Overview
The ZF 4657.183.292 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 series transmission. This genuine OEM assembly contains the necessary fasteners, seals, and positioning elements required to secure and align the main structural casings of the gearbox. When rebuilding or servicing a WG210 unit, this kit ensures that the TRANSMISSION HOUSING maintains proper clamping force and dimensional stability. The SKU 4657.183.292 sits at the interface between the front and rear sections, acting as the final lock for the entire assembly.
Symptoms of Failure
- Transmission oil seepage at the housing split line: When the loose parts in this kit fatigue, the clamping force between the HOUS.FRONT SECT and the rear casing diminishes, leading to visible fluid weeping.
- Abnormal gear engagement noise under load: Worn or missing fasteners from the 4657.183.292 set allow micro-movement between the HOUSING REAR PART and the main body, causing misalignment and audible grinding.
- Intermittent gear slipping in higher ranges: Loss of structural rigidity from degraded loose parts can shift the HOUSING REAR SECTION out of tolerance, resulting in clutch pack slippage.
- Vibration through the driveline during acceleration: A compromised fastening system allows the entire housing assembly to flex, transmitting harsh harmonics into the output shaft.

Frequently Asked Questions
Q: Can the 4657.183.292 kit be reused after a transmission rebuild?
A: No. ZF specifies that all loose parts in this kit, including the cap screws and cylindrical pins, must be replaced with new OEM components during any major housing disassembly to guarantee proper torque retention and prevent oil leaks.
Q: Does this kit include the gaskets for the housing split line?
A: The 4657.183.292 LOOSE PARTS kit contains only the fasteners and positioning hardware. Separate gasket sets (such as the screen sheets 4657301032 and 4657301033) are required for complete sealing.
Q: How do I verify if this part fits my WG210 transmission?
A: Check the serial number plate on the TRANSMISSION HOUSING. If the model designation includes WG210, WG180, WG200, or WG250, this kit is the correct OEM replacement.
