I have a pedal (PD M770) stuck on a crank arm and I want to drill through the spindle so I can get it off the crank. I have tried using a HSS and a colbalt drill bit but I'm not getting anywhere. Any tips or ideas?
Thanks in advance.
Anyone? 🙂
dismantle the rest of the pedal - clamp it in a vice and turn the crank....
stupid stupid question but your going the right way yes ?
You were trying to turn it the right way, right?
EDIT: beaten to it.
Rather than drill the spindle, why not disassemble the pedal from the outboard end and put the bare axle in a vice?
EDIT: Doh too slow.
I'd try heating the pedal axle before I resorted to drilling AND MAKE SURE I WAS TURNING IT THE RIGHT WAY. 😯
Edit: Must type faster.
When originally trying to remove the pedal I was definitely turning the allen key in the correct direction. Where the allen key fits into the pedal have become rounded and the metal has split. I have dismantled the pedal but don't have access to a bench vice, hence why I've been trying to drill it out. Time to head to a local engineering shop me thinks.
Cheers folks.
if the allen key hole has rounded, use a pedal spanner on the flats on the other side.
what about... a spanner? or can one no longer use them on shimano pedals?
No spanner flats on XT or XTR (and possibly more)
Nor M540s, which are just XTs, without the XT moniker and a lower price tag.
not tried this on a pedal, but i once got a 40cm masonry drill bit well and truly stuck in a wall. I managed to get it out by grinding 2 flat areas with a dremel on the part the drill chuck fits on, then using a spanner on these.
If you've got access to a dremel or something similar you could try that?
Spindles aren't thick enough to grind usable flats onto IME, vice is the best shout.
Are the cranks worth it?
How about grinding/cutting the axle off, removing (slotting more and collapsing if nec) what's left? (8mm AK & therefore not too much metal left?
