ZF 4657.183.267 LOOSE PARTS for WG210 | OEM Genuine Part

Overview

The ZF 4657.183.267 LOOSE PARTS kit is a critical service component engineered specifically for the WG 210 Series transmission. This genuine OEM assembly contains the necessary fasteners, seals, and positioning elements required to secure internal hydraulic circuits and structural sections within the gearbox. As a loose parts set, it functions as a consolidation of small but vital hardware that prevents fluid bypass and maintains the alignment of major sub-assemblies. The SKU 4657.183.267 is the direct replacement for the original factory configuration, ensuring that every bolt, pin, and plate meets ZF’s exacting tolerances for pressure retention and vibration resistance.

Symptoms of Failure

When the components within the 4657.183.267 loose parts kit degrade or are omitted during a rebuild, operators often report external oil seepage from the housing joint lines, particularly around the mid-plate and rear cover interfaces. A second common failure mode is intermittent gear slippage under moderate load, caused by loosened fixing plates allowing clutch pack clearances to shift. Technicians also encounter erratic shift timing or delayed engagement when the cap screws and cylindrical pins lose their clamping force, leading to micro-movement of the valve body. Finally, contaminated transmission fluid with metallic debris can appear if the screen sheets become dislodged, allowing particles to circulate through the hydraulic system.

Technical Specifications

Compatibility

This loose parts kit is primarily designed for the ZF WG 210 Series transmission, but its hardware configuration also supports the WG 180, WG 200, and WG 250 models due to shared housing architecture. The kit interfaces directly with the 4657101080: TRANSMISSION HOUSING and the 4657201167: HOUS.FRONT SECT. For complete assembly, the rear structure requires either the 4657201171: HOUSING REAR PART or the 4657298103: HOUSING REAR SECTION, depending on the specific transmission variant. Always verify the housing casting numbers before installation.
