ZF 2093.060.053 TRA 16 | OEM Genuine Part

Overview

This OEM genuine ZF 2093.060.053 TRA 16 is a critical internal component designed for heavy-duty construction machinery transmissions. Specifically, it functions as a precision-machined spacer or thrust element within the differential housing assembly, ensuring correct axial clearance and load distribution between rotating gear sets. The SKU 2093.060.053 sits directly between the differential carrier and the axle bevel gear, maintaining proper gear mesh depth and preventing metal-on-metal contact under high torque loads. As a genuine ZF part, it guarantees exact metallurgical composition and dimensional tolerances required for long service life in excavators, wheel loaders, and graders.

Symptoms of Failure

• Excessive differential housing oil leaks – When the 2093.060.053 wears or distorts, it allows lubricant to bypass seals, causing visible drips around the axle housing flanges.
• Intermittent gear slipping under load – A worn TRA 16 spacer reduces preload on the differential assembly, leading to momentary loss of traction when climbing grades or pushing heavy material.
• Metallic grinding noise during turns – As the part degrades, axial play increases, allowing the differential gears to contact the housing, producing a distinct grinding sound during low-speed maneuvers.
• Premature bearing failure – Incorrect clearance from a failed 2093.060.053 places abnormal stress on the 0750117075: TAPER ROLLER BEARING, accelerating wear and generating fine metallic debris in the oil.

Technical Specifications

Compatibility

This genuine ZF 2093.060.053 TRA 16 is engineered for use in the following ZF transmission models commonly found in construction machinery: WG180, WG200, WG210, and WG250 series. It is also compatible with certain variants of the ZF-ECOMIX and ZF-ERGOPOWER drivelines used in mid-size wheel loaders and telehandlers. Always verify your transmission serial number against the OEM parts catalog before ordering.

During installation, this spacer works in concert with the 2093109029: DIFFERENTIAL assembly and the 2093209094: DIFFERENTIAL carrier to maintain proper gear alignment. The 2093309078: DIFF.HOUSING provides the structural envelope that contains these rotating components under extreme loads.

Frequently Asked Questions

Q: How do I know if the 2093.060.053 TRA 16 is the correct part for my ZF transmission?
A: Check the stamped part number on your existing spacer ring. This component is used exclusively in ZF WG180, WG200, WG210, and WG250 series transmissions. Cross-reference your transmission model code with the OEM parts manual to confirm fitment.

Q: Can I reuse the old TRA 16 spacer if it looks undamaged?
A: ZF recommends always replacing this thrust ring during any differential overhaul. Even minor wear can alter preload settings, leading to accelerated failure of the 0750117075: TAPER ROLLER BEARING and other driveline components.

Q: What torque specification should I use when installing the differential housing with this part?
A: For the 2093309078: DIFF.HOUSING bolts, use 120 Nm (88 ft-lbs) with thread locker applied. Always consult your specific ZF service manual for exact values, as variations exist between transmission series.
