Allis 185 engine swap ??????

Picked up a nice 185 with bad crank. Found a really low hr 301 out of a combine. Swapping things over a found the combine engine has a shallow oil pan vrs a deep pan on original engine.Wondering what the reason for this was and if ill be find just droping new engine in without swapping pans. Tia

Yes im in the works of changing front plate now along with a number of other small changes but was curious about the gear driven pump. Would prefer not to change all that if isnt required. Thanks

You cannot use an engine with the crankshaft driven oil pump/deep pan on a tractor that doesn't already have the same thing. There is interference with the front axle. Your shallow pan and oil pump will fit on the newer engine. Not really more oil pressure (spec is 35 to 55 psi hot wide open throttle) but more volume 16 GPM versus 12ish GPM) for extra oil filters, piston cooling and turbochargers. If you are using a turbo'd engine for the swap, you must remove the spring and slug in the rear crossover oil galley if you are removing the oil cooler on the right side of the engine.  If you remove the oil cooler and fail to remove the sporing and blocking slug in that crossover passageway, you will have the main and rod bearings destroyed in a few minutes of run time from NO OIL PRESSURE to them!!

My tractor originally had a deep pan and crank driven oil pump. Your saying i will not be able to use a engine with a shallow pan then?

My combine engine im using does not have the gear driven pump. But the engine that was in tractor does.

Meaning, your combine engine is OLDER than your tractor engine. Once the crankshaft driven pump was released, ALL those 2000 series engines eventually got the wider crank gear, even tho some still used the camshaft driven style pump. Old blocks don't even have a place for the front pump to attach to.

So in this case he will need to just keep the combine pan on it? Tractor pan will require a different matching pickup. 

2900 engines with the oil cooler have a thigher placement of the engine fan - have to mover the shroud - it will work.  Also just cut the front pivot and move it and the rear axle pivot up the distance of the hole location in the rear support -weld a plate to the rear pivot  and drill extra holes. Takes about 4 hours of cutting and welding to lower the axle.  - done about 8 of these swaps now.
