My Magnum 8 Electric Start broke the Rod Cap off and I was looking to replace the 8M-ES with another Kohler engine. The CH395 Looks close, but I was wondering what kind of problems I was going to get into trying to Engine Swap this old Kohler (retired) to the new 9.5 hp version. Has anyone done and engine swap and if so with what engine?

Welcome aboard! Another Georgia boy! Swapping out engines all depends on the mounting points and linkages. Wiring isn't usually a big issue. What equipment are you wanting to swap engine on?

I was looking at completely replacing the 8M-ES with a CH395-ES. So it would be a complete swap. I would put back the clutch and drive pullies. I just needed to know if anyone has swaped out a 8M-electric Start for another engine and how did that go?

It appears no one has an answer for me, so I will have to go with out help.

Any of the K series engines will work as well.

I'll bet most of the folks on here would rebuild the stock engine if possible, or replace with similar. A rebuild would be way cheaper than a new engine and take less time than figuring out all of the issues with squeezing something different in; mounting points, cutting the hood?, rewiring, possibly different cables. You haven't said which model of Wheel Horse you have. Does it have safety lock outs?

I have a 308-8 Wheel Horse with a M8S that has been rebuilt once "professionally" (think it would have been better if I had done it myself, but I was not going to be home for several months and the wife thought she wanted to mow the grass.) Cost me more in parts that the new Kohler. Got a guy now that says he will give me all the engine numbers that will direct replace my 8M. Thanks guys for all you help, but I think I'm closing in on the solution. My Wheel Horse is a 1986 36" rear discharge and I plan to keep using it for another 30 years, or death - which ever comes first. If you want, when I get it going again, I'll take pics and send in the required changes.

Thanks for your response. It sounds like you have it worked out. There might be some people on here that might be interested in that replacement list if you care to share.

I don't know what that second number engine is??? Magnum I get, but nothing else? I just bought this same model tractor at show and fella put in a V-twin magnum. Had to use the engine mount plate, not direct to frame and drilled new holes in that plate. These twins have a small foot print compared to kohlers and others. I'm going to use engine in diff tractor, and might try to put one back in the Horse. Thinking of a big Briggs, I have several and have never seen one on a horse. Maybe it is too big for hood, don't know yet. Mine is the 8spd trans, like that rear, but rest is manual lift and other not so featured things. Must have been the economy line for them?

GL, the CH395 is the Command Pro OHV 9.5 hp slant cylinder engine.
