High-Quality Replacement Driveline Parts by — PTC Drivelines
The PTC3003 Wheel Nut is specifically designed to provide reliable clamping power and unmatched wheel seating stability on the most challenging jobsites with Komatsu heavy-duty off-highway dump trucks. This high-grade fastener is specially developed to fit OEM part number 569-22-72870 perfectly, ensuring flush fitment when installing with wheel rims and hub studs and eliminating assembly fitment concerns.
Heavy haulage trucks have to withstand a lot of dynamic loads, high lateral cornering forces, constant ground shock, and severe cyclic thermal loads. The PTC3003 is designed to maintain the initial clamp tension, which will keep the rim from moving, the stud from shearing, the thread from deteriorating, and the hub from loosening during full-load haul cycles.
Precision thread machining of each fastener and special heat treatment to assure exact thread pitch alignment and superior resistance to mud, abrasive grit, and moisture. The close manufacturing tolerance ensures that the torque is applied uniformly, minimizes thread wear when changing wheels, and simplifies routine fleet maintenance.
