Geardiff Bushing 4.6x6.5x4 for Pan Cars

Arrowmax AM-931015 is a precision 4.6x6.5x4 bushing intended for pan car gear differential stacks in 1/12 and 1/10 scale. Its function is to locate the diff shaft and reduce sideways play so gears maintain consistent engagement during use and setup.

Check the bore and shaft sizes for a snug fit prior to assembly. Drive the bushing into the housing squarely and inspect shaft rotation for any binding. Apply a light lubricant to contact areas to ease break-in and prevent premature wear while avoiding excess that could alter diff response.

Replacing worn or loose bushings is a straightforward tuning step to recover consistent backlash and repeatability between runs. Different bushing fits will change the feel of gear mesh and freeplay, so always recheck gear engagement and diff preload after changes.
