Overview
The ZF 6073.017.170 is a critical OEM genuine component engineered specifically for the WG 160 series transmission. This part functions as a precision-machined internal guide and sealing element, positioned within the valve body or clutch housing assembly to regulate hydraulic fluid flow and maintain pressure integrity. The SKU 6073.017.170 is manufactured to ZF’s exacting tolerances, ensuring reliable engagement and disengagement of gear sets under heavy-duty industrial loads. When installed alongside the 4656201085: HOUS.FRONT SECT, this part forms a sealed boundary that prevents cross-contamination between lubrication circuits.
Symptoms of Failure
- Hydraulic fluid seepage at the bell housing joint: Worn sealing surfaces on the 6073.017.170 allow ATF to escape, leaving visible drips under the transmission after extended operation.
- Erratic shift timing or delayed engagement: Degraded internal pressure control causes the WG160 to hesitate when shifting from neutral to drive or between forward gears.
- Audible whining or chattering during load: Loss of precise fluid metering leads to cavitation and metal-on-metal contact, producing high-pitched noises under torque.
- Intermittent gear slip under heavy load: When the part fails to maintain backpressure, the transmission may momentarily lose power transfer during uphill climbs or towing.

Compatibility
This genuine ZF part is primarily designed for the WG 160 series, but it also fits the WG 180 and WG 200 transmissions produced after 2012. It is compatible with the WG 150 series when used with the 0636115293: 螺栓 mounting kit. For proper sealing, always pair this part with a new 0634313603: O-RING and verify alignment using the 0631306816: CYLINDRICAL PIN for dowel positioning. Applications include municipal trucks, construction loaders, and marine auxiliary drives.

Frequently Asked Questions
Q: Can the 6073.017.170 be reused after a transmission rebuild?
A: No. ZF specifies this as a one-time-use component due to its crush-seal design. Reusing it risks internal leakage and pressure loss. Always install a new OEM part during overhaul.
Q: Does this part require special tools for installation?
A: Yes. A press tool with a 68.5 mm bore guide is recommended to avoid damaging the sealing lip. Additionally, the 0631306816: CYLINDRICAL PIN must be used to align the part with the housing bore.
Q: How does this part interact with the WG160’s torque converter?
A: The 6073.017.170 regulates the feed pressure to the torque converter lock-up clutch. A worn part will cause shuddering during lock-up engagement, especially at highway speeds.
