Overview
This genuine OEM ZF 4657.183.006 LOOSE PARTS kit is an essential service component for the WG 190 transmission series. It contains the specific loose hardware and small fittings required to secure and align internal assemblies within the gearbox. The SKU 4657.183.006 is designed to replace worn or damaged fasteners and spacers that can compromise the structural integrity of the transmission. This kit works in conjunction with the 4657101031: TRANSMISSION HOUSING to ensure that all internal components remain precisely positioned under high torque loads.
Symptoms of Failure
When the components in this LOOSE PARTS kit degrade, operators may notice specific operational issues. Transmission housing misalignment often occurs when the fasteners lose their clamping force, leading to uneven gear wear. Oil seepage at the housing joint is another common symptom, as loose hardware cannot maintain a proper seal between the 4657201027: HOUS.FRONT SECT and the main casing. Intermittent gear engagement or a clattering noise during shifting can indicate that the internal locating pins have loosened. Finally, vibration at the bell housing during acceleration suggests that the rear mounting points, including those secured by the 4657201020: HOUSING REAR PART, have lost their original tolerance.

Compatibility
This genuine ZF 4657.183.006 kit is primarily engineered for the WG 190 series transmissions. It is also compatible with the WG 180 and WG 200 models that share the same modular housing architecture. The kit is specifically designed to interface with the 4657101031: TRANSMISSION HOUSING and the 4657201027: HOUS.FRONT SECT. It is not intended for use in the WG 210 series without verifying the bolt pattern against the 4657201020: HOUSING REAR PART dimensions.

Frequently Asked Questions
Q: Can I reuse the old hardware from my WG190 instead of buying the 4657.183.006 kit?
A: ZF strongly discourages reusing fasteners from this LOOSE PARTS kit. The bolts and pins are torque-to-yield components that lose their clamping force after initial installation. Using new parts ensures proper preload on the 4657101031: TRANSMISSION HOUSING.
Q: Does this kit include the CYLINDRICAL PIN for alignment?
A: No, the 4657.183.006 kit contains the loose fasteners and spacers only. The alignment pin must be ordered separately as 0631306792: CYLINDRICAL PIN to ensure proper dowel fitment between the front and rear housing sections.
Q: How do I know if my WG190 needs this LOOSE PARTS kit?
A: If you are rebuilding the transmission or replacing the 4657201020: HOUSING REAR PART, you should always install a fresh 4657.183.006 kit. Visual signs of wear include stripped threads on the cap screws or corrosion on the fixing plate.
