Greetings:

Been putting a car (74-360 charger) back together and to start off I have some electrical issue which isn't really my concern right now.

(jumping the starter relay i have what I want for now.)

Unfortunately the starter only spins and the first google search I seen was a flywheel mounted backwards.

This mini starter I had bought years ago (~6) for my other charger but the headers would not allow it to mount. So it's my assumption there isn't a problem with the starter.

Wondering, can a starter spin without extending?
Would removing the dust shield and taking a photo be helpful to know if the flywheel is indeed on backwards?
Or... is it only the worst case that I will be removing this transmission?

Thanks,
John
 
Well.. with the *current 2 agree's you have i'll pull the starter and test it I guess. Easier than the thought of dropping the trans

Thanks.
 
Flywheel , so therefore a stick shift. 10 1/2" or 11" flywheel? A starter for a 11" won't spin a 10 1/2 flywheel.

Starter is the same, it is the position on the bell housing that is different between the 10.5" and 11" bell housings. Mini starter should do both types as long as the bell housing is correct for the flywheel and clutch size you are using.

You're right, I just explained it badly! Thanks for the correction!

Wait... I think I've seriously lost my mind. This is a torque converter I'm talking about so there is no way there is an issue other than the starter.

I think i read the first post from google that referenced a flywheel and ran with it.
Sorry for my confusion.
 
Hopefully you have no broken teeth on the torque converter.
Otherwise, yes you will be removing the transmission.
 
The starter solenoid does two things. 1) it kicks out the gear to engage the flywheel and 2) it engages the contacts to send the high current to turn the starter.

That said, if the starter is turning then the solenoid is working and if the solenoid is working the gear should be kicking out since its a mechanical connection that's unlikely to break.

My guess is wrong flywheel.

It may be a torque converter but that attaches to a flywheel via a flexplate. I know little of automatics - are there different size flywheels for those also ???

Well, there is one other way....the flexplate 'forgot' to get bolted to the converter:D
(Don't laugh, it's happened!)
And to adresss your title question, you can't put a flexplate on backwards; the holes in the crankshaft flange are offset and they wouldn't line up. The flexplate-to-converter holes wouldn't line up either.

This is the torque converter i bought back in 2016.

No.. that definitely isn't the case. they were a PITA to get back on .. one at a time laying on the driveway

As i mentioned.. it was a quick google search and the first thing I seen... who knows.. maybe it wasn't even mopar related.
 
Oh. I just thought of something that might be my problem?

when I bought that mini starter I bought it for my other charger which is a manual.
 
Starter Bendix or not kicking in properly. Take it off and hook it up with jumper cables to see if it kicks out and spins.
 
Agree with Ceedawg. A bench test is a great idea. That way you can see if the starter is the problem, or something else.
 
Or if you don't wanna take it off, get the car off the ground and then have someone you trust hit the key while you are under the car and watch the starter......you should be able to see it either not engage or engage on the teeth on the torque converter. I am a 4 speed guy, but I believe all these older rides had the teeth on the torque converter and then just a small little flex plate between them to connect the two, so the teeth should be lined up no mater what as long as the torque converter is seated correctly and the trans is tight to the engine.

well.. the key isn't an option due to the electrical issue I still have to chase down.
but.. i can either set up the jumpers down there or have my son jump the relay.

I guess i've never watched a starter engage while mounted but I'd assume the dust shield would have to be removed for that to exposed.
 
You can jump the starter posts right down below. Touch the smaller one first then the big one.
Use a heavy gauge wire with a lug on the end if you can.
Yes you will need to remove the dust shield, which means pulling the starter.
If you try to bench test it under the car or on a bench, just be careful to hang tight on it they really try to jump when actuated.
 
Ah ok, yea I am not familiar with the autos. I can watch mine on the 4 speed no problem without the bottom shield on.
