ZF 4642.199.758 LOOSE PARTS for WG150 | OEM Genuine Part

Overview

The ZF 4642.199.758 LOOSE PARTS kit is a critical service component designed for the WG 150 Series transmission. This genuine OEM assembly includes all necessary loose hardware—such as seals, retainers, and small fasteners—required to secure internal shift mechanisms and fluid passages within the gearbox. Positioned directly within the main valve body and housing interface, the SKU 4642.199.758 ensures that all ancillary components remain properly seated under high torque and thermal cycling. Without this kit, the transmission cannot maintain hydraulic integrity, leading to pressure loss and erratic shifting.

Symptoms of Failure

When the 4642.199.758 LOOSE PARTS begin to degrade, operators typically notice oil leaks around the transmission housing due to compromised seal retention. A second common symptom is gear slipping under load, especially during upshifts, as loose fasteners allow valve body movement. Third, you may experience erratic shift timing or delayed engagement when the parts no longer hold the shift system in precise alignment. Finally, vibration at the bell housing can occur if the grooved studs or housing bolts lose their clamping force, a clear indicator that the loose parts set requires replacement.

Technical Specifications

Compatibility

This LOOSE PARTS kit is primarily engineered for the WG 150 Series transmission, but it also fits select variants in the WG 180 and WG 200 families where the valve body and housing geometry match. It is commonly used in ZF off-highway and industrial drivetrains. For proper fitment, always verify the housing type; the kit works with both the 4642101047: TRANSMISSION HOUSING and the 4642301207: TRANSMISSION HOUSING. Additionally, the 0730365067: TYPE PLATE and 0631311009: GROOVED STUD are often replaced simultaneously to ensure complete assembly integrity.
