cheers for the responses boys,
i thought the ol' give it a good twatting might be the best idea, but wasnt sure if i should maybe heat the crank arm up before i do this? i was planning on getting it helicoiled if it is sort-able, will have to try and get the pedal out first obviously.
i dont think the crank arm is cracked...i cannot see anything thats fo' sho'.
kenster...i tried that using a wee alan key as they are V8's with a 6mm allen key in the rear of the axle, but to no avail. it seems to catch a thread and then loses it again. also keeps going squint, which i dont really want to do as i will hopefully get it helicoiled.
ill have a shot this weekend gents and if i need anymore help will shout here
