ZF 4168.034.124 CONVERTER Torque Converter Assembly | Complete Unit

Overview

The ZF 4168.034.124 CONVERTER Torque Converter Assembly is a complete, factory-matched unit engineered for the demanding power flow within ZF WG-series automatic transmissions. This precision component sits between the engine flywheel and the transmission’s oil pump, converting rotational torque into hydraulic energy to drive the planetary gear sets. The SKU 4168.034.124 is a direct replacement for worn or failed converters, ensuring that lock-up clutch engagement and fluid coupling remain within factory tolerances. When paired with a robust TRANSMISSION HOUSING, this assembly maintains proper alignment and prevents premature bushing wear.

Symptoms of Failure

• Shudder or vibration during lock-up: A failing torque converter often causes a noticeable shudder when the clutch engages, especially under light throttle at highway speeds.
• Transmission fluid overheating: Worn internal stator bearings or a slipping converter can generate excessive heat, leading to burnt-smelling fluid and dashboard warning lights.
• Delayed or harsh engagement: When the converter fails to build adequate hydraulic pressure, you may experience a lag when shifting from Park to Drive or Reverse, followed by a jarring clunk.
• Torque converter drain-back noise: A whining or grinding sound that persists even after the vehicle is stationary often indicates worn thrust washers or a damaged impeller hub.

Technical Specifications

Compatibility

This torque converter assembly is designed for ZF WG-series transmissions, specifically the WG 180, WG 190, WG 191, WG 200, WG 210, WG 211, and WG 230 models. It is a direct fit for both on-highway and off-highway applications where the original converter has been removed. For proper installation, ensure the transmission’s HOUS.FRONT SECT is clean and free of debris, and verify that the HOUSING REAR PART aligns correctly with the converter pilot. Always replace the CYLINDRICAL PIN during reassembly to ensure precise dowel alignment between the converter and the flexplate.

Frequently Asked Questions

Q: Can I install the 4168.034.124 converter without removing the transmission from the vehicle?
A: In most applications, the transmission must be removed to access the converter bolts and flexplate. We recommend a full bench rebuild to inspect the HOUS.FRONT SECT and pump bushing simultaneously.

Q: How do I know if my torque converter is the correct model for a WG 210 series?
A: Verify the part number stamped on the converter hub matches 4168.034.124. Also check that the pilot diameter aligns with the HOUSING REAR PART pilot bore. If in doubt, measure the original converter’s overall height and bolt pattern.

Q: What other seals should I replace when swapping this converter?
A: Always replace the front pump seal, the converter hub seal, and the CYLINDRICAL PIN to prevent fluid leaks and misalignment. Inspect the TRANSMISSION HOUSING for cracks or wear at the dowel holes.
