Overview
The ZF 4657.306.107 GASKET is a critical sealing component engineered for the WG 190 and WG 210 series transmissions. Positioned between the transmission housing and the valve body assembly, this OEM genuine part ensures a leak-proof barrier against high-pressure hydraulic fluid. The SKU 4657.306.107 is precision-molded to maintain consistent clamping force, preventing contamination ingress and fluid loss. When replacing this gasket, it is common practice to also inspect the 4657120005: PRESSURE REGULATOR for wear, as both components work in tandem to stabilize system pressure.
Symptoms of Failure
- Hydraulic fluid seepage at the valve body interface – Visible oil drips or wet spots around the transmission pan or housing joint, often noticed during routine inspections.
- Erratic gear engagement or delayed shifting – A worn gasket allows air to enter the hydraulic circuit, causing soft shifts or hesitation when moving from neutral to drive.
- Low transmission fluid pressure warnings – Internal leakage past the gasket reduces line pressure, triggering dashboard alerts or diagnostic trouble codes (DTCs).
- Contaminated fluid with debris – A degraded gasket can shed particles into the oil, accelerating wear on components like the 0501211384: VALVE and 0630532183: INDENTED RING.

Compatibility
This gasket is directly compatible with ZF WG 191 and WG 211 series transmissions, as well as earlier WG 180 and WG 200 models that share the same valve body footprint. It is a direct replacement for the OEM seal used in off-highway vehicles, construction equipment, and marine gearboxes. For complete assembly integrity, always pair this gasket with a new 4656306145: PISTON to ensure proper sealing under dynamic loads.

Frequently Asked Questions
Q: Can I reuse the old gasket if it looks intact?
No. ZF gaskets are single-use components designed to crush and conform during initial torque. Reusing a gasket risks internal leaks and pressure loss, especially when paired with a new 4657120005: PRESSURE REGULATOR.
Q: Does this gasket fit the WG 180 transmission?
Yes, the 4657.306.107 is compatible with WG 180, WG 200, WG 191, and WG 211 series, provided the valve body mating surface is clean and undamaged.
Q: What torque specification should I use for the valve body bolts?
ZF recommends 25 Nm for M8 bolts and 12 Nm for M6 bolts when installing this gasket. Always consult your service manual for exact values.
