Broken Starter Housing

As you can see by the pictures, I have a significant starter issue.

Parts house guy says motor locked up, mechanic next door agrees.

I'd never experienced this problem, got my pull handle & 3/4 deep well socket & turned the front crank (clockwise) a turn or two.

If crank turns, the motor isn't locked up...so...what caused this?

I'd rather not replace more than 1 starter.

Your ideas/suggestions are appreciated.

It's possible the starter wasn't shimmed properly during installation.

Did the engine backfire while trying to start it?

I would agree with the backfire question.

Also wonder about a low battery voltage during crank (slower then normal crank speed) and when the engine started the bendix gear hung in the flywheel.


Regards,


JD

No backfires, newly installed rebuilt Quadrajet. Had moved it to an exit from the storage lot, shut it off & went home for dinner. Came back to move it, cranked it, stopped (still getting used to pump the accelerator to set the choke) & resumed cranking after 20-30 second delay, the starter was broken then or just before as all I heard was the gear spinning without contact.

How would you determine the difference between slow & normal cranking speed?

Did it sound like starter was cranking hard and normal, or like the batteries were low and about to die?

Several things going on here:

Had engine run with new carb?

Did the engine cough or try to fire during initial crank?



What normally breaks the end of the starter is either misalignment of the starter on the bell housing, kick back from the engine during cranking, or bendix hung after engine starts.

Regards,

JD

Go to AutoZone and get a lifetime rebuilt starter and see if that fixes it. Is the shaft on the starter also bent? A backfire could have caused this but I would think you would see other stuff bent as well. Could it have hydrolocked from fuel or water in the cylinders? I assume you drive this often and it is not something you found in a field?

I would second the Auto Zone starter and make sure you have the right bolts that are knurled for good alignment. Also GM put that brace that goes from the rear end of the starter to the block for a reason. If it's missing (and it usually is) get a new one soon. Were the bolts tight when you took the starter off?

Had cranked right up 3 times after installing the rebuilt carb.

Several things going on here:

Had engine run with new carb? 4-5 minutes each time above.

Did the engine cough (NO) or try to fire during initial crank (no issues).
What normally breaks the end of the starter is either misalignment of the starter on the bell housing, kick back from the engine during cranking, or bendix hung after engine starts.
Bought & installed a reman Carquest Limited Lifetime warranty. Cranked, fired & started after 10 seconds.

We're running again...

R terminal wire

Looked up Youtube GM starter wiring. Shows a wire to the "R" terminal, my starter had the battery wire, a 12G wire to the "S" terminal and a 6G ground wire to a starter mounting bolt. Is there a need for the R terminal wire?

No, it's not used.

Didn't have the brace, did have the knurled bolts & yes, the bolts were tight (probably 50-60 ft-lbs).

Where can I get the brace?

I have never seen a rear brace on any of my 454 Motorhomes.
Never had a starter housing crack either

6.2 and 6.5 diesels used a starter brace. Might can adapt one. Being your starter has staggered mounting bolts I wouldn't worry about a brace. Only time I've ever broke the nose was the engine kicking back.
