ZF 4651.231.009 OIL DIPSTICK for WG100/WG200 | OEM Genuine Part

Overview

The ZF 4651.231.009 OIL DIPSTICK is a precision-engineered fluid level indicator specifically designed for the WG100 and WG200 series transmissions. This OEM genuine part sits within the transmission housing, providing a direct reading of the oil sump level to ensure proper lubrication and hydraulic pressure. The SKU 4651.231.009 is manufactured to ZF’s exacting tolerances, guaranteeing an accurate seal and reliable measurement in heavy-duty industrial applications. Without this component, operators cannot verify oil condition or quantity, risking premature wear on internal assemblies such as the TRANSMISSION HOUSING and TRANSMISSION HOUSING.

Symptoms of Failure

• Oil seepage around the dipstick tube: A worn or cracked dipstick allows transmission fluid to escape, leaving visible puddles under the vehicle. This often leads to low fluid levels and erratic shifting.
• Inaccurate oil level readings: When the dipstick’s markings fade or the shaft bends, operators receive false readings, causing overfilling or underfilling of the transmission sump.
• Gear slipping or delayed engagement: Insufficient oil due to a failed dipstick seal reduces hydraulic pressure, resulting in hesitation when shifting between forward and reverse gears.
• Contaminated fluid ingress: A broken dipstick cap or missing O-ring allows dirt and moisture to enter the transmission, accelerating wear on the SCREW PLUG and O-RING seals.

Technical Specifications

Compatibility

This dipstick is engineered for ZF’s WG100 and WG200 series transmissions, including models such as WG180, WG200, WG210, and WG250. It directly replaces the original factory-installed unit in both on-highway and off-highway applications. For complete assembly verification, ensure the dipstick tube aligns with the COVER PLATE and SHIFT SYSTEM components. Always pair this part with a fresh O-RING to maintain a leak-free seal.
