High-Quality Replacement Driveline Parts by — PTC Drivelines
PTC 2229 is a referred to OEM part that replaces Komatsu 56B-20-12902, which is the carrier of the drive between the axle output and the wheel end in the articulated dump trucks under mining and quarry conditions. The final torque is delivered here, and in this segment of the drive, the tube is constructed of high-tensile alloy steel that is sized to fit the same diameter as the OEM and wall thickness to ensure that the tube retains its strength with load plus traction forces acting here. Forged yoke ends are turned to spline engagements precise to maintain the axle output and wheel hub assembly in line.
Dynamically balancing each shaft at the factory ensures vibration at this outer drive line location is controlled to prevent early wear of wheel bearing housings and axle output seals. On top of sealed, self-lubricated spider joints, PTC 2229 eliminates the necessity of regular manual greasing during service intervals. Made to ISO 9001:2015 quality specifications and dimensionally verified to Komatsu HM400-2R, this driveshaft is fabricated as a direct, workshop-ready replacement of the axle-to-wheel portion of the driveshaft.
