Shim 3.1 x 5 x 0.05mm - Yokomo YOKZCS305  [YOKZCS305]

Micro shim for tuning and mesh adjustment

This shim is sized 3.1 x 5 x 0.05mm as noted in the product name and functions as a precision spacer for small clearance corrections in model builds. It is ideal when tiny, consistent thickness steps are needed to tweak bearing preload, improve gear mesh alignment, or trim shaft endplay without reworking parts.

To install, place the shim where required on the shaft or mating surface prior to assembling the next part, confirm overall stack thickness with a caliper or feeler gauge if possible, then tighten the fasteners carefully to avoid overcompressing the shim. You can stack shims to reach intermediate values; always keep surfaces free of grit to avoid false readings.

As a standard accessory, the shim fits a variety of R/C locations including axle points, gearbox stacks, servo horn interfaces, and bearing endplay spots. Treat it as a delicate component during handling and storage to prevent bending or loss.
