ZF 4657.183.297 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.297 LOOSE PARTS kit is a critical service component designed specifically for the WG 210 series transmission. This genuine OEM assembly contains the essential loose hardware and fasteners required to secure and align the main transmission housing sections during rebuild or repair. Positioned at the interface between the front and rear housing assemblies, this kit ensures proper clamping force and structural integrity of the gearbox casing. The SKU 4657.183.297 is factory-matched to the WG210 platform, guaranteeing that every bolt, pin, and plate meets ZF’s original torque and material specifications.

Symptoms of Failure

When the 4657.183.297 loose parts become worn or are not replaced during a transmission overhaul, several distinct failure modes emerge. Oil seepage at the housing joint is the most common indicator, as degraded fasteners lose their ability to maintain a uniform seal. Abnormal gear slippage under load often follows, caused by micro-movement between the housing sections that misaligns the planetary gear sets. Persistent metallic rattling from the bell housing area signals that the fixing plates or cap screws have loosened, allowing internal components to shift. Finally, intermittent loss of hydraulic pressure can occur when the housing flexes, disrupting the valve body alignment.

Technical Specifications

Compatibility

This genuine ZF loose parts kit is engineered primarily for the WG 210 series transmissions. Based on the hardware configuration, it is also compatible with the WG 180 and WG 200 series models that share the same housing bolt pattern and pin alignment. The kit integrates directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to establish a secure foundation. It also works in tandem with the HOUSING REAR PART and the HOUSING REAR SECTION to complete the full casing assembly. Always verify your transmission model’s serial number before ordering.

Frequently Asked Questions

Q: Can the 4657.183.297 kit be reused if I only replace one housing section?
No. ZF recommends always installing a new loose parts kit whenever the housing is separated. The fasteners are torque-to-yield and lose their clamping force after initial installation, which can lead to oil leaks or gear misalignment if reused.

Q: Does this kit include the screen sheets or do I need to order them separately?
The 4657.183.297 LOOSE PARTS kit includes the cap screws, cylindrical pins, and fixing plates, but the screen sheets (part numbers 4657301032 and 4657301033) are separate items. We recommend ordering them together to ensure all filtration components are renewed during the rebuild.

Q: How do I confirm this kit fits my WG210 transmission?
Check the transmission serial number plate located on the main housing. The WG210 series will have “WG210” stamped on the tag. If your transmission is a WG180 or WG200 variant, verify the bolt pattern matches the dimensions listed in the technical specifications above.
