ZF 4646.231.030 OIL DIPSTICK for WG250 | OEM Genuine Part

Overview

The ZF 4646.231.030 OIL DIPSTICK is a precision-engineered measurement tool specifically designed for the WG250 series transmission. This genuine OEM part provides accurate fluid level readings, ensuring your transmission operates within the optimal oil range. Located on the side of the main casing, the dipstick interfaces directly with the TRANSMISSION HOUSING to allow quick visual inspection of lubricant condition. The SKU 4646.231.030 is manufactured to ZF’s exacting tolerances, guaranteeing a perfect seal and reliable readings under high-vibration conditions common in 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 damage.
• Inaccurate fluid level readings causing gear slipping: When the dipstick markings fade or the rod bends, operators cannot verify proper oil volume, resulting in inadequate lubrication and clutch slippage.
• Contaminated oil entry through the dipstick port: A broken cap or degraded O-ring permits dirt and moisture to enter the transmission, accelerating wear on internal components like the HOUSING and valve body.
• Difficulty inserting or removing the dipstick: Bent shafts or deformed handles indicate the part has fatigued, risking breakage inside the fill tube.

Technical Specifications

Compatibility

This dipstick is primarily engineered for the ZF WG250 transmission series. It also fits the WG180, WG200, and WG210 models when used with the appropriate COVER and mounting hardware. For installations requiring secure fastening, pair this dipstick with a HEXAGON SCREW to ensure vibration resistance. Always verify your transmission’s serial number against ZF’s compatibility charts before installation.
