ZF 4642.199.500 LOOSE PARTS for WG200 | OEM Genuine Part

Overview

The ZF 4642.199.500 LOOSE PARTS kit is a critical service assembly designed for the WG 200 Series powershift transmissions. This OEM genuine part consolidates the essential small components required to maintain the integrity of the transmission’s hydraulic and mechanical circuits. Specifically, the 4642.199.500 SKU includes the necessary fasteners, seals, and positioning elements that secure the TRANSMISSION HOUSING and the TRANSMISSION HOUSING assembly. Without this loose parts set, the internal alignment of the gear train and valve body cannot be guaranteed, leading to premature wear of the entire drivetrain.

Symptoms of Failure

When the components within the 4642.199.500 kit degrade, operators will notice distinct operational failures. Oil leaks around the bell housing are the most common symptom, often caused by degraded seals that are part of this kit. Another critical sign is erratic gear engagement or slipping under load, which occurs when the fasteners securing the valve body lose their torque retention. You may also experience abnormal vibration during torque converter lockup, indicating that the positioning dowels are worn. Finally, contaminated transmission fluid with metallic debris can appear if the loose parts fail and allow metal-on-metal contact inside the housing.

Technical Specifications

Compatibility

This loose parts kit is specifically engineered for the WG 200 Series transmissions, including the WG180, WG200, and WG210 variants. It is also compatible with select ZF Ergopower and Ecomat models that share the same housing architecture. When replacing this kit, always inspect the COVER PLATE for warping and the O-RING for compression set. The kit ensures proper sealing between the main casing and the auxiliary drive units.
