Overview
The ZF 4657.183.191 LOOSE PARTS for WG210 is a critical service kit designed to restore the internal sealing and alignment integrity of your ZF WG210 series transmission. This OEM genuine part set includes the specific gaskets, seals, and small hardware necessary to prevent fluid migration between the main housing sections. The SKU 4657.183.191 is typically deployed during a major overhaul when the transmission is removed from the vehicle, ensuring that the interface between the TRANSMISSION HOUSING and the HOUS.FRONT SECT remains leak-free under high hydraulic pressure. Without this loose parts package, even a perfectly machined housing assembly will suffer from premature fluid loss and contamination.
Symptoms of Failure
When the components within the 4657.183.191 kit degrade, operators will notice distinct performance issues. The most common symptom is external oil seepage at the housing split lines, often visible as a slow drip after the vehicle has been parked overnight. A second critical sign is erratic gear engagement or delayed shifting, caused by internal pressure loss between the HOUSING REAR PART and the main body. Third, you may experience low transmission fluid levels without visible external leaks, indicating internal cross-leakage. Finally, contaminated fluid with metallic particles can appear as the loose parts wear and allow debris to bypass the filtration system.

Frequently Asked Questions
Q: Can I reuse the old gaskets from my WG210 instead of buying the 4657.183.191 kit?
A: No. ZF explicitly recommends replacing all loose parts and seals during any housing disassembly. Reusing old gaskets will almost certainly lead to immediate fluid leaks and potential transmission damage.
Q: Does this kit include the cap screws for the housing?
A: The 4657.183.191 kit contains only the loose sealing elements and small hardware. For the required fasteners, you will need to order 0636100801: CAP SCREW or 0636100803: CAP SCREW separately.
Q: How do I know if my transmission uses the WG210 housing variant?
A: Check the stamped serial number on the main TRANSMISSION HOUSING. If it begins with “WG210” or “WG180,” this kit is the correct match.
