ZF 4657.376.014 SHAFT for WG210 | OEM Genuine Part

Overview

The ZF 4657.376.014 SHAFT is a critical torque-transfer component engineered specifically for the WG210 series transmission. This OEM genuine part serves as the primary rotational axis within the gear train, ensuring precise alignment and smooth power delivery from the engine to the driveline. Manufactured to ZF’s exacting tolerances, the SKU 4657.376.014 interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain concentricity under heavy load. Without this shaft, the entire gearset loses its structural foundation, leading to catastrophic misalignment.

Symptoms of Failure

• Vibration during gear engagement: A worn 4657.376.014 shaft causes excessive radial play, resulting in noticeable shuddering when shifting from neutral to drive.
• Oil leaks near the front seal area: As the shaft surface wears, it damages the seal contact path, allowing transmission fluid to weep past the HOUSING REAR PART interface.
• Intermittent gear slipping under load: When the shaft splines degrade, torque transfer becomes inconsistent, causing the transmission to momentarily lose power during uphill climbs or heavy hauling.
• Metallic grinding noise from the bell housing: A fatigued shaft can contact the CYLINDRICAL PIN, producing a distinct scraping sound that worsens with RPM.

Technical Specifications

Compatibility

This shaft is a direct fit for the WG210 series and is also compatible with the WG180, WG200, and WG250 transmission families when used with the corresponding TRANSMISSION HOUSING variant. It is not backward-compatible with pre-2005 WG120 models due to differing spline pitch. Always verify the housing bore diameter before installation.
