ZF 4616.199.168 LOOSE PARTS for WG65 | OEM Genuine Part

Overview

The ZF 4616.199.168 LOOSE PARTS kit is a critical service assembly designed specifically for the WG 65 Series transmission. This OEM genuine part contains the necessary loose components required to secure and seal the transmission housing during rebuilds or major repairs. Positioned within the main casing assembly, this kit interfaces directly with the 4616101101: TRANSMISSION HOUSING and the 4616301304: HOUSING to ensure proper alignment and leak-free operation. The SKU 4616.199.168 is frequently ordered as a preventative maintenance set when overhauling the WG65 gearbox.

Symptoms of Failure

When the components within the 4616.199.168 LOOSE PARTS kit degrade, operators typically encounter three distinct failure modes. First, external oil seepage around the main casing joint indicates that the included seals or gaskets have lost their integrity. Second, abnormal gear engagement noise or a slight vibration during shifting suggests that the fasteners have loosened, allowing internal play. Third, intermittent loss of hydraulic pressure can occur if the sealing elements fail, leading to sluggish clutch application. Finally, visible metal debris in the oil filter often points to worn locating pins or screws that have sheared.

Technical Specifications

Compatibility

This LOOSE PARTS kit is engineered for the ZF WG 65 Series, but its components are also shared across several heavy-duty transmission models. It is directly compatible with the WG180, WG200, and WG250 series. Additionally, it can be used in the WG120 and WG150 units where the housing interface matches. Always verify that the 0636011118: HEXAGON SCREW and the 4616301309: HOUSING are present in your assembly before installation.
