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.
