Starter issues ..... I think

[Maxximus66]

So a couple days ago the starter on my ‘66 (170ci straight six)just started sounding like it was spinning and not engaging the flywheel... it was old so I just went ahead and replaced it . However , the new starter is not cranking the motor either .... it is somewhat engaging the flywheel as the fan is spinning , but , it doesn’t sound quite right and the fan seems to not be turning as hard as normal . I’ve got good charge and plenty of volts coming off a newly installed Optima red top . I’m banging my head here guys ..... could this be a shim issue ? A wrong tooth count issue for the starter ? Or just a bad reman starter ? HELP ! Thanks y’all !

Could be any of those, or a flex plate with some bad teeth maybe.

I'd pull starter out and look at flexplate with flashlight.

Then (if it looks ok) I'd take my new starter down to parts store and compare to old one. Depth, tooth count, etc.

Good luck!

if the fan is spinning, how is it not cranking the motor over?

Pull apart and clean all of your wires - battery posts, connections at the solenoid and starter and Your ground cables from motor to frame/battery, body to frame, etc. also, see if there is corrosion in the cables. Might need new ones.

Regardless, I would look into a mini starter from wild horses or other vendor. They make a night and day difference and are easy to wire up.


I had an issue when I put in a used auto tranny and starter. It did not sound good when it was trying to start and only managed to start it once before just being too weak. Tried new battery but no luck.
wiring and grounds were all good.
Figured it Must be the starter and a new mini starter now cranks it fantastic.
