Yokomo YOKBDS2W P3 O-Ring Collar (Thin) – Shim/Collar RC accessory  [YOKBDS2W]

P3 O‑Ring Collar (Thin) overview

This Yokomo YOKBDS2W P3 O‑Ring Collar (Thin) is an RC-scale shim/collar accessory intended to help position and retain O‑rings and spacers in small assembly locations. Its thin profile makes it suitable where minimal axial build-up is required and where fine adjustment of clearance is needed during model setup.

Use cases are focused on component-level tuning: holding O‑rings in place on shafts, adding controlled spacing between mating parts, and assisting in repeatable assembly during maintenance. The part is presented as a simple mechanical collar rather than a multi-function assembly, so its role is to provide consistent axial positioning in compact areas of a model's drivetrain or suspension linkages.

Installation is straightforward: the collar is placed on the shaft or locating post before the O‑ring or spacer that it supports. Because this is a thin-profile collar, it is intended where thicker shims would cause unwanted stack-up. When fitting, verify axial clearance and rotate assemblies by hand to confirm there is no binding. Use common hobby tools to slide the collar into position and secure adjacent components as per your chassis setup practice.

For tuning, this collar is a minor but precise option for managing endplay and ensuring O‑rings remain seated under operational loads. Use it when you need a low-profile solution to maintain sealing or spacing without altering gear mesh or suspension geometry significantly.
