Yokomo YOKBDS2W P3 O-Ring Collar (Thin) for Precise Spacing - RC Shim Accessory  [YOKBDS2W]

P3 Thin Collar: Purpose and Use

The Yokomo YOKBDS2W P3 O-Ring Collar (Thin) is an accessory intended to help locate and hold O-Rings and tiny spacers in compact RC assemblies. Its thin form factor is ideal when you want accurate spacing without adding significant axial height.

Common applications include holding O-Rings on small shafts, establishing precise clearances between mating parts, and aiding in consistent reassembly during maintenance cycles. The item functions as a straightforward collar rather than a complex multi-part device, supplying repeatable axial position in tight drivetrain or link areas.

To fit, slide the collar onto the shaft or post prior to placing the O-Ring or spacer it supports. Being thin-profile, it prevents excessive stack-up that thicker shims might cause. After placement, manually rotate connected parts to ensure there is no binding and verify required clearance. Typical hobby tools are sufficient for installation and adjustment.

When tuning, use this collar as a subtle control for endplay and to keep O-Rings correctly seated under operational loads. It is a discreet way to preserve sealing and spacing without altering suspension geometry or gear engagement noticeably.
