Overview
The ZF 4657.354.041 OUTPUT GEAR is a critical component engineered for the WG171, WG190, and WG191 transmission series. This OEM genuine part functions as the final drive gear, transferring rotational force from the planetary gearset to the output shaft and ultimately to the vehicle’s driveline. Positioned at the rear of the transmission assembly, this gear ensures smooth torque delivery under heavy loads. The SKU 4657.354.041 is precision-machined to ZF’s exacting tolerances, making it essential for maintaining drivetrain integrity in industrial and commercial applications. When installed alongside the 4656101030: TRANSMISSION HOUSING, it forms a sealed, high-strength power transfer unit.
Symptoms of Failure
- Whining or grinding noise during acceleration: Worn gear teeth on the 4657.354.041 produce a distinct metallic sound, especially when shifting from neutral to drive. This is a common long-tail search query for “ZF output gear noise symptoms.”
- Transmission oil leaks near the rear seal: A damaged output gear can compromise the adjacent seal, leading to fluid seepage. Operators often search for “ZF WG171 oil leak rear output” when this occurs.
- Vibration at highway speeds: Uneven wear on the gear’s splines or bearing surfaces causes driveline shudder. This symptom is frequently queried as “ZF transmission vibration after gear replacement.”
- Intermittent gear slipping under load: The gear may lose engagement with the output shaft, causing power loss during uphill climbs or heavy towing.

Compatibility
This output gear is specifically designed for ZF’s WG-series transmissions, including the WG171, WG190, and WG191 models. It also fits the BP 210, WG 210, and WG 211 series due to shared output shaft dimensions. For proper installation, ensure the 4656301066: HOUS.FRONT SECT is aligned correctly. The gear interfaces directly with the 4656201015: SCREEN SHEET and the 4656301037: TUBE for oil flow regulation. Always verify your transmission model number before ordering.

Frequently Asked Questions
Q: Can the 4657.354.041 output gear be replaced without removing the entire transmission?
A: In most WG171 and WG190 applications, the output gear can be accessed by removing the rear housing cover and output flange. However, for WG191 models, partial transmission removal may be required due to space constraints.
Q: What torque specification should I use for the retaining nut on this gear?
A: ZF recommends 250 Nm (184 ft-lbs) for the output gear retaining nut. Always use a new lock washer and apply thread locker to prevent loosening under vibration.
Q: Is this part interchangeable between WG210 and WG211 series?
A: Yes, the 4657.354.041 is physically identical for both WG210 and WG211 transmissions. However, verify the output shaft spline count matches your specific unit before installation.
