Kyosho Motor Cycle Alloy Oval Washer for Gear Box by GPM KM010  [KM010]

Alloy oval washer for gearbox

This is a pair of alloy oval washers intended for RC-scale Kyosho motorcycle gear box assemblies, sold as 2 pcs. The washers act as spacers and locating shims inside the gearbox area where oval mounting or shaft clearances require a non-circular washer profile.

Made for hobby use only, the washers provide a lightweight aluminum option to replace thin stamped washers when a more consistent thickness and stiffer seating are needed. They are useful when tuning gear mesh, reducing lateral play, or aligning the spur and pinion in compact motorcycle gearboxes.

Installation is straightforward: clean the mating surfaces, place the oval washer to match the keyed or offset hole orientation, and reassemble the gearbox hardware ensuring the washer sits flush against the mating face. Check mesh and endplay after final assembly and make minor adjustments as required.

The part is an RC-scale spare intended for Kyosho motorcycle gearbox configurations referenced in the product title, do not use for any full-size vehicle applications.
