TCG 2020 K Maintenance schedule
Maintenance Please note that the following maintenance schedule is a standard maintenance schedule.. ule A fixed definition of the maintenance intervals for all applications is not possible due to the various relations between ambient conditions, operating mode and quality of the fuels. A shortening of the given interval may be necessary under critical operating condition s. The normal maintenance plan is then to be adapted . Normally, the local operating conditio ns are already taken into account in the projection phase. Critical operating conditions are for example: -

Talk to your service partner if in doubt.
General This engine is built exclusively for the purpose set out in the scope of supply - defined by the equipment manufacturer (use for the intended purpose). Dependi ng on the purpose, the engine is identified by a performance code or a type of gas code which is embossed on the rating plate. The rating plate is described in detail in chapter 2. The maintenance schedule lists the measures for maintaining the nominal condition and thus operational safety of the engine with the corresponding intervals. When the specified interval or opera ting hours have been reached, or if necessary, the work specified in the maintenance schedule must be carried out. The activities are described on job cards. The job cards are listed in chapter 9. The operating manual contains the job cards up to the maintenance and service schedule E40. The workshop manual lists the job cards up to the maintenance and service schedule E70. z
The intervals specified in the maintenance schedule are maximum values and assume that installation, intended purpose and operating conditions comply with the specifications. It must be ensured that all running materials such as combustion gas, lube oil and coolant are of the prescribed quality.
It must be ensured especially that the gas quality meets the minimum require ments according to TR 0199 - 99 - 3017 to avoid avoid opera operating ting malfu malfunct nctions ions and/o and/orr prematur premature e engine engine wear. wear. z
The maintenance schedule only applies to the engine itself and the parts mounted on the engine. System parts must be serviced according to the times and instructions specified by the manufacturer. The appropriate information can be found in the manufacturer documents supplied.
z
The measures described must be carried out by technically skilled p ersonnel or authorized specialists. The competencies are listed in the maintenance and service schedule table.

Maintenance and service schedules The operating hour-dependent maintenance measures are divided into maintenance and service schedules. All the listed measures are to be carried out carefully according to the maintenance schedule specifically defined for the engine. Please note that maintenance and service schedules may be added or omitted depending on the speed and gas group.

Selection and installation A suitable maintenance schedule is allocated for the engine, depending on the speed and gas group. The maintenance plan consists of several sections: -
Maintenance measures
-
Data on the average service life of wear parts
-
Master copy for proof of execution
Plan in plenty of time when the the maintenance and service schedules are due in accordance with the engine's number of operating hours. Arrange in advance the anticipated date with your service partner. When making the appointment, inform him of any irregularities in the engine. If appropriate, draw up a maintenance contract with your service partner. All due maintenance measures, and any repair measures depending on the agreement, will then be planned and carried out properly by the service partner conformant as set out in the contract. Your local service partner will provide the details.

Definition of tasks in the maintenance schedule Settings Setting torques, dimensions, pressures etc.; extra work may be necessary to renew components.
Draining Draining condensation for example.
Replacing Replacement of components, function blocks and liquids.
Reworking Material acceptance within the permissible tolerances to maintain a nominal condition.
Checks Checks according to criteria in the job card. If all criteria are not satisfied, the cause must be determined and the nominal condition reinstated.
Cleaning Cleaning by hand or machine (automatic), replacement of cleaning components (e.g. air filter) may be necessary.
Visual inspection Visual inspection according to criteria in the job card. If all criteria are not satisfied, the cause must be determined and the nominal condition reinstated.
Overhauling Checking of function blocks; rework or renewal of components.
Maintenance Maintenance according to job card. Checking functions; reworking or renewal of components may be n ecessary.
Changing Changing lube oil for example

TCG 2020 K Maintenance schedule
Gas groups The maintenance intervals also depend on the quality of the combustion gases. The combustion gasses are divided into three gro ups according to their wear properties, for which the different normal maintenance plans are valid, also see Technical Bulletin 0199 99 - 3017. Gas group 1
Natural gas Pit gas Liquefied gas such as propane, LNG (liquefied natural gas) Wellhead gas (petroleum gas)
Gas group 2
Sewage gas Landfill gas Bio-gas
Gas group 3
All gases in which the concentration of every single po llutant gas component doe s not exceed 20% of the permissible limit value (see limit value list). e.g. bio-gas after a desulphurisation treatment
Maintenance interval If using combustion gases with a high pollutant load, the maintenance intervals (TBO/Time Between Overhaul) have to be reduced because of the high level of abrasion. To ensure the required tool life, the composition of the combustion gases must be determined at regular intervals by means of a comprehensive gas analysis. For more information, see Technical Bulletin 0199-99-3017. If necessary the maintenance intervals must be reduced accordingly.
