During our Open House yesterday, the belt on our older SP-15 slipped off the motor pulley. After the gig, we opened up the top and put the belt back on, but it looks like it may easily slip off again. This press has geared wheels at the motor and the drum roller, and the rubber belt has teeth in it (the other press has a v-shaped pulley system). The belt is smaller in width than the gear wheels. One side of the motor wheel has a guard that looks like it’s supposed to keep the belt from slipping off. But the guard is missing on the side closest to the motor. Should there be a guard there? Any other solutions to keep the belt in place? Will try to publish pics later today.
