Does the fly wheel housing and pump rack have oil in them? If so, where do you check it and where do you fill it?
Check oil at transmission dip stick pump rack do you mean injection pump it is lubricated by engine
Flywheel housing contains the torque converter which is part of the transmission system, so the level is checked using the transmission dipstick. By the sounds of your question you badly need an operation/maintenance manual. They can be downloaded for $50. Post a Serial Number for a link to the correct one for your particular machine.
