ZF 4168.034.113 CONVERTER Torque Converter Assembly | Complete Unit

Overview

The ZF 4168.034.113 CONVERTER Torque Converter Assembly is a critical hydraulic component that transfers engine torque to the transmission input shaft through fluid coupling. Positioned between the engine flywheel and the transmission pump, this complete unit modulates power delivery while multiplying torque during low-speed operation. Designed as a direct replacement for the SKU 4168.034.113, this assembly ensures smooth engagement and efficient power transfer in heavy-duty ZF drivelines. The torque converter works in concert with the TRANSMISSION HOUSING to maintain proper alignment and fluid containment, while the HOUS.FRONT SECT and HOUSING REAR PART provide structural support for the entire assembly.

Symptoms of Failure

• Torque converter shudder or vibration during acceleration — Worn internal clutch friction material or damaged stator bearings cause noticeable shaking, especially when the converter locks up under load.
• Delayed or harsh gear engagement — A failing torque converter cannot build sufficient hydraulic pressure, leading to a pronounced lag when shifting from Park to Drive or Reverse.
• Transmission fluid overheating and dark discoloration — Slipping internal components generate excessive heat, causing the ATF to break down and appear burnt, often accompanied by a sulfur smell.
• Whining or grinding noise from the bell housing area — Worn needle bearings or a damaged impeller hub produce metallic sounds that intensify with engine RPM, indicating imminent converter failure.

Technical Specifications

Compatibility

This torque converter assembly is engineered for ZF WG and BP series transmissions used in construction, agricultural, and material handling equipment. It is directly compatible with the following transmission models: WG 180, WG 190, WG 200, WG 210, WG 211, BP 210, BP 215, BP 230, BP 235. The converter mates precisely with the TRANSMISSION HOUSING and is secured using a CYLINDRICAL PIN for accurate alignment during installation. Always verify your transmission serial number against the ZF parts catalog to ensure correct fitment.

Frequently Asked Questions

Q: Can the ZF 4168.034.113 torque converter be rebuilt, or must it be replaced as a complete unit?
A: While some internal components like the stator clutch or lockup friction disc can be serviced, the 4168.034.113 is typically replaced as a complete assembly due to the precision balancing required. Rebuilding without specialized ZF tooling often leads to vibration and premature failure.

Q: What transmission fluid is recommended for this torque converter?
A: ZF specifies a high-quality Dexron III or ZF LifeguardFluid 4 for the WG and BP series. Using incorrect fluid viscosity can cause the converter to slip or overheat, damaging the TRANSMISSION HOUSING and internal seals.

Q: How do I verify that the 4168.034.113 fits my ZF WG 210 transmission?
A: Check the transmission model tag located on the HOUSING REAR PART. The WG 210 uses a 340mm converter with a 10-spline input shaft. Measure the pilot diameter and bolt pattern to confirm compatibility before installation.
