Subject: Military surplus 3500 generator engine in a D21


West Central Iowa
I have spoken for a rebuilt military surplus 3500 engine with the intentions of putting it in a D21 (with series ll conversion) that I have had sitting here way too long waiting for me to rebuild an engine to put in it. I am aware that the timing cover, the front engine plate and hydraulic pump drive will need to be swapped from the D21 engine to the new engine. I don't know if the rebuild engine has a crankshaft driven oil pump or the earlier cam driven oil pump, but will the oil pan on a 3500 engine with the crank driven oil pump clear the D21 front axle without modification? This rebuilt engine also has a right angle tachometer drive coming out of the tach drive location on the block, so it either has the cam driven oil pump or some sort of stub tachometer drive.

I am also aware that I will need to swap a lot of the engine accessories, most of the fuel system, along with the rear engine plate and flywheel.

I would like to to look as close to "stock" as possible so I plan on using the D21 parts wherever possible.

Any other possible surprises that I may not be thinking of?

Thanks!
