Can I bodge it ?

[KirstinS]

So I made an idiotic schoolboy error and put my new pedals onto my gsm kit the wrong way round.

Result - stripped threads on crank arm. and pedal

A quick callto woosh and new arms on their way for a frankly incredible 14 quid inc p and p. Thanks to Andy and co as ever

But is there a way I can bodge the ruined pedals to the cranks?

I tried 2 pack epoxy, lasted a mile

I tried expoxy metal putty, lasted 3miles

Any other options excluding welding or helicoils ?

Come on, I'm sure someone knows some proper gluey stuff !.

Thanks as ever folks

Top marks for a solution!

But I can not buy before new cranks arrive

And, crucially, it is 50% more expensive than a new set of cranks!

I also found this online....but have you actually got personal experience ? I'm sceptical it isn't just marketed expoxy

 

[soundwave]

i doubt anything will hold it for very long tbh, best cheapest option is to get someone to weld them.

or just wait for the new ones

Cheapest and best is those new cranks plus buying new pedals Highpath can repair your existing cranks by fitting inserts, but even that costs £45 for the pair and you'd still have to buy the pedals.

So basically there ain't no glue strong enough?

You should really have added the adverb 'successfully' following 'bodge' but by now, you will have probably gathered that there are several ways you can 'bodge' the job, none of which is likely to prove satisfactory in the longer term.

Metalworking solutions are possible but unless you have a friend with the necessary tools and equipment, the cost would be disproportionate, ergo pointless.

If it was only a glueing job between perfect surfaces, there is.

But in this sort of case the glue/cement is also having to act as a filler, and it's not strong enough to withstand leg strength pressure without compressing and therefore loosening the bond.

Being curious, what I would like to know is how you managed to get a LH threaded stud into a RH threaded hole. Did you use that essential tool, a 4lb "spanner"?

Time-sert is the way to go for a permanent repair...flecc's £45 is too much to pay, go to your local motorbike shop or even garage and they should be able to do two of them while you wait for half the price...pity you're not up this way Kirstin as I've got a set, mines metric but the inserts are only about a quid each!

A fair question !

Well, in truth it was getting over excited at Xmas with my shiny new pedals......and doing the job whilst full of Beavertown Gamma Ray pale ale [emoji481]
Lesson learnt!

I always put plenty of grease on the pedal threads and screw them on with fingers until they are fully in place before doing them up with spanner. That seems to have saved me from cross threading them by accident.

Lubricating the threads .........rather than lubricating myself

Probably a good idea !

Blimey, glad I didn't come out with that statement - there may have been some comments!!!

"Special" lubricant to go with the lycra shorts . Speak to Benjahmin about. He's looking for tips.

If you have a set of taps you could drill and thread the center of the stripped pedal and fit a bolt with a washer to hold the crank from the frame side of the crank arm.
Personally any bodge in this area is to dangerous in case it lets go when you are applying a lot of power or standing, says the person who shortened a set of cranks by cutting and bronzing them back together

Exactly what I was going to say. Drill,tap,bolt and washer.
