In the transmission system, the ** pulley kit ** is usually associated with the ** continuously variable transmission (CVT) ** rather than the dual-clutch (DCT) or the traditional automatic transmission (AT). Its core function is to achieve stepless speed change through variable-diameter pulleys and steel belts (or chains), thereby optimizing power transmission efficiency and driving smoothness.

Application: Designed for Hyundai Mistra (DU) 1.8L gasoline engines with Start/Stop functionality. Key Features: Enhanced Belt Drive: High-strength push belt with widened pulley contact area for improved torque handling (up to 180Nm). Start/Stop Optimization: Reinforced auxiliary pump maintains hydraulic pressure during engine restarts. TCU Logic: Adaptive shift mapping for fuel economy and reduced belt slippage risk. Failure Modes: Belt Wear: Contaminated fluid (non-SP-IV)

Function: Seals the CVT assembly while supporting critical components (secondary pulley shaft, differential bearings). Key Features: Material: High-strength aluminum alloy (ADC12) with precision CNC-machined bearing bores Integrated Components: • Differential bearing races (must match OEM hardness)• Fluid return galleries (prevents oil starvation)• Speed sensor mounting points Failure Modes: Bearing Bore Wear: Causes shaft misalignment → belt/chain damage (P2817 code)
