Overview
The ZF 2093.070.014 TRA 20 is a critical OEM genuine component designed for heavy-duty construction machinery transmissions. This part functions as a precision-machined thrust element within the differential assembly, managing axial loads and ensuring smooth torque distribution under extreme operating conditions. Positioned directly within the final drive housing, the SKU 2093.070.014 interfaces with the axle bevel gear set to maintain proper gear mesh alignment. When paired with a 2093109022 DIFFERENTIAL, this component forms the backbone of reliable power transfer in wheel loaders and graders.
Symptoms of Failure
- Low-speed gear grinding noise: A distinct metallic scraping sound during tight turns indicates the 2093.070.014 has worn beyond tolerance, often accompanied by vibration through the driveline.
- Differential oil leaks at the axle flange: When this thrust element degrades, it can cause misalignment that forces fluid past seals, leaving visible puddles under parked equipment.
- Intermittent wheel lock-up during operation: Worn surfaces allow the 0750117075 TAPER ROLLER BEARING to shift, creating sudden resistance that feels like the brakes are dragging.
- Increased backlash in the drivetrain: Operators notice a delayed response when shifting from forward to reverse, a clear sign the part has lost its dimensional integrity.

Compatibility
This genuine ZF part is engineered for the WG180, WG200, and WG210 series transmissions commonly found in construction machinery. It directly replaces the thrust washer in the differential carrier assembly of models like the ZF 4WG-180 and 4WG-200. For complete differential rebuilds, always inspect the 2093209096 DIFFERENTIAL and the 2093309073 DIFF.HOUSING for matching wear patterns.

Frequently Asked Questions
Q: Can the 2093.070.014 be reused during a differential rebuild?
A: No. This is a wear-critical component that must be replaced whenever the differential is disassembled. Reusing it risks accelerated failure of the 2093109022 DIFFERENTIAL assembly.
Q: What tools are required to install this part?
A: Installation requires a hydraulic press and a dial indicator to verify axial clearance. Always measure the preload on the 0750117075 TAPER ROLLER BEARING after fitting the new thrust element.
Q: Does this part fit ZF 4WG-200 transmissions from 1998?
A: Yes, the 2093.070.014 is backward-compatible with all WG200 series transmissions manufactured after 1995, provided the 2093309073 DIFF.HOUSING has not been modified.
