Overview
This OEM genuine ZF 2093.060.047 TRA 16 is a critical internal component designed for heavy-duty construction machinery transmissions. Specifically, this part functions as a thrust washer or spacer element within the differential assembly of ZF power shift transmissions. It ensures precise axial clearance and load distribution between rotating gear sets, preventing metal-to-metal contact under high torque loads. The SKU 2093.060.047 is engineered to OEM tolerances, guaranteeing a direct fit and long service life in demanding off-highway applications.
Symptoms of Failure
- Excessive axial play in the differential housing: When the 2093.060.047 wears down, you will notice increased end-float in the differential assembly, leading to inaccurate gear meshing.
- Low-frequency growling from the transmission center section: A worn thrust washer causes the 2093109055: DIFFERENTIAL to shift laterally, producing a distinct rumbling noise during load changes.
- Contaminated transmission oil with metallic debris: As the hardened surface of the TRA 16 erodes, fine steel particles will appear in the oil filter, indicating imminent differential failure.
- Intermittent gear slipping under heavy load: Loss of axial preload from this part allows the 0750117075: TAPER ROLLER BEARING to lose its proper seating, causing momentary power loss.

Frequently Asked Questions
Q: Can the 2093.060.047 be reused during a transmission rebuild?
A: No. This is a wear item that must be replaced with a new OEM part. Reusing a worn TRA 16 will cause immediate clearance issues and accelerate damage to the differential housing.
Q: What tools are needed to install this thrust ring?
A: Installation requires a bearing press and a dial indicator to verify axial play. You must also replace the 0750117075: TAPER ROLLER BEARING simultaneously to ensure proper preload.
Q: Does this part fit ZF 4WG-200 transmissions?
A: Yes, the 2093.060.047 is compatible with the 4WG-200 series, provided the differential assembly uses the TRA 16 configuration. Cross-reference your existing part before ordering.
