tools And eqUiPMent reqUired
1. 24 mm Socket / Ratchet.
2. Matrix Wheel Puller.
3. Torque Wrench to 2000kgf*cm/196 N-m (145 ft*lbf).
4. #2 Phillips Head Screwdriver.
5. 5 mm, 6 mm, and 8 mm Allen / Hex.
6. 13 mm / 17 mm Open End Wrench.
7. Pliers.
8. Side Cutter.
ProcedUre
1. Read these directions all the way through before proceeding.
2. Follow the procedure outlined in Section 8..1 of the Ascent
Trainer Service Manual to remove the right side disc from the
machine.
3. Loosen the belt tension lock nut with a 17mm wrench, and back
off the screw so that the drive belt can be removed from the unit.
Remove the locking nut to allow more room to fit the parts in later
steps.
4. Use a 5 mm Allen wrench to remove the tensioner from the
machine. NOTE: Several of the Phillips screws will need to be
removed so the plastic covers can be spread far enough to remove
the tensioner completely from the mounting post.
5. If required, remove the non-crowned tension roller from the old
assembly and move it to the new assembly. Rollers that have a
crowned face or rollers consisting of two bare ball bearings are to be
replaced with the new roller kit.
6. Check the 5 screws on the tensioner assembly. They should be
only lightly finger tight and the three pieces should all slide freely
against each other without excessive slop.
7. Place the alignment block over the small pulley and then place
the new tensioner onto the frame.
8. Apply pressure across the small pulley and the roller to bring the
two parts into contact with the alignment block.
