Crankshaft washer for GT22 engines

This drive washer is intended as a precision axial spacer for GT22 crankshafts, controlling endplay and maintaining alignment between the crank and the engine case plus drive components.

Practical fitting notes: clean the mating faces, slide the washer onto the crank seating face, and check endplay by rotating the assembly. Minor changes in washer location can influence timing cover clearance and spur/pinion mesh on GT22-based models.

Fit carefully and confirm the washer seats evenly around the crank journal to avoid tilt or misalignment. This item is a precision engine part for hobby nitro RC use and not general-purpose hardware.
