I just acquired a 560 D while buying a new house in Montana. I decided to try to fire it up today . It has 6000 hours on it. I do not know much of the history other than it was bought new in 1959 and has sat around for at least 5 years. I own an old diesel truck so I have general diesel knowledge. I cleaned the tank and filled with fresh diesel.. I installed a new group 31 battery. The engine cranked slow and I found out that the solenoid ontop of the starter is worn out. Next I figured I would pull start it . While pulling I noticed that the fan on the engine is not turning, and it doesn t seem like the engine is cranking. I cannot hear or see the engine sucking or blowing air. The transmission seems to shift fine but I think something is out of adjustment or broken in the clutch or transmission area. Like the engine isn t engaging the transmission. I had the TA all the way forward. Maybe a broken crank ? Any ideas or things to check would be helpful. Thanks !
