High-Quality Replacement Driveline Parts by — PTC Drivelines
If your Komatsu WA500-3 is showing vibration or noise between the engine and transmission, the engine-side driveshaft is one of the first places to check. The PTC 2027 Driveshaft (OEM: KOMATSU 425-20-11111) is a direct drop-in replacement for the engine-side section of the WA500-3's driveline. Every dimension matches the original, so it bolts straight in without any modification to the machine.
This driveshaft transmits rotational power from the engine's output flange into the transmission input and it is the section that absorbs the initial torque and vibration before it is carried further down the driveline. It's built with precision-balanced tubing and forged yokes at each end, designed to handle the shock loading and misalignment that come with heavy-duty earthmoving work. Over time, driveshafts wear at the yoke and slip-joint areas — if you are seeing uneven wear, cracking or excessive play, that is the signal it is due for replacement.
We manufacture the PTC 2027 from high-grade steel tubing, dynamically balanced as a complete assembly to keep vibration to a minimum at operating speed. Every unit is checked against OEM drawings before dispatch, and we'll provide a full inspection report on request.
