Overview
This genuine ZF 4657.183.263 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 series transmission. It contains the essential fasteners, seals, and small hardware required to secure and seal the main transmission housing assembly during rebuild or repair. The SKU 4657.183.263 is an OEM genuine part, ensuring exact fitment and factory-specified clamping forces. This kit sits at the interface between the main transmission housing and the front/rear sections, preventing fluid migration and maintaining structural integrity under high torque loads.
Symptoms of Failure
- External transmission fluid seepage at housing joints: When the loose parts in this kit (such as cap screws or sealing elements) degrade, you will notice oil weeping from the seam between the TRANSMISSION HOUSING and the HOUS.FRONT SECT.
- Abnormal gear engagement noise or vibration: Worn or missing fasteners allow micro-movement between the HOUSING REAR PART and the main case, leading to misalignment and harsh shifting.
- Contaminated transmission fluid: A compromised seal from degraded loose parts permits dirt ingress through the HOUSING REAR SECTION joint, causing premature wear on internal clutches.
- Torque converter housing leaks: Loose or corroded cap screws in this kit can cause fluid loss at the bell housing interface, often mistaken for a pump seal failure.

Frequently Asked Questions
Q: Can I reuse the old cap screws from my WG210 transmission instead of buying this kit?
A: No. ZF specifies that all fasteners in the 4657.183.263 LOOSE PARTS kit must be replaced during any housing disassembly. Reusing old screws risks thread galling and incorrect torque, leading to fluid leaks.
Q: Does this kit include the gaskets for the housing joints?
A: This specific SKU contains loose hardware (screws, pins, washers) but not full gaskets. For complete sealing, order the appropriate gasket set separately. The kit is designed to work with the TRANSMISSION HOUSING and its mating sections.
Q: How do I confirm this part fits my ZF WG180 transmission?
A: Check the serial number plate on your transmission. The 4657.183.263 is standard for WG180 through WG250 series. If your unit uses a different bolt pattern, compare the included CYLINDRICAL PIN diameter with your original hardware.
