ZF 6073.017.115 for WG190 | OEM Genuine Part

Overview

The ZF 6073.017.115 is a precision-engineered OEM genuine component specifically designed for the WG 190 Series transmission. This part functions as a critical control element within the valve body assembly, regulating hydraulic pressure to ensure smooth gear engagement and consistent clutch application. The SKU 6073.017.115 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in heavy-duty commercial vehicle transmissions. When installed alongside the 4657201161: HOUS.FRONT SECT, it ensures proper alignment and sealing of the hydraulic circuit.

Symptoms of Failure

• Delayed or harsh shifting: A worn 6073.017.115 can cause erratic pressure modulation, leading to noticeable lag when shifting between gears or abrupt engagement that jars the driveline.
• Transmission fluid leaks at the valve body: Degraded sealing surfaces allow pressurized ATF to escape, often pooling near the bell housing or dripping from the pan gasket area.
• Intermittent gear slipping under load: When the component fails to maintain steady hydraulic pressure, the transmission may momentarily lose torque transfer, especially during uphill climbs or heavy hauling.
• Erratic shift patterns in cold weather: A failing part can cause inconsistent cold-start behavior, with the transmission either refusing to upshift or holding gears too long until the fluid warms.

Technical Specifications

Compatibility

Frequently Asked Questions

Q: How do I know if the 6073.017.115 is the correct part for my WG190 transmission?
A: Verify your transmission’s serial number and consult the ZF parts catalog. The 6073.017.115 is a direct OEM replacement for the WG190 valve body assembly. If you experience erratic shifting or fluid leaks, this component is a common failure point.

Q: Can I install this part without replacing the O-ring and bolts?
A: ZF strongly recommends replacing the 0634313603: O-RING and 0636115293: 螺栓 simultaneously to prevent fluid leaks and ensure proper torque retention. Reusing old seals can lead to premature failure.

Q: What tools are required for replacement?
A: You will need a torque wrench (capable of 12 Nm), a hex key set, and a soft mallet for aligning the 0631306816: CYLINDRICAL PIN. Always clean the mating surfaces of the 4657201161: HOUS.FRONT SECT before installation.
