ZF 2093.060.061 TRA 16 | OEM Genuine Part

Overview

The ZF 2093.060.061 TRA 16 is a genuine OEM transmission component engineered for the demanding environment of construction machinery. This part functions as a critical internal gear or shaft assembly within the planetary gear set of ZF’s heavy-duty powershift transmissions. Its primary role is to manage torque distribution and rotational speed between the input shaft and the differential housing. The SKU 2093.060.061 is precision-machined to OEM tolerances, ensuring seamless integration with adjacent drivetrain components such as the 2093109055: DIFFERENTIAL and the 2093209094: DIFFERENTIAL assembly. Without this part, the transmission cannot maintain proper gear engagement under load.

Symptoms of Failure

When the ZF 2093.060.061 begins to wear, operators typically notice three distinct failure modes. First, intermittent gear slipping under heavy load occurs, particularly when the machine is climbing or digging. Second, metallic grinding noises from the transmission housing indicate surface fatigue on the gear teeth. Third, erratic shifting between forward and reverse becomes common as the part loses its indexing capability. Fourth, contaminated transmission fluid with bronze or steel particles signals that the TRA 16 component is shedding material, which can quickly damage the 0750117075: TAPER ROLLER BEARING and the 2093309078: DIFF.HOUSING.

Technical Specifications

Compatibility

This genuine ZF part is designed for use in the WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, dozers, and graders. It also fits select variants of the ZF 4WG-200 and 6WG-200 models. The 2093.060.061 interfaces directly with the differential assembly, so it is frequently replaced alongside the 2093109055: DIFFERENTIAL and the 2093209094: DIFFERENTIAL unit. Always verify your transmission serial number before ordering.

Frequently Asked Questions

Q: How do I know if the 2093.060.061 is the correct replacement for my ZF transmission?
A: Verify your transmission model plate. This part is standard in WG180, WG200, and WG210 series. If your unit has a 24-spline input shaft and a 98mm outer diameter gear pocket, the TRA 16 is the correct fit.

Q: Can I replace this part without removing the entire transmission?
A: In most construction machinery, the 2093.060.061 is accessible after removing the differential cover and the 2093309078: DIFF.HOUSING. However, we recommend a full transmission teardown if the 0750117075: TAPER ROLLER BEARING shows wear.

Q: What is the typical lifespan of this TRA 16 gear assembly?
A: Under normal operating conditions with proper fluid maintenance, the 2093.060.061 lasts 8,000 to 12,000 hours. Contaminated oil or shock loading can reduce this to 4,000 hours.
