Take the non drive pedal off (thread turns clockwise that side). Remove lock nut and cone nut at the bottom bracket, again, I think they turn clockwise. Pull the arm through the bottom bracket. You may find it best to pull the non drive side bearing out to give you more clearance. If you need to remove the bearing cups, just bash them out with a hammer and drift.

from memory

1, remove pedal on non chainring side

2, remove lockring and washer, they undo clockwise (i hope)

3 remove bearing race (same way as in 2)

4 gently remove bearings

5 pull crank out and bearings on chain ring side

6 gently but firmly tap out the bearing cups in the frame, use a drift and hammer

if you need any more help, let me know
