TRF421 Gear Diff Set, RC differential parts set

The TRF421 Gear Diff Set brings the core parts of a gear differential into one RC maintenance and assembly pack, with a 37T differential case, bevel gears, cross pieces and metal outdrive cups arranged for a focused driveline rebuild. The included oil, gasket plate and sealing parts support the internal mechanism where the gears rotate inside the closed housing. Inside the set are 2 black housing halves, 2 large silver bevel gears, 4 smaller bevel gears, 2 white cross-shaped internal parts, 2 metal shafts or pins, 2 small straight pins, 2 ring bearings, blue O-rings, washers, shims, spacer discs, clips and screws. These parts work together through a clear mechanical sequence: the bevel gears sit inside the case on the cross pieces, the outdrive cups connect at each side, and the housing closes around the assembly with the gasket and screws. The bearings support the rotating sections, while shims and spacers help position the moving parts within the differential body. This set suits workshop use, scheduled maintenance and replacement of worn differential internals on a TRF421 build. On the bench, the laid-out parts make it easy to sort the assembly stages, check each sealing and spacing component, and rebuild the differential with the required hardware close at hand.
