Are those 1/4"? Engine pan bolts? -
Yup. spent years looking for square head bolts before I found out its wrong in the parts bookComment

Yeah, there was one original bolt in my Tudor when I got it. And I thought to myself, bet that's the original bolt and all the others got dropped or shined off because they didn't want to have to deal with those fine threaded square nuts. Plus the tiny cotter pins. What about the hardware book? I'll have to look that up later tonight to see what it says about them and the finish. I copied pages from it when it was loaned to me but I never printed them out. I'll probably just pony up and order one someday beings I drool over things like that. I knew a contractor years ago that ran all Cat equipment and if any of his mechanics put anything but a Cat bolt on something he fired them.Last edited by Dennis; 09-21-2017, 09:36 PM.Comment

Is that the only cotter pin nut on the car that is not a castle nut?Comment

I think so. It's the only one I've ever come across.Originally posted by Ed Saniewski View Post

I found one at a swap meet recently. The guy gave it to me. So I'm up to 2 out of 6. Need 4 more. Anybody ever notice how hard it is to find 27-early 29 parts? I haven't seen one single drum light in 4 swap meets I've been to.Comment

Dennis, there were atleast 3 drum tail lights at the Lincoln swap meet last March. Prices were OK, but none of them script so I passed on them. RodMuch of the social history of the Western world, over the past three decades, has been a history of replacing what worked with what sounded good.Comment

It's been 37 years since I've been to Lincoln, and unfortunately it wasn't a Model A swap meet. Just another grain elevator.Comment

Jim, I picked up 5 of these this week from a friend that builds ratrods. Also 7 more shocks. Took him over 3 sides out of gas tanks to use to replace where the tanks he had were rusted out and 4 messed up shift levers. RodYou do not have permission to view this gallery.

Rod,
Those nuts "look" too thick,..I thought they were about .125" (1/8"),...also, I don't remember the lock washers for the cotter pin bolts. The pans that I repaired,..you could see the square
head left a "witness" mark in the pan...no lock washer mark! I did find one bolt and nut on a spare frame that I used as a pattern to make 4 1/2 sets for my Roadster, plus another car.Comment
-
This is the way they were when I took them off of the frame along with what was left of the ears of the pans. Lock nuts were under the bolt heads and not the nuts. I was going to ask which other place on the A uses these lock nuts as I am missing one. But since they might not have been used on this application, guesse I will skip this question. Rod

Hows about that "HIDDEN" BOLT in the timing cover???---Minerva didn't have one & the hole PUKED oil, like a DRUNK!Comment

A Parts Price List book from 1928 should give the dimensions for the engine pan bolts and nuts. I don't have mine handy, or I'd look it up.Comment

January 28 parts book

I made this illustration based on Murray Fahnestocks recommended pattern in the Model T Ford Owner. The original in the book is small an not very useful while actually doing the job.
This can be printed out on an 8 1/2" x 11" sheet and used while torquing down the head bolts. Recommended max torque is 55 ft. lbs.

First, this is a fine point question, so if you have no interest in fine point questions, just ignore this post. I have a question about engine pan fasteners. I might be posting this in the wrong place. The question involves the 1/4-28 bolts and nuts that attach the panels to the frame. According to the Standard Hardware booklet by Mick Isbell, page 11, the bolts are 9/16" long with square heads...02-06-2020, 12:57 PM -
OK...I have two assembled carburators and have a problem.
I can not seperate the two halves and believe me...I have tried.
I have tried soaking them in evaporust, Heating the only threaded area on the upper half...nothing.
Any other suggestions...I sure do not wan to ruin these.
Thanks.

There are a few spots on the Model A/AA Ford where one can insert a bolt in either direction to attach a fixture.
Is there mention of specific "Correct Bolt Orientation" for any of the assemblies in the Standards OR can we put them in the way we think and be done with it?
For instance...which way does the bolt attachment go when assembling the generator to the engine?...03-28-2019, 12:16 AM -
I’m rebuilding the rear axle on my 1930 roadster. On dissembling the axle, I’ve discovered that the driver side housing is 1928 and the passenger side housing is 1929, based on location of seams. I also found that all 20 differential bolts are not original, as they have no shoulder above the threads, and all had lockwashers. So, at some point before I owned the car, the axle was replaced....07-26-2020, 09:43 AM -
I found a 3/8" course threaded domed 3/4" bolt with some parts I got with some other model A parts. Maybe it isn't used on model A's, but I thought I would see if anyone knows what is is used for or even if it is used on model A's.
Thanks

Would anyone have a photo of the special 1928 E-Brake attachment bolt, A-20930: 3/8---24 SAE x 1-17/32 special head bolt (with Cotter Hole)?
This is the bolt that attaches the E-Brake to the A-2797 Emergency Handbrake Lever Arm
What does that "special head" look like?
Thank you.

I have a Standard Hardware Guide that has no date when it was published. I contacted Jim Canon months ago who is the technical director of MAFCA who forwarded my email to the JSC director at the time. I don't remember the director's name without looking for that email. Back to the guide I have found several mistakes and have forgotten a lot of them. I remember the chairman mentioned the difficulty...06-10-2018, 02:35 PM -
