I need to get the belt pulley off my crankshaft without damaging the crank. I used a punch and tried to drive it out with no luck. I'm afraid to use a torch on or around the crank any suggestions?
Are you driving it in the right direction? One side of the pulley has too small a hole for the pin to come out.
If it isn't moving at all, maybe you can oil it, get it started in the other direction, oil that side, then turn the crank over and drive it out.
Did you remove the cotter pin? The large side of the pulley has a cotter pin on the inside of the pulley through the pin. Remove that cotter pin and take a punch small enough to go through the smaller hole and drive the pin out. It should be a snug fit, but not tight.
yes cotter pin is out ,and driving it from the small end. I'll try again and get back.
I went back and tried again 4lb hammer and punch. nothing but swelling the small end.
I would recommend that you do not hammer it anymore. If you really need it out, cut off the ends and drill it out with a drill smaller than the pin, then try pressing it out. Why are you trying to remove it? If you need to replace the pulley, or the timing gear I can understand why, otherwise, just leave it in place.
Thanks I got it out!
the pulley needs to be off to have the crank ground
