High-Quality Replacement Driveline Parts by — PTC Drivelines
The PTC 1041 Rear Spider Assembly is designed as an exact cross-reference to the OEM: Komatsu 561-20-62100, designed to fit the rear part of the propeller shaft in heavy-duty rigid dump trucks. This spider unit is made of high-quality alloy steel and has been exposed to controlled carburising and heat treatment to ensure that it is able to withstand the repeated torsional loading, shock impact and constant angular rotation that this component has to endure in rear drive line applications in the mining and quarry applications. Its needle roller bearings and self-locked bearing cups are adjusted to tight rotational tolerances to ensure that backlash is minimised.
PTC 1041 is sealed with a three-step lockout system to keep out abrasive dust, moisture and debris and retain factory-filled lubrication to offer a long maintenance-free service. This minimises the number of visits to the workshop and helps to maintain high equipment uptime in duty cycles. Produced to ISO 9001:2015 regulated operations and checked to OEM dimensional requirements, PTC 1041 is a reliable and pre-assembled rear spider assembly on the Komatsu HD785 series, with each production batch being consistent in quality.
