Overview
This OEM genuine ZF 0730.110.015 WASHER is a precision-engineered component designed to maintain critical axial clearances within the differential and final drive assemblies of heavy-duty construction machinery transmissions. Positioned between rotating gears and stationary housings, this hardened steel washer absorbs thrust loads and prevents metal-on-metal contact, ensuring long-term durability. The SKU 0730.110.015 is a factory-spec replacement part that restores original tolerances when servicing ZF power shift transmissions. It works in concert with the 5838109012: DIFFERENTIAL to evenly distribute axial forces during high-torque operations.
Symptoms of Failure
- Transmission oil leaks at the axle housing interface: A worn 0730.110.015 washer allows excessive end-play, breaking the seal between the differential housing and axle tube, leading to visible fluid seepage.
- Intermittent gear slipping under load: When this washer loses its precise thickness, the 0750117075: TAPER ROLLER BEARING loses preload, causing momentary loss of drive power during excavation or grading.
- Metallic grinding noise from the differential area: Thrust washer degradation permits the 2093209023: DIFFERENTIAL gears to contact the housing, producing a distinct scraping sound during turns.
- Premature wear on the differential housing bore: A collapsed washer allows the axle shaft to wobble, scoring the 5838300626: DIFFERENTIAL HOUSING and requiring costly machining.

Frequently Asked Questions
Q: Can I reuse the old 0730.110.015 washer during a rebuild?
No. This washer is a single-use crush-type component. Reusing it will result in incorrect bearing preload and rapid failure of the 0750117075: TAPER ROLLER BEARING.
Q: How do I verify the correct thickness of this washer?
Measure the stack height of the differential assembly with a depth micrometer. The 0730.110.015 is available in 0.1 mm increments; select the one that achieves 0.05-0.10 mm of end-play when torqued.
Q: Does this part fit ZF 4WG-200 transmissions?
Yes. It is a direct replacement for the factory thrust washer in the output differential section of 4WG-200, 4WG-210, and 4WG-310 models.
