Overview
The ZF 4616.199.174 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 65 Series transmission. This OEM genuine part consolidates essential fasteners, seals, and positioning components required during a transmission overhaul or housing replacement. The kit ensures proper clamping force and leak-free sealing between the main transmission housing and auxiliary housings. When installing a new 4616101140: TRANSMISSION HOUSING, this loose parts set provides the necessary hardware to secure the assembly. The SKU 4616.199.174 is factory-matched to ZF’s original tolerances, eliminating guesswork during rebuilds.
Symptoms of Failure
- External oil seepage at housing joints: Worn or missing components from this kit cause transmission fluid to weep between the main housing and auxiliary covers, leaving visible drips under the vehicle.
- Loose or rattling housing sections: Degraded fasteners or missing hardware from the 4616.199.174 set allow the 4616301304: HOUSING to vibrate against the main case, producing a distinct metallic rattle during gear changes.
- Intermittent gear engagement hesitation: When the 4616301309: HOUSING shifts out of alignment due to failed fasteners, internal shaft alignment is compromised, causing delayed or rough shifting.
- Contaminated transmission fluid: A compromised seal from this kit allows dirt and moisture ingress, leading to premature clutch pack wear and fluid discoloration.
