KOMATSU 426-20-24121 OE Part Manufacturers in India

Where the front-and-centre shaft on the WA600-3R covers the long haul from the transmission out to the front axle, the rear driveshaft handles an entirely separate job — running from the transfer case back to the rear axle on its own dedicated path. The PTC 2038 Driveshaft (OEM: KOMATSU 426-20-24121) is machined to match the original Komatsu WA600-3R part exactly, so it installs in the factory position without any modification needed.

Because this shaft powers the rear wheels independently of the front driveline run, issues here tend to stay fairly localised rather than showing up as vibration through the whole machine. Operators usually notice it as noise or shudder concentrated toward the back end, often more pronounced during tight turning or when reversing under load, since the rear axle sees different steering geometry than the front. Forged yokes and balanced tubing are built into the shaft to hold up against that turning stress over years of loader work.

Every PTC 2038 is manufactured from high-grade steel tubing and dynamically balanced as a single complete unit. Each batch is checked against OEM drawings before dispatch, and an inspection report is available on request.
