ZF 4651.183.029 LOOSE PARTS for WG100 | OEM Genuine Part

Overview

The ZF 4651.183.029 LOOSE PARTS kit is a critical service component designed specifically for the WG 100 Series transmission. This genuine OEM assembly includes all necessary fasteners, retainers, and positioning elements required to secure internal sub-assemblies within the gearbox housing. The SKU 4651.183.029 functions as a master retention set, ensuring that components such as the 4651101006: TRANSMISSION HOUSING and the 4651301034: HOUSING remain properly aligned under high-torque loads. Without this loose parts kit, the structural integrity of the transmission assembly is compromised, leading to premature wear on adjacent hardware.

Symptoms of Failure

When the 4651.183.029 LOOSE PARTS begin to degrade, operators will notice distinct operational issues. Intermittent gear slippage under load is a primary indicator, often misdiagnosed as a clutch problem. Another common failure symptom is abnormal vibration at specific RPM ranges, caused by loose retainers allowing shaft play. Technicians frequently report difficulty engaging or disengaging gears when these parts are worn, as the alignment tolerances shift. Finally, visible metal debris in the transmission fluid suggests that the loose parts have fractured, requiring immediate replacement of the kit and inspection of the 0634303928: O-RING for secondary sealing damage.

Technical Specifications

Compatibility

This genuine ZF loose parts kit is engineered for the WG 100 Series, but its retention geometry also supports select models in the WG 180 and WG 200 families. Specifically, it is a direct fit for transmissions requiring the 4651301013: HOUSING interface. The kit is validated for use in WG 100, WG 120, WG 150, WG 180, and WG 200 series units manufactured after 2012. Always verify the housing casting number before installation, as earlier revisions may require a different retention profile.
