ZF 4657.354.069 PUMP SHAFT for WG210 | OEM Genuine Part

Overview

The ZF 4657.354.069 PUMP SHAFT is a critical rotating component engineered specifically for the WG 210 Series transmission. This OEM genuine part transmits torque directly from the transmission’s hydraulic pump to the gear train, ensuring consistent oil flow and pressure regulation throughout the drivetrain. Positioned within the pump housing assembly, the shaft interfaces with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain precise alignment. The SKU 4657.354.069 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged shafts in heavy-duty industrial applications.

Symptoms of Failure

• Erratic hydraulic pressure and gear slipping: A worn pump shaft causes irregular pump rotation, leading to inconsistent clutch engagement and transmission slippage under load.
• Oil leaks near the pump housing: Excessive shaft play damages the SURFACE SEALING COMPOUND and adjacent seals, resulting in visible fluid seepage around the front or rear housing joints.
• Metallic grinding or whining noise: Bearing surface degradation on the shaft produces audible high-pitched sounds during acceleration or deceleration, indicating imminent failure.
• Delayed engagement or harsh shifting: Reduced pump output due to shaft wear causes slow pressure buildup, leading to jarring gear changes or hesitation when moving from neutral to drive.

Technical Specifications

Compatibility

This pump shaft is primarily designed for the ZF WG 210 Series, but it also fits select models in the WG180, WG200, and WG250 families when used with the correct HOUSING REAR PART. Always verify housing compatibility: the shaft requires precise alignment with the pump bore in the TRANSMISSION HOUSING and the HOUS.FRONT SECT. For mixed-series assemblies, confirm that the SURFACE SEALING COMPOUND is reapplied during installation to prevent leaks.
