I have had a starter issue since getting my Ford Super Deluxe Convertable. It constantly jams and has a very slow turn. I have done all the usual diagnosis. Teeth look fine on both the starter and the flywheel, hits in the center of the teeth on the starter. I added a hanging strap and replaced the battery cables, cleaned the metal to the body the ground attaches. I should also say they had installed a 8V battery to compensate, I have replaced that with a 6v Optima. I bought a new 6v starter with modern bendix from Dennis Carpenter and as you can see their instructions state to remove the starter plate and grind to create clearance for the larger bendix. I don't have a starter plate. Any thoughts? I can grind my opening to create clearance, doesn't look like much is needed. I'm at my wits end on this. Also any Flathead mechanics in the Chicago area (I'm in Naperville) that can be recommended? It never hit the road last year and I am running out of thoughts on what to try! I have it on a lift so easy to access.

when I bought a new starter for the 8ba in my '39 I had Joe's Antique Auto substitute an original style Bendix in place of the modern style to eliminate the clearance issue. IIRC Van Pelt's sells the original style as well. Just a thought. ______________ No signature

Makes me wonder if you have the correct flywheel / ring gear assembly. Mike "Kube" Kubarth

I think the original Bendix was probably weak/worn and thus the primary problem. I suspect its unlikely someone replaced the flywheel which would have required considerable work - however, do a tooth count to see . I also believe its unlikely the 8 volt battery damaged the starter motor. Some who have converted to 12 volt electrical systems still use their 6 volt starters without effect, except long term its best to up grade the starter motor to such voltage. The original starter motor may have been or is functionally okay - an electrical shop can test it to determine that. Before you do any grinding for the replacement, there's no turning back from that, I think you should test the original motor and try using an original style Bendix.

You said you replaced the battery cables. Did you get the correct 6 volt cables or were you given the smaller diameter 12 volt cables? There is a big difference between the two and can affect starting.

as for the cables, yes they are the correct 6V cables.

as for the starter, First I replaced the bendix with another traditional bendix, then replaced the starter as well. I am wondering if it is a clearance issue.

In regards the the Flywheel/ring gear- Well that certainly has crossed my mind as I have done the other things with no luck. since I have a lift, I have (as well as can be done w/o removal) inspected and counted the teeth. Has the right number for a 48 and doesn't show any wear. I would hate to pull the engine, hence my desire to try this and also find a knowledgeable flathead guy to look at it before I pull the engine
