OK, here is where I usually break something so I did a search and came up short. I have what I believe to be a late '42-'48 ford flathead generator. No probelms with dis***embley except the pulley. I removed a C-clip off of the snout and the pulley appears to be threaded on. I tapped it a bit and tried to unscrew but could not. So my question is.......Does anyone know of a way to remove this pulley without breaking anything? Any information would be greatly appreciated!!
Use a strap wrench to hold the armature still. Some of the modern ones have a strap that is soft and rubber covered, just about perfect for the job. In the future...before you remove the generator from car, overtighten its belt...don't try to run it that way, though. Put a ratchet on the nut and smack the handle of the ratchet sharply with a hammer...the shock oft allows you to pop it loose right there. A steady pull on the ratchet will spin over the generator and likely the engine too without loosening the nut, suddenness does the trick, just like removing the bolt at front of crank.
Bruce, Thanks for the hasty reply. This particular pulley did not have a nut holding it on rather a cir-clip and that is all. I removed the clip and it appears the end of the armature is threaded as is the pulley. Are you saying I can put a strap wrench on the armature as well as the pulley and un-loosen?? The pulley # is 01A-10130
My answer was seriously muddled...someone must have watered my coffee! Anyway, strap wrench is good safe way to grip armature. On the pulley, it can be gripped at sheave by the big size channellocks or gripped with its own belt, put into sheave and pinched up tight with vise grips. You have the cast version of pulley, so if grips or a vise are used be cautious. Those are a bit brittle.
I've always managed to get them off without much gear...I just remember a lot of screaming and cursing, once you've scared the damn thing it'll come right apart.
I just went through this on a '41 rustbucket gen with an 01A pulley, I just took a flat ended punch and hammer and gave it a few raps (counterclockwise) and it spun right off.
Any kind of sudden shock is good when you are unscrewing something on a hard-to-hold rotating part. But remember that broken cast iron pulleys are common...thin, brittle... Best to SCARE them off...once you are speaking in tongues and learning new curse words from yourself, off they come!
