Overview
The ZF 4657.183.234 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 210 series transmission. This genuine OEM part set contains the necessary loose hardware and small components required to secure and seal the main structural elements of the gearbox during a rebuild or overhaul. Positioned at the interface between the transmission housing and the front/rear sections, this kit ensures proper clamping force and alignment of the drivetrain. The SKU 4657.183.234 is the exact factory-specified collection of fasteners and fittings, eliminating the guesswork of sourcing individual pieces. Without this kit, the integrity of the entire transmission assembly is compromised, leading to potential misalignment of the TRANSMISSION HOUSING and the HOUS.FRONT SECT.
Symptoms of Failure
When the components within the ZF 4657.183.234 LOOSE PARTS kit begin to fatigue or are missing, several distinct operational issues will manifest. Recognizing these “ZF WG210 loose parts failure symptoms” early can prevent catastrophic damage.
- Transmission oil seepage at housing joints: Worn or missing bolts and pins from this kit cause the HOUSING REAR PART to lose its seal, resulting in visible oil leaks around the mating flanges.
- Abnormal gear engagement noise: Loose fixing plates or cap screws allow the internal shafts to shift slightly, producing a distinct clunking or grinding sound during gear changes.
- Vibration under load: A failure of the cylindrical pins or screen sheets leads to instability in the rear section, causing noticeable driveline vibration when the vehicle is under torque.
- Intermittent gear slippage: If the HOUSING REAR SECTION is not properly secured by the loose parts, the clutch packs may not receive consistent hydraulic pressure, leading to slipping.

Frequently Asked Questions
Q: Can I reuse the old bolts and pins from my existing transmission instead of buying this kit?
A: No. ZF specifies that these fasteners are single-use due to torque-to-yield requirements. Reusing them can lead to improper clamping force, resulting in oil leaks and potential failure of the TRANSMISSION HOUSING seal.
Q: Does this kit include the cap screws for the rear section?
A: Yes, the 4657.183.234 LOOSE PARTS kit contains the necessary cap screws and cylindrical pins. For specific high-torque applications, you may also need the 0636100803 CAP SCREW separately.
Q: Is this part compatible with the ZF WG180 model?
A: Yes. The kit is designed for the WG210 series but is fully compatible with the WG180 and WG200 models, as they share the same housing bolt pattern and pin dimensions.
