1. Carefully remove the Shrouds. Refer to the "Replace the
Shrouds" procedure in this manual.
2. Mark the position of the Belt Tensioner (A) on the Main Frame
bracket (D) to record the angle of the Tension Spring arm's position.
3. Slowly turn the Drive Pulley (B) backward and carefully ease
the Drive Belt (C) off the Drive Pulley to the outside.
Be sure to keep fingers clear of all pinch hazards as
you turn the Drive Pulley.
4. Using needlenose pliers, release the Tension Spring (A1) from
the hook (H) on the Main Frame.
5. Using 13 mm wrench and 6mm hex key, loosen and remove the
Belt Tensioner Hardware (E). Remove the Belt Tensioner assembly
(A) from the Main Frame and the Drive Belt (C). Discard the old Belt
Tensioner assembly.
6. Install the new Belt Tensioner assembly. Adjust the Belt
Tensioner position to the angle of the previous position recorded in
Step 2.
NOTICE: Do not overtighten the hardware (E). The Belt
Tensioner must be able to pivot. If the hardware is
too tight, this can cause wear on the bearings.
7. Put the Drive Belt (C) onto the Drive Pulley (B). Make sure the
Drive Belt is aligned on the Flywheel pulley (F), Belt Tensioner (A)
and Drive Pulley. Be sure that the upper portion of the Drive Belt is

(A1). Make sure that the belt tension is correct. Refer to the "Belt
Tension Adjustment" section in this manual.
