new thread?pully size

[panamaguy]

Hey Lou,and anyone else,my new s/g has a smaller diameter pully than the old s/g.The belt groove is the same but if I put on the old pully I can only get a couple of turns on the nut and no lock washer.Any ideas? Thanks

If you look at your old s/g remove the woodruff key then you'll find a spacer. Do the same to the new one and see if they are the same size (length) you may have to use the old spacer on the new s/g to get the spacing correct. Report back

OK,so the old s/g has 3 screws that hold the cover to get to the spacer,the new s/g doesn't have those screws,it looks like the rear cover is held on by a snap ring.I've tried using a small piece of wire to get to the ear on the snap ring but there isn't enough room between the armature and the rear cover to get it off,so I'm thinking that that ring doesn't hold the rear cover on.I tried tapping the cover with a hammer but don't want to go to hard on that cast aluminum plate.Whats my next step?Thanks!!!

Look close on the pulley end of the armature you don't have to do anything but remove the pulley and woodruff key the spacer just slides over the armature shaft. Post a pic if you can't figure it out OK???

OK gotcha,the hew s/g doesn't have a spacer.My old pulley won't slide in far enough to put on the lock washer and nut,I can only get 2 turns on the nut and that's without the washer.Any problem using the new pulley witch is a 1/2" smaller diameter? The grove for the belt is the same size and the overall length with new pulley on is the same as the old set-up.Thanks
