6. The crankarm removed from the right hand side has a magnet in a recess on the lower

backside of the crankarm. The magnet is held in the crankarm by it’s magnetism. Remove

the magnet either by prying it out with a thin bladed screwdriver or by placing a heavy piece

of steel near the magnet and allowing the it to adhere to the heavy piece of steel.

Replacing a Crank Arm Assembly

7. Place the magnet removed in step 6 in the crankarm that will be mounted on the right hand

side of the EFX.

8. Clean the crankarm mounting bolt threads and the input pulley shaft threads with an alcohol

swab. Allow them to dry and apply blue loctite to the crankarm mounting bolt threads.

9. Position the crankarm on the input pulley shaft. Thread and hand tighten the 14 mm.

crankarm mounting bolt into the input pulley shaft. Torque the nut to 300 in/lbs.

10. Replace the stairarm assembly as described in Procedure 7.24.

11. If you are replacing both crankarm assemblies, repeat steps 8 and 9 for the second

crankarm assembly.

12. Set the on/off switch in the “on” position. Use the unit and note whether the stride rate is

being displayed. If the stride rate is zero while the unit is being used, the magnet was

installed backwards. The hall effect sensor is polarity sensitive, therefore the magnet

installed in step 7 must be reversed.

13. If the stride rate in step 11 was zero, remove the magnet from the right hand crankarm,

reverse and reinstall it. Repeat step 11.

14. Set the unit at it’s highest resistance setting and use the EFX for a minimum of 3 minutes.

Stride in a forward direction for half of the time and in a backward direction for half of the

time. Set the on/off switch in the “off” position and re-torque both of the 14 mm. crankarm

mounting bolts to 300in/lbs.

15. Replace the rear cover per Procedure 7.1.
