Yokomo YOKY2-500GM Differential Maintenance Set for YD-2 and YZ-2  [YOKY2-500GM]

Inspection and rebuild notes for YD-2/YZ-2 differentials

This maintenance kit is intended for servicing the gear differential assembly used on Yokomo YD-2 and YZ-2 touring car chassis. It covers inspection of internal gears and components, removal of old lubricant and debris, and the replacement of worn internals when necessary to restore correct function.

A usual service routine is to withdraw the differential from the chassis, scrutinise gears and bearings for wear or damage, clean all contact faces and passages, and reassemble with the appropriate differential oil or grease chosen for your set up. Proper reassembly ensures accurate gear mesh and helps prevent accelerated wear in RC operation.

From a handling perspective, maintained differential internals contribute to steady traction and predictable corner behaviour on carpet and asphalt, helping drivers fine tune balance and consistency. Carrying out checks after running sessions helps identify small faults before they become performance-limiting issues.
