DRIVE SYSTEMS

BELT DRIVE SYSTEM TROUBLESHOOTING CHART

Powerlite And 20” CCR Rotor Drive

The rotor drive systems used on the 20” CCR’s and

Powerlite are merely modified forms of the system

used on The Snowmaster, S-200 and S-620. Some

use a spring loaded idler system and others connect a

cable to the idler to engage and disengage the belt.

The Powerlite models built in 1998 and older use the

spring loaded idler system. The spring loaded idler

maintains tension on the belt for constant drive (Figure

83).
