Overview
This OEM genuine ZF 2093.070.024 TRA 20 is a critical internal component designed for heavy-duty construction machinery transmissions. Positioned within the differential assembly of ZF drive axles, this part functions as a precision-machined thrust element that manages axial loads and maintains correct gear alignment under extreme torque conditions. The SKU 2093.070.024 is engineered to exact OEM tolerances, ensuring seamless integration with the surrounding drivetrain components. When installed alongside a 2093109032: DIFFERENTIAL, it helps distribute rotational forces evenly, reducing stress on the gearset and extending service intervals for your equipment.
Symptoms of Failure
- Persistent oil seepage around the axle housing: When the 2093.070.024 wears, its sealing surface degrades, causing hydraulic fluid to escape. This is often noticed as a slow drip after the machine sits overnight.
- Intermittent gear slipping under load: A worn TRA 20 allows excessive axial play, leading to momentary loss of power transfer when the excavator or loader encounters heavy resistance.
- Metallic grinding noise during turns: As the part loses its dimensional stability, it fails to properly support the 0750117075: TAPER ROLLER BEARING, resulting in audible chatter from the differential housing.
- Increased backlash in the driveline: Operators may feel a noticeable clunk when shifting between forward and reverse, indicating that the 2093.070.024 can no longer maintain tight gear mesh.

Compatibility
This ZF 2093.070.024 TRA 20 is primarily compatible with ZF WG180, WG200, and WG250 series transmissions commonly found in wheel loaders, telehandlers, and graders. It also fits select APL and HP series axles used in articulated dump trucks. For proper installation, ensure the mating 2093209094: DIFFERENTIAL and 2093309078: DIFF.HOUSING are inspected for wear. Always replace the thrust washer and spring pin simultaneously to guarantee optimal load distribution.

Frequently Asked Questions
Q: Can the ZF 2093.070.024 be reused after a transmission overhaul?
A: No. This is a wear item that should always be replaced with a new OEM part during rebuilds. Reusing it risks premature failure of the differential and bearings.
Q: What tools are needed to install this TRA 20 component?
A: Standard socket set, a bearing puller, and a torque wrench calibrated to ZF specifications. A press may be required to seat the part flush against the differential housing.
Q: How does this part interact with the 0750117075 taper roller bearing?
A: The TRA 20 provides the precise axial preload needed for the taper roller bearing to operate without excessive heat or play. If the 2093.070.024 is worn, the bearing will fail rapidly.
