ZF 4642.199.162 LOOSE PARTS for WG150 | OEM Genuine Part

Overview

The ZF 4642.199.162 LOOSE PARTS kit is a critical service component engineered specifically for the WG 150 Series transmission. This genuine OEM assembly includes all necessary fasteners, seals, and small hardware required to secure and seal the transmission housing during rebuilds or major repairs. Positioned at the main casing interface, the SKU 4642.199.162 ensures that internal components remain properly aligned and protected from contamination. Without this loose parts set, even a perfectly rebuilt gearbox can suffer from premature wear due to vibration or fluid ingress.

Symptoms of Failure

• Oil seepage at housing seams: When the 4642.199.162 loose parts degrade, you may notice fluid weeping around the main case joints, especially after extended operation under load.
• Transmission gear slipping under torque: Worn or missing fasteners from this kit can allow slight housing flex, leading to intermittent gear disengagement during heavy acceleration.
• Abnormal vibration or rattle: Loose hardware inside the assembly creates a distinct metallic noise at idle or low RPM, indicating that the loose parts have lost their clamping force.
• Difficulty maintaining hydraulic pressure: A compromised seal from this kit can cause internal pressure drops, resulting in delayed shifts or harsh engagement.

Technical Specifications

Compatibility

This loose parts kit is primarily designed for the WG 150 Series transmission. It is also compatible with the WG 180 and WG 200 models where the main housing interface shares identical bolt patterns. For WG 120 and WG 250 variants, verify housing dimensions before installation. The kit works in conjunction with the 4642101109 TRANSMISSION HOUSING and the 4642301205 TRANSMISSION HOUSING to ensure a leak-free assembly. Always pair with a new 0730365125 TYPE PLATE for accurate identification, and use the 0631311009 GROOVED STUD for precise alignment during installation.
