ZF 6073.017.142 for WG190 | OEM Genuine Part

Overview

The ZF 6073.017.142 is a critical OEM genuine component engineered specifically for the WG 190 Series transmission family. This part functions as a precision-machined control element within the hydraulic valve body assembly, regulating oil flow to ensure smooth clutch engagement and consistent gear shifts under heavy-duty industrial loads. The SKU 6073.017.142 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in WG190 transmissions. When installed alongside the 4657201161: HOUS.FRONT SECT, this part maintains the structural integrity of the front housing assembly, preventing pressure loss and ensuring reliable operation in demanding environments.

Symptoms of Failure

• Delayed or harsh gear engagement: When the 6073.017.142 wears, hydraulic pressure drops, causing noticeable hesitation or jarring shifts—often searched as “ZF WG190 transmission shifting hard.”
• Internal oil leaks: Degraded sealing surfaces lead to fluid bypass, visible as puddles under the bell housing or low fluid levels without external drips.
• Erratic clutch slip under load: Worn components fail to hold pressure, resulting in RPM flare during acceleration—a common symptom described as “WG190 transmission slipping in forward gears.”
• Transmission overheating: Inefficient oil circulation from a failing part increases operating temperatures, triggering warning lights or burnt fluid odor.

Technical Specifications

Compatibility

This genuine ZF part is designed for the WG 190 Series, but its application extends to closely related ZF transmission models that share the same valve body architecture. Compatible transmissions include the WG180, WG190, WG200, and select variants of the WG150 series used in off-highway vehicles, forklifts, and construction equipment. Always verify your transmission’s serial number before ordering. For a complete rebuild, pair this part with the 0636115293: 螺栓 to secure the housing, and replace the 0634313603: O-RING to prevent fluid bypass. The 0631306816: CYLINDRICAL PIN is also essential for precise alignment during reassembly.

Frequently Asked Questions

Q: How do I know if the ZF 6073.017.142 is the correct part for my WG190 transmission?
A: Verify your transmission’s model number and serial plate. This SKU is specifically for WG190 valve body assemblies. If you have a WG180 or WG200, cross-reference the part dimensions in the technical table above.

Q: Can I reuse the old O-ring and bolts when installing this part?
A: No. ZF recommends always replacing the 0634313603: O-RING and 0636115293: 螺栓 during service to guarantee leak-free performance and proper torque retention.

Q: What causes premature failure of this part?
A: Common causes include contaminated hydraulic fluid, over-torquing during installation, and operating the transmission beyond its rated pressure range. Always pair with a clean 4657301032: SCREEN SHEET to protect the valve body.
