Function: Critical component in CVT system, controlling gear ratio via adjustable primary/secondary pulley diameters.
Key Features:
Material: High-grade steel pulleys with hardened conical surfaces for belt/chain traction
Precision: Micron-level surface finish (Ra <0.2μm) to minimize belt wear
Hydraulic Actuation: Integrated piston channels for smooth ratio changes
Common Failure Modes:
Surface Pitting: Contaminated CVT fluid causes micro-abrasions → shudder (P17F0)
Bearing Wear: Leads to axial play (>0.1mm) causing belt misalignment
Seal Degradation: Results in pressure loss and ratio slip
Maintenance Criticals:
Use only Hyundai/Kia SP-IV CVT fluid
Replace both pulleys as a set to ensure proper belt tracking
Perform TCU reset after replacement for adaptive learning
