Is there a way to repair a stripped pedal mount on a bicycle crank arm? Or do I need to replace the crank arm? |
It is the right side crank arm. I've tried to remove it but I don't know how. I removed the dust cap and nut, but it won't budge. If I can just repair the pedal mount somehow that might be easier. If your pedal mount is stripped out, then you will have to replace it. Even if the pedal still threads into the crank, any loosness will quickly cause the pedal/crank connection to fail. You can purchase inexpensive single crank arms from a shop- many times shops will have old parts, and if you're not too picky, they can provide one for you without too much trouble. They may have to order one, but even then, it should not be too expensive if you don't need the "latest and greatest" model. The shop can check the crank arm size and type for you (there are different lengths and mount types for cranks) so it's best to simply bring it into a shop. If a shop is not available, check on the inside of the crank arm for a size printed there: common sizes are 170, 172.5 and 175. Likely it's one of these numbers. Next, check to see what type of crank mount you have: if it is a "taper spindle" type, the bottom bracket axle that the crank mounts on will be square. If it's a notched-type, then you have a slightly more contemporary splined bottom bracket. Good luck! Source(s): Worked in bike shops for years To remove the crank arm, you need the correct tool (like a crankarm puller). For the stripped out mount, you are better off replacing the crank(s). If you try to retap the hole, then the pedals won't screw in properly. It is worth buying new crankset. Sounds like a good time to upgrade too! Try FSA carbon cranks. But, since it is such a cheap bike, upgrade the whole thing. Ride safe! Try contacting Iron Horse they may actually send you a new set of cranks for a little or no charge> http://www.ironhorsebikes.com/makecontac... heres the corporate info also> Iron Horse Bicycles, LLC 85M Hoffman Lane Islandia, NY USA 11749 Phone: 1.631.232.9259 Fax: 1.631-232-9370 Ouch. Yeah, you could try to retap it but it's not likely to work out well unless you throw more moeny at it... at which point you're back to the cost of buying new. Like the previous poster mentioned, you'll need a crank extraction tool to get the old one off. For help, you can try: http://www.sheldonbrown.com/tooltips/cot... While a bit old, most of the info here is still quite releavent. As for a new crank, Truvative 5D is a good deal, and very stout. There are countless used cranks out there as well in the usul places that can be had for under $40... Heck, the Nashbar model is now $20! And the Shimano Deore is $40 See: http://www.nashbar.com/results.cfm?categ... As for the size, if you replace both arms you'll be OK, and make sure you get the old threads from the crank off of the pedal, And make sure you grease the threads before you put them in the new crank. |
