ZF 4657.183.086 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.086 LOOSE PARTS kit is a critical service component designed specifically for the WG210 series transmission. This genuine OEM assembly includes all necessary fasteners, seals, and positioning elements required to secure internal sub-assemblies during a rebuild or major repair. Positioned within the main gear train housing, this kit ensures that the TRANSMISSION HOUSING maintains proper alignment with the HOUS.FRONT SECT and the HOUSING REAR PART. The SKU 4657.183.086 is factory-matched to WG210 torque and vibration tolerances, eliminating guesswork in parts selection.

Symptoms of Failure

• Transmission housing oil seepage at mating flanges – Worn loose parts cause the CYLINDRICAL PIN to shift, breaking the seal between housing sections.
• Intermittent gear engagement hesitation – Loose fasteners allow the front and rear housing sections to micro-move under load, misaligning shift forks.
• Abnormal metallic rattling from bell housing area – Degraded retaining components fail to dampen vibration between the HOUS.FRONT SECT and main case.
• Torque converter bolt loosening – Missing or stretched cap screws in the loose parts set allow converter flexplate misalignment.

Technical Specifications

Compatibility

This genuine ZF 4657.183.086 kit is engineered for the WG210 series but also fits WG180, WG200, and WG220 models that share the same housing bolt pattern.
