High-Quality Replacement Driveline Parts by — PTC Drivelines
PTC 2341 is engineered as a direct cross-reference to the OEM part of Komatsu 566-20-71000, designed for the front driveline position on heavy-duty rigid dump trucks used across mining and quarry fleets. The shaft tube is fabricated from high-tensile alloy steel and precision-formed to match OEM wall thickness and diameter, ensuring it withstands the repeated torque spikes and torsional stress typical of front-mounted propeller shafts. Yoke ends are forged and machined to close tolerances, allowing accurate alignment with the mating spider assembly and transmission output.
Before dispatch, each PTC 2341 unit undergoes dynamic balancing to control vibration at operating speeds, protecting downstream bearings, seals, and transmission components from premature stress. Combined with self-lubricated spider joints, this driveshaft supports longer intervals between workshop interventions. Produced under ISO 9001:2015 quality management with dimensional verification against Komatsu HD 325-6 / 7ROEM specification, PTC 2341 gives fleet maintenance teams a reliable, ready-to-install replacement without requiring custom fabrication or fitment adjustment.
