Overview
The ZF 4657.374.044 SHAFT is a critical rotating component engineered for the WG190 and related ZF powershift transmission series. This OEM genuine part transmits torque from the input drive to the gear cluster, ensuring smooth power delivery under heavy industrial loads. As a precision-machined shaft, it interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain proper gear alignment. The SKU 4657.374.044 is your direct replacement for worn or damaged shafts in BP 210, BP 230, WG 190, WG 191, WG 210, WG 211, and WG 230 series transmissions.
Symptoms of Failure
When the ZF 4657.374.044 shaft begins to fail, operators typically notice gear slipping under load due to worn splines or bearing journals. A second common symptom is abnormal vibration or whining noise from the transmission housing, especially during acceleration. You may also observe metal debris in the transmission oil filter as the shaft surface spalls. Finally, difficulty engaging gears or a grinding sensation when shifting often points to this shaft requiring replacement.

Frequently Asked Questions
Q: How do I know if the 4657.374.044 shaft is the correct replacement for my WG190?
A: Check the transmission serial number plate on the housing. If your model is WG190, WG191, WG210, or WG230, this shaft is compatible. Also verify the spline count matches your existing shaft.
Q: Can I replace this shaft without removing the entire transmission?
A: In most cases, the transmission must be removed and disassembled to access the shaft. You will also need to replace seals and gaskets. We recommend replacing the CYLINDRICAL PIN and CAP SCREW during reassembly.
Q: What causes premature failure of this shaft?
A: Common causes include low oil level, contaminated oil, or misalignment of the HOUS.FRONT SECT. Regular oil changes and filter replacement (using SCREEN SHEET parts) can extend shaft life.
