Crankshaft And Flywheel Assembly

Crankshaft and flywheel assembly for the engine bottom end, also listed under the older E9489 number.

PN · 70-9489

This is the crankshaft and flywheel assembly, listed in the parts books under CRANKSHAFT AND CONNECTING RODS. It's the rotating heart of the engine's bottom end, carrying the flywheel and providing the journals the connecting rods ride on. When a parts book lists this as a complete assembly rather than a bare crank, it usually means you're buying the crank and flywheel already mated together as one unit, ready to go into the cases.

On these engines the crank and flywheel work together to smooth out the power pulses from the pistons and keep the motor turning evenly at idle and low revs. This one shows up in the catalog under both its current number and the older E9489 form, so if you're working from an earlier parts book you may see it listed that way.

Our record on this one shows it appearing across several catalog entries spanning into the mid '70s, but we don't have specific model-year fitment details beyond that. Give us a call with your engine number or model and we'll confirm before you order, since crank and flywheel assemblies aren't universal across every variant of the range.
