Just bought an 1855, didn't get it running yet, PO said they replaced the original engine with a 20 horse linimar/onan performer and it ran hot and lost power ever since. The engine supposedly only has very low hours on it. My question is did anyone else have a hot running problem with one of these? Thanks. Bill.

Some of the later model Onan engines had fixed flywheel screens & would clog up with debris easily, then overheat FAST! People would just cut an access hole for the driveshaft through the stationary screen.

We re-powered our 1855 B48M with a P220 and never had a heat issue.
Did the mice move in and cause a restriction, could the shrouding not be installed correctly?
That is a shame that that P220 was trashed. If I remember right our conversion cost us around $1700.00 in the early 80s. Cam nose broke on the B48 and have no reason why. Just driving along and Bang we stopped right there.

There's a good chance that a valve seat came loose from the heat. Not hard to repair. If the seat came loose, then you'd be running off one cylinder, which would drop your power by at least 60%.

I don't know if the engine is trashed, he said they stopped using it because they couldnt resolve the heat issue. Parked it and bought something else.

If it does have a stationary flywheel screen, most likely a rotating one that bolts to the flywheel could be used....that is if the flywheel has holes for it, or bosses that could be drilled & tapped. Take a look & see if the screen rotates with the flywheel.

Hope to get into it tomorrow, I have to get the snowblower on the kubota G5200 before the Buffalo winter moves in. Then I can get the 1855 in the garage. Here's to hoping I can get the engine running and the hydraulics work good. I want to build a loader for something don't know if it will be the kubota or the massey.

Just a thought but here is a leak down tester that can be built from everyday parts either in the shop or off the shelf very helpful in diagnosing the problem
Building and Using a Cylinder Leakdown Tester
it help me determine if it was leaking at the rings or the valves, if its the rings it pull the engine time.
  • ducky and Texas Deere and Horse have said thanks

How about to lean a fuel mixture, will that cause heating problems?

Good chance that all the overheating problem is just plugged up cooling fins from mice or what ever.
Maybe you could remove the shrouds and see if there is anything foreign in there restricting the airflow, It's not going to cost any money to do this.
