Overview
The ZF 2094.311.046 RING is an OEM genuine precision-engineered component designed for heavy-duty construction machinery transmissions. This ring functions as a critical sealing and alignment element within the planetary gear set or clutch pack assembly, ensuring proper hydraulic pressure containment and rotational stability. The SKU 2094.311.046 is specifically manufactured to ZF’s exacting tolerances, preventing fluid bypass and maintaining optimal gear engagement under extreme loads. It sits between the 2094101011: TRANSMISSION HOUSING and the 2094301045: HOUSING, forming a sealed interface that directs oil flow to clutches and brakes.
Symptoms of Failure
- Hydraulic pressure drop during gear shifts: A worn 2094.311.046 ring allows pressurized transmission fluid to leak past sealing surfaces, causing delayed or harsh engagement in forward and reverse gears.
- Internal transmission oil leaks: Visible fluid seepage around the housing mating area indicates the ring has lost its compressive integrity, often accompanied by low fluid levels on the dipstick.
- Erratic clutch pack operation: When this ring deforms or cracks, it fails to properly route oil to specific clutch packs, resulting in intermittent slipping or unexpected neutral conditions during operation.
- Metallic debris in oil filter: Advanced ring wear generates fine metal particles that circulate through the transmission, accelerating damage to the 0635460022: BALL check valve and other precision components.

Compatibility
This ring is engineered for ZF WG-series powershift transmissions commonly used in wheel loaders, excavators, and telehandlers. Primary compatible models include the WG180, WG200, and WG210 series. It also fits select Ecomat 2 and Ecomat 4 transmissions from the 1990s-2010s production era. Always verify the ring’s orientation relative to the 2094301044: COVER plate during installation, as improper seating can cause immediate failure.
