High-Quality Replacement Driveline Parts by — PTC Drivelines
The PTC2081 Front Yoke Assembly is designed to provide reliable, high-torque power transmission for the Komatsu HD785-7 Off-Highway Rigid Dump Truck in challenging open-pit mining, quarrying, and heavy earthmoving applications. This precision-machined part is built to meet Komatsu's OEM part no. 561-20-71200 and standards of dimensional tolerances for seamless integration with the drivetrain.
The PTC2081 is engineered to withstand the most extreme operational stresses, including heavy impact, maximum payload cycles, and continuous vibration. Its strong build quality ensures that it will not wear out early, break the driveline, or cause any expensive downtime on the field.
In addition, precision manufacturing provides accurate rotational balance and prevents adjacent bearings from being damaged, while a sealing shield seals off internal mechanisms from abrasive rock dust, slurry, and water. The PTC2081 provides ongoing lubrication in the toughest of haul roads and will increase equipment uptime and service life and reduce maintenance intervals for heavy haulage fleets.
