Bolens 1886-01 Engine Swap Help

Question for everyone. I am taking out my K482s as it failed (35 hrs after rebuild) and I have the opportunity to get s NEW (old stock) Kohler K582 23 hp engine. My question is.....the shafts, or at least one of them look slightly different on the new one.....can this be easily resolved like taking shafts off old engine or something else? I want to make sure this engine will work for me before I buy it which I was told it was.

Compare the diameters, the 582 will likely be larger. NOS? Boy, that engine has been sitting around a long time!

I know I’m very surprised there are any NOS of those around at all. This guy has 4 of them. They were stored inside with caps over exhaust and carb. If it is slightly larger or different size is it a huge deal to swap from old motor or something?

Re: Bolens 1886-01 Engine Swap Help

The front drive shaft that runs the three belt pulley assembly is a bolt-on piece that fits on the flywheel end...that should be a direct swap. The other end is the crankshaft itself. The typical issue is that these Bolens engines (at least on the K532 and K582 units....not sure if the 482 had it) have a hole through the output end of the crankshaft for pinning the hydro driveshaft to the engine. That is a particular engine specification. If the replacement engine isn't a Bolens spec, it won't have that hole.

That said, my repower didn't have it either, I just used set screws to hold the shaft tight, and that's worked fine.
