Serpent SER110472 4x7x0.5mm precision shim for Mini Spyder SER440001  [SER110472]

Thin 4x7x0.5 spacer for Mini Spyder

This Serpent SER110472 shim is a thin RC washer made for accurate spacing on small shafts, hubs and suspension link interfaces. It matches the 4x7x0.5 size in the part name and is supplied as a spare for Mini Spyder Monster truck assemblies where small clearance adjustments are important.

In practice, a 0.5mm shim like this removes unwanted play between rotating parts, sets bearing preload, and helps align gear faces and wheel hubs. Fit it where small thickness changes are required to tweak axle height, wheel runout, or steering geometry without swapping major parts.

Installation advice: slide the shim onto the shaft or over the bearing outer as needed, stack identical shims only to reach the desired clearance, and check free rotation and gear mesh after each change. Do not force shims onto rough or damaged surfaces to avoid deformation.

Tuning role: tiny shims are a low-risk method to refine handling and driveline behaviour on scale models, allowing builders to correct minor alignment and backlash issues quickly. Keep several sizes available during setup and after impacts when small spacing fixes are often necessary.

Useful for maintenance and fine setup work, this part provides a simple, precise spacer where 0.5mm increments matter.
