Overview
This OEM genuine ZF 4656.183.247 LOOSE PARTS kit is a critical service component designed specifically for the WG 171 Series transmission. It functions as a collection of essential fasteners, seals, and small hardware elements that secure and seal the transmission housing assembly. Positioned within the main casing of the gearbox, this kit ensures that the TRANSMISSION HOUSING remains properly aligned and leak-free under high-torque conditions. The SKU 4656.183.247 is a factory-original loose parts set, meaning it replaces all the small but vital components that degrade over time, preventing premature wear on larger assemblies.
Symptoms of Failure
When the ZF 4656.183.247 LOOSE PARTS begin to fail, operators often notice external oil seepage around the housing joints, particularly near the HOUS.FRONT SECT interface. A second common symptom is intermittent gear engagement hesitation caused by loose fasteners allowing micro-movement of internal components. Third, you may detect abnormal metallic rattling during low-speed operation, indicating that the SCREEN SHEET or internal TUBE has shifted from its original position. Finally, fluid contamination can occur if loose debris from worn fasteners enters the oil circuit, accelerating damage to clutches and bearings.

Compatibility
While the 4656.183.247 is factory-specified for the WG 171 Series, its loose parts configuration is also compatible with several adjacent ZF models. This kit fits the WG 180 and WG 200 transmissions, as well as the earlier WG 160 series, provided the housing architecture matches. For the WG 171 specifically, it works in tandem with the HOUSING REAR PART and requires the O-RING for proper sealing. Always verify your transmission’s serial number before ordering.

Frequently Asked Questions
Q: Can I reuse the old fasteners from my ZF WG171 instead of buying the 4656.183.247 kit?
A: It is not recommended. The loose parts kit includes new cap screws and O-rings that have been torque-rated for the housing. Reusing old hardware can lead to uneven clamping force and eventual oil leaks around the HOUS.FRONT SECT.
Q: Does this kit include the screen sheet or tube?
A: No. The 4656.183.247 covers only loose hardware such as bolts, pins, and seals. The SCREEN SHEET and TUBE are separate line items that must be ordered individually.
Q: How do I know if my transmission uses this specific loose parts set?
A: Check the transmission data plate for the WG 171 model designation. If the serial number falls within the 4656.xxx range, this kit is the correct match. For other series like WG180 or WG200, verify the housing bolt pattern matches the CAP SCREW dimensions listed in the specifications.
