How to loosen the crank nut - figure 17 - exercise equipment 831285870 Proform Proform rebel


Thanks for contacting I understand how frustrating it is having trouble with removing the slotted crank nut off the exercise bike. We are here to help. The tool that is used to remove the slotted crank nut are, a slotted crank nut tool and crank dustcap pin tool. Those two tools would make removing the crank nuts much easier. The price of a service call on exercise equipment is about $96.00. I hope this helps.

The console on my Pro-Form Rebel Recumbent Bike Elliptical Trainer model 831.285870 is not displaying data. What can be wrong?


You either have a broken or disconnected wire from the console to the reed switch, a defective reed switch, or a defective console.

I am sending you an image with instructions for diagnosing this problem.
