ZF 4168030263 Torque Converter Assembly

The ZF 4168030263 torque converter is a hydrodynamic coupling device designed for ZF 4WG160 powershift transmissions. It functions as the primary launch device and torque multiplier between the engine and transmission gearbox. The assembly consists of a pump wheel (impeller), turbine wheel, and stator wheel housed within a welded steel casing. It is engineered to withstand high thermal loads and shock loads typical in heavy construction equipment cycles. This unit serves as a direct replacement for Hyundai wheel loader models HL740-9, HL740-9S, HL935, HL940, and HL940TM equipped with the ZF 4WG160 transmission. It also cross-references to Case wheel loader models 521E through 521G. The converter utilizes precision-balanced components to minimize vibration and ensure efficient power transfer across the operating speed range. Installation requires verification of transmission model and converter spline count against the original equipment bill of materials.
