Overview
This OEM genuine ZF 4651.352.053 component is a critical hydraulic control element engineered specifically for the WG 100 and WG 110 series transmissions. Positioned within the valve body assembly, this part regulates fluid pressure and flow to ensure precise clutch engagement and smooth gear transitions. The SKU 4651.352.053 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in heavy-duty industrial drivetrains. When paired with a properly sealed TRANSMISSION HOUSING, this part maintains the hydraulic integrity required for sustained torque handling.
Symptoms of Failure
- Delayed or harsh shifting: A worn 4651.352.053 can cause erratic pressure drops, leading to noticeable hesitation or jarring when the transmission changes gears.
- Internal fluid leakage: Degraded sealing surfaces allow hydraulic oil to bypass, resulting in low fluid levels and visible puddling under the transmission bell housing.
- Transmission overheating: Inadequate pressure regulation forces the system to work harder, generating excessive heat that accelerates wear on adjacent components.
- Intermittent gear slippage: As the part loses its ability to hold steady pressure, the transmission may momentarily lose power delivery under load, especially during uphill climbs.

Compatibility
This genuine ZF part is designed for the WG 100 and WG 110 transmission series, commonly found in municipal trucks, refuse vehicles, and medium-duty construction equipment. It also serves as a direct fit for the WG 120, WG 150, and WG 180 models when used in conjunction with the correct HOUSING assembly. For WG 200 and WG 250 variants, verify that the O-RING seal matches your application’s groove dimensions. Always pair this valve component with a compatible HOUSING to prevent cross-threading and fluid bypass.

Frequently Asked Questions
Q: Can the 4651.352.053 be used in a ZF WG 200 transmission?
A: Yes, it is compatible with WG 200 models, but you must verify that the O-RING seal matches the updated groove depth found in later production units.
Q: What causes premature failure of this valve component?
A: Contaminated hydraulic fluid is the primary cause. Always replace the SCREEN SHEET and inspect the HOUSING for scoring when installing a new 4651.352.053.
Q: Is this part interchangeable with aftermarket alternatives?
A: Only OEM genuine ZF parts guarantee the exact metallurgy and seal geometry required for long service life. Aftermarket copies often fail to maintain proper pressure regulation under high-load conditions.
