Function: Belt-driven CVT for compact FWD vehicles (torque capacity ~180Nm), optimized for fuel efficiency.

Key Features:

• Pushbelt System: Ultra-thin 12mm steel bands (reduced rotating mass)

• Hydraulic Control: Dual-range pulley pressure (40-90 bar adaptive)

• TCU Integration: Pre-programmed shift maps for 1.5L/1.6L engines

Failure Modes:

• Belt Slip: Low primary pressure (P17F1, often from valve body wear)

• Pulley Galling: Contaminated fluid damages cone surfaces

• TCU Communication Faults: CAN bus errors (U0101)

Critical Specs:

1. Fluid: Lifan CVT-EX1 only (3.8L capacity)

2. Pulley Alignment: Max 0.05mm runout

Pro Tip: Perform 500km gentle break-in – avoids premature belt seating issues.
