Use a flat screwdriver to unseat the tabs that hold the front top cover in place. This will expose the flywheel and pedal arm connection points. Rotate the flywheel by hand and determine whether lubrication will accomplish the repairs. If the bearings are exposed, use a grease gun with an extension nozzle and lubricate both bearings with lithium grease. If the bearings are damaged or sealed, proceed to the next step.
Remove the front and side covers on the main frame. Hold the flywheel with one hand and use a box wrench to loosen the bolts that secure the pedal arms at each side of the flywheel. Pull the arms away from the flywheel and remove the bearings from each side.
Test the bearings as before. Lubricate exposed bearings with lithium grease and reinstall them. Sealed bearings must be replaced. Reattach the pedal arms to the flywheel. Replace the main frame covers and front top cover to complete the repairs.
