Trouble removing pedals and crankset

[Ming the Merciless]

Now don't forget the grease when refitting the pedals.

removing them on the bike was a non starter. The force needed meant it was not possible to hold the bike. I tried against a wall but was putting too much stain on the forks/headset.

In order to achieve the 'instantaneous' moment/force one needs to support the bottom bracket with a solid item (otherwise the tyres cushion the effort). Why do you think the stain (sic) on the forks (sic - it's a fork) and/or headset would be too much? They're designed to cope with such forces for their day job.

the problem with "inside" tool contact screw heads (like hexagon & allen keys) is
1) the small inside surface that has to pass the tools force,
2) the small momentum the tools force has on the turning axis (due to the small distance from the center) and
3) the larger outside surface that sits close, or makes contact with, the material on which has to be mounted.
I think there isn't any alternative than hexagon due to the small available area.
So, it's all about prevention. I put the same oil as my chain on thread of typical problematic mounts (automotive oil, because it was cheap). Since, I didn't have hard times anymore when having to replace a pedal. The days of putting the bicycle against the wall under the window then jump on the big key are gone.

I bow to your superior knowledge and thank you for the corrections to the grammar. I would add that it had been to a LBS who couldn't get them off

Have you got the pedals and crank set off yet?

Thanks for helping out a novice. Getting a proper spanner and teaming it with judicious use of a hammer was definitely the way to go.

Sounds like he/she did.

Yes. All sorted. I might have been up until 1am panicking and tweaking bits to get it all to run smoothly before my ferry to Belgium the next day, but hey....working under pressure brings out the best in me!

Cheers.

Since watching this video I have never had a problem. Always turn the spanner towards the back of the bike (from above).

Worse case scenario would be to use a cheater bar on the end of the spanner.
