ZF 4644.231.157 OIL DIPSTICK for WG200 | OEM Genuine Part

Overview

The ZF 4644.231.157 OIL DIPSTICK is a precision-engineered fluid level indicator designed exclusively for the WG200 series transmission. This OEM genuine part allows operators to verify oil volume and condition directly within the transmission sump, ensuring proper lubrication for planetary gear sets and hydraulic controls. The dipstick integrates into the fill tube assembly on the transmission housing, providing a sealed interface that prevents contamination ingress. The SKU 4644.231.157 is manufactured to ZF’s exacting tolerances, guaranteeing accurate readings and long service life in heavy-duty industrial applications.

Symptoms of Failure

• Transmission oil leaks around the dipstick tube: A worn or cracked dipstick seal allows fluid to escape, leading to low oil levels and potential gear slipping under load.
• Inaccurate oil level readings: Deformation or corrosion on the dipstick shaft causes false readings, resulting in overfilling or underfilling that accelerates internal wear.
• Contaminated transmission fluid: A broken dipstick cap or degraded O-ring permits dirt and moisture entry, causing sludge buildup and erratic shifting performance.
• Visible metal particles on the dipstick: When the dipstick surface deteriorates, it may shed debris into the oil, indicating advanced wear of internal components like the TRANSMISSION HOUSING.

Technical Specifications

Compatibility

This dipstick is engineered for ZF WG series transmissions, specifically the WG180, WG200, and WG210 models. It fits directly into the fill tube port on the HOUSING assembly. The part is also compatible with select off-highway and marine gearboxes that share the WG200 architecture. Always verify the TYPE PLATE on your transmission to confirm model designation before installation. For secure mounting, use the GROOVED STUD to fasten the dipstick tube to the housing.
