I need the righthand crank and pedal - Mongoose MGX Maxim Dual Suspension Mountain Bicycle

Pedals are NOT pressed on to crank arms.
The PEDAL is *screwed* onto the CRANK ARM (left pedal - reverse thread). The CRANK ARM is *pressed* onto the square, tapered CRANK SPINDLE with a bolt or nut. To remove a crank arm that is tightly mounted to the spindle requires a crank arm extractor, which a bike shop would have, or which can be purchased online.

you will need to obtain a spanner that firs the pedal nut which is sited between the pedal cage and the crank. That sextion should be machined and usually takes a spanner about nine sixteenths or five eights of an inch
You may to apply some force . Also note that the pedals may fit in the cranks on threads that go in different directions... the left hand crank may undo clockwise

Better replace the pedal and most probably the crank arm as well. Sometimes a new pedal can cut the threads true again on the crank arm but the crank arm may need replacement too, depending on the damage. Remember to fit the correct side pedal. The pedal threads differ between left and right and pedals are usually marked "L" or "R".

check the caliper fulcrum lever it sounds like it has siezed you may be able to free it off or you need a new one whichever always pump the brake pedal a few times before working handbrake otherwise the handbrake will be poor

Hi leftee44

This sounds like the crank arm, which can also be metal.

The crank arm links the pedals to the front derailleur and large cogs, which, in turn, turn the chain and rear derailleur and rear cogs attached to the rear wheel.

You may have to replace the pedal as well in case any damage was done to the thread of the pedal when it broke.

When attaching and screwing crank arms and pedals in place, care must be taken to turn left and right crank pedals in the correct opposing direction so as not to dethread the the crank or the pedal.

Crank arms and pedals are standard universal fittings on most bicycles and can be bought at most cycle and cycle accessories shops or website such as (click here):

I think I know what you are asking, but you haven't given me much to go on. Here are the names of the parts going from pedal to pedal -- pedal, crank arm, bottom bracket arbor, crank arm, pedal. Are you asking about attaching the crank arm to the bottom bracket arbor? And if so, are you missing the tapered pin that older bikes used to make this attachment? If so, the crank arm has 3 holes in it - one for the pedal, one for the bottom bracket arbor, one for the tapered pin. And your bottom bracket arbor will not have a square end, but will have a round end with a flat spot about 3/8 inches square. If you are missing this pin, then take the bike to a bike shop. It's a very inexpensive part, but might be hard to find the right size- or might require a little modification to fit. good luck Al K

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.

Hi Miranda

You need to purchase a pedal removal spanner(wrench). They are very thin so they can slot in between the pedal and the crank.

If this is not an option, find a 15mm spanner(wrench) and tap it onto the bit where the pedal meets the crank. Ive always found that you need a friend to sit on the bike, hold the opposite pedal at the low stroke while you undo the pedal.

**REMEMBER** pedals have the opposite to normal threads. To undo them, you need to turn them clockwise. Spray penetrating fluid onto the threads a day before you attempt to remove them. They are very difficult to remove.

Hope this helps.

you need to pull the pedal off on the side that the crank is on the pedal will thread off like a bolt but the threads are reverse on the pedal once you have the pedal off you will have to unscrew the two nuts that hold the crank in the frame of the bike the inner nut is easiest to get off with a flathead screw driver once you have those two out you can pull the crank out of the frame and then you may want to put it in a vice because the crank will turn off the pedal unit but you usually have to pry up on the crank a little to get the alignment pin out of the crank enough to turn it

Depending on left or right you will first need a crank puller to remove the crank in order to replace it. You will be better off taking it to a bicycle repair shop. Cranks usually only come in sets but the shop may have a spare or they might be able to order you a seperate one. The same applies for pedals. If the threads in the crank are not too damaged you might just need a new set of pedals or one replacement. Hope this helps.
