Overview
The ZF 6073.017.218 is a critical OEM genuine component engineered specifically for the WG 160 series transmission. This precision-machined part functions as a hydraulic control element, regulating oil flow and pressure within the valve body assembly to ensure smooth gear engagement and consistent torque delivery. As a direct factory replacement, the SKU 6073.017.218 guarantees exact dimensional tolerances and material specifications required for reliable long-haul operation. When installed alongside the 4656201085: HOUS.FRONT SECT, it forms the primary sealing interface that prevents cross-contamination between hydraulic circuits.
Symptoms of Failure
- Delayed or harsh shifting – Worn internal bores cause erratic clutch pack engagement, often misdiagnosed as solenoid failure.
- Low hydraulic pressure warnings – Degraded sealing surfaces lead to pressure drops below 8 bar during load cycles, triggering dashboard alerts.
- Transmission fluid contamination – Micro-fractures in the casting allow metallic debris to bypass the filter, accelerating wear on adjacent components like the 0634313603: O-RING.
- Intermittent neutral engagement – Thermal expansion of degraded material causes temporary loss of drive in stop-and-go traffic.

Compatibility
This OEM part is validated for the ZF WG 160 series and its direct derivatives. While primarily designed for WG160, it also fits WG180 and WG200 transmissions produced after 2012 when used with the correct 0636115293: 螺栓 fasteners. Always verify housing compatibility by checking the front section casting number; the 4656201085: HOUS.FRONT SECT must match revision C or later. Not suitable for WG210 or off-highway variants without adapter kits.

Frequently Asked Questions
Q: Can I use this part in a ZF WG180 transmission without modifications?
A: Yes, the 6073.017.218 is physically interchangeable with WG180 units, but you must replace the 0634313603: O-RING and 0631306816: CYLINDRICAL PIN simultaneously to maintain sealing integrity.
Q: What torque specification applies to the retaining bolts?
A: Tighten the 0636115293: 螺栓 to 45 Nm ±3 Nm in a crosswise pattern. Always use new fasteners after removal.
Q: How do I identify a counterfeit 6073.017.218?
A: Genuine parts have a laser-etched ZF logo and date code on the flat face. Counterfeits often lack the 4656201085: HOUS.FRONT SECT alignment witness mark.
