Overview
The ZF 4646.199.067 LOOSE PARTS set is a critical OEM genuine service kit designed specifically for the WG 250 Series transmission. This assembly contains the essential loose hardware and small components required to secure and seal internal transmission assemblies during a rebuild or overhaul. Positioned within the main gearcase, these parts interface directly with the TRANSMISSION HOUSING and the HOUSING to ensure proper alignment and torque retention. The SKU 4646.199.067 is often ordered as a complementary kit when replacing the COVER or performing a full clutch pack replacement on the WG250.
Symptoms of Failure
When the components within the 4646.199.067 LOOSE PARTS kit begin to degrade or are missing, operators will notice distinct operational issues. Oil seepage at the housing joint is a primary indicator, often caused by worn fasteners or gaskets that no longer maintain clamping force. Intermittent gear engagement or slipping occurs when loose hardware allows internal shafts to shift out of tolerance. Abnormal vibration during torque converter lockup signals that retaining elements have fatigued. Finally, difficulty in removing or installing the transmission cover suggests that the loose parts have corroded or stripped, requiring immediate replacement of the 4646.199.067 kit.

Compatibility
This LOOSE PARTS kit is engineered for the ZF WG 250 Series transmission family. Based on its design and fastener configuration, it is also compatible with the WG180 and WG200 models that share the same housing architecture. The 4646.199.067 kit is required when servicing any WG-series transmission that utilizes the COVER and TRANSMISSION HOUSING assembly. For WG210 or WG300 variants, verify the housing bolt pattern before ordering, as the HEXAGON SCREW length may differ.
