Overview
The ZF 0736.300.142 TORX SCREW is a critical fastening component engineered for the WG200, WG92, and WG98 series transmissions. This OEM genuine part secures the TRANSMISSION HOUSING assembly, ensuring precise alignment of internal gear sets and hydraulic circuits. Designed to withstand extreme torque loads and thermal cycling, the 0736.300.142 screw prevents loosening under vibration. When paired with the PERIPHERALS kit and RANGE SELECTOR mechanism, this fastener maintains the structural integrity of the valve body and clutch pack assembly. The SKU 0736.300.142 is a direct replacement for factory-installed hardware, offering corrosion-resistant performance in heavy-duty applications.
Symptoms of Failure
- Transmission fluid seepage at housing joints: A loose or stripped 0736.300.142 screw can compromise the seal between the HOUSING and main case, leading to visible oil drips under the vehicle.
- Intermittent gear slippage during load shifts: When this TORX screw loses clamping force, internal clearances shift, causing delayed engagement in WG200 and WG92 series units.
- Abnormal metallic rattling from the bell housing: A fractured 0736.300.142 allows the valve body to vibrate against the housing, producing a distinct chatter during acceleration.
- Erratic range selection in WG98 models: Insufficient torque on this fastener disrupts the RANGE SELECTOR linkage alignment, resulting in hard shifts or neutral lockout.
