Overview
The ZF 4642.231.035 OIL LEVEL TUBE is a precision-engineered component designed specifically for the WG 150 series transmission. This genuine OEM part ensures accurate fluid level measurement within the transmission sump, directly supporting proper lubrication and cooling of internal gears and clutches. Installed as a vertical conduit within the transmission housing, the tube allows for reliable dipstick readings during routine maintenance. The SKU 4642.231.035 is manufactured to ZF’s exacting tolerances, guaranteeing a leak-free seal and long service life in heavy-duty industrial applications.
Symptoms of Failure
- Transmission fluid leaks around the dipstick area: A worn or cracked oil level tube often causes visible oil seepage at the top of the transmission housing, leading to low fluid levels and potential gear damage.
- Inaccurate oil level readings: When the tube becomes distorted or clogged, the dipstick may show incorrect fluid levels, resulting in overfilling or underfilling that causes gear slipping or overheating.
- Contaminated transmission fluid: A broken tube can allow dirt and debris to enter the sump, accelerating wear on internal components and reducing overall transmission efficiency.
- Increased operating noise from the gearbox: Insufficient lubrication due to a faulty tube often leads to whining or grinding sounds during gear engagement, especially under load.

Compatibility
This genuine ZF oil level tube is primarily designed for the WG 150 transmission series. It is also compatible with the WG 180 and WG 200 models, which share similar sump and housing configurations. When replacing this part, always verify that the TRANSMISSION HOUSING (4642101109) or the TRANSMISSION HOUSING (4642301205) is free from cracks or warping, as these can affect tube alignment. Additionally, ensure the TYPE PLATE (0730365125) is intact for proper identification, and inspect the GROOVED STUD (0631311009) for secure fastening during installation.
