ZF 0501.325.472 LIFTING ARM | OEM Genuine Part

Overview

The ZF 0501.325.472 LIFTING ARM is a critical mechanical actuator within the final drive assembly of heavy-duty construction machinery. This OEM genuine part functions as the primary interface between the transmission housing and the shift mechanism, translating linear motion into the precise angular displacement required for gear selection. Machined from high-tensile forged steel, the SKU 0501.325.472 is engineered to withstand the cyclic torsional loads and vibrational stress inherent in excavator and wheel loader operations. It mounts directly onto the 2094101018: TRANSMISSION HOUSING, where its pivot bore interfaces with the shift rail system to ensure positive engagement under load.

Symptoms of Failure

• Erratic gear engagement or “gear hunting” under load: When the lifting arm’s pivot bore wears beyond tolerance, the shift fork cannot achieve full travel, causing intermittent disengagement during high-torque operations.
• Metallic clunking from the transmission bell housing: A worn lifting arm develops radial play at the pin joint, producing a distinct “clunk” during directional changes—a common search query for ZF WG-series operators.
• Oil seepage around the shift shaft seal area: Excessive lateral movement of a fatigued lifting arm distorts the adjacent 2094301069: HOUSING, compromising the shaft seal’s contact surface and leading to chronic fluid loss.
• Increased shift effort or lever stiffness: Corrosion or fretting on the arm’s contact pad creates friction that translates to operator fatigue and premature wear of the 2094298054: HOUSING guide channels.

Technical Specifications

Compatibility

This lifting arm is primarily specified for ZF WG180 and WG200 series powershift transmissions found in mid-size construction loaders and graders. It also fits select WG150 and WG310 variants where the shift mechanism uses a single-arm pivot geometry. The part interfaces directly with the 2094301071: COVER assembly that seals the shift chamber. For precise fitment verification, always cross-reference your transmission’s serial number against the ZF parts catalog.
