ZF 4108.322.056 SWASH PLATE | OEM Genuine Part

Overview

The ZF 4108.322.056 SWASH PLATE is a precision-machined hydraulic control component situated within the pump housing of ZF powershift transmissions. This OEM genuine part modulates fluid flow to regulate clutch pack engagement, directly influencing torque distribution and machine responsiveness. As a critical element in the hydrostatic circuit, the swash plate interfaces with the piston assembly to convert rotational motion into hydraulic pressure. The SKU 4108.322.056 is manufactured to exacting OEM tolerances, ensuring seamless integration with your transmission’s control system. When paired with a properly sealed 4108101093: HOUSING, this component maintains the hydraulic integrity required for heavy-duty construction machinery operations.

Symptoms of Failure

• Erratic gear engagement or slipping under load: A worn swash plate surface reduces hydraulic pressure, causing delayed or incomplete clutch pack engagement during excavation or grading tasks.
• Hydraulic oil overheating: Internal leakage past a scored swash plate generates excessive heat, often accompanied by darkened or burnt-smelling transmission fluid.
• Unusual whining or knocking from transmission: Pitting or galling on the swash plate face creates metallic noise during pump operation, particularly at low RPM.
• Intermittent loss of forward/reverse drive: Degraded swash plate geometry leads to inconsistent stroke control, resulting in sudden power loss when maneuvering on inclines.

Technical Specifications

Compatibility

This swash plate is designed for ZF WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, dozers, and excavators. It also fits select ZF 4WG-200 and 6WG-200 variants used in construction machinery from 1998 onward. For proper installation, ensure the mating 4108201177: HOUSING is free of scoring and that the 0501313402: DRAIN VALVE is functioning to prevent pressure spikes. Always replace the 0636302056: SCREW PLUG during service to maintain thread integrity in the housing port.
