ZF 4657.183.296 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.296 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 internal transmission sections during a rebuild or major repair. The SKU 4657.183.296 functions as a consolidation point for small hardware that is often lost or damaged during disassembly, ensuring proper clamping force and alignment between the main housing sections. Without this loose parts set, the structural integrity of the gear train and hydraulic circuits cannot be guaranteed, making it an essential purchase for any WG210 overhaul.

Symptoms of Failure

When the components within the 4657.183.296 kit wear out or are missing, operators typically encounter external oil seepage at the transmission case split lines, a common long-tail search query for WG210 leaks. Another frequent failure symptom is intermittent gear slippage under load, caused by insufficient bolt tension allowing housing flex. Technicians also report abnormal vibration or driveline noise during acceleration, which often traces back to loose fasteners that allow the TRANSMISSION HOUSING to shift slightly. Finally, erratic shift timing or delayed engagement can occur if the loose parts fail to maintain precise alignment of the valve body mounting points.

Technical Specifications

Compatibility

This genuine ZF loose parts kit is engineered primarily for the WG 210 Series transmission. Based on the part type and OEM numbering, it is also compatible with the WG180 and WG200 models that share the same housing architecture. The kit interfaces directly with the HOUS.FRONT SECT and the HOUSING REAR PART, as well as the HOUSING REAR SECTION. Always verify your transmission serial number before ordering to ensure correct fitment.

Frequently Asked Questions

Q: Can I reuse the old fasteners from my WG210 instead of buying the 4657.183.296 kit?
A: ZF strongly discourages reusing bolts and pins from the loose parts kit. These fasteners are designed for single-use torque-to-yield applications. Reusing them can lead to improper clamping force, resulting in oil leaks or internal misalignment.

Q: Does this kit include the cap screws and screen sheets listed in the related components table?
A: No. The 4657.183.296 LOOSE PARTS kit contains only the specific hardware designated for that assembly. The cap screws (0636100801, 0636100803) and screen sheets (4657301032, 4657301033) are separate line items that must be ordered individually if needed for your rebuild.

Q: How do I confirm this part fits my specific ZF transmission?
A: Cross-reference your transmission model number (e.g., WG210, WG180, WG200) with the OEM part number 4657.183.296. For exact fitment, consult the ZF parts catalog or contact a certified ZF service center with your transmission serial number.
