This document provides an agenda for a training on the V-matic belt automatic transmission. It will cover the V-matic mechanism, inspection and repair training, and transmission ratio characteristics. Videos will be played demonstrating the V-matic mechanism, its operation, drive belt inspection for different engine sizes, and clutch disassembly and assembly. The training will include hands-on practice of disassembling and assembling the V-matic. Charts are included comparing speed-torque characteristics of manual transmission, V-matic transmission under various throttle conditions, and how it automatically shifts gears during acceleration and cruising.

7. Drive pulley assembly
Centrifugal force
Low speed High speed

8. Driven pulley assembly

11. Centrifugal clutch
It is dry type.
Theory and mechanism are the same as Dream. Wave. etc.
But motorcycle and cub is wet type.

12. Drive force is transmitted
by Friction force
For small engine
(from 50cc to 125cc)
For big engine (over 250cc)
Measure up the width
