Re: 1/2” Bendix
Distributor bushings re .5" ID. Don't know if that would work for you. Or have a custom bushing/sleeve made. Use a later starter with the 5/8" shaft? Different switch, however.

Re: 1/2” Bendix
There is great bendix info on pages 570 to 572 of the Service Bulletins. As far as I know you cannot use a starter with a 5/8 shaft in place of the 1/2 inch shaft type without modifying the flywheel. Perhaps someone has a bendix available for a 1/2 starter. Post of photo or your damaged bendix someone may have a stash of old parts. good luck Supergnat

Re: 1/2” Bendix
The issue is that it is not a Bendix starter drive, the 1/2" shaft used an Able starter drive which are not available. Easier to change to a starter with a 5/8" drive.

Re: 1/2” Bendix
It is my understanding that you cannot change to a starter with a 5/8" drive, as the gear diameter is larger, even though both are 10 teeth.
I would post what you need in the wanted forum. Check with Berts. Look on eBay.
I do not believe parts are available for these from our vendors.

Re: 1/2” Bendix
Really? The service manual suggest that they are a straight swop... or am I misreading it?

Re: 1/2” Bendix
The Page 284 of the service bulletins announces a new 1/2 inch starter assembly A-18475 with the new Special Drive installed. That can be a direct swap. The 1/2 shaft of the starter armature was machined to accommodate the new Special Drive. My October 28 Leatherback has the special drive (1/2 shaft which replaced the Abel drive which was used from Oct 28 until Ford transitioned to the 5/8 shaft starter drive Bendix drive which was then used until the end of production. Special Drive A11350-DR. See pages 303-305 of the Service Bulletins for more information

Be careful, 1/2" is the size for model T, but it spins the other direction

Re: 1/2” Bendix
Found these starter parts on ebay this evening. Someone with an early 28 needs these parts.

Re: 1/2” Bendix
Working on a Model AA truck which the engine number puts to July 1928. The truck has a left hand brake lever and the earlier "no emergency brake shoes" arrangement. I.e an "early" AA truck.
Early with the Multi-disk clutch.
I was surprised to find the starter motor painted "red" (an obvious aftermarket replacement) with the "non-square" starter pedal switch (i.e. Later.) AND - this is the surprise I didn't expect - a 5/8" shaft bendix drive - like all the rest of my starter motors on hand.
I don't believe anything "special" was done to machine the flywheel - and the bendix appears unmodified.
Reading through the discussion above, I checked a multi-disk clutch flywheel/ring gear with a single plate clutch flywheel/ring gear. The two ring gears are IDENTICAL. Which tells me if the starter mount hole/location is identical between the AR housing and the later housing - then the bendix pinions must be the same
As I get further into this I will report more detailed findings.

Re: 1/2” Bendix
Joe, I am not familiar enough with the availability of starters etc over there but IMO, your best solution would be to end up with a 5/8" shaft. Surely they are available at a reasonable price over there.
I have a couple of 1/2" bendixes that I will never use. They are your for the shipping. Otherwise, maybe try Sammy Guthrie at Arizona Model A. He has quite a lot of used parts (and new).

Re: 1/2” Bendix
THAT is the conundrum. This is a multi-disk clutch - but it seems to work fine with the 5/8" shaft "aftermarket" starter.
The only thing I can think is someone "cut the corner off the flywheel" to give room to pass the bolt heads on a 5/8" bendix. Until I get there and see it for sure.
