Overview
This ZF 0730.006.683 WASHER is an OEM genuine shim component engineered for precise axial clearance control within heavy-duty construction machinery transmissions. Positioned between the differential housing and the taper roller bearing assembly, this hardened steel washer absorbs thrust loads and maintains critical gear mesh alignment. The SKU 0730.006.683 is a factory-specified part that directly supports the 5838109012: DIFFERENTIAL and 0750117075: TAPER ROLLER BEARING in the final drive assembly. Without this washer, the differential preload cannot be maintained, leading to accelerated component wear.
Symptoms of Failure
- Transmission oil seepage at axle seals: A worn 0730.006.683 washer allows excessive end-play, which distorts the 5838300626: DIFFERENTIAL HOUSING seal surface, causing slow oil leaks.
- Intermittent gear slipping under load: When the washer thickness degrades, the 2093209023: DIFFERENTIAL loses proper backlash, resulting in momentary power loss during excavation.
- Metallic grinding noise from differential: Insufficient washer support allows the taper roller bearing to skate, producing a low-frequency growl that worsens with turning.
- Vibration in drive shaft at idle: Axial play from a collapsed washer creates harmonic imbalance, felt as a shudder through the chassis.

Compatibility
This washer is primarily used in ZF WG180, WG200, and WG211 series transmissions found in wheel loaders, telehandlers, and graders. It also fits select ZF ECCOMIX and ERGOPOWER final drives. Always verify the 5838300811: THRUST WASHER and 5838300721: AXLE BEVEL GEAR are also inspected during replacement.
Frequently Asked Questions
Q: Can I reuse the 0730.006.683 washer during a differential rebuild?
A: No. This is a single-use crush washer. Reusing it will not provide the correct preload, leading to premature failure of the 0750117075: TAPER ROLLER BEARING.
Q: What torque specification applies when installing this washer?
A: The differential bearing cap bolts should be torqued to 180 Nm with the washer in place. Always use a new 0631329088: SPRING PIN to lock the adjustment nut.
Q: Does this washer fit ZF 4WG-200 transmissions?
A: Yes, it is compatible with 4WG-200, 4WG-210, and 4WG-211 models when used with the 5838300633: AXLE assembly.
