Ok guys.
Dad and my brother are building a power unit to run an auger on the farm via 540 PTO. They aquired an engine from a 750 Massey combine(aka Perkins 354). They had an adapter made to mate it to a truck transmission through a direct coupling. Tonight they get it up and running to report that the output of the trans is running counterclockwise facing the shaft from the rear!!!??? My brother verified smoke from the exhaust, and oil pressure, so its not running backwards on accident.

Did the Perkins 354 run counter clockwise in the combines??

I told them to go back out in the morning and start it again and verify rotation of the engine, and the output of the trans. Initially my brother thought the trans was the culprit, but I cannot imagine that, as there is a 1:1 gear ratio and it runs CCW. In reverse the output runs CW.

Does anybody know if the tractor 354 has the same block as the combine 354?

CCW at the rear is cw from the front. Perkins blocks are the same from tractor to combine but there are a lot of differences in the rest of the motor. I swapped a 510 combine motor into an 1100 Massey tractor and had a lot of mixing and matching of parts to do. Earlier engines had a splined snout on the crankshaft for a front drive hydraulic pump. Later versions had a trans driven pump and a smooth snout so no way to drive pump, I found this out after I pulled a motor out of a 550 Massey combine.

 

Oliver 1850 had the perkins 354, also the white 105,110 and I beleive the white 135 (not positive but pretty sure). Lots of differences between the Dot series (dot 1, 2, 3 ect..) and also the heads are different on turbo (white 135) and non turbo models.
Good luck,

the white 2-85 has a non-turbo 354, the 105 or 110 has a turbo'ed 354. The 135 white has a HUGE hercules(478 ci) motor. Sorry sometimes I confuse even myself.\

I got a 372 perkins turboed out of a 750 massey combine .

Ok, I talked with dad. He says its running right, everything is turning the way it is supposed to. Sorry for the false warning about wrong rotation on the engine. Shoulda kept my mouth shut until I went and saw the setup.

I think the problem now is the rotation is right, but PTO 540 rpm runs clockwise looking at the back of a tractor, and currently we are now counterclockwise. This is something nobody thought about when this project started.

Now I *guess* dad is looking for a 1:1 gear box that changes rotation of the shaft.

Thanks for reading.

Thats an easy one. Use a rear axle off of any truck with an open differential. Lock down the driveshaft input. Feed the output shaft into one side of the axle. The other end will rotate the opposite direction at a 1:1 ratio.

 

That was a thought, but I remember what my auto mechanics teacher told me. When you do enough one legged burnouts, the thrust washers will wear out and then the diff will fail. Effectively this is what will happen, cause the ring and pinion won't be moving, and the spyder/side gears will do all the moving. They are not designed to do that day in and day out, and most times running 80-125 hp through it. The diff is designed to allow for little differnces in speed of one tire compared to its mate. Am I right?

This power unit will be used to run an auger during harvest. If the drive train fails then the whole operation stops to fix it. As much trouble as it is to keep something like a combine going, the auger to the grain bin and power unit needs to be bullet proof.

Thanks very much for posting.
