Overview
The ZF 4657.183.282 LOOSE PARTS kit is a critical OEM service set designed specifically for the WG 210 series transmission. This assembly contains the necessary fasteners, seals, and positioning components that secure the main housing sections together, ensuring precise alignment of internal shafts and gear clusters. The SKU 4657.183.282 is a genuine ZF loose parts package that replaces all worn or missing hardware during a major overhaul, preventing axial play and maintaining hydraulic pressure integrity within the gearbox.
Symptoms of Failure
- Transmission oil leaks at housing mating surfaces – When the loose parts (bolts, pins, or plates) lose torque or corrode, oil seeps between the front and rear housing sections, leaving puddles under the vehicle.
- Gear slipping under load – Worn fixing plates or cap screws allow the housing halves to shift slightly, misaligning clutch packs and causing intermittent power loss during acceleration.
- Abnormal vibration or driveline noise – Loose housing connections permit micro-movement of the TRANSMISSION HOUSING, which transmits harsh harmonics through the drivetrain at highway speeds.
- Difficult gear engagement – A compromised rear housing section can distort the valve body mounting surface, leading to delayed or harsh shifts from park to drive.

Compatibility
This loose parts kit is engineered for the ZF WG 210 series, but it also fits select models in the WG180, WG200, and WG250 families where housing bolt patterns are shared. It is commonly used during rebuilds of the HOUS.FRONT SECT and HOUSING REAR PART assemblies. For complete housing replacement, pair this kit with the HOUSING REAR SECTION to ensure all mating surfaces are properly secured. Always verify your transmission serial number before ordering.
