Overview
The ZF 4657.199.049 LOOSE PARTS kit is a critical service assembly designed for the WG190 and WG210 series transmissions. This genuine OEM part set contains the specific fasteners, seals, and positioning components required to secure internal sub-assemblies within the main gear case. When performing a deep rebuild or replacing the TRANSMISSION HOUSING, this loose parts kit ensures that all hardware meets factory torque specifications. The SKU 4657.199.049 is frequently ordered alongside the HOUS.FRONT SECT to guarantee a complete seal between the front section and the main body.
Symptoms of Failure
- Transmission fluid seepage at housing joints: When the loose parts in this kit degrade, you may notice oil weeping from the mating surface between the HOUSING REAR PART and the main case, especially during high-load operation.
- Loose or rattling internal components: Worn fasteners from the 4657.199.049 set can cause a distinct metallic rattle from the transmission bell housing, indicating that the CYLINDRICAL PIN alignment is compromised.
- Intermittent gear engagement hesitation: If the retaining hardware fails, the valve body or clutch pack can shift slightly, leading to delayed engagement when shifting from neutral to drive.
- Increased vibration during torque conversion: A missing or damaged component from this kit can allow the front support to micro-move, transmitting vibration through the driveline.
