Hello, i am working on dissmantling my 96 blaster and have the top end off. I have the screw removed from the rotor assembly, but cant get the rotor asssembly itself off. I wanna remove the connecting rod, as it looks as if it has damage around the rod. I could move the connecting rod all around with the gears moving and what not, but once i got the nut off, it is making crunching sounds from the rotor assembly. its now seized up and i can't get the assembly off. whats going on???thanks for your help
