I recently got a 1980 Grande and am starting to do some repairs. Right now I'm having a problem with what may be a pretty basic thing.... the pedal mechanism. Something seems to be broken or loose inside the case where the pedals fit into, because the bar holding the two cranks for the pedals is very wobbly, making it difficult to keep the chain on. My problem is that the pedal cranks seem to have rusted over too much to get them off... I work on my mountain bike alot, but there's no easy way (like just using a hex-wrench) to get these things off and get inside. Any suggestions for my dilema? Thanks.
Also, is there anything posted about the best way to get the engine off of the Grande frame to work on it?
