Adjusting endplay with a GT22 washer

This drive washer is a thin, precision spacer designed to set axial clearance on GT22 crankshafts, helping maintain alignment between the crank and engine case as well as associated drive parts.

Fitting best practice: inspect mating surfaces, slide the washer into place on the crank seating face, and rotate while measuring endplay. Small changes to washer placement will affect timing cover clearance and spur/pinion mesh on GT22-equipped models, so tune carefully.

Fit the washer with care to ensure even seating around the crankshaft journal and to avoid introducing tilt. It is a precision component intended for hobby nitro RC engines rather than general hardware use.

A tuning-friendly crankshaft spacer for GT22 engines, handy when adjusting endplay, timing cover clearance, and overall drive alignment during setup or service.

How does changing washer position affect engine timing?

Moving the crank axially can change timing cover clearance and related timing components; verify any timing-critical settings after adjustment.

Can washer thickness improve spur and pinion engagement?

Small spacing changes help fine-tune gear mesh; test rotation under load and adjust until optimal engagement is achieved.

Should other components be checked after altering endplay?

Yes. Reinspect bearings, timing cover clearance, and drive gear alignment after any change to washer placement.

Is hand-fitting precise enough for tuning?

For fine tuning use feeler gauges and rotate the crank while measuring; avoid forcing parts and confirm adjustments under rotation.
