High-Quality Replacement Driveline Parts by — PTC Drivelines
`Designed for the Komatsu HD785-7 Off-Highway Rigid Dump Truck, the PTC2082 Rear Yoke Assembly ensures consistent torque transmission and robust drive connectivity in challenging applications. Designed for continuous duty in demanding applications like open-pit mining, quarry work, and heavy earthmoving, this has been engineered to be an exact fit for OEM part 561-20-72200 with zero driveline guesswork.
The heavy-duty haul trucks are subjected to high torsional loading, shock loading, severe vibration, and structural fatigue over a number of cycles. The PTC2082 is designed for the maximum payload and will provide structural integrity and joint stability, eliminating excessive driveline play and joint wear on connecting universal joints, driveshafts, and powertrain inputs.
Each machine is precision manufactured, with all interfaces—splines and joints—at OEM tolerances to resist extreme harsh environments of mud, dust, and deep ruts. This allows for efficient power delivery, minimizes unplanned downtime of the driveline, and simplifies long-term fleet maintenance planning.
