Overview
This genuine ZF 0730.108.455 WASHER is a precision-engineered component designed to maintain correct axial clearance and load distribution within heavy-duty construction machinery transmissions. Positioned between rotating assemblies, this OEM washer prevents metal-to-metal contact and ensures consistent clamping force under high torque conditions. The SKU 0730.108.455 is commonly found in final drive and differential assemblies, where it works in concert with the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING to manage end-play and reduce vibration.
Symptoms of Failure
- Transmission oil seepage around the differential housing: A worn 0730.108.455 washer can distort the sealing surface, causing fluid to escape past the 5838300626: DIFFERENTIAL HOUSING gasket.
- Gear whine or rumbling noise during turns: Excessive axial play from a flattened washer allows the 2093209023: DIFFERENTIAL gears to misalign, producing audible noise under load.
- Intermittent gear slipping under heavy load: When the washer loses its specified thickness, clamping force drops, leading to momentary torque loss in the driveline.
- Metallic debris in transmission fluid: A fractured washer sheds particles that contaminate the oil and accelerate bearing wear.

Compatibility
This washer is engineered for ZF WG180, WG200, and WG250 series power shift transmissions used in wheel loaders, graders, and excavators. It also fits select ZF ECCOMIX and ERGOPOWER drivelines. Always verify fitment against your transmission serial number, as the washer is often paired with the 5838300811: THRUST WASHER and the 5838300721: AXLE BEVEL GEAR in the final drive stack.

Frequently Asked Questions
Q: Can I reuse the 0730.108.455 washer during a rebuild?
A: No. This washer is a single-use crush-type component. Reusing it will not provide the correct clamping force and may lead to premature differential failure.
Q: How do I know if this washer fits my ZF WG200 transmission?
A: Check the transmission model plate near the PTO housing. The 0730.108.455 is standard in WG200 series with serial numbers starting after 2015. For older units, verify the thickness against your original part.
Q: What tools are needed to replace this washer?
A: You will need a torque wrench, a bearing puller, and a micrometer to measure the old washer thickness. Always replace the 5838300818: THRUST WASHER simultaneously to ensure proper stack height.
