Overview
This genuine OEM ZF 4657.199.041 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 Series transmission. It functions as a collection of essential fasteners, seals, and positioning elements that secure internal assemblies within the gearbox housing. Without this kit, the structural integrity of the clutch and planetary gear sets is compromised. The SKU 4657.199.041 is the factory-authorized replacement for maintaining precise alignment between the TRANSMISSION HOUSING and the HOUS.FRONT SECT, ensuring no axial play develops during high-torque operation.
Symptoms of Failure
When the 4657.199.041 LOOSE PARTS begin to degrade, operators often notice intermittent gear slipping under load due to fastener loosening. A second common failure is oil weeping from the housing split line, which occurs when the included seals lose elasticity. Third, you may detect abnormal metallic rattling during deceleration, indicating that the HOUSING REAR PART has shifted out of tolerance. Finally, hard shifting between 2nd and 3rd gear can occur if the CYLINDRICAL PIN shears, misaligning the valve body.

Compatibility
This LOOSE PARTS kit is engineered for the ZF WG 210 Series, but it also cross-fits the WG 180 and WG 200 models due to shared housing architecture. It is not compatible with the Ecomat 4HP or 5HP series. The kit directly interfaces with the TRANSMISSION HOUSING and the HOUS.FRONT SECT, making it essential for any rebuild of the WG210 family. Always verify your transmission serial number against the ZF parts catalog before ordering.

Frequently Asked Questions
Q: Can I reuse the old fasteners from my WG210 instead of buying this LOOSE PARTS kit?
A: No. ZF specifies that all bolts and pins in the 4657.199.041 kit are single-use torque-to-yield fasteners. Reusing them risks thread galling and housing misalignment.
Q: Does this kit include the gasket for the HOUSING REAR PART?
A: Yes. The 4657.199.041 LOOSE PARTS set contains the necessary sealing washers and the O-ring for the HOUSING REAR PART interface. A separate gasket is not required.
Q: How do I verify this part fits my specific WG210 variant?
A: Check the casting number on your TRANSMISSION HOUSING. If it ends with “1033”, this kit is compatible. For earlier variants, consult our compatibility table above.
