Overview
This OEM genuine ZF 4657.183.247 LOOSE PARTS set is a critical service kit designed specifically for the WG 211 series transmission. It contains the precise internal components required to restore the shifting assembly and hydraulic circuit integrity within the gearbox. The SKU 4657.183.247 is typically installed during a major overhaul to replace worn fasteners, seals, and locating elements that degrade over time. This part works in direct conjunction with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to ensure proper alignment and oil flow within the main casing.
Symptoms of Failure
- Erratic gear engagement and delayed shifting: When the loose parts in this kit wear out, you may experience hesitation or harsh engagement between forward and reverse gears, particularly under load.
- Internal oil leaks and pressure loss: Degraded seals and loose fasteners cause transmission fluid to bypass critical circuits, leading to low line pressure and eventual overheating.
- Abnormal vibration or rattling from the bell housing: Worn cylindrical pins or loose mounting hardware allow the HOUSING REAR PART to shift, creating metallic noise during operation.
- Inability to hold torque on steep grades: A failing loose parts set compromises the clamping force on clutch packs, resulting in transmission slippage under heavy load.

Frequently Asked Questions
Q: Can the ZF 4657.183.247 LOOSE PARTS kit be reused after disassembly?
A: No. This kit contains single-use fasteners, seals, and locking elements. Reusing them risks oil leaks and fastener loosening under vibration. Always install a new OEM genuine kit during any WG211 rebuild.
Q: Does this part include the CYLINDRICAL PIN (0631306816)?
A: The 4657.183.247 kit does not include the alignment pin. You must order the CYLINDRICAL PIN separately if your housing alignment dowels are worn or damaged.
Q: What is the typical service interval for replacing this loose parts set?
A: ZF recommends replacing this kit every 500,000 km or during any major transmission overhaul. Symptoms like delayed engagement or oil seepage around the HOUS.FRONT SECT indicate immediate replacement is needed.
