SX-7373 TIMKEN Rear Inner Differential Pinion Race Au

Review TIMKEN Rear Inner Differential Pinion Race For International Au

The Timken SX-7373 rear inner differential pinion race is an essential component for the 1971-1973 International Harvester 1210 AU models. This product is designed to provide superior performance and durability for your vehicle's differential assembly.

The pinion race is the track or groove in which the pinion shaft moves, transferring power from the transmission to the differential gears. Timken's SX-7373 pinion race is manufactured using high-quality, heat-treated steel to ensure strength and resistance to wear. The race is also precision ground to provide a perfect fit for the pinion shaft and ensure smooth operation.

This pinion race also features Timken's proprietary rolling contact ball bearing design. This design utilizes a series of small, hard balls that roll between the pinion shaft and the race, reducing friction and wear. The balls are held in place by a thin film of lubricant, allowing for quiet and efficient operation.

Additionally, the SX-7373 pinion race is designed with a double lip seal to prevent leakage and contamination of the differential fluid. This helps to maintain the lubrication and cooling properties of the fluid, ensuring the longevity and performance of the differential assembly.

Overall, the Timken SX-7373 rear inner differential pinion race is an essential upgrade for any 1971-1973 International Harvester 1210 AU. Its superior strength, durability, and efficiency make it an excellent choice for those seeking to improve the performance and reliability of their vehicle's differential assembly.
