1850 perkins

[bmat]

Does anyone know what the differences are in Perkins 6-354 engines. I have seen several posts that say engines are different. Will a 6-354.4 replace an original 354 in an 1850? In other words if you have all the parts from an original, what will keep engines from interchanging. Combine engines, truck engines, marine?

One thing I WOULD want is the heavier uprate drive injection pump, the early small hub pump drive have exploded, and I've seen the small splined quill drive split lengthwise..

Somebody posted a while back about the oil pump mounting different. One bolted in and one was held by a set screw or something. You have to use the tractor oil pump and plumbing. The manifold bolt pattern might be different too. Some are horizontal, some are diagonal. I'd make sure the crank is the same where the front pulley goes on.

All that said, I put one from a White 8700 combine in my 1850 and everything was the same.

Im far from an expert on the 354, but I know there are different crank snouts, some are splines, our 1850 was, some are keyed, some use a 2 piece rear main, some use a one piece lip seal. Depending on what you need, it can be a challenge to find the right stuff.

I dont have the engine in the tractor yet because Im waiting on parts to rebuild the 3 speed, but I used the original 372/massey oil pump because it was the 6 lobe instead of the 4 lobe. I had to use the 372 pickup too, but that moved the pickup back about an inchmaybe forward I dont remember). The oliver one would have bolted up, but it would have put the tube outside of the oil pan since the pumps wider.
