PROCEDURE
1 Operate the turning gear to turn the crankshaft while you do an inspection of all teeth.
NOTE: On new engines during the running-in period, you must do a visual check of
the gear wheels after approximately one and two operation hours. You must
do the same checks on used engines that have new gear wheels installed.
NOTE: To do checks of the clearances and tooth marks, you must tighten the tie rods
and elastic studs of the main bearings.
2 Set to on the service pump.
3 Make sure that oil flows freely from all nozzles.
4 Set to off the service pump.
5 Make sure that all screws are correctly locked.
6 After the running-in period, do a check of the drive wheels each three months as given
above. If faults show during this period, repair them.
7 If you hear unusual noises in the area of the gear train, you must find the cause.
Replace defective drive wheels as soon as possible to prevent damage to adjacent drive
wheels.
