ZF 4642.199.332 LOOSE PARTS for WG150 | OEM Genuine Part

Overview

The ZF 4642.199.332 LOOSE PARTS kit is a critical OEM genuine component designed specifically for the WG 150 series transmission. This assembly kit consolidates essential fasteners, seals, and positioning elements that secure internal hydraulic circuits and mechanical linkages within the transmission housing. As a loose parts set, it replaces worn or missing hardware that can compromise the structural integrity of the gearbox. The SKU 4642.199.332 is factory-matched to ZF’s exact tolerances, ensuring that every TRANSMISSION HOUSING and TRANSMISSION HOUSING maintains proper alignment under high-torque loads. Without this kit, the transmission’s internal pressure regulation and gear engagement become unreliable.

Symptoms of Failure

• Oil leaks around the housing seam: When the loose parts degrade, the seal between the TRANSMISSION HOUSING and the main case fails, causing fluid seepage that leads to low oil pressure and overheating.
• Gear slipping under load: Worn fasteners allow the valve body to shift slightly, interrupting hydraulic flow and causing erratic shifting or complete loss of drive in forward gears.
• Vibration or rattling from the bell housing: Missing or loose components create play in the GROOVED STUD mounting points, transmitting noise through the driveline during acceleration.
• Erratic shift timing: Degraded seals within the loose parts kit disrupt the governor pressure signal, leading to delayed or harsh upshifts in the WG150.

Technical Specifications

Compatibility

This loose parts kit is engineered for the ZF WG 150 series, but its design principles extend to the WG 180 and WG 200 transmissions that share the same housing architecture. It directly interfaces with the TRANSMISSION HOUSING and TRANSMISSION HOUSING used in these models. The kit also supports the WG 160 and WG 250 variants when paired with the correct GROOVED STUD and TYPE PLATE for identification. Always verify your transmission’s serial number against the OEM parts list before installation.
