High-Quality Replacement Driveline Parts by — PTC Drivelines
A Komatsu WA500-3 that's vibrating or knocking near the back of the machine often points to the rear driveshaft rather than anything up front. The PTC 2026 Driveshaft (OEM: KOMATSU 425-20-24111) replaces this section like-for-like, machined to the same dimensions as the original so it bolts straight in without any modification to the machine.
This shaft carries torque from the transfer case back to the rear axle, powering the rear wheels independently of the front driveline run. Because it operates on its own separate path, a problem here won't necessarily show up as vibration through the whole machine the way a front-section issue might — it's often more localized, felt as noise or shudder specifically toward the rear when the loader is working under load or turning tightly. The forged yokes and balanced tube design are built to handle that torque path reliably over years of heavy-duty service.
Every PTC 2026 is manufactured from high-grade steel tubing and balanced as a complete assembly rather than in separate pieces. We check each unit against OEM drawings before it ships, and an inspection report is available on request.
