Overview
The ZF 2094.311.079 SHEET is a precision-formed structural component designed for integration within heavy-duty ZF powershift transmissions used in construction machinery. This OEM genuine part functions as a critical separator or guide plate within the clutch pack assembly, ensuring correct oil flow and component alignment during gear engagement. The SKU 2094.311.079 is manufactured to exact ZF tolerances, providing a direct replacement that maintains factory-specified clearances. This sheet sits adjacent to the 2094101012: TRANSMISSION HOUSING and works in concert with the 2094301036: HOUSING to contain hydraulic pressure within the rotating drum assembly.
Symptoms of Failure
When the ZF 2094.311.079 sheet wears or deforms, operators may notice specific performance degradation. Oil starvation in forward gears occurs when the sheet warps, restricting fluid passages to the clutch packs. Delayed engagement or clutch shudder during low-speed maneuvering indicates the sheet is no longer maintaining proper separation between rotating elements. Metallic debris in the transmission oil filter suggests the sheet has fractured, releasing fragments into the hydraulic circuit. Intermittent gear slippage under load often points to this sheet failing to maintain correct piston travel limits. These symptoms are common search queries for technicians diagnosing ZF transmission issues.
