High-Quality Replacement Driveline Parts by — PTC Drivelines
The front driveshaft is the final section of the driveline before torque reaches the front axle on a Komatsu WA600-6 or WD600-6, which means it's also the section that takes the most direct hit from uneven terrain and heavy bucket loads. The PTC 2021 Driveshaft (OEM: KOMATSU 426-20-33112) 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 connects the front-intermediate section to the front axle input, completing the run of driveline components that power the front wheels. Because it sits right before the axle, wear here tends to show up as vibration or clunking felt at the very front of the machine, particularly during hard turns or when the loader is under heavy load. It's built with precision-balanced tubing and forged yokes at each end, designed to absorb that shock loading over years of heavy-duty service.
Every PTC 2021 is manufactured from high-grade steel tubing and dynamically balanced as a complete assembly. We check each unit against OEM drawings before it ships, and an inspection report is available on request.
