So the new transmission cover will not accept old or new starter mounting screws but the screws will fit in the old cover. What am i doing wrong?
Perhaps someone in the past re-drilled/re-tapped the new (to you) hogshead. Careful you don't force the issue and ruin the threads in the new one; might be that you just have to find the right screw to fit. Or, maybe just one of the three mounting screws is a different thread, and you have them out of order? Just some thoughts off of the toppa' my head,.....harold
Original Model T starter mounting bracket screws onto the hogshead are 5/16-18 thread.

I just wondered if you might be talking about the bendix cover rather than the starter mounting since the bendix cover screws are a known "odd" thread that is often retapped.
Check to see if someone re-tapped the holes to 1/4-20 or 1/4-28.
How would they retap screws to a size smaller?
Sorry. I followed John's query on whether the subject matter was about the Bendix cover. It happens a lot with those. You stated "cover" and "starter screws". It was an easy assumption to make. If it's wrong, please clarify WHAT screws you are referring to--The starter mounting bolts or the Bendix cover screws.
The Bendix cover screws are a number size. It's either #12 or #14, I forget which. Both are smaller than 1/4".
Starter mounting screws. The holes are too small even when i cleaned them with a frayed cable in a drill. Seems weird.
Kep, I'm guessing that you need to chase the holes with the proper size bottom tap. If they are rusty, a frayed cable isn't going to be up to the task. If they aren't the correct size, see suggestion number one. JMHO. Dave
4 brand new correct screws. Seems weird.

They are #14-24.
Kep, try 8mm to see if they fit.
Or maybe you were sent 8mm by mistake?
Somewhere in a galaxy, far, far away, youll lose one and have a substantial oil letter outer. Sure, go metric, maybe a whitworth #7 or some bassturd Russian size. That's great until you lose one, or it gets lost in some leaves on the gravel driveway with your hands full of grease etc etc.
Man up and drill and tap (actually a 1/4-20 tap will go right in)and replace them with a screw that you can replace in the parking lot at the homo depot. Still just sayin' ws
Almost forgot to ad; don't forget to use socket head cap screws on the 12 volt start motor so that they stay tight and don't leak... Gee, this is fun! ws
Socket head screws would work nicely. i can see your thinking but there is no such thing as imperial taps here trouper... i live in a dictatorship where metric is the standard we are only allowed to buy taps with a different pitch than the bolts/screws they sell at chairmanMeow10mega or whatever they call themselves now.
When i bought dozens of snyders brand starter mounting screws (Thought i was buying 4) i need to use them up. Ok maybe i will find a tap for them somehow but still seems strange that every other starter car had the normal size screws.
It's often beneficial to read the posts ahead of yours. It saves a lot of unnecessary thread additions as well as embarrassment.
Im just wondering if the trans cover (hogs head) wasn't an aftermarket job with the starter BORE already cut, but the mounting holes NOT drilled or tapped and some one needed that cover for use without a starter, then drilled and tapped whatever size they are for a block off plate.
Id drill and tap them for the 5/16 screws but don't drill into the MAG coil ring. If the hogs head is off the car even better yet... speaking of being embarrassed, I was wearing some chinaman jeans today ($14 at fleet farm) and wouldnt ya know it, but the zipper locks OPEN... its installed upside down. I was at walmart tho, so the red face moment only lasted a moment. The walmartians never noticed.
Oh and BTW KEP... PM me and Ill send you some 1/4 5/16 3/8 AND 7/16 taps for T work... none of that fine thred or metric business... ws
I just checked the starter mounting screws on my july 27 1925, '26 style engine. They're 5/16"-18, 13/16" long thread. I also have a package of new starter screws - likely from Snyder's - they're the same thread but a little longer, almost 1" of thread.
Old one has ford stamped on it. One that does not fit does not. Looks the same in every other way.
Another note on starter screws: since they are the same screw as was used on the sloping transmission cover door, only longer, they work very well for this use on aluminum covers. Since the doors had to come off for every brake and reverse band adjustment, after almost 100 years the first few threads in the holes in the aluminum cover are usually pretty well gone. If you use a screen, the extra thickness of screen and gaskets combined with the worn first threads often means that the standard 1/2" long door screws are too short to really hold the door. The longer starter screws do the job and look 100% correct. At any rate, it's a lot easier than repairing worn threads.
