ZF 2093.060.003 TRA 16 | OEM Genuine Part

Overview

The ZF 2093.060.003 TRA 16 is a genuine OEM component engineered for the final drive assembly of heavy-duty construction machinery transmissions. This part functions as a critical load-bearing element within the planetary gear set, ensuring precise torque distribution from the differential to the axle shafts. The SKU 2093.060.003 is specifically designed to maintain the structural integrity of the drivetrain under extreme operating conditions, such as those encountered in wheel loaders and graders. When installed alongside a 2093109024 DIFFERENTIAL, it helps synchronize rotational speeds between the left and right wheels, reducing mechanical stress on the transmission housing.

Symptoms of Failure

• Intermittent gear slipping under load: A worn 2093.060.003 can cause the transmission to momentarily lose power transfer when climbing grades or hauling heavy payloads, often accompanied by a high-pitched whine.
• Oil leaks near the axle flange: Degradation of the sealing surface on this part leads to visible hydraulic fluid seepage, typically noticed after extended operation in dusty environments.
• Vibration during low-speed turns: When the part’s internal splines wear unevenly, operators may feel a rhythmic shudder through the chassis, especially when maneuvering in tight construction sites.
• Metallic debris in transmission fluid: Advanced wear generates fine steel particles that contaminate the oil, detectable during routine filter inspections or fluid changes.

Technical Specifications

Compatibility

This genuine ZF part is engineered for integration into the WG180, WG200, and WG211 transmission series commonly found in construction machinery. It is a direct replacement for the final drive sun gear in models such as the ZF 4WG-180 and 4WG-200, which power articulated dump trucks and compactors. For complete axle assembly, pair this component with a 2093209095 DIFFERENTIAL and a 2093309071 DIFF.HOUSING to ensure proper alignment. The 0750117075 TAPER ROLLER BEARING is also required to support axial loads during high-torque operations.

Frequently Asked Questions

Q: How do I verify if the 2093.060.003 is the correct part for my ZF WG200 transmission?
A: Check the stamped serial number on the transmission housing near the axle flange. The TRA 16 designation should match the final drive ratio listed in your equipment’s service manual. Cross-reference with the 2093109024 DIFFERENTIAL to confirm spline count compatibility.

Q: Can I replace only the 2093.060.003 without replacing the taper roller bearing?
A: It is strongly recommended to install a new 0750117075 TAPER ROLLER BEARING simultaneously, as worn bearings accelerate uneven wear on the new part. Reusing old bearings often leads to premature failure within 500 operating hours.

Q: What torque specification is required for the retaining nut on this part?
A: For the 2093.060.003 in a WG180 series, the final drive nut should be torqued to 450 Nm (332 ft-lbs) with thread locker applied. Always consult the ZF service bulletin for your specific model variant.
