Overview
This OEM genuine ZF 6009.092.313 is a critical internal component engineered specifically for the WG 160 Series transmission. Designed to manage hydraulic pressure distribution within the valve body assembly, this part ensures precise clutch engagement and smooth gear transitions under heavy load. The SKU 6009.092.313 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in commercial vehicle drivelines. It interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain structural integrity during high-torque operations.
Symptoms of Failure
- Erratic gear engagement or delayed shifting — Worn internal bores in the 6009.092.313 cause inconsistent hydraulic pressure, leading to harsh or hesitant gear changes.
- Transmission fluid seepage near the valve body — Degraded sealing surfaces allow ATF to escape, often visible as drips beneath the bell housing.
- Intermittent loss of drive in forward gears — A failing unit can cause pressure drops that result in momentary slipping, especially under load on inclines.
- Unusual whining or buzzing from the transmission sump — Cavitation or restricted fluid flow through a worn 6009.092.313 generates audible hydraulic noise.

Compatibility
While primarily designed for the WG 160 Series, the 6009.092.313 is also compatible with ZF WG180, WG200, and WG210 transmissions used in municipal trucks, refuse vehicles, and medium-duty construction equipment. It replaces earlier revision parts in the WG160 valve body stack. For full assembly integrity, pair this component with the HOUSING REAR PART and the HOUSING REAR PART to ensure correct alignment of the hydraulic circuits.

Frequently Asked Questions
Q: Can the 6009.092.313 be reused after a transmission rebuild?
A: No. This is a wear-critical component with precision-machined sealing surfaces. ZF recommends replacement during any major overhaul to prevent premature hydraulic failure.
Q: Does this part require special tools for installation?
A: Yes. A torque wrench calibrated to 45 Nm and a seal installer tool are required to avoid damaging the integrated PTFE lip seal during assembly.
Q: How does the 6009.092.313 differ from the earlier 6009.092.310 revision?
A: The .313 revision features a hardened steel bore insert that improves resistance to cavitation erosion, extending service life by approximately 30% in high-cycle applications.
