Overview
The ZF 4616.201.048 OIL DIPSTICK is a precision-engineered fluid level indicator specifically designed for the WG 65 series transmission. This genuine OEM part provides accurate oil level readings, ensuring the hydraulic system maintains optimal lubrication and cooling pressure. Mounted directly into the TRANSMISSION HOUSING, the dipstick allows operators to quickly verify fluid condition without disassembly. The SKU 4616.201.048 is manufactured to ZF’s exacting tolerances, featuring a corrosion-resistant shaft and a clear, graduated marker for precise measurement 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 fluid level readings: A bent or degraded dipstick shaft provides false measurements, causing overfilling or underfilling that accelerates internal wear.
- Contaminated oil entering the transmission: A missing or broken dipstick cap permits dirt and moisture ingress, resulting in sludge buildup and reduced hydraulic pressure.
- Difficulty inserting or removing the dipstick: Warped plastic or damaged metal guides create resistance, often indicating the need for replacement alongside related fasteners like the HEXAGON SCREW.

Compatibility
This oil dipstick is engineered for the ZF WG 65 series, but its design principles extend to other WG-family transmissions requiring precise fluid monitoring. Compatible models include the WG180, WG200, WG210, and WG250 series, all of which share the same dipstick tube interface and housing geometry. For proper installation, ensure the HEXAGON SCREW and HEXAGON SCREW fasteners are torqued to factory specifications to prevent vibration loosening. Always verify your transmission’s serial number against the OEM parts catalog before ordering.
