ZF 0730.300.924 THRUST WASHER | OEM Genuine Part

Overview

The ZF 0730.300.924 Thrust Washer is a precision-engineered OEM genuine component designed to manage axial loads and maintain critical clearances within heavy-duty ZF transmissions. Positioned between rotating gear sets and stationary housings, this washer absorbs end-play forces that would otherwise cause metal-on-metal contact and premature wear. The SKU 0730.300.924 is commonly found in the differential and planetary gear sections of construction machinery transmissions, where it ensures smooth power transfer and reduces friction under high-torque conditions. When paired with a 2093109002: DIFFERENTIAL, this thrust washer helps stabilize the entire gear train, extending the service life of adjacent components.

Symptoms of Failure

When the ZF 0730.300.924 thrust washer wears beyond its tolerance, operators will notice several distinct failure indicators. Transmission gear slipping under load is a primary symptom, as excessive axial play allows gear teeth to lose proper engagement. Metallic grinding noises from the differential housing often accompany worn washers, signaling that hardened steel surfaces are contacting the housing directly. Low oil pressure warnings can also occur when debris from a failing thrust washer clogs internal oil passages. Finally, intermittent driveline vibration during acceleration points to uneven load distribution caused by a compromised washer. If you observe any of these issues, inspect the 0730.300.924 alongside the 0750117075: TAPER ROLLER BEARING, as both components share the same load path.

Technical Specifications

Compatibility

This thrust washer is engineered for ZF heavy-duty transmissions commonly used in construction machinery. It is a direct fit for the ZF WG180, WG200, and WG210 series power shift transmissions. The 0730.300.924 also appears in certain ZF 4WG-200 and 6WG-200 variants, where it supports the differential assembly. For accurate fitment, always verify the part number against your transmission’s serial plate. When rebuilding a differential section, consider replacing the 2093209095: DIFFERENTIAL and the 2093309071: DIFF.HOUSING simultaneously to ensure all mating surfaces are within factory specifications.

Frequently Asked Questions

Q: How do I know if the 0730.300.924 thrust washer is the correct thickness for my ZF transmission?
A: Measure the axial clearance in the differential assembly using a feeler gauge. The factory specification for most WG180/WG200 transmissions is 0.10–0.25 mm end-play. If the clearance exceeds 0.30 mm, replace the washer with the 0730.300.924 or adjust using the alternate 0730300820: THRUST WASHER if a different thickness is required.

Q: Can I reuse the old thrust washer if it shows only minor wear marks?
A: No. Thrust washers work-hardened during initial use and lose their precise flatness. Reusing a worn washer will accelerate damage to the 2093109002: DIFFERENTIAL and the housing. Always install a new OEM genuine part during any rebuild.

Q: What tools are needed to replace the 0730.300.924 thrust washer?
A: Standard socket set, torque wrench, bearing puller, and a dial indicator for measuring end-play. You will also need to remove the 2093309071: DIFF.HOUSING to access the washer. Always consult the ZF service manual for your specific transmission model.
