack types have also been updated or superseded by new designs, and these changes are shown in their respective sections of the catalog.



G100

GE/HE100

GE/HE housing replaces both G and H The former H rack, with its mounting provision for direct mounting of the servo, was distinct from the former type G which had no such provision and could be used only with an inline or remote servo. The new GE/HE rack housing can be used either way. When built as a type GE the servo mounting holes have bolts installed in them to exclude dirt. Except for the bolt hole at the upper left, which goes through to the interior, these bolts can be discarded and the cast boss cut or ground off if desired. However, leaving the mounting provision in place enables a GE rack to be converted to an HE at a later time by adding the servo adapter.

More compact design Computer-des igned material distribution has greatly increased the stiffness and load-carrying ability of the new housing while offering an extra .25 inch of usable rack travel over the previous type G and H housings. The grease fitting has also been relocated for improved access in the car. The pinion area now packs 50% greater ball-bearing capacity into a shorter space and allows the cylinder to be mounted closer to the rack without compromising the alignment of the pinion with the steering shaft.

GE/HE100

H100

GE500 (new)

E313 (old)

E500D (old) Specic-ratio machining A five-axis machining process specifically locates the pinion bore for each ratio. The old design used a large assortment of eccentric bear ing caps to accommodate different pinions, and was limited to a ver y coarse adjustment. The new caps have a very small eccentricity which allows the gear backlash to be set to virtually zero while preserving free conjugate action, and eliminating any need for drag-producing preload.

GE400 (new)

E400D (old)

GE313 (ne w)

All-ball-bearing pinion The new pinions are supported by THREE ball bearings for increased radial load capacity and reduced friction. This feature a dds significantly to the useful life of the rack, since pinion bushing wear and eventual misalignment of the gear teeth is completely eliminated. The stacked pair of ball bearings used to resist thrust loads was proven effective over many years and has been retained in the new design. A new lip seal to exclude dirt and pressure-washer fluid replaces the o-ring formerly used .



GE150B

GE150C

Improved Cylinder The assist cylinder has also undergone a minor change to take advantage of the new housing. Because the type GE/HE housing is more compact lengthwise, it provides approximately 1/4 inch greater usable rack travel when countersteering to the right than was possible with the former type G and H. Installing an older G150B cylinder on a new des ign rack will interfere with rack travel to the left and should have its old design G170 piston rod changed out for a GE170. The GE150B cylinder (or a G150B converted with a new piston rod) can be made backward-compatible with old racks by adding a .25 inch stack of washers between the rod and the bracket. The GE150C large-bore cylinder is standard on the 4.19 and 4.45 racks and optional on slower ratios, but will NOT fit older G and H racks.

G264 (old) GE264 (new)

Installed: G170 piston rod (old)

New Rod Bracket

Old

Moving the cylinder closer to the rack has resulted in a shorter and stiffer rod bracket capable of transferring the full force of the large-bore cylinder at maximum pump pressure without de flection. Its failure threshold has been raised by the addition of a very high tensile (200,000 PSI) bolt manufactured by ARP. This bolt is available with replacement old-style G264 rod bra ckets on special order.

Lightweight Pressure Hose We have replaced the previous 1500 PSI hydraulic hose and reusable ends with PTFE core 2000 PSI hose and permanent ends, for lighter weight and improved flow. All hose end fittings are manufactured by Woodward.

New part numbering system Our part numbers have been expanded to include as many useful details as possible. Virtually any option can be specified using the codes shown above. Certain rack types are available with extra options, such as the GE/HE series which can be provided with a special rackshaft with two right-side tie rod holes for use on chassis with interchangeable mounting positions for the right-side upper and lower control arms. For example, part number GE366CC-1825/1925-955-210 would be an otherwise standard 18.25 rack but with an extra tie rod hole located one inch outboard on the right. Another combined number is used in the GL/HL series, where frequently the rack travel must be limited to less than the standard 6 inches. If, for example, a 25 inch rack is required to have 5 inches’ travel, this is done by installing a 25 inch rackshaft in a housing ordinarily used for a 26 inch rackshaft. The part number for such a rack and pinion might be HLM209X-2500/2600-850-2-215. Certain rack series (notably the GL/HL, MR, MRC and MC) consist largely of custom designs, and can therefore have more possible part numbers than will fit on a catalog page. Although nominally built to order, GL/HL racks are offered in standard length increments and these are shown in all their permutations in the Master Price List. MR, MRC and MC racks, however, are subject to practically infinite dimensional variations and are assigned individual model numbers during the design stage.

Ratios quicker than 3.14 inches per turn, although availa ble on special order, are not shown as standard because they are not generally practical without power assist. The former extra-slow ratios of 1.83 and 1.57 have been discontinued. The housing is machined for later conversion to power steering. Racks with standard or monoball rack ends can be e quipped for power-assisted operation by bolting on a servo, a cylinder, and the appropriate rod bracket. Other parts required are pump, reservoir and hoses. See the Power Steering Components section for details.

Type GE Power Racks (ratios from 2.09 through 3.14 inches per turn) Power steering with inline servo, paved oval track applications With power steering, the physical effort of steering is independent of the gear ratio; therefore, it is usually possible to use much quicker steering than with a plain manual unit. The servo has a splined input and output and can be installed anywhere in the steering column. The servo case does not have to be mounted to the chassis, provid ed at least one end is rigidly coupled into the steering shaft. The High Load Option is recommended for chassis setups using extreme anti-dive/caster gain or quicker steering ratios.

Type HE Power Racks (ratios from 2.09 through 3.14 inches per turn) Power steering with integral servo, paved oval track applications These units have the servo mounted directly to the rack. This arrangement eliminates the extra u-joint and coupler used with an inline servo, and uses shorter hoses. The servo can be rotated for hose clearance. When ordering, specify the ratio and rack length (e.g. HE262CB-1825) and the servo valve and valve torsion bar (e.g. 855-205). The High Load Option is recommended for chassis setups using anti-dive/extreme caster gain or quick steering. Note: Many pavement race cars use a le ft-side block-mounted dry-sump pump which crowds the area of the serv o. In cases of interference, the servo can be easily separated from the rack and mounted inline without any loss of function.

Type GE Power Racks (ratios from 3.14 through 3.92 inches per turn) Power steering with inline servo, dirt oval track applications The servo has a splined input and output and can be installed anywhere in the steering column. The servo case does not have to be mounted to the chassis, provided at least one end is rigidly coupled into the steering shaft. The High Load Option is recommended for chassis setups using extreme anti-dive/caster gain, or where mechanical leverage is lacking due to spindles with short steering arms. The most popular ra tio in this group is the 3.66; the slower ratios were at one time used in late models practically everywhere but are now used mainly for limiteds or on cars running exclusively on larger race tracks. If your steering requirements are unknown, call us for a recommendation.

See the Power Steering Components section for hoses, ttings and adapters, pumps, reservoirs and other high performance accessories.



Type HE Power Racks (ratios from 3.14 through 3.92 inches per turn) Power steering with integral servo, dirt oval track applications Like their paved-track counterparts, hese units have the servo rigidly attached to the rack with six bolts. Note: The crossmembers on some existing dirt late models may interfere with these bolts. While a double-tube crossmember can easily be modified for the necessary clearance and reinforced with a backup gusset, it is generally not practical to do this on a single round tube. In such cases the rack and servo can be separated and installed as an inline setup, which is functionally identical. Some chassis are now being built with a crossmember specifically designed to accept this rack without interference; if you are considering a new car, call us for recommendations. Chassis setups using extreme front anti-dive (caster gain) and/or short steering arms may need the High Load Option.

MONOBALL rack ends and the appropriate rod bracket can be furnished with any power rack on a custom order basis. Because of their 52 degree operating range, monoballs are useful in cases where standard rod ends are reaching their misalignment limit and causing a mechanical bind. Note: The freer action of monoballs may reduce the steering effort enough to need a stiffer torsion bar in the servo.



Type HE Power Racks (ratios 4.19 and 4.45 inches per turn) Super-quick power steering with integral servo, dirt oval track applications The 3.92, 4.19 and 4.45 ratios are equipped standard with the High Load Option. The larger internal porting of the 900 series servo is designed specifically for the unrestricted flow neede d to power the larger-bore cylinder at the higher velocities of these racks. Note: These racks require a constant pump volume of at least 3 GPM (12 liters/min). Also, because steering ratios of four inches per turn and up have a severely reduced mechanical advantage, pumps used with these racks should be equipped with a pressure relief setting of 1450 PSI (100 bars). Use of a Woodward de-aerating reservoir with a -8 return line and the -12 pump intake kit is highly recomended to prevent overheating (see the Power Steering Components section for details of these accessories).

Type GE Power Racks (ratios 4.19 and 4.45 inches per turn) Super-quick power steering with inline servo, dirt oval track applications Functionally identical to the HE Super-Quick rack, the GE Super-quick has a separate servo intended for installion at any convenient point along the steering column. The servo case does not have to be mounted to the chassis, provided at least one end is rigidly coupled into the steering shaft. The High Load Option is standard on the 4.19 and 4.45 ratios. Because steering this quick has a severely reduced mechanical advantage, pumps used with these racks must be capable of supplying at least 3 GPM and should be equipped with a 1450 PSI relief setting. The oversize -12 pump intake kit is also recommended.

Type GL Manual Racks (2.09-3.14 ratios) Longer length manual steering applications Designed to accommodate the longer rack lengths typical of GT race cars, the housing is made to support the rackshaft proportional to its length, with no more overhang than necessary for the required rack travel. Mounting dimensions for all GL/HL racks can be found in the Technical Reference section. The type GL uses the newer internal parts of the GE/HE, such as the all-ball-bearing pinion, and has replaced the former type K. Although they can be supplied on s pecial order, ratios quicker than 3.14 are not listed since these are generally not practical to use without power assist, and the former extra-slow ratios of 1.38 and 1.57 have been discontinued. Manual racks are available in all three tie-rod styles.

For manual steering purposes, monoball rack ends are by far the preferred style. They promote easier steering because they do not impose offset loads. The type GL can be converted for power assisted operation by bolting on either the G150B or G150C cylinder, as well as either the 800 or 900 series servo. Direct servo attachment was not possible with the K series. The two -bolt rack mounting method, besides providing clearance for an integral servo, is much more fabricator-friendly than the former type K with its vertical bulkhead mount. With a GL, chassis bracketry can be as simple as a pair of tabs with 1/2 inch holes.

GL (new) Engineering improvements from type K The four 3/8 holes of the type K are replaced with two 1/2 holes with the pinion angled upward 15 degrees from the mounting plane. Viewed from above, the pinion is angled away from center at 20 degrees instead of 12.



Type GL Power Racks (ratios from 2.09 through 3.14 inches per turn) Power steering with inline servo, road racing and custom car applications As with the manual GL racks, the housing is made to support the rackshaft proportional to its length, with no more overhang than necessary for the required rack travel. Ratios quicker than 3.14 are not commonly used in the applications of these racks and are not listed as standard; howeve r, since power assist removes any mechanical obstacle, ratios up to 4.45 are available on special order. The former extra-slow ratios of 1.38 and 1.57 have been discontinued. The GL is intended to replace the former KC rack with minor refabrication of the mounts on the chassis.

Type HL Power Racks (ratios from 2.09 through 3.14 inches per turn) Power steering with integral servo, road racing and custom car applications These units have the servo mounted directly to the rack. The servo can be rotated for hose clearance. The High Load Option is recommended for heavier cars (above 2400 lb/1100kg) or for special-order quicker ratios. In cases of component interference, the servo can be easily separated from the rack and mounted inline. The HL rack is functionally identical to the GL, but the integral-servo configuration eliminates the extra u-joint and coupler needed with an inline servo.

Type MR Power Racks Power steering with integral cylinder and servo , for road racing and proprietary supercars For installations requiring relatively long pivot centers. Vastly lighter in weight than any production-car power rack, the minimum length possible to build depends on the rack stroke and the pinion location. MR racks can be built as left or right hand, front or rear steer, offset or centered, in two ratios—2.02 and 2.24 inches/rev (51 and 57 mm/re v) and with a maximum stroke of 5.38 inches. In most MR applications the steering arms on the hub carriers are fairly short, and the rack trave l will rarely exceed 4.5 inches. The MR mounts in clamp brackets and can be oriented to any angle. A tapped bolt circle on the end of the servo provides a rigid and convenient third mounting point. In most cases the rack velocity is low enough that an electric power steering pump can be used. Options include mounting provisions for data acquisition equipment and additional weight reduction by gundrilling the rack shaft. Many variations are possible, a few of which are shown at left. To obtain a design proposal and a quote please specify the following details so we can determinewhether one can be manufactured to fit your application: (1) Pivot center distance (2) Total rack travel required L to R (3) Ratio (rack travel per revolution) (4) Pinion location relative to center (5) Front or rear steer (i.e. whether the rack is to be located ahead of or behind the front wheels) Other information about the car can be very helpful in determining the required level of power assist. If the vehicle is an early-stage prototype and its characteristics are unknown, we suggest the prototype rack be ordered with a range of servo valve components to allow substitution during track testing. Please bear in mind that not all dimensional combinations are possible. For example, the MR rack has an integral hydraulic cylinder which obviously cannot occupy the same space as the rack teeth. What is often overlooked is that both of these elements must move the full length of the rack travel without mutual interference. This fact imposes a definite minimum on the length of the rack housing, which dictates a minimum length for the rackshaft, which in turn must protrude from the housing at each end by a distance equal to half the travel. It will be seen that the mounting points on MR racks are located at the extreme ends of the housing tubes so as to obtain the minimum possible rack shaft overhang and the maximum stability. This feature is essential in extracting the maximum efficiency from such an extremely lightweight unit. In cases where a power rack must be made especially short, it is sometimes possible to mount an external cylinder parallel to the rack, as shown at left.



Type MRC Power Racks Power steering with integral cylinder and inline servo , same applications as MR series For type MR applications where severe space conflicts exist in the area of the pinion housing such as in front-engined race cars. MRC racks use the much smaller housing of the MC manual rack. With this setup the servo is mounted independently and is connected to the pinion through an intermediate shaft and/or universal joints. Like the MR, these racks can be made left or right hand, front or rear steer, offset or centered, with a maximum stroke of 5.38 inches. While functionally identical to the integral-servo MR, separating the servo from the pinion removes some dimensional constraints and incidentally enables the use of some additional gear ratios. Although there are no functional limitations on its distance from the rack, it is important not to mount the servo within the driver’s compartment in a way that could directly expose the driver to the radiant heat of operation or to hot fluid. In order to quote an MRC rack we must have the following information: (1) Pivot center distance (2) Total rack travel required L to R (3) Ratio (rack travel per revolution) (4) Pinion location relative to center (5) Front or rear steer (i.e. whether the rack is to be located ahead of or b ehind the front wheels) When considering the MRC design, please bear in mind that not all dimensional combinations are possible. Like the MR, the MRC has an integral hydraulic cylinder which cannot occupy the same space as the rack teeth, and the same “stackup” of dimensions will influence the length of the housing. However, the smaller pinion housing of the MRC rack usually permits offsetting the pinion somewhat farther to one side than is possible with the MR, all other things being equal. Pinions for MC and MRC style racks are available for 2.02 inches (51 mm) per turn, 2.24 (57 mm) per turn, and 3.14 inches (80 mm) per turn.

Type MC Manual Racks Manual steering for lightweight formula cars, dragsters, LSR cars, FSAE projects The MC rack uses the same mounting clamps as the power racks as well as the same clevises. Like the power racks, the mounting points are located a fixed distance from the ends of the housing, which is calculated to result in the minimum possible shaft overhang and the greatest tie-rod stability. Completely modular in design, most MC configurations are available virtually “off the shelf” except for the rackshaft itself which must be custom made according to length and number of teeth required. Like all Woodward racks these units have the .750-20 pinion spline, which provides a substantially more positive engagement than the .562-36 usually found on small steering racks. To achieve equivalent light weight, the pinion is hollow. To determine whether an MC rack can be built to fit your application, please provide the following details: (1) Pivot center distance (2) Total rack travel required L to R (3) Ratio (rack travel per revolution) (4) Pinion location relative to center (5) Front or rear steer (i.e. whether the rack is to be located ahead of or b ehind the front wheels)

All units not requiring machining modications to the housing (e.g. radical offsets) are priced the same. MC .....................................645.00
