Overview
This genuine OEM ZF 4656.183.132 LOOSE PARTS kit is a critical service component designed 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. Without this kit, the structural integrity of the gearbox is compromised, leading to fluid migration and mechanical instability. The SKU 4656.183.132 is engineered to match factory tolerances, ensuring a precise fit when paired with the TRANSMISSION HOUSING and the HOUS.FRONT SECT. This loose parts set is indispensable during a full rebuild or when addressing oil seepage at the casing joints.
Symptoms of Failure
- Transmission fluid seepage at housing seams: When the loose parts degrade, the seal between the HOUS.FRONT SECT and the main casing fails, causing visible oil drips.
- Loose or rattling transmission casing: Worn fasteners within the 4656.183.132 kit allow the TRANSMISSION HOUSING to vibrate excessively, producing a metallic rattle during gear shifts.
- Contaminated transmission fluid: A compromised seal from this kit permits debris to enter through the SCREEN SHEET area, leading to sludge buildup and erratic shifting.
- Intermittent gear engagement: Loss of clamping force from the loose parts can misalign the TUBE assembly, causing delayed or harsh engagement.

Compatibility
This 4656.183.132 LOOSE PARTS kit is specifically validated for the ZF WG 171 series. It is also mechanically compatible with the WG 180 and WG 200 series transmissions due to shared housing bolt patterns and seal groove dimensions. For installations involving the HOUSING REAR PART, this kit provides the necessary hardware to maintain structural rigidity. Always verify the condition of the CYLINDRICAL PIN alignment before final torque.

Frequently Asked Questions
Q: Can I reuse the old fasteners from my WG171 instead of buying this 4656.183.132 kit?
A: Reusing original fasteners is not recommended. The loose parts in this kit include pre-applied thread locker and precision seals that prevent fluid bypass. Old bolts may have stretched threads, leading to torque loss and eventual leaks.
Q: Does this kit include the O-ring for the TUBE connection?
A: Yes, the 4656.183.132 set contains the necessary O-RING (0634313514) and the CAP SCREW (0636100803) for securing the tube assembly. However, the TUBE itself is ordered separately.
Q: Is this part compatible with the ZF WG200 if I also replace the rear housing?
A: Compatibility is high, but you must also order the HOUSING REAR PART (4656301042) and the CYLINDRICAL PIN (0631306816) to ensure correct alignment on the WG200 bell housing.
