Overview
The ZF 0501.224.243 OIL DIPSTICK is a precision-engineered fluid level indicator specifically designed for the WG 94 series transmission. This OEM genuine part sits within the transmission housing assembly, providing operators with an accurate method to verify oil levels during routine maintenance. The dipstick ensures that the hydraulic system maintains proper lubrication pressure, preventing premature wear on internal components. When paired with the 4661101039 TRANSMISSION HOUSING, this part forms a critical seal that protects against contamination ingress. The SKU 0501.224.243 is manufactured to ZF’s exacting tolerances, guaranteeing a perfect fit for WG94 gearboxes.
Symptoms of Failure
- Hydraulic oil seepage around the dipstick tube: A worn or cracked dipstick seal allows transmission fluid to escape, leaving visible puddles under the vehicle. This is often accompanied by a burning oil smell during operation.
- Inaccurate fluid level readings: When the dipstick’s markings degrade or the shaft bends, operators receive false oil level data, leading to overfilling or underfilling. This can cause gear slipping or harsh shifting in WG94 transmissions.
- Contaminated transmission fluid: A broken dipstick cap or missing O-ring permits dirt and moisture to enter the gearbox through the fill tube. This accelerates wear on components like the 0631306174 CYLINDRICAL PIN and valve bodies.
- Difficulty inserting or removing the dipstick: Physical deformation from heat cycles or impact prevents the dipstick from seating properly, often resulting in rattling noises during operation.

Compatibility
This dipstick is engineered for the ZF WG 94 series, but it also fits select models in the WG180, WG200, and WG210 families when used with the appropriate 4661301109 HOUSING II. The 0501.224.243 is compatible with WG94-1, WG94-2, and WG94-3 variants. For retrofit applications, verify that the transmission housing includes the correct dipstick tube boss. The 0769123894 TYPE PLATE on your gearbox will confirm the exact series designation.
