High-Quality Replacement Driveline Parts by — PTC Drivelines
On the WA600-3R, the front and centre sections of the driveline share a single driveshaft rather than being split into separate parts, which is a bit different from how the newer WA600-6 handles this run. The PTC 2037 Driveshaft (OEM: KOMATSU 426-20-12110) is machined to match the original in every dimension, so it installs in place of the factory part without any modification to the machine.
This shaft covers the span from the transmission through the centre of the frame and out toward the front axle, carrying torque across what's typically the longest section of the driveline. Because it spans such a long run, it's also the section most likely to show vibration first if it's starting to wear — a small amount of imbalance here tends to be more noticeable in the cab than the same wear would be in a shorter section. It's built with precision-balanced tubing and forged yokes to handle that span reliably under continuous loader duty.
Every PTC 2037 is manufactured from high-grade steel tubing and dynamically balanced as a single, complete assembly rather than pieced together. Units are checked against OEM drawings before dispatch, and an inspection report is available on request.
