4x7x0.5 RC shim for Mini Spyder
This Serpent SER110472 shim is an RC-scale thin washer intended for precision spacing on small shafts, hubs, and suspension link interfaces. It matches the 4x7x0.5 designation in the part name, and is presented as a dedicated spare for Mini Spyder Monster truck assemblies where fine clearance control matters.
Functionally, a 0.5mm shim like this is used to remove unwanted play between rotating parts, to set bearing pre-load, or to align gear faces and wheel hubs. Use it where minimal thickness increments are required to fine-tune axle height, wheel runout, or steering geometry without changing other hardware.
Installation tips: install shims cleanly onto the shaft or over the bearing outer as required, stack shims only when needed to reach the target clearance, and verify free rotation and gear mesh after each incremental change. Avoid forcing shims onto rough or damaged surfaces to prevent deformation.
Tuning role: small shims are a low-risk way to adjust handling and driveline behaviour on scale models, letting builders correct small alignment and backlash issues without altering major components. Keep a few sizes on hand during setup and after crashes when small spacing corrections are often required.
Practical for maintenance and setup tasks, this part serves as a simple precision spacer in tight RC assemblies where 0.5mm increments matter.
