Drive Train, Axle & Brakes

Drive train, axle, and brake parts transfer power to the wheels or tracks and help control machine movement. The system includes axles, bearings, chains, sprockets, brake components, gearboxes, and related hardware used between the hydraulic drive and the machine's ground-contact components.

Identification should account for the exact skid steer or compact track loader model, serial or PIN, installed side and position, shaft or spline details, bearing dimensions, chain and sprocket geometry, gearbox markings, and brake configuration. Visual similarity alone does not establish interchangeability.

Separate a rotating support part from a power-transmission or braking part before searching. Note which side of the machine is involved, how the component is retained, the mating shaft or hub, lubricant exposure, tooth or chain geometry, and any wear pattern that could point to damage elsewhere in the assembly.
