Overview
The ZF 6073.017.118 is a critical OEM genuine component engineered specifically for the WG 160 Series transmission. This precision-machined part functions as a key interface within the hydraulic control assembly, ensuring accurate oil flow regulation and clutch engagement timing. As a direct factory replacement, the SKU 6073.017.118 guarantees exact fitment and original ZF performance standards. When installed alongside the 4656201085: HOUS.FRONT SECT, it forms a sealed pressure boundary that prevents cross-contamination between lubrication circuits. This part is essential for maintaining the WG160’s characteristic shift quality under heavy industrial loads.
Symptoms of Failure
- Delayed or harsh shifting: A worn 6073.017.118 can cause erratic clutch pack engagement, leading to jarring gear changes during acceleration or deceleration.
- Transmission fluid seepage: Degraded sealing surfaces often result in visible oil leaks around the valve body area, particularly near the 0634313603: O-RING interface.
- Intermittent gear slip: Internal wear may cause pressure loss, allowing the transmission to momentarily lose drive power under load, especially in higher gears.
- Contaminated hydraulic fluid: Metal debris from a failing component can circulate through the system, accelerating wear on adjacent parts like the 0631306816: CYLINDRICAL PIN.

Compatibility
This genuine ZF part is primarily designed for the WG 160 Series transmission, commonly found in medium-duty trucks, buses, and construction equipment. It is also compatible with the WG 180 and WG 200 series transmissions that share the same valve body architecture. The 6073.017.118 integrates directly with the 0636115293: 螺栓 mounting points and requires proper torque sequencing during installation. Always verify your transmission’s serial number against ZF’s official compatibility chart before ordering.

Frequently Asked Questions
Q: Can the 6073.017.118 be installed without replacing the O-ring?
A: No. ZF recommends always replacing the 0634313603: O-RING simultaneously, as the old seal will have compressed and may leak under new component pressure.
Q: How do I verify this part fits my WG160 transmission?
A: Check the transmission’s data plate for the model code. The 6073.017.118 is compatible with WG160 variants built after 2012. For earlier units, cross-reference the serial number with ZF’s technical bulletin.
Q: What torque specification is required for the mounting bolts?
A: Use 28 Nm (20.6 ft-lbs) for the 0636115293: 螺栓 fasteners. Always tighten in a star pattern to avoid warping the valve body surface.
