Yokomo YOKBDS2W P3 O-Ring Collar (Thin) - Shim and Collar Accessory  [YOKBDS2W]

Role of the P3 Thin Collar in Small Assemblies

The Yokomo YOKBDS2W P3 O-Ring Collar (Thin) serves as a compact shim and collar accessory to hold O-Rings and minute spacers in place within confined RC assembly areas. Its reduced thickness allows precise clearance control where space is limited.

It is commonly used to secure O-Rings on shafts, set exact spacing between components, and facilitate repeatable rebuilds during maintenance. The collar performs a single mechanical role: providing reliable axial positioning in tight drivetrain or linkage spots without adding unnecessary height.

Fitting involves sliding the collar onto the shaft or locating post before the O-Ring or spacer it supports. As a thin-profile item, it avoids the extra stack-up associated with thicker shims. Always check rotation and axial clearance after installation to ensure there is no binding, and use usual hobby tools for placement and securing adjacent parts.

When adjusting setups, this collar is a subtle means of controlling endplay and keeping O-Rings seated under load. Use it when you require a neat, low-profile way to preserve seals and spacing without materially changing suspension or gear alignment.
