Overview
The ZF 0501.223.076 OIL DIPSTICK is a precision-engineered measurement tool designed specifically for the WG92 and WG98 transmission series. This OEM genuine part allows operators to accurately verify fluid levels within the transmission sump, ensuring optimal lubrication and hydraulic pressure. Located on the side of the transmission housing, the dipstick provides a direct reading of oil condition and volume. The SKU 0501.223.076 is manufactured to ZF’s exacting tolerances, guaranteeing a secure seal and reliable readings even under high-vibration conditions. When paired with a properly sealed TRANSMISSION HOUSING, this dipstick prevents contamination ingress while enabling quick maintenance checks.
Symptoms of Failure
- Oil leaks around the dipstick tube: A worn or cracked dipstick seal allows transmission fluid to escape, leaving puddles under the vehicle and reducing overall fluid volume.
- Inaccurate fluid level readings: Degraded markings or a bent dipstick shaft cause false readings, leading to overfilling or underfilling that results in gear slipping or harsh shifting.
- Contaminated fluid ingress: A loose dipstick cap or broken O-ring lets dirt and moisture enter the transmission, accelerating wear on internal components like the HOUSING and valve body.
- Difficulty inserting or removing the dipstick: Warpage or corrosion on the dipstick shaft creates friction, making routine checks frustrating and risking damage to the guide tube.

Compatibility
This dipstick is engineered for ZF WG92 and WG98 series transmissions, commonly found in medium-duty trucks, buses, and construction equipment. It also fits select WG180 and WG200 models where the dipstick tube length matches the sump depth. For proper installation, ensure the CYLINDRICAL PIN aligns the dipstick with the guide bracket, and secure the assembly using a SCREW PLUG to prevent vibration loosening. Always verify your transmission’s serial number against ZF’s compatibility chart before ordering.
