Overview
The ZF 2094.311.080 SHEET is a precision-engineered structural component designed for heavy-duty construction machinery transmissions. This OEM genuine part serves as a critical sealing and alignment interface within the transmission assembly, ensuring proper oil circulation and preventing contamination between gear stages. Specifically, this sheet component mounts between the main transmission housing and the cover assembly, acting as a gasket surface and flow director for hydraulic fluid. The SKU 2094.311.080 is manufactured to ZF’s exacting tolerances, guaranteeing a leak-free seal under high-pressure operating conditions common in wheel loaders and excavators. When installed alongside the 2094101012 TRANSMISSION HOUSING, this sheet provides the necessary rigidity to maintain gear alignment during torque spikes.
Symptoms of Failure
- Hydraulic oil seepage at transmission mid-section: A worn or warped 2094.311.080 sheet often causes visible oil weeping between the housing halves, particularly after extended operation in high-temperature environments.
- Erratic gear engagement under load: When this sheet fatigues, it can allow slight misalignment of the valve body, leading to delayed or harsh shifting in ZF WG-series transmissions.
- Contaminated transmission fluid: A cracked sheet permits debris ingress from the clutch housing, resulting in accelerated wear of internal components like the 2094301036 HOUSING.
- Increased operating noise from gear train: Loss of sheet integrity reduces damping, causing audible whining or clattering during low-speed maneuvers in construction equipment.

Compatibility
This sheet is engineered for ZF’s heavy-duty transmission families commonly deployed in construction machinery. It is a direct fit for the WG180, WG200, and WG210 series, as well as the 4WG-200 and 6WG-200 variants used in wheel loaders and graders. The 2094.311.080 also integrates with the 2094298057 HOUSING in certain 5-speed configurations. For proper sealing, it must be paired with the 2094301071 COVER to prevent fluid bypass. Always verify your transmission model’s serial number against ZF’s application charts before ordering.
