ZF 4657.183.084 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.084 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 210 Series transmission. This genuine OEM part contains the necessary fasteners, seals, and positioning components required to secure the main transmission housing sections during rebuild or repair. The SKU 4657.183.084 is typically installed during a full overhaul to ensure that the TRANSMISSION HOUSING maintains proper alignment with the HOUS.FRONT SECT and the HOUSING REAR PART. Without this loose parts set, the structural integrity of the gear train assembly is compromised.

Symptoms of Failure

When the ZF 4657.183.084 LOOSE PARTS begin to fail or are missing during reassembly, operators typically encounter these specific failure modes:

• Transmission oil weeping at mating flanges – A common sign that the fasteners from the loose parts kit have loosened, allowing fluid to escape between the housing sections.
• Abnormal gear rattle or whine under load – This occurs when the CYLINDRICAL PIN (included in the kit) wears or shifts, causing misalignment of the internal shafts.
• Intermittent gear slipping in higher ranges – A worn or missing fixing plate from the kit can allow the clutch housing to shift slightly, leading to pressure loss.
• Vibration during torque converter lockup – Loose cap screws in the assembly can create harmonic imbalance, felt through the driveline.

Technical Specifications

Compatibility

This genuine ZF 4657.183.084 LOOSE PARTS kit is engineered for the WG 210 Series transmission family. Based on the part type and housing geometry, it is also compatible with the following ZF models: WG180, WG200, and WG210. It is not recommended for use in the WG120 or WG150 series due to different bolt patterns and housing depths. Always verify that the TRANSMISSION HOUSING casting number matches your unit before installation.

Frequently Asked Questions

Q: Can I reuse the old fasteners from my WG210 instead of buying the 4657.183.084 kit?
A: ZF strongly discourages reusing cap screws or cylindrical pins from the original assembly. The 4657.183.084 LOOSE PARTS kit includes new, torqued-to-spec fasteners that prevent stress fractures and oil leaks. Reusing old hardware often leads to the failure symptoms described above.

Q: Does this kit include the screen sheets or do I need to order them separately?
A: The 4657.183.084 kit contains the primary fasteners and the cylindrical pin. The screen sheets (part numbers 4657301032 and 4657301033) are separate components that should be replaced concurrently for optimal filtration.

Q: Will this part fit a ZF WG180 transmission built before 2005?
A: Yes, the 4657.183.084 LOOSE PARTS kit is backward-compatible with WG180 and WG200 units that share the same housing bolt pattern as the WG210. However, you must verify that your HOUSING REAR PART casting number matches the OEM specification for the kit to seat correctly.
