High-Quality Replacement Driveline Parts by — PTC Drivelines
The universal joint is subject to some of the highest torques of all Komatsu's dozers, and the spider bearing in the centre of the universal joint experiences a lot of the action. Driveline vibration or joint play can be an early indicator that a fleet team running Komatsu D475A units in mining and quarry operations is having issues with this component that can lead to more significant repair costs. PTC 1093 is designed to be an exact fit for the Komatsu 198-20-62100, with the same cross diameter, trunnion length and bearing seat clearance, allowing it to install directly into the existing joint housing with no rework. The cross is made of high-strength alloy steel and is case hardened in the bearing contact surfaces to withstand high impact loads found in heavy dozing and ripping applications. A dust- and grease-tight design ensures the grease stays within the unit as dust and debris invade a large-scale earthmoving operation. PTC 1093 is available for use with scheduled rebuilds as well as for emergency repairs to drivelines on the Komatsu D475A.
