R/C Chassis Shim 3.1 x 5 x 0.2mm - Yokomo YOKZCS320  [YOKZCS320]

Fine 3.1 x 5 x 0.2mm shim for gear and bearing adjustments

This RC-scale shim is intended to provide accurate spacing and small tolerance corrections on model car chassis. The dimension 3.1 x 5 x 0.2mm specifies the shim's footprint and thickness for use when balancing axial clearance or adjusting gear mesh.

Use it to reduce axial play on shafts, tweak bearing preload, or refine spur-to-pinion engagement where tiny thickness changes translate into measurable driveline response differences. The shim serves as a thin spacer enabling incremental changes without replacing core parts.

Installation is simple: clean the mating faces, slide the shim into the required interface, then reassemble. After each adjustment, check for free movement and correct mesh, adding or removing shims incrementally until handling and clearance targets are met.
