3.1 x 5 x 0.3mm Precision Shim for R/C Shafts - Yokomo YOKZCS330  [YOKZCS330]

3.1 x 5 x 0.3mm precision spacer

This Yokomo shim is a compact R/C accessory made to deliver controlled spacing where tight clearance matters. The 3.1 x 5 x 0.3mm figures specify inner diameter, outer diameter, and thickness, making the part suited to close tolerance adjustments on shafts and pins found in drivetrains and suspension linkages.

Fit this shim to remove endplay, correct small mesh misalignments, or stack with other shims for incremental changes. Because it is intended for model assemblies, installers normally place the shim between rotating components or between a bearing and its housing to obtain the required running clearance without altering primary parts.

To install, slide the shim onto the shaft or locating pin until it sits flat, ensure there is no binding, then cycle the assembly through its full range of motion. For tuning, add or remove one 0.3mm shim at a time and retest until the desired axial play or feel is achieved.
