Overview
The ZF 4657.183.152 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 series transmission. This genuine OEM assembly contains the essential fasteners, seals, and positioning elements required to secure internal sub-assemblies during a rebuild or overhaul. Positioned within the main gear train housing, this kit ensures that the TRANSMISSION HOUSING maintains proper alignment with the HOUS.FRONT SECT and the HOUSING REAR PART. The SKU 4657.183.152 is factory-matched to prevent vibration loosening and oil bypass, making it indispensable for any technician performing a full transmission restoration.
Symptoms of Failure
When the loose parts in this kit degrade or are improperly torqued, operators will notice distinct performance issues. Look for these specific failure indicators:
- Transmission oil weeping from housing seams – Worn or missing fasteners allow the CYLINDRICAL PIN to shift, breaking the seal between the front and rear sections.
- Gear engagement hesitation under load – Loose mounting points cause micro-movement in the valve body, delaying clutch pack activation.
- Metallic rattling at low RPM – Unsecured internal components vibrate against the housing walls, indicating that the LOOSE PARTS have lost their clamping force.
- Intermittent loss of hydraulic pressure – A compromised seal between the oil feed housing and the main case leads to erratic shift quality.

Compatibility
This LOOSE PARTS kit is engineered for the WG 210 series but shares mounting patterns with several other ZF transmissions. It is directly compatible with the WG180, WG200, and WG250 models when used in conjunction with the correct FIXING PLATE. The kit also fits the WG 211 and WG 212 variants that utilize the same housing architecture. Always verify your transmission serial number before ordering, as the SCREEN SHEET (4657301032) and SCREEN SHEET (4657301033) may require separate replacement depending on your specific build date.
