Starter Noise

[A Whiteman]

I recently reconditioned my starter.
It runs smooth and the shaft is straight and runs true (no bends or wobbles) on the test bench.

It installed nicely and when the starter button was pushed it engaged and cranked the engine well,

..... however ......

When the starter button is released (without the engine starting) it makes a bad 'graunch' as the bendix disengages. Now It should not do that at all!
No 'bad noise' on engagement and crank, only on release.

I have replaced the Bendix with a new one, same issue.

Next steps: 1) I will swap out with another starter (why not), and 2) examine the ring gear.

Any ideas what causes a graunch on disengagement??

Thanks for your suggestions.

It all hinges on just what a "graunch" is.

Is the bendix cover an original? Repop covers are smaller ID & if not centered can be hit by the head of the drive head bolt.
Try a brief crank with the cover removed to exclude the cover.
Briefly is key in that you will dump a lot of oil thru the missing cover opening.

Are the four starter mounting screws tight ?

Do you use a six volt battery or something else?

[A Whiteman]

Hmm, could be a 'graunch grounch or maybe a bit more of a grruumm graunch

Yes, all original parts and cover
Yes all tight
It is a 12v converted starter, not 6v with 12v in it.
No, I have not had this problem before the refurbishment

If your 12 volt converted starter is a new acquisition, maybe it's going to be on its return trip for fixing ?

Adrian the T starter has to have a different wiring & bus cut to convert it to a12 volt starter that you can safely use on a T. You might consider Jeff as a source. He restores them and may be able to help you check to see if it was done correctly. If you have another 6 volt starter you could challenge the issue with the 6volt starter to see if the problem goes away. I’m not saying stick with 6 volt but rather get advice from Jeff on what you actually have concerning the 12 v starter.

Thanks John, yes the starter is rewired and modified bus, we have been using this solution here for many years and across a lot of cars with no problems ... until this time ... :-0
