Seized Pedal

godtabh

Was looking to set up my second bike while i'm not using it for my wife.

She doesnt have any clip on shoes so was gona put the original pedals on but cant seem to get them off.

Nearly broke the Aldi wrench trying to take it off this evening.

Tried some of that Aldi 85 stuff but no luck. Gona leave it over night and see if it works tomorrow.

Any one have any tips?

Left Hand Pedal has left hand thread.....

Can be really hard sometimes particularly if you haven't used anti-seize on the threads when you were fitting them? Hope I'm not being smart but you know that one of the pedals loosens clockwise?

Assuming you know about the reverse thread.

Technique is just as important as brute force. Which side is the seized pedal on?

Also, do you know who put the pedals on? Any chance they are cross-threaded?

I've had a couple of run ins with seemingly immovable pedals in the past too. Blast it with chain oil, try and get it to seep into the threads.

Also if it was yourself who put it on, next time make sure you put some grease or something on the crank arm and the pedal threads before you put the pedals on!

Unfortunately it was me who put them on!

I'm following the directions on the pedal ie going the opposite direction to what it's says to tighten. If I don't get them off is it a case of getting a new cranks?

At worst case the easiest option is remove the chainset and clamp in a vice while protecting the chainset arms, this will make it much easier then removing them when fitted to the bike.

No! Don't give up! Or get your biggest, burliest friend to help.

Do you remember if they went on easy? Any chance they cross-threaded?

If not, then just keep trying and work on your technique. Keep your whole body straight, no leaning sideways to get at the pedal.

I'm the biggest burliest lad I know so I'll just keep going.

Not sure if its cross threaded. Went on easy enough I think. It was a year ago

Penetrating oil. Give it time.
Get in vise and use law of lever.
Drive side/right pedal is normal thread.
Non drive is left hand.
Use copper grease next time.

If all else fails, use a hammer.

I use an old toe clip strap to fasten the crank to the chain stay when I'm swapping over pedals - it's an extra bit of messing around but it makes the job of applying torque to the pedals easier. I would try that before the vice option.

Law of the lever for the win, big lever, small problem:

Point the pedal you are removing to the front of the bike. Some where are around the horizontal. Or as close to horizontal as allows you to put the spanner on slightly above the horizontal. Like in this picture.



Apply your body weight through your heel to the spanner, carefully. You may need someone to hold the brakes, but it can be done by one person.

Make sure the spanner is on securely and is a good fit and then hit it a few hard whacks with a 4lb hammer.

The shock will help loosen it.
