Overview
This ZF 0730.109.564 WASHER is an OEM genuine shim component engineered for precise axial clearance control within heavy-duty construction machinery transmissions. Positioned between planetary gear sets and bearing assemblies, this hardened steel washer absorbs thrust loads and maintains critical gear mesh alignment. The SKU 0730.109.564 is specifically designed to prevent metal-to-metal contact in high-torque applications, ensuring the differential assembly operates within factory tolerances. When paired with a 5838109012: DIFFERENTIAL, this washer becomes essential for load distribution across the drivetrain.
Symptoms of Failure
- Transmission oil leaks near the axle housing – A worn 0730.109.564 washer allows excessive end-play, compromising the seal between the 5838300626: DIFFERENTIAL HOUSING and the output shaft, leading to visible fluid seepage.
- Intermittent gear slipping under load – As the washer thins from fatigue, axial clearance increases, causing the 0750117075: TAPER ROLLER BEARING to lose preload, resulting in momentary power loss during excavation or grading.
- Metallic grinding noise during turns – A collapsed washer permits the 2093209023: DIFFERENTIAL gears to contact the housing, producing a distinct grinding sound that worsens with steering input.
- Increased vibration at low RPM – Uneven washer wear creates micro-movements in the planetary carrier, transmitting vibration through the chassis during idle or creep operations.

Compatibility
This genuine ZF washer is a direct replacement for transmissions in the WG series, specifically the WG180, WG200, and WG240 models used in wheel loaders, telehandlers, and excavators. It also fits select ZF 4WG-310 and 6WG-260 variants where the differential assembly requires a 2.5 mm shim. Always verify your transmission serial number before ordering.

Frequently Asked Questions
Q: Can I reuse the 0730.109.564 washer during a rebuild?
A: No. This is a single-use shim that deforms under torque. Always replace it with a new OEM washer to maintain proper bearing preload and prevent differential failure.
Q: How do I measure the correct washer thickness for my ZF transmission?
A: Use a depth micrometer to measure the gap between the bearing race and housing after installing the 0750117075: TAPER ROLLER BEARING. The 0730.109.564 is a standard 2.5 mm shim; if your clearance exceeds 0.1 mm, stack additional shims.
Q: Will this washer fit a ZF 6WG-260 transmission?
A: Yes, the 0730.109.564 is compatible with 6WG-260 models that use the same differential housing as the WG200 series. Cross-reference your housing part number with 5838300626: DIFFERENTIAL HOUSING to confirm.
