Crankset Revisited or This Could Get Expensive!

Armed with reader tips, last night the Planner Guy, turned Bike Shop Guy, took the wrench to the crankset of my Eco 3 one more time.  Had we indeed put the right pedal on the left crank shaft??  The left on the right?? 


And the answer is . . . . nope.  (Heavy sigh!)  The pedals were on the correct crank shafts.  The left unscrewed off the crank shaft easily, and Bob reattached it with no trouble.  Not so much with the right pedal, however.  And yes, Bob did work the wrench but I DID steady the bike!


The threads on the right pedal appeared to be in good condition but the ones in the right crank shaft appear were torn.  Bob passed me the remnant of one, pictured below.  After struggling to reattach it (screwing it back on from left to right . . . . ), his efforts proved fruitless.  "I think you need to take this to the bike shop on Saturday," he sighed.


And so it goes.  I'm taking the floppy, little dog to the groomer tomorrow morning for a long needed haircut so I'll stop by Single Track afterward and see what they have to say.  I hope for a solution that does not involve waiting for weeks for replacement components or a bill over $100.

Thats a drag!! I hope the solution is inexpensive and that you are back to pedalling on your new steed soon.

The threads of the crank can be "cleaned up" by running a tap or thread chaser through it in most cases. If you don't have a tap, running the other pedal through from the back side could do the job. Be gentle though and do this a little, back off, then a little more, repeat. This is only if one thread is buggered, not the whole lot. Then it is at least good enough to get the pedal started and run in true and straight. If the pedal will not tighten (it should) and or stay in place, some epoxy can be coated on the threads first then run it on home. This should prevent you from buying a new crank. The only issue would be a problem of removing that pedal sometime down the road if you should ever have to.

I thought about this later, try some Loctite thread locker on the threads before going the epoxy route. That should do the job.

Took the Dahon down to Single Track yesterday and they have it repaired, apparently w/out a new crankset. Yippy! Am anxious to see what the solution was. I received many hopeful suggestions so I'll be interested to see, which one was closest to the one they found.

Hooray! Glad you were able to find a simple, (hopefully!) inexpensive solution!

Might have 'crossed threading' on the first assembly.

Eh, I'm in exactly the same situation. The left Suntour PL-NX70 has broken after 1000 km. I could easily replace the left one, but the right one's thread is so worn. I had a metal shard as well.
