The parts book calls out square head bolt, square nut, cotterpin.

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.

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
20553 1/4 x 28 sae x 9/16 Sq head bolt
A 21666 1/4 x 20 sae (3/16 x 1/2) Sq nut
Actually hex head bolt and 1/4 x 20 sae that's why my search.Comment

Here is one way:
Before removing distributor be sure to COMPLETELY remove the bolt that holds distributor to the head.
JUST loosening the bolt in most cases is not good enough.
It depends upon what type of bolt was used last time.
If the correct original type bolt was used then you will have a problem IF bolt is only loosened.

I've been looking to buy some thick headed hex bolts 1/4 - 20 and have not found a source. Scrounged through all my old jars of bolts, lots of different sizes but no 1/4 - 20's.04-18-2021, 09:18 AM -
Can someone help me find where the head lamp bar mounting hardware is discussed in the RG&JS? This would be the carriage bolts, nuts, etc. that mount the bar to the fender brackets. I've looked in Sheetmetal (fenders), Lamps (mounting bar), Undercarriage (fender brackets) sections and I must be missing something. I'd like to confirm the mounting hardware sizes and finishes.gif "confused")

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 -
This picture is from Brattons website. It looks to be a drawing from Will Cronkite labeling the proper bolt placement. Very good drawing, just a little hard to read after printing. I was curious if this is from a book. I have the judging standards book that I will check out tonight when I get home. I am just surfing the internet at work wishing I was in the shop!

I got the bolt out with his snake magnet suggestion. Took another hour fishing blind. This time I will send a line up through the bolt hole and tie it to the bottom of the bolt so I wont loose it. Now, does anyone remember if these bolts are a snug fit or real loose in the bell housing when installed? I will do a search for a borescope when I get time. Thanks everybody.png "smile")

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
