ZF 0730.301.767 WASHER | OEM Genuine Part

Overview

The ZF 0730.301.767 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearances within heavy-duty construction machinery transmissions. This hardened steel washer sits between rotating gear assemblies and the transmission housing, acting as a load-bearing surface that prevents metal-on-metal contact. Specifically, it is installed in the differential and final drive sections of ZF power shift transmissions, where it manages thrust loads and ensures consistent gear alignment. The SKU 0730.301.767 is manufactured to ZF’s exacting tolerances, guaranteeing a perfect fit and long service life in demanding off-highway applications.

Symptoms of Failure

When the ZF 0730.301.767 WASHER wears beyond specification, operators will notice several distinct performance issues. Transmission oil leaks from the axle housing often appear first, as the worn washer allows excessive lateral movement that compromises seal integrity. Intermittent gear slipping under load occurs when axial play increases, causing the gear train to lose proper mesh. Metallic grinding noises during turns indicate the washer has thinned to the point where the 5838109012: DIFFERENTIAL components are contacting the housing. Finally, premature bearing failure in the final drive section is a common secondary symptom, as the worn washer cannot properly distribute thrust loads to the 0750117075: TAPER ROLLER BEARING.

Technical Specifications

Compatibility

This washer is a standard component in ZF’s WG series power shift transmissions used in construction machinery. It is directly compatible with the WG180, WG200, and WG250 models, where it is installed between the differential carrier and the housing. The part also fits select WG160 and WG300 variants when used with the 2093209023: DIFFERENTIAL assembly. For proper installation, always pair this washer with the 5838300626: DIFFERENTIAL HOUSING to ensure correct axial positioning.

Frequently Asked Questions

Q: How do I know if the 0730.301.767 washer needs replacement?
A: Measure the thickness with a micrometer. If it is below 2.3 mm, or if you observe any of the failure symptoms listed above (oil leaks, grinding, gear slip), replace it immediately. Always inspect the mating surfaces on the differential housing for scoring.

Q: Can I reuse this washer during a transmission rebuild?
A: No. ZF specifies that the 0730.301.767 is a single-use component. The hardened steel surface work-hardens during initial installation, and reusing it will lead to accelerated wear and potential differential failure.

Q: Is this washer compatible with aftermarket differentials?
A: It is designed specifically for OEM ZF differentials. If you are using an aftermarket unit, verify that the inner and outer diameters match exactly. For best results, always pair it with genuine ZF components like the 5838300626 housing.
