Preparation
Remove power from the machine.
Belt removal
Use the belt tension mechanism to decrease the distance between the pulleys until
you have sufficient clearance.
and
show typical belt tension mechanisms.
Pulley removal
On the typical type of pulley and bushing shown in
, use the push-
off holes to remove the pulley easily. On special types of pulleys (example: large drive pulley
and cone), look at the parts document in the maintenance manual for more data. Some pulleys
are too heavy for only one person to hold.
Pulley installation
shows the typical pulley and bushing components. Make sure that
you keep run-out tolerances when you assemble and tighten the components.
Belt installation
Decrease the distance between the pulleys to put the belt on easily. Assemble
the components carefully. Make sure that the components are aligned. Adjust the belt tension
so the belt is tight.
Test
Before you connect power again, make sure that you remove all tools. Operate the ma-
chine with a full load. If the belts slip, increase belt tension with the machine shut down and
power removed. Then test again. Make sure that the machine is safe before you put it into reg-
ular operation.
