Yokomo YOKY2-500GM - Gear Differential Maintenance Kit for YD-2/YZ-2  [YOKY2-500GM]

Gear differential maintenance for YD-2/YZ-2

This maintenance kit is designed for servicing the gear differential assembly used on Yokomo YD-2 and YZ-2 scale touring car chassis. It focuses on tasks that keep the internal gear components functioning smoothly in model use, including inspection, cleaning, and replacement of worn internals when needed.

Typical service workflow covers removing the differential from the chassis, inspecting gears and internal parts for wear or damage, cleaning old lubricant and debris from tooth faces, and reassembling with appropriate differential fluid or grease suited to the driver's setup. Careful reassembly maintains gear alignment and prevents premature wear of the drivetrain in RC-scale operation.

From a tuning perspective, properly maintained differential internals affect traction and corner behaviour on carpet or asphalt surfaces, helping drivers dial in predictable power transfer between axles. Regular checks after running sessions help catch wear early and preserve consistent handling characteristics.
