Overview
The ZF 4616.183.006 LOOSE PARTS kit is a critical service component designed specifically for the WG 65 series transmission. This OEM genuine assembly contains the necessary loose hardware and small components required to secure and seal internal transmission sections during rebuilds or repairs. The SKU 4616.183.006 typically includes fasteners, washers, and positioning elements that interface directly with the main transmission housing and auxiliary housings. Without this kit, proper torque specifications and sealing integrity cannot be maintained, leading to premature wear. It is often replaced in conjunction with the 4616101140 TRANSMISSION HOUSING to ensure all mating surfaces are correctly secured.
Symptoms of Failure
- Transmission oil seepage at housing joints: When the loose parts in this kit fatigue or corrode, sealing rings lose compression, causing slow oil leaks around the 4616301304 HOUSING interface.
- Loose or rattling transmission casing: Worn hexagon screws or missing components from the kit can cause audible vibration and a feeling of instability in the drivetrain during acceleration.
- Intermittent gear engagement hesitation: If the 0636011118 HEXAGON SCREW or similar fasteners lose torque, internal alignment shifts, leading to delayed or rough shifting.
- Increased operating noise from the bell housing area: Degraded loose parts allow micro-movement between the 4616301309 HOUSING and the main case, amplifying gear whine and mechanical chatter.

Compatibility
This ZF 4616.183.006 LOOSE PARTS kit is engineered for the WG 65 series transmission family. Based on the part type and application, it is compatible with the following ZF models: WG65, WG80, WG120, WG180, WG200. It is also suitable for select off-highway and marine variants that share the WG housing architecture. Always verify fitment by cross-referencing your transmission serial number with the OEM parts catalog. For complete assembly, this kit is often used alongside the 0636011038 HEXAGON SCREW and 0636016015 HEXAGON SCREW for additional mounting points.
