Overview
The ZF 0730.107.694 WASHER is an OEM genuine shim component engineered for precision load distribution within heavy-duty construction machinery transmissions. This hardened steel washer sits between planetary gear sets and bearing races in the differential housing assembly, ensuring correct axial clearance and preventing metal-on-metal contact under extreme torque loads. As a factory-specification part, SKU 0730.107.694 guarantees exact dimensional tolerances required for ZF power transfer systems. When installed alongside the 5838109012: DIFFERENTIAL, this washer maintains proper gear mesh alignment and extends the service life of surrounding rotating components.
Symptoms of Failure
- Transmission oil seepage at axle housing seals – A worn 0730.107.694 washer allows excessive end-play, distorting the 5838300626: DIFFERENTIAL HOUSING seal surface and causing gradual fluid loss.
- Low-speed gear rumbling or whine – Thinning of the washer increases clearance between the 0750117075: TAPER ROLLER BEARING and differential side gear, producing audible vibration during loader or excavator operation.
- Intermittent drive engagement hesitation – Degraded washer thickness alters preload on the 2093209023: DIFFERENTIAL assembly, causing delayed power transfer when shifting between forward and reverse.
- Metallic debris in transmission fluid – Complete washer fracture releases hardened steel fragments into the oil circuit, accelerating wear on planetary gears and clutch packs.

Frequently Asked Questions
Q: Can I reuse the 0730.107.694 washer during a differential rebuild?
A: No. This hardened washer compresses slightly during initial torque application and must be replaced with a new OEM part to maintain correct preload on the taper roller bearing and differential assembly.
Q: How do I identify the correct thickness for my ZF transmission?
A: Measure the axial gap between the differential housing and bearing race using a feeler gauge. The 0730.107.694 washer is 2.0 mm thick; if your gap exceeds 2.15 mm, stack an additional 5838300818: THRUST WASHER to achieve proper clearance.
Q: Will this washer fit the ZF 4WG-200 transmission?
A: Yes. The 0730.107.694 is compatible with 4WG-200, 6WG-250, WG180, and WG200 series when used in the differential side gear position. Always verify housing bore diameter before installation.
