Overview
This OEM genuine ZF 4656.183.380 LOOSE PARTS kit is a critical service set for the WG 171 series transmission. It contains the specific fasteners, seals, and small hardware required to secure and seal the main transmission housing assembly. The SKU 4656.183.380 is designed to replace worn or damaged loose components that can compromise the structural integrity of the gearbox. This kit directly interfaces with the TRANSMISSION HOUSING and the HOUS.FRONT SECT, ensuring that all mounting points and fluid passages remain properly aligned and leak-free.
Symptoms of Failure
When the loose parts in the ZF 4656.183.380 kit begin to fail, operators often notice specific performance issues. Look for these common failure symptoms:
- External oil leaks at housing seams: Worn or missing fasteners cause the HOUS.FRONT SECT to separate from the main body, leading to fluid seepage.
- Gear slippage under load: Loose mounting hardware allows the transmission housing to flex, disrupting gear alignment and causing intermittent power loss.
- Abnormal vibration or driveline noise: Degraded hardware fails to dampen resonance between the TRANSMISSION HOUSING and the bell housing, producing a distinct rattle during acceleration.
- Contaminated transmission fluid: A compromised seal from a failed TUBE connection allows debris to enter the hydraulic circuit.

Frequently Asked Questions
Q: Can I reuse the old fasteners from my WG171 transmission instead of buying this kit?
A: No. ZF specifies that all bolts and seals in the 4656.183.380 kit are single-use items. Reusing them risks torque failure and fluid leaks, especially around the TRANSMISSION HOUSING.
Q: Does this kit include the O-rings for the TUBE connection?
A: Yes. The 4656.183.380 LOOSE PARTS kit contains the necessary O-rings and seals to properly install the TUBE and SCREEN SHEET.
Q: How do I verify this part fits my WG180 transmission?
A: Check your transmission serial number against the ZF parts catalog. The 4656.183.380 is a direct fit for WG171, WG180, and WG200 models with the standard housing configuration.
