Overview
The ZF 4642.231.060 OIL DIPSTICK is a precision-engineered fluid level indicator specifically designed for the WG 150 series transmission. This OEM genuine part provides accurate oil level readings, ensuring optimal lubrication and cooling within the transmission sump. Mounted directly into the transmission housing, the dipstick allows operators to quickly verify fluid condition and volume without disassembly. The SKU 4642.231.060 is manufactured to ZF’s exacting tolerances, making it a critical component for maintaining hydraulic pressure and preventing premature wear in heavy-duty industrial applications.
Symptoms of Failure
- Oil leaks around the dipstick tube – A worn or cracked dipstick seal can cause fluid to escape, leading to low oil levels and potential gear slipping under load.
- Inaccurate fluid level readings – If the dipstick markings become illegible or the rod bends, operators may overfill or underfill the transmission, causing overheating or erratic shifting.
- Contaminated oil ingress – A degraded dipstick cap or O-ring allows dirt and moisture into the transmission, accelerating internal component wear and reducing service life.
- Difficult insertion or removal – Warpage or corrosion on the dipstick shaft can make it hard to seat properly, risking damage to the TRANSMISSION HOUSING (part 4642101109) during routine checks.

Compatibility
This dipstick is primarily engineered for the ZF WG 150 series transmissions. Based on its design and mounting interface, it is also compatible with the WG 180 and WG 200 models that share the same sump depth and housing geometry. For proper fitment, always verify that the dipstick aligns with the TRANSMISSION HOUSING (part 4642301205) and that the TYPE PLATE (part 0730365125) confirms the transmission series. The dipstick is secured using a GROOVED STUD (part 0631311009) to prevent vibration loosening.
