HOW TO...REMOVE AND REPLACE THE REAR ROLLER ASSEMBLY
Tools Required: Phillips screwdriver, hex key wrench set
Step 1
Turn the power OFF at the ON/OFF switch and then unplug the unit from the electrical outlet.
Step 2
Remove the REAR END CAP PANEL (“See How To...”).
HELPFUL HINT: MARK THE POSITION OF THE REAR ROLLER ON THE INSIDE OF THE MOUNTING

Using a hex key wrench (1/4”), loosen and remove the TENSIONING BOLTS and WASHERS securing each side
of the REAR ROLLER MOUNTING BRACKETS. Alternate between each of the TENSIONING BOLTS rotating
each BOLT two (2) full turns at a time.
Step 4
Remove the worn REAR ROLLER from the machine.
Step 5
Position the new REAR ROLLER against the MOUNTING BRACKETS and reverse steps 1 through 3 to return all
parts to their proper locations.
Step 6
Refer to “How To...ADJUST AND TENSION THE STRIDING BELT” for proper STRIDING BELT tensioning
instructions.
NOTE: DRIVE BELT TENSION SHOULD BE BETWEEN 90 FOR EXISTING AND 100 FT/LBS FOR A NEW
DRIVE BELT. STRIDING BELT’S TENSION SHOULD BE .65% (IF GAUGES ARE AVAILABLE).
FOR STRIDING BELT TO BE CENTERED, THERE SHOULD BE 3 INCHES (75mm) ON EACH SIDE,
