How to Overhaul the bike pedals ?
Posted on: June 20, 2011
Pedals depend on internal bearings to spin smoothly. Over time, the bearings wear out causing the pedals to spin less smoothly, which reduces performance. This section describes some steps you can take to overhaul the pedals. For cheaper pedals, overhauling isn't an option, because they're made too cheaply to be serviceable. For higher-quality pedals, an overhaul is a good way to extend their life.
As you take apart the pedal, place each component on a clean flat surface in the order it was removed. This will help you reinstall the components in the correct order.
Here's how to overhaul your pedals:
1. If the pedal has a flat medal cage, remove it before beginning to overhaul the pedals. This will make working with the pedal easier. There should be several screws holding it in place, which can be removed with a screwdriver or Allen wrench.
2. Remove the dust cap with a small flathead screwdriver. Be careful not to damage the dust cap.
3. Loosen the locknut under the dust cap, holding everything in place. To reach the locknut, you may be need to use a socket wrench.
4. If there is a washer in place, remove it. If the washer is difficult to lift out, use a flathead screwdriver or needlenose pliers.
5. Remove the cone that is holding the bearings in place. The cone may lift out or need to be unthreaded with a screwdriver or needle-nose pliers. Make sure you're supporting the axle. If the axle drops out, the bearings will fall out and you'll be searching for them on the floor for hours.
6. Scoop out all the bearings and inspect their surfaces. If they're dull and have dents, they need to be replaced.
7. Clean all the parts, and then install them in reverse order from how you disassembled them. Be sure to apply a liberal coat of grease inside each side of the pedal. This will help hold the bearings in place until you thread the cone, washer, and locknut back on.
8. Finish the reassembly by refitting the dust cap. This is important to keep dirt and water out of bearings and ensure that your overhaul lasts.
