No. The crankshaft is manufactured to KE21SP dimensions and is not a direct fit on other engine models without modification.

What bearings or seals should I use during installation?

Inspect the crank journals and install bearings and seals that match the KE21SP specification or OEM equivalents. Replace any worn bearings when fitting the new crank.

Any break-in advice after fitting this crankshaft?

Run a staged break-in with moderate throttle and short sessions, monitor temperature and vibration, and recheck clearances before full-power use.
