Yokomo YOKZCRA3620 8pc 3x6x2mm Red Collar Spacers  [YOKZCRA3620]

Installation and Fit Guide for 3x6x2mm Collars

This Yokomo YOKZCRA3620 collar set is a basic spacer solution for R/C models that use 3x6x2mm collars. The set contains 8 pcs in red, suitable where a narrow collar or shim is required between hubs, bearings, or rotating shafts to manage lateral placement or clearances on drivetrains and wheel assemblies.

Fitting is straightforward: place the collar over the shaft or into the bore that corresponds to 3x6x2mm, then check axial placement and running clearance with the model under load. The part functions as an accessory component for correcting small misalignments, adjusting wheel offset, or swapping out worn collars during routine checks.

Practical tips: ensure the shaft diameter and mating bore match a 3x6x2mm collar, fit the collar, and secure using the original retaining method such as a set screw, clip, or hub fastener. Make iterative spacing changes and verify drivetrain alignment and wheel runout after each adjustment to prevent binding or excessive play.
