Products Application
Starter Mechanism Overhaul
Direct replacement when the original washer in the starter assembly is worn or damaged. The washer sits on the starter post between the rope rotor and the spring clip . If the starter is slipping, a worn washer is often the culprit. Replacing it resolves the issue without needing a full starter replacement .
Starter Rebuild Service
When rebuilding the recoil starter, the washer is a key component. Available as part of comprehensive rebuild kits, these service sets provide all components needed to restore the starter to full working order, including the washer, spring, pawl, rope rotor, and starter grip .
Preventative Maintenance
Replacing starter washers proactively prevents starter failure. As noted by experienced mechanics, worn washers develop grooves that can cause starter dogs to stick and slip . Routine replacement during chainsaw servicing avoids starter issues in the field.
