4420 Engine Removal

[Shawn23]

Looking for input and helpful points on removing an engine from a 4420 combine. I have the mechanics manual for maintenance from JD on this machine but it seems a little vogue in some of the steps.

Also, I'm looking for input on how to test the oil cooler for a JD329 engine. I was told a seal may be blown out and is why I am getting coolant into the oil.

The head was checked and so was the head gasket and both were good.

Let me know your thoughts.

Drain the radiator pull the radiator
out disconnect the air cleaner and the
exhaust pipe. Unhook the throttle cabl
and the engine shutoff to the
injection pump. Take the bolts out
around the bell housing. This is off
the top of my head did a 6600 years
ago

4400 had to go under the seat to get the bell housing bolts. Seat went out the back window or close.

Check for sleeve cavitation.They were prone for that.

Remove tension from drive belts on outboard end of tailstock to keep it from twisting when seperated from engine. I am not sure
if rad had to come out. Very doubtful that oil cooler is the issue, most likely sleeves/o-rings
