ZF 4657.183.324 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.324 LOOSE PARTS for WG210 is a critical OEM genuine component designed for the internal assembly of ZF WG series transmissions. This part functions as a specialized fastener or spacer kit, ensuring precise alignment and secure retention of internal gear clusters and shaft assemblies within the transmission housing. The SKU 4657.183.324 is specifically engineered to maintain the tight tolerances required for smooth power flow and hydraulic pressure regulation in the WG210 gearbox. When installed correctly, this loose parts set prevents axial movement of rotating elements, directly contributing to the transmission’s overall durability and shift quality.

Symptoms of Failure

• Transmission oil leaks from the housing joint: When the 4657.183.324 components degrade, they can no longer maintain a proper seal between the TRANSMISSION HOUSING and the HOUS.FRONT SECT, leading to visible fluid seepage.
• Gear slipping under load: Worn or missing loose parts cause internal clearances to increase, resulting in intermittent gear engagement and a loss of torque transfer during acceleration.
• Abnormal rattling or knocking noises: As the HOUSING REAR PART loses its secure fit, metallic contact between gears produces a distinct rattling sound during deceleration.
• Erratic shift timing: Hydraulic pressure fluctuations occur when the HOUSING REAR SECTION shifts out of alignment, causing delayed or harsh gear changes.

Technical Specifications

Compatibility

This OEM genuine part is primarily designed for the ZF WG210 series, but it also fits select models in the WG180, WG200, and WG220 families due to shared internal architecture. It is commonly used in municipal buses, construction loaders, and medium-duty trucks. Always verify the part number against your transmission’s serial plate. For proper installation, ensure the CYLINDRICAL PIN and CAP SCREW are replaced simultaneously to guarantee correct torque specifications.
