What screw do I need for the crank arm because it keeps popping a loose when I pedal on it for too long or too fast


It is no good buying a bolt from Home Depot. You need to visit a bike shop. The bolt is wedge shaped, the tighter you turn it the more it locks the crank to the shaft.

Pedal assembly for a trek navigator 100


This bike had a square-taper bottom bracket. What happens with this type is that the bolts holding them on become slightly loose over time. The crank arm begins to wobble and the "wollows" out the inner hole on the crank arm such that a new one will have to be purchased. They are about $15.

The only parts envolved are the cranl arm and the both that holds it in place.

This bike looks to be of the Lemond Revmaster series.

first, dial the resistance knob back until the leather break pad is no longer touching the flywheel. Get down on the floor and postion yourself between the flywheel and pedal cranks. Slowly turn the cranks arms and listen and feel for a roughness in the bike.

This has bike has bearings and a belt. It should not make any noise.



Now with the right pedal at a 2:00 position tighten the resistance knob down all the way so the flywheel will not turn. Then get on and push very hard on the right pedal. If the belt is loose, the pedal will move. Austin Fitness Rentals Rent Commercial grade Fitness Equipment in... ">

follow this steps and fix it. God bless you

1

Prepare to oil by filling a grease gun with lithium grease. Check your owner's manual for the exact type of grease for your unit.

2

Locate where it is you need to lubricate. Focus on the bearings, free-moving joints and attachments with moving parts such as handle bars, wheels, pedals arms and guide rails. Go to each location one by one when greasing.

3

Unfasten the bolts or screws that hold the joint or attachment that you wish to lubricate.

4

Grease each bolt and screw liberally. Tighten each bolt and screw back into its place when finished.

5

Wipe away any excess grease
Loose Pedals

1

Kneel next to the left side of the elliptical's base. Use the Phillips screwdriver to tighten the two screws located in the center of the left pedal.

2

Use the Allen wrench to remove the bolt securing the left pedal arm to the pedal leg and body arm. Use the Phillips screwdriver to remove the screw securing the rear end of the pedal leg to the crank arm.

3

Pull the end of the pedal leg free of the crank arm. Wipe the crank arm clean, then apply a fresh coating of machine grease or silicone lubricant. Replace the end of the pedal leg back onto the crank arm and use the previously removed screw to secure it back into place.

4

Join the front end of the left pedal arm to the ends of the pedal leg and body arm. Use the previously removed bolt to connect the pieces together.

5

Move to the right side of the elliptical and repeat the above steps on the right pedal arm

My Father has a schwinn Airdyne. the pedal was loose, I bought a new piece that fits through the pedal, replaced it but it is still loose. I think the medal in the crank wheel is worn...... Because the...


There is a metal shim needed in the bike/pedal that has to be tapped in to keep the pedal tight. If you dad has used the bike for several hundred miles and/or his feet might actually bend the pedals over time (weight), it is possible the metal piece that the pedal attaches to could become bent slightly, and I have seen a few bikes, that need to be taken to the bike repair store (call a large bicycle/itness store) that has a good repair shop and they often can repair these, but rarely less than $125 for an Airdyne repair/tuneup.

I have a jamis cross country 2.0 bike. the bottom bracket creaks. not sure why.


One or both of your crank arms are probably loose. Try pulling and pushing (pretty hard) on the pedal end of the crank arm (toward the bike and away from the bike) If it's loose, it will be apparent. The arbor of the bottom bracket is usually square on the ends, and this is tapered (the square is bigger closest to the bike) You just need the right size wrench to tighten the nut that holds the crank arm onto the bottom bracket arbor.

Left pedal broke can i get replacement?


All depends on if you stripped the crank arm, you may have to replace your crank arm if you rode with a loose pedal. Pedals are sold in pairs, and there are 2 sizes, a one piece crank is 1/2" and 3 piece crank is 9/16", take your bike to the bike shop and they will tell you if you need a new crank arm or not. It will do no good to just replace your pedal if there is a bad crank arm thread, it will not hold.

Bad crank bearings can move crank arms small amount.


That would depend on the style of bearings (loose ball or caged balls vs sealed bearings) and possible bottom bracket damage.

Either way, a Bike Shop mechanic would probably need to assess it for you. Special tools are usually involved.

I have an stationary bike, the left pedal keep getting loose i tighten it but it get loose anyway


Check to see if the threads (spiral edges) on the pedal stud or the crank arm is worn down. If they are, then you will need to replace one or both.

Hope this helps.
