Removal<br />
1. Disconnect the electrical ground<br />
wire from the battery.<br />
2. Place a flex-bar with a 15-mm<br />
socket on the automatic belt<br />
tensioner roller fastener as shown.<br />
Rotate the flex-bar as shown in<br />
the diagram to relieve belt tension.<br />
3. With the belt tensioner pressure<br />
relieved, remove the poly V-belt<br />
from the pulleys.<br />
NOTE: The tensioner can<br />
be temporarily blocked<br />
with a 0.16-0.2 inch (4-5<br />
mm) thick pin (bore). This<br />
facilitates removal and<br />
installation of the poly<br />
V-belt.<br />
4. After removing the belt, carefully<br />
allow the belt tensioner to spring<br />
back to the stop (if it had not been<br />
temporarily blocked).<br />
5. Inspect the pulleys for damage,<br />
rust, and grease deposits. Clean<br />
or replace as necessary.<br />
Installation<br />
1. Place the new poly V-belt over the<br />
pulleys, making certain the belt<br />
falls into all the belt pulley grooves.<br />
2. After installing the belt, carefully<br />
allow the belt tensioner to spring<br />
back to its normal position. If the<br />
tensioner had been temporarily<br />
blocked, relieve tensioner<br />
pressure enough to remove<br />
