Monark Cycling - Recent Questions, Troubleshooting & Support
The steel on the crank arm of my Monark 817e exercise bike broke, how do i remove it, it has no cover/nut/bolt/washer holding it to the axel
It's very difficult to find someone familiar with a particular model of a particular brand of exercise bike, but I pulled up some pics that seem to show that yours can have one of two types of crank. One is called a "one-piece" crank. Typically it is removed by unscrewing parts from the left side after removing the left pedal (left-hand/reverse threads). You may have to remove the housing to access and remove the parts. The other is a 3-piece cranks, and the arm will have a plastic cover at the axle. If you remove that dust cap you will see a bolt underneath. One has to remove that bolt and then use a specialized tool (crank extractor) to remove the crank arm. Check with a bike shop (take in the unit or take some good pics) for replacement. I’m happy to help further over the phone at
