Maintenance
34
Note: If the new belt slips, examine the
pulley for wear. A good pulley will
have gaps between the flat parts of the
pulley and the belt (Fig. 34). If any of
the gaps are missing, the pulley is
worn out and the belt will not have
good contact on the sides and will slip.
If the pulley is worn out, remove the
two set screws and pulley, then replace
the pulley with a new one.
