ZF 4657.201.173 HOUSING REAR PART for WG210 | OEM Genuine Part

Overview

The ZF 4657.201.173 HOUSING REAR PART is a critical structural component designed for the WG210 series of ZF industrial transmissions. This rear housing section encloses the output shaft assembly and provides the mounting interface for the transmission’s rear bearing support and oil sealing system. As an OEM genuine part, SKU 4657.201.173 ensures precise alignment and load distribution within the gear train, directly influencing torque transfer and overall driveline stability. When installed alongside the 4657101083: TRANSMISSION HOUSING and the 4657201166: HOUS.FRONT SECT, this rear housing completes the main structural envelope of the WG210 transmission.

Symptoms of Failure

• Persistent rear oil leaks: A cracked or warped housing rear part often causes fluid seepage around the output shaft seal, leading to low transmission fluid levels and potential overheating.
• Abnormal driveline vibration: Wear or distortion in the housing rear section can misalign the output bearing, producing noticeable vibration during gear engagement or under load.
• Gear engagement difficulty or slipping: If the housing rear part loses its dimensional integrity, the shift linkage or clutch pack alignment may be compromised, resulting in delayed or incomplete gear shifts.
• Metallic debris in oil pan: Internal cracking of the housing can release aluminum or steel fragments into the lubrication circuit, accelerating wear on bearings and gears.

Technical Specifications

Compatibility

This rear housing part is primarily engineered for the ZF WG210 series. Based on its design and mounting geometry, it is also compatible with the following ZF transmission models: WG180, WG200, WG210, and WG250 (with minor adapter modifications). For proper installation, always pair this housing with the 0631306816: CYLINDRICAL PIN for alignment and secure it using the 0636100801: CAP SCREW to ensure correct clamping force.
