Overview
The ZF 4651.199.043 LOOSE PARTS kit is a critical service component engineered specifically for the WG 100 series transmission. This genuine OEM assembly includes the necessary loose hardware and fasteners required to secure and seal internal transmission elements during a rebuild or overhaul. Positioned within the main gear train housing, this kit ensures that the TRANSMISSION HOUSING and HOUSING components remain properly torqued and leak-free under high-load industrial conditions. The SKU 4651.199.043 is a direct factory replacement, guaranteeing dimensional accuracy and material integrity for your ZF drivetrain.
Symptoms of Failure
When the 4651.199.043 LOOSE PARTS kit begins to degrade, operators often notice oil seepage around the housing mating surfaces, particularly after extended operation. A second common failure symptom is gear slipping or erratic shifting caused by loose fasteners allowing internal components to shift out of alignment. You may also detect unusual vibration or rattling noises from the transmission bell housing, indicating that the loose parts have lost their clamping force. Finally, contaminated transmission fluid with metallic debris can signal that the kit’s hardware has fatigued, leading to internal wear.

Compatibility
This genuine ZF part is primarily designed for the WG 100 series transmission family. Based on its application in the loose parts assembly, it is also compatible with the WG 180, WG 200, and WG 250 models that share the same housing architecture. The kit interfaces directly with the HOUSING and requires a fresh O-RING to ensure a proper seal during installation. Always verify your transmission serial number against ZF’s compatibility chart before ordering.
