ZF 4657.183.252 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.252 LOOSE PARTS set is a critical service kit designed specifically for the WG 210 series transmission. This assembly contains the necessary fasteners, seals, and positioning elements required to secure internal components during a rebuild or major repair. As an OEM genuine part, the SKU 4657.183.252 ensures precise fitment within the transmission housing, maintaining the exact tolerances needed for reliable power flow. This loose parts kit typically interfaces with the main casing and front section, acting as the final lock-up for the gear train assembly.

Symptoms of Failure

When the components within the 4657.183.252 kit begin to degrade, operators often notice specific operational issues. Common failure symptoms include:

• Oil leaks at the housing seam: Worn gaskets or loose fasteners from this kit can cause transmission fluid to seep between the TRANSMISSION HOUSING and the HOUS.FRONT SECT, leading to low fluid levels.
• Gear slipping under load: If the fixing elements fail, internal clearances shift, causing the clutch packs to engage inconsistently.
• Unusual vibration or noise: Loose retaining hardware can allow the HOUSING REAR PART to shift, creating driveline shudder during acceleration.
• Delayed engagement: A compromised seal within the kit can reduce hydraulic pressure, resulting in a noticeable pause when shifting from neutral to drive.

Technical Specifications

Compatibility

This loose parts kit is engineered for the WG 210 series but shares mounting patterns with several other ZF models. It is compatible with the WG180, WG200, and WG250 transmissions when used in conjunction with the correct HOUSING REAR SECTION. The kit is also suitable for rebuilds of the WG 211 and WG 212 variants. Always verify the housing casting number before installation, as the 4657.183.252 set is specifically calibrated for the bolt pattern found on the WG210 main case.
