SPRING LOADED TENSIONER PULLEY (Cont’d)
Adjusting The Drive Belt
When adjusted correctly the spring loaded idler assembly
will increase the service life of the drive belt.
To adjust the spring loaded tensioner pulley, use the
following procedure:
Loosen the mounting bolt (Item 1) [A] on the idler bracket.
The pointer (Item 1) [B] will be at the seven o’clock
position when the belt tensioner is not under spring
pressure.
Pull the idler pulley against the drive belt, with the
adjusting nut (Item 2) [A], until the pointer is at the nine
o’clock position (Item 2) [B], lower the idler assembly a
small amount so that the idler is operating on spring
tension.
Tighten the mounting bolt (Item 1) [A] to 25–28 ft.–lbs.
(34–38 Nm) torque.
Run the engine for a few minutes. Stop the engine and
check the pointer position.
Adjust the idler assembly as needed.
After the spring loaded tensioner pulley has been in
service, readjust when the pointer reaches the seven
o’clock position.
