ZF 4168.028.353 CONVERTER Torque Converter Assembly | Complete Unit

Overview

The ZF 4168.028.353 CONVERTER Torque Converter Assembly is a critical hydraulic component responsible for transferring engine torque to the transmission input shaft in heavy-duty ZF WG 92 Series drivelines. This complete unit, identified by SKU 4168.028.353, sits between the engine flywheel and the transmission pump housing, utilizing a stator, turbine, and impeller to multiply torque during low-speed operation. As a sealed assembly, it directly influences shift quality and overall powertrain efficiency in construction and agricultural machinery.

Symptoms of Failure

• Torque converter shudder or vibration during acceleration: A worn stator clutch or damaged turbine fins causes noticeable shuddering when the converter locks up, especially under load.
• Transmission overheating and fluid darkening: Internal leakage across the converter seals generates excessive heat, leading to burnt-smelling, discolored ATF and potential damage to the 4660101023 TRANSMISSION HOUSING.
• Delayed or harsh engagement from Neutral to Drive: A failing torque converter fails to build adequate hydraulic pressure, resulting in sluggish takeoff or abrupt engagement.
• Loss of power under load or hill climbing: Slippage inside the converter prevents proper torque multiplication, causing the engine to rev without corresponding vehicle movement.

Technical Specifications

Compatibility

This torque converter assembly is engineered for ZF WG 92 Series transmissions, including the WG180, WG200, and WG210 models commonly found in wheel loaders, telehandlers, and industrial tractors. It directly replaces the original converter unit in these drivelines and interfaces with the 4660301058 HOUSING for proper alignment. For secure mounting, the assembly requires the 0631306174 CYLINDRICAL PIN to locate the converter to the flywheel, and the 0750100022 SCREW PLUG seals the hydraulic circuit during installation.
