Also most of the delco alternators only have a small front bearing (smaller than the ford generator) which was never designed to carry the weight and load of a heavy metal fan on the pulley. Try harder and fix your original generator. Regards, Kevin.

No voltage at all coming out of the generator.
I took the generator apart and the commutator (sp) has closed Circut to the shaft. Brushes look new and couldn't find anything wrong with the field coils.
I put the generator back together and tried to motor the generator with the belt unhooked and voltage regulator disconnected. The armiture post was going completely to ground.
The inside was very clean, no signs that anything burnt up.
I have not taken it to a shop as non are close to where I am.
I may rebuild the generator but at isn't going to happen overnight and I would like to get the car going sooner than later as we have a pretty short summer.
Will the smaller bearing wear out faster? Probably but if it last 20000 miles instead of 200000 miles I'm probably okay with that.
The loads may be greater but the speed will be half with the larger pulley especially when you consider a a Sbc will rev a lot higher that a flathead.
G.M. has the slow speed charging problem solved.
Fitting isn't really an issue from what I've read.
I may go back to a generator once I get it straighten out but I probably have a spare gen and reg in the trunk on long hauls.
I switched to an alternator on my 58 gmc after a regulator failed 3 hours from home.
On my 46 chief 1600 kms from home I ditched my original generator after it failed and went to brand new generator with built in voltage regulator and had no more problems.
Thanks
