ZF 4657.231.031 OIL LEVEL TUBE for WG190/WG210 | OEM Genuine Part

Overview

The ZF 4657.231.031 OIL LEVEL TUBE is a precision-engineered component designed specifically for the WG190 and WG210 series transmissions. This genuine OEM part serves as the critical conduit for monitoring and maintaining proper fluid levels within the transmission sump. Installed vertically within the transmission housing assembly, the tube provides accurate dipstick readings essential for preventing lubrication starvation or overfilling. The SKU 4657.231.031 is manufactured to ZF’s exacting tolerances, ensuring a leak-free seal and consistent oil level measurement throughout the component’s service life. This tube interfaces directly with the 4657101082: TRANSMISSION HOUSING and the 4657201166: HOUS.FRONT SECT to form a sealed oil circuit.

Symptoms of Failure

• External oil seepage at the tube base: A worn or cracked oil level tube often causes visible fluid drips around the transmission housing junction, leading to low oil levels and potential gear damage.
• Inaccurate dipstick readings: When the tube deforms or its internal bore becomes obstructed, the dipstick may show false oil levels, causing operators to overfill or underfill the transmission.
• Gear slipping under load: Insufficient lubrication from a leaking tube can cause intermittent gear engagement issues, particularly during heavy-duty operations or hill climbs.
• Transmission overheating: A compromised oil level tube disrupts proper fluid circulation, leading to elevated operating temperatures and accelerated wear on internal components like the 4657201170: HOUSING REAR PART.

Technical Specifications

Compatibility

Frequently Asked Questions

Q: How do I know if the 4657.231.031 oil level tube is failing?
A: Look for oil stains on the transmission housing near the tube base, inconsistent dipstick readings, or a persistent low-oil warning despite recent top-ups. A visual inspection for cracks or deformation is recommended during routine maintenance.

Q: Can I install this tube without removing the transmission?
A: Yes, in most cases the tube can be replaced in-vehicle by accessing the top of the transmission housing. However, if the tube is seized or the housing requires cleaning, partial removal of the HOUS.FRONT SECT may be necessary for proper access.

Q: Is the 4657.231.031 compatible with aftermarket dipsticks?
A: This OEM tube is calibrated specifically for ZF dipsticks. Using non-OEM dipsticks may result in inaccurate readings. We recommend pairing this tube with genuine ZF measurement tools for best results.
