CHAPTER 9: PART REPLACEMENT GUIDE
9.15 DRIVE BELT REPLACEMENT
1) Turn off power and disconnect the cord from the machine.
2) Remove the drive set as outlined in Section 9.10.
3) Loosen the belt tension nut (Figure A) and screw (Figure B) until there is enough slack in the drive belt to remove it (Figure C).
4) Use a straight edge to make sure that the pulley and encoder pulley are in a straight line (Figure D). If the belt is not on line, try to adjust the
pulley and encoder pulley. The belt is exonic, so belt tension is not critical.
5) Reverse Steps 1-4 to install a new drive belt. note: Torque the screw removed in Step 3 to 60 N-m.
6) Test the Climb Mill for function as outlined in Section 9.21.
