1953 Dynaflow/Hydromatic starters...

[Charles]

Was there any differences in the 1953 Hydromatic and Dynaflow starters? My starter has been rebuilt, but still acts up. My car was originally a 1953 Dynaflow car, but the previous owner swapped in the hydramatic. Wonder if he kept the old starter...

Any info is greatly appreciated

Charles,

Nope. All the same. The only exception in the Parts Book is that ther were two different part #'s. The first, # 110 7602 and it says when exhausted, use # 110 7619. By the way, how did you make out with the valve lifter situation?

Just replied on that issue.

Damn...why is my starter grinding??

Me thinks it is time you pulled it out, and to pieces to see if the bearings are gone.

There shouldn't be any grinding, but if there is, I would be looking very carefully at all the parts, including the condition of the ring gear.

Ring gear was checked when I was rebuilding the engine. The teeth showed slight wear, but nothing that was deemed to be too serious.
The starter had the gear replaced, and the solenoid replaced by a starter rebuild shop. The probelm was there before I did all this, and it still does it. I'm lost. Maybe there is an electrical issue (wiring is pretty old and stiff) that is keeping the starter from functioning correctly?

The best way to do it is get it out and do a bench test to see if it spins okay.

Now, there is "Grinding" and "Grinding"   One is the "Destruction" variety, and the other is the "geez i'm tight" variety.

Have you had a chance to put a Volt Meter across the Battery Terminals to see what the voltage is like, between just sitting, and cranking?   That is a good indication of just how the system is working.

With 12 Volt, a Starter Motor will usually only drop the charge a couple of Volts whilst cranking.

I would be most interested in hearing the outcome of, and solution to, this problem.  I have a friend with a '64 Cadillac that does the same thing.  Starter would grind on the ring gear teeth rather than engage when he bought it a few months ago.  Ring gear replaced with new, starter replaced and it still does it on occasion.

Charles,

Here's something to consider, seeing that the starter was giving you trouble before the rebuild. You have sort of a unique car. One that was originally a Dynaflow car that was refitted with the Hydramatic. In past discussions, your engine and frame #'s match. This means you have the original engine in the car. The 331 Engines that were fitted with the Dynaflows, had a DIFFERENT crankshaft, flywheel and bellhousing than the ones fitted with the Hydramatic. I'm wondering if ALL these were changed when the Hydramatic went in? I especially wonder if the crankshaft was changed. I'm just thinking, that if they wern't, you may have some sort alignment problem between the starter and the ring gear that's causing the grinding.
