So ya bunged up your threads pullin' the pulley and end plate off un your generator.
Not to worry, just chase it with a die. Oops.....you say it mics out right around 669"????
Whoa there hoss!!!! that taint no English thread size. So getting the thread gauges out
I come up with a 1.25mm pitch. Ya mean Delco-Remy was using metric threads in the
40's???? Yep. m17x1.25 special fine thread on those 6 volt Delco generators.
So don't screw up your armature by thinkin' it's got some sort of special English thread
it's by gollly, sho nuff metric.
