High-Quality Replacement Driveline Parts by — PTC Drivelines
PTC 2084 is manufactured as a cross-reference replacement for Komatsu 561-20-62000 (OEM part), positioned at the rear driveline of heavy-duty rigid dump trucks operating in mining and earthmoving environments. The shaft tube is fabricated from high-tensile alloy steel, sized to match OEM outer diameter and wall thickness so torsional capacity remains consistent with original equipment performance under continuous haul cycles. Forged yoke ends are precision-machined to ensure accurate spline engagement and flange alignment with the mating spider assembly and axle input.
Each unit undergoes factory dynamic balancing before dispatch, minimising vibration transfer at operating speed and helping protect rear axle bearings and seals from accelerated wear caused by shaft imbalance. Working in tandem with sealed, self-lubricated spider joints, PTC 2084 supports extended intervals between manual greasing during routine maintenance. Produced under ISO 9001:2015 quality management and dimensionally verified against OEM Komatsu 561-20-62000, this driveshaft gives fleet maintenance teams a straightforward, ready-to-install replacement for rear driveline servicing on HD785 series equipment.
