SRX8GTR Gear Mesh Shim 4x8x0.2 - Serpent 110474  [SER110474]

4x8x0.2mm Precision Shim for Gear Alignment

This Serpent 110474 shim is a 4x8x0.2mm thin washer made for precise adjustments to gear mesh and component spacing in model car drivetrains. Use it where a measured, fractional thickness is needed to remove play or correct alignment without replacing parts.

Fitting is simple: insert the shim between the mating faces that need correction, check mesh and rotation by hand, then add or remove shims in small steps until clearance and alignment meet your target. Work on clean surfaces and use fine tweezers to avoid bending the shim during placement.

In setup and tuning the 0.2mm value is handy for small changes to gear-stack height, motor pinion spacing, or bearing preload; these tiny shifts can affect noise, wear, and mesh quality. Treat the shim as an adjustment layer rather than a remedy for worn components.
