removing drive gear roller pin

rusa7January 27, 2007

Hello experts,

I followed the procedures on this forum to expose my drive gear. The drive gear was all chewed up. But I cant seem to get the roller pin off. It seems to be very tight. Is there any trick/tool to remove it. Am I doing something wrong. Should I just insert a screwdriver and hammer the roller pin out.

Help please !!

I tried with a 5/32" punch but it still doesnt want to seem to come out. I am afraid if I hammer too hard it might bend the shaft. I have tried lubing the roll pin with WD-40 but it hasnt helped. Any other ideas much appreciated.

Make sure the motor housing is still attached. I.E. still slid over the shaft. You may want to put the punch in a set of vice grips, otherwise make sure it is positioned perfectly centered on the roll pin and smack the crap out of it with a hammer. As long as the motor housing is still attached you won't do any damage to the shaft.

Thanks very much. I had trouble posting back yesterday. I took the gear/sprocket assembly off. Then I had to cut part of the plastic off with a dremel tool to have better access to the roll pin. Then I could hammer it out by holding it in a vice. The roll pin was really tight. Put the new gear in, lubed it well. The garage door is working fine now

Thank you,
