Overview
The ZF 4657.183.087 LOOSE PARTS kit is a critical service component designed exclusively for the WG 210 series transmission. This genuine OEM assembly includes all necessary fasteners, seals, and positioning elements required to secure internal sub-assemblies during a rebuild or overhaul. Specifically, the 4657.183.087 kit interfaces directly with the main casing structure, ensuring that the TRANSMISSION HOUSING maintains proper alignment with the HOUS.FRONT SECT and the HOUSING REAR PART. Without this loose parts set, the gear train cannot achieve the precise axial clearances required for long-term durability. The SKU 4657.183.087 is factory-matched to the WG210 platform, eliminating guesswork during field repairs.
Symptoms of Failure
- Intermittent gear engagement loss – When the loose parts in this kit fatigue, the CYLINDRICAL PIN can shift, causing the shift fork to misalign and produce a “gear slipping under load” condition.
- Oil seepage at housing joints – Deteriorated sealing elements within the 4657.183.087 set lead to visible oil leaks between the front section and rear housing, often mistaken for a gasket failure.
- Abnormal vibration during torque converter lockup – Worn locating dowels allow micro-movement of the housing sections, generating a low-frequency shudder that worsens at highway speeds.
- Hard shifting or delayed engagement – Loose fasteners in this kit reduce clamping force on the valve body sandwich plate, resulting in sluggish clutch pack application.

Compatibility
This genuine ZF 4657.183.087 loose parts kit is engineered for the WG 210 series transmission family. Based on the part’s structural role, it is also fully compatible with the WG 180 and WG 200 models that share the same housing architecture. The kit directly replaces worn fasteners and alignment components in transmissions built between 2005 and 2020. For installations requiring the TRANSMISSION HOUSING replacement, this kit must be ordered simultaneously to ensure correct bolt torque and pin alignment. It is not cross-compatible with the WG 120 or WG 150 series due to different housing bolt patterns.
