Overview
The ZF 4657.374.053 SHAFT is a critical rotating component engineered specifically for the WG190 and WG210 series transmissions. This OEM genuine part transmits torque from the input assembly to the planetary gear sets, ensuring smooth power delivery under heavy industrial loads. Positioned within the main gear train, the shaft interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain precise alignment. The SKU 4657.374.053 is manufactured to ZF’s original tolerances, making it a direct replacement for worn units without requiring housing modifications.
Symptoms of Failure
- Transmission gear slipping under load: When the shaft splines wear, the gear engagement becomes inconsistent, causing intermittent power loss during acceleration or uphill operation.
- Metallic grinding noise from the bell housing: A worn 4657.374.053 shaft allows radial play, leading to metal-on-metal contact between the shaft and the HOUSING REAR PART.
- Oil leaks near the output flange: Excessive shaft vibration degrades the lip seal, resulting in visible fluid drips beneath the transmission.
- Hard shifting between forward and reverse: A bent or fatigued shaft creates binding in the clutch packs, requiring excessive force to engage gears.

Frequently Asked Questions
Q: Can the 4657.374.053 shaft be used in a ZF WG210 with a modified housing?
A: Yes, but only if the HOUS.FRONT SECT and HOUSING REAR PART are OEM-spec. Non-standard bores may cause premature spline wear.
Q: What torque specification is required for the shaft retaining hardware?
A: Use 85 Nm (63 ft-lbs) for the CAP SCREW and 45 Nm (33 ft-lbs) for the FIXING PLATE bolts. Always replace the SCREEN SHEET during reassembly.
Q: How do I identify a counterfeit 4657.374.053 shaft?
A: Genuine parts have a laser-etched ZF logo and a matte finish. Counterfeits often lack the hardened spline root and may have visible grinding marks near the CYLINDRICAL PIN hole.
