Overview
The ZF 0730.104.380 WASHER is an OEM genuine shim component engineered for precise axial clearance control within heavy-duty construction machinery transmissions. This hardened steel washer sits between the planetary gear set and the 2094101014: TRANSMISSION HOUSING, ensuring correct end-play tolerances during clutch pack engagement. As a load-bearing spacer, it prevents metal-to-metal contact between rotating assemblies and stationary housing surfaces. The SKU 0730.104.380 is specifically designed to maintain hydraulic pressure integrity by stabilizing the adjacent 2094301046: HOUSING component under high-torque conditions. Without this precisely machined washer, gear train alignment degrades rapidly, leading to premature bearing failure in ZF power shift transmissions.
Symptoms of Failure
- Transmission oil leaks at housing seam – When the 0730.104.380 washer wears beyond 0.2mm tolerance, the 2094298053: HOUSING shifts, breaking the seal between the 0630361034: SEALING CAP and the main case.
- Intermittent gear slipping under load – A collapsed washer reduces clutch pack clamping force, causing torque loss during excavation or grading operations.
- Metallic grinding noise from transmission sump – Worn washer fragments contaminate the oil, scoring planetary gear teeth and bearing races.
- Erratic shift timing in forward/reverse – Axial play from a degraded washer disrupts hydraulic valve timing, delaying clutch engagement by 0.5–1.5 seconds.

Compatibility
This genuine ZF washer is primarily used in the WG180, WG200, and WG210 series power shift transmissions found in wheel loaders, dozers, and excavators from manufacturers like Liebherr, Caterpillar, and Volvo CE. It also fits the 4WG-180 and 4WG-200 variants where axial shimming between the sun gear and 2094301071: COVER is required. Always verify the stack height using the 0631306670: CYLINDRICAL PIN alignment tool during installation. For final torque specs, pair with the 0636011356: HEXAGON SCREW fasteners.
