Overview
This genuine ZF 0730.110.019 WASHER is a precision-engineered component designed to maintain critical axial clearances within heavy-duty construction machinery transmissions. As an OEM part, it functions as a load-spreading interface between rotating assemblies, preventing metal-on-metal contact that leads to premature wear. The SKU 0730.110.019 is specifically positioned in the differential and final drive sections of ZF power shift transmissions, where it absorbs thrust loads and stabilizes gear alignment. When installed alongside a 5838109009: DIFFERENTIAL, this washer ensures consistent torque distribution across the drivetrain.
Symptoms of Failure
- Transmission oil leaks at axle seals: A worn 0730.110.019 washer allows excessive end-play, which distorts seal contact surfaces and causes hydraulic fluid seepage around the differential housing.
- Gear slipping under load in construction equipment: When the washer loses its original thickness, axial play increases, leading to intermittent gear disengagement during heavy excavation or grading operations.
- Metallic grinding noise during turns: Degraded washer material permits the 0750117075: TAPER ROLLER BEARING to shift, creating audible friction between the differential and housing components.
- Vibration in the driveline at low speeds: Uneven washer wear causes the 2093209023: DIFFERENTIAL assembly to wobble, transmitting vibration through the transmission case.

Compatibility
This washer is engineered for ZF power shift transmissions commonly used in wheel loaders, dozers, and graders. It is a direct fit for the WG180, WG200, and WG211 series, where it mounts between the differential carrier and the 5838300626: DIFFERENTIAL HOUSING. The 0730.110.019 also applies to select ZF 4WG-180 and 4WG-200 models, particularly those manufactured after 2005. Always verify clearance with the existing thrust washer stack before installation.

Frequently Asked Questions
Q: Can the ZF 0730.110.019 washer be reused after disassembly?
A: No. This is a single-use crush washer that deforms during initial torque application. Reusing it will result in incorrect preload and rapid failure of the differential bearings.
Q: How do I know if my WG200 transmission needs this washer?
A: If you observe oil weeping from the differential housing flange or hear a clicking sound when turning, the washer has likely compressed beyond its service limit. Measure the installed thickness; if below 2.3 mm, replace it immediately.
Q: Is this washer compatible with the 5838300811 thrust washer?
A: Yes. The 0730.110.019 works in conjunction with the 5838300811: THRUST WASHER to manage axial loads. Both should be replaced simultaneously to maintain proper stack height.
