Overview
The ZF 4657.183.305 LOOSE PARTS kit is a critical service component designed specifically for the WG 211 Series transmission. This genuine OEM assembly contains the necessary loose hardware and small components required to properly secure and align internal transmission sections during a rebuild or major repair. The SKU 4657.183.305 typically includes fasteners, locating pins, and sealing elements that ensure the TRANSMISSION HOUSING maintains structural integrity under heavy load. Without this specific parts set, reassembly of the WG211 gearbox is incomplete, risking misalignment and premature wear.
Symptoms of Failure
- Transmission oil seepage at housing joints: When the 4657.183.305 loose parts degrade or are missing, the seal between the HOUS.FRONT SECT and the main casing fails, leading to visible oil weeping.
- Gear slipping under moderate torque: Worn locating pins or bolts from this kit allow the HOUSING REAR PART to shift slightly, causing intermittent gear disengagement.
- Abnormal vibration during shifting: Loose hardware creates micro-movements between transmission sections, producing a distinct shudder when changing gears.
- Difficulty in transmission reassembly: A missing CYLINDRICAL PIN from the kit prevents proper alignment, making installation of the housing components impossible without force.

Frequently Asked Questions
Q: Can I reuse the original bolts instead of buying the 4657.183.305 kit?
A: It is not recommended. ZF specifies that these loose parts, including cap screws and cylindrical pins, should be replaced during any major service to prevent fatigue failure and ensure proper torque retention.
Q: Does this kit include the CYLINDRICAL PIN (0631306816)?
A: Yes, the 4657.183.305 LOOSE PARTS set typically includes the alignment pins, though we recommend checking the kit contents against your specific transmission variant. The CYLINDRICAL PIN is a critical component for aligning the housing sections.
Q: Will this part work on a WG180 transmission?
A: The 4657.183.305 is designed for the WG211 series, but it shares fastener specifications with the WG180 and WG200 models. Verify your housing part numbers, especially the HOUS.FRONT SECT and HOUSING REAR PART, to confirm cross-compatibility.
