Makita 321855-3 Crankshaft Replacement Part

Product Description

The MAKITA 321855-3 is an OEM replacement crankshaft designed for compatible Makita power equipment.

Failure of this part typically results in loss of power transmission or engine seizure. This part is installed by small-engine technicians and experienced service professionals performing internal engine rebuilds on Makita lawn and garden equipment.

This crankshaft is intended for use in Makita lawn and garden power equipment requiring an internal engine rebuild or crankshaft replacement. It is suited for service center environments and field repair scenarios where the original crankshaft has worn, cracked, or failed.
