This Yokomo Y2-508A kit provides the small service parts used to service ball-type differentials on RC-scale models. The kit groups the T-nut, adjustment screw, coil spring and O-ring supplied for routine maintenance or replacement during differential rebuilds.
Technically focused, the kit is intended for use when disassembling and reassembling a ball differential to restore adjustment range and preload control; it supports basic tuning steps such as replacing worn adjustment springs or sealing O-rings to retain grease.
Use this kit when servicing a ball differential to replace worn adjustment components and to preserve differential adjustment feel; keep spare kits on hand if you rebuild diffs frequently.
