Overview
The ZF 6009.065.250 is a critical OEM genuine component engineered specifically for the WG 110 series transmission. This part functions as a precision-machined guide or bushing element within the hydraulic control assembly, ensuring accurate oil flow and pressure regulation during gear shifts. The SKU 6009.065.250 sits directly adjacent to the main valve body, where it interfaces with the TRANSMISSION HOUSING to maintain structural integrity under high torque loads. Without this part, the transmission cannot maintain consistent clutch engagement, leading to operational inefficiency.
Symptoms of Failure
- Delayed or harsh shifting: When the 6009.065.250 wears, hydraulic pressure drops, causing noticeable lag between gear changes or abrupt engagement.
- Transmission fluid seepage: A worn guide surface allows oil to bypass seals, resulting in visible drips around the HOUSING interface.
- Intermittent gear slipping: Operators report the transmission momentarily loses power under load, especially when climbing or towing.
- Unusual whining noise: Metal-on-metal contact from a degraded part produces a high-pitched sound during acceleration.

Frequently Asked Questions
Q: Can the 6009.065.250 be reused after removal?
A: No. This OEM part is designed for single-use installation. Reusing it risks dimensional distortion and fluid leakage. Always replace it with a new genuine ZF part.
Q: What torque specification should I use when installing this part?
A: For the 6009.065.250, tighten the retaining screws to 25 Nm (18 ft-lb) when paired with the O-RING 0634303928. Over-torquing can deform the housing bore.
Q: Does this part fit the ZF WG 180 transmission?
A: Yes, but only if you also install the HOUSING 4651301033. The WG 180 uses a different bolt pattern that requires this adapter housing for proper alignment.
