Overview
The ZF 0501.314.138 is a critical OEM genuine component engineered specifically for the WG 100, WG 110, and WG 150 series transmissions. This part functions as a precision-machined guide or sealing element within the hydraulic control assembly, ensuring proper fluid routing and pressure regulation during gear shifts. The SKU 0501.314.138 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in heavy-duty industrial drivetrains. When installed alongside a robust TRANSMISSION HOUSING (4642101109) or a TRANSMISSION HOUSING (4642301205), this part maintains the structural integrity of the valve body circuit.
Symptoms of Failure
When the ZF 0501.314.138 wears out, operators typically notice three distinct failure modes. First, intermittent gear slipping under load occurs as hydraulic pressure bleeds past the degraded component. Second, delayed engagement when shifting from neutral to drive becomes common, often accompanied by a harsh clunk. Third, visible oil seepage around the transmission housing seam indicates the seal has lost its elasticity. Addressing these symptoms early prevents damage to the TYPE PLATE (0730365125) and surrounding hardware.

Compatibility
This genuine ZF 0501.314.138 part is directly compatible with the WG 100, WG 110, and WG 150 transmission series. It also fits select variants of the WG 180 and WG 200 models where the hydraulic control block shares the same bore pattern. For proper installation, ensure the mating surfaces are clean and that the GROOVED STUD (0631311009) is torqued to factory specifications. Always verify your transmission’s serial number against the OEM parts catalog before ordering.

Frequently Asked Questions
Q: Can I use the ZF 0501.314.138 in a WG 180 transmission?
A: Yes, this part is compatible with WG 180 models that share the same hydraulic control block design. However, always cross-reference your transmission’s serial number with the OEM parts list to confirm fitment.
Q: What tools are needed to replace this part?
A: A standard socket set, torque wrench, and seal pick are required. You will also need to remove the COVER PLATE (4644306500) to access the component.
Q: How often should the 0501.314.138 be inspected?
