E04 BUDDY 50 DRIVING PULLEY

The Genuine Buddy 50 driving pulley diagram shows the complete front CVT transmission assembly, including the variator, movable drive face, fixed drive face, roller weights, slider guides, ramp plate, variator boss, starter driven gear, kickstart ratchet components, springs, washers, and mounting hardware. This diagram is used to identify OEM replacement parts for CVT maintenance, variator servicing, and drivetrain performance repairs. The driving pulley assembly automatically adjusts gear ratios based on engine speed, helping deliver smooth acceleration and efficient power transfer. Common repairs include replacing worn roller weights that cause sluggish acceleration, servicing damaged slider guides or ramp plates that create inconsistent shifting, replacing a worn variator boss that causes excessive play, and restoring performance when the scooter experiences vibration, reduced top speed, or poor throttle response.
