High-Quality Replacement Driveline Parts by — PTC Drivelines
The cause of Komatsu D155A dozer downtime is often a single component that is easy to overlook, the universal joint on the transmission connection to its final drive. Operators will often identify age-related joint conditions by vibration through the cab or an increased lag when moving the lever to change direction while under load. PTC 2034 is designed to be a direct cross-reference to Komatsu 175-20-00050 / 17A-20-11201, utilising the same bolt pattern, identical spider dimensions, and the same drive shaft coupling as to be dropped in the driveline with no modifications.
Forged of alloy steel, PTC 2034 is heat treated to endure the shock loading while grading, ripping, and push loading, commonly experienced during the course of work, and uses sealed needle bearings to keep the dust and dirt coming through the dozer door from destroying the joint. PTC 2034 is factory balanced to reduce the vibration transmitted into the transmission output and final drive input shafts. For the multi-job Komatsu D155A end user, this will be a welcome and durable OEM-compatible universal joint that can be kept stockpiled to maintain dozer availability.
