Yokomo YOKZCRA3620 - 3x6x2mm Collar spacer set, 8pcs Red  [YOKZCRA3620]

3x6x2mm Collar spacer

This Yokomo YOKZCRA3620 collar set provides a simple, scale‑appropriate spacer option for R/C models requiring 3x6x2mm collars. The pack contains 8 pcs in red, sized for situations where a thin collar or shim is needed between hubs, bearings, or rotating shafts to control lateral position or clearances on model drivetrains and wheel assemblies.

Intended use is straightforward: fit the collar onto the shaft or into a bore where the 3x6x2mm dimensions match, then verify axial position and run clearance under load. The part is an accessory-level component for fine tuning wheel offset, correcting small misalignments, or replacing worn collars during maintenance and setup.

Installation notes: confirm the shaft diameter and mating bore accept a 3x6x2mm collar, slide the collar into place, and secure with the original retaining method (set screw, clip or hub fastener). When adjusting spacing, work incrementally and recheck drivetrain alignment and wheel runout after each change.
