I recently found what I believe to be a 1976 Raleigh Sprite at my town dump. I'm beginning to strip it down and prepare to restore it but I'm having some issues removing the cranks. I'm not that familiar with Raleigh's in general. They look like 3-piece and each arm has a pinch bolt, I loosened/removed the nut from each pinch bolt but everything still seems pretty locked tight. There is some rust build up and I'm worried things might be fused up.
I've tried some brute force to no avail and I figured I would see if anyone has any tricks to getting these types of cranks off before I really go to town with a mallet. Am I missing something? or do I just need to look into solvents and more force?
I can post pictures later if needed.
Thanks in advance
