Serpent 110474 Shim 4x8x0.2  [SER110474]

Precision 4x8x0.2 Shim

This Serpent 110474 shim is an RC-scale 4x8x0.2mm thin washer intended for fine adjustment of gear mesh and component spacing in model car drivetrains. It is a simple, neutral accessory used to correct small axial or lateral play where a precise thickness is required.

Installation is straightforward: place the shim between the mating surfaces that require correction, verify mesh and rotation by hand, and add or remove shims in small increments until the desired clearance and alignment are achieved. Use clean, lint-free surfaces and fine tweezers to handle the thin shim to avoid bending during placement.

In tuning practice the 0.2mm thickness is useful for incremental changes to gear stack height, motor pinion spacing, or bearing preload where a fractional thickness change affects noise, wear, or mesh quality. Treat the shim as a measured adjustment layer rather than a fix for worn parts.
