Yokomo YOKIB644C - Main gear shaft collar for DIB (Blue)  [YOKIB644C]

Main gear shaft collar for DIB

This Yokomo YOKIB644C item is a dedicated shaft collar designed for use with DIB main gear assemblies on RC models. It serves as a locating and retention component that sits on the main gear shaft to control axial movement and maintain consistent mesh between the main gear and pinion.

Fitment is straightforward: position the collar on the shaft to contact the gear face or spacer as required by your chassis layout, then secure according to your vehicle’s service instructions to remove unwanted endplay. The blue finish provides quick visual identification when preparing spares or doing chassis setup work.

In tuning and setup, this collar helps stabilise gearbox behaviour by limiting shaft shift under load, which can reduce inconsistent gear engagement and improve drivetrain predictability. Use it as part of routine checks when adjusting spur and pinion alignment or diagnosing gear noise and play.
