Overview
The ZF 4657.231.004 OIL DIPSTICK is a precision-engineered component designed specifically for the WG190 and WG210 series transmissions. This OEM genuine part allows operators and technicians to accurately measure transmission fluid levels, ensuring optimal lubrication and hydraulic pressure within the gearbox. Mounted directly into the transmission housing, the dipstick provides a reliable visual reference for oil condition and volume. The SKU 4657.231.004 is manufactured to ZF’s exacting tolerances, guaranteeing a perfect seal and consistent readings over the life of the unit.
Symptoms of Failure
- Transmission fluid leaks around the dipstick tube: A worn or cracked dipstick seal can cause oil to weep from the insertion point, leading to low fluid levels and potential gear slipping.
- Inaccurate or hard-to-read oil level markings: Over time, the markings on the dipstick can fade or corrode, making it difficult to determine the correct fluid level and risking under- or over-filling.
- Contaminated oil readings due to degraded material: If the dipstick shaft becomes brittle or pitted, it can introduce debris into the transmission sump, accelerating wear on internal components.
- Difficulty inserting or removing the dipstick: A bent or warped dipstick handle can cause binding, leading to improper seating and eventual seal failure.

Compatibility
This dipstick is engineered for ZF’s WG series powershift transmissions. It is a direct fit for the WG190 and WG210 series, and is also compatible with the WG180 and WG200 models when used with the correct tube assembly. Always verify the part number against your transmission’s serial plate before installation.
Installation Notes
When replacing the dipstick, inspect the mating surfaces on the 4657101033: TRANSMISSION HOUSING for damage or debris. The dipstick tube interfaces with the 4657201027: HOUS.FRONT SECT and the 4657201012: HOUSING REAR PART to ensure proper alignment. Secure the assembly using a 0631306792: CYLINDRICAL PIN to lock the dipstick in place, preventing vibration-induced loosening.

Frequently Asked Questions
Q: How do I know if the 4657.231.004 dipstick is the correct part for my WG210 transmission?
A: Verify the transmission model plate on the housing. The WG210 uses a specific tube length; this dipstick is calibrated for that series. If you have a WG180 or WG200, measure the tube depth before ordering.
Q: Can I replace just the dipstick seal without replacing the entire dipstick?
A: The seal is integrated into the dipstick handle. ZF does not offer a separate seal kit for this part. For a leak-free fit, we recommend replacing the complete 4657.231.004 assembly.
Q: What torque should I use when securing the dipstick tube?
A: Tighten the retaining bolt to 25 Nm. Over-torquing can distort the HOUS.FRONT SECT and cause misalignment.
