Overview
The ZF 4642.199.206 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 150 series transmission. This genuine OEM part contains the essential fasteners, seals, and small components required to secure internal assemblies during a rebuild or major repair. The SKU 4642.199.206 ensures that all loose hardware within the clutch pack and planetary gear set area meets factory torque and fitment specifications. When paired with a new TRANSMISSION HOUSING (4642101047) or a TRANSMISSION HOUSING (4642301207), this kit prevents premature wear caused by incorrect hardware substitution.
Symptoms of Failure
When the loose parts in this kit degrade or are missing, operators typically notice these specific failure modes:
- Internal rattling or loose metallic noise during gear engagement, indicating that retaining fasteners have backed out inside the transmission housing.
- Intermittent loss of drive pressure caused by loose components obstructing oil passages within the valve body area.
- Oil seepage at housing seams due to degraded sealing washers or missing bolts that compromise the TYPE PLATE (0730365067) mounting integrity.
- Hard shifting or delayed engagement when the GROOVED STUD (0631311009) loses its torque retention, allowing shift forks to misalign.

Compatibility
This genuine loose parts kit is engineered for the ZF WG 150 series, but its hardware dimensions also apply to the WG 180 and WG 200 series when used with the same clutch housing interface. The kit is not compatible with the WG 120 or WG 250 series due to different bolt patterns. Always verify your transmission model against the TYPE PLATE (0730365067) before installation.
