ZF 4657.183.198 LOOSE PARTS for WG211 | OEM Genuine Part

Overview

The ZF 4657.183.198 LOOSE PARTS set is a critical service kit designed specifically for the WG 211 series transmission. This OEM genuine assembly contains the necessary fasteners, seals, and positioning elements required to secure internal components during a major overhaul or rebuild. Positioned within the main gear case, this kit interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to ensure proper alignment and clamping force. The SKU 4657.183.198 is a factory-sealed package that eliminates guesswork when sourcing individual washers, bolts, and clips for the WG211 planetary assembly.

Symptoms of Failure

When the ZF 4657.183.198 LOOSE PARTS begin to degrade or are missing, operators often report intermittent gear slippage under load, particularly during torque converter lockup. A second common failure symptom is low hydraulic pressure at the clutch packs, which manifests as delayed engagement when shifting from neutral to drive. Technicians also frequently encounter metallic debris in the oil pan caused by loose fasteners rattling against the HOUSING REAR PART. Finally, a persistent oil weep at the housing split line indicates that the included sealing elements have fatigued, allowing fluid migration past the mating surfaces.

Technical Specifications

Compatibility

This LOOSE PARTS kit is engineered for the ZF WG 211 series, but it also cross-fits select models in the WG180 and WG200 families due to shared housing architecture. Specifically, it is compatible with WG180-1, WG200-2, and WG211-3 transmissions manufactured after 2012. The kit includes the CYLINDRICAL PIN that aligns the front section to the main case, ensuring concentricity of the input shaft. Always verify your transmission serial number against the ZF parts catalog before installation, as minor revisions may require additional components.
