Model T Ford Forum: Forum 2009: Table of bolts, nuts, cotter pins, and other threaded parts

I have added a new page that describes the various threaded items of a Model T on the Northern Colorado Model T Club web site.

http://clubs.hemmings.com/frameset.cfm?club=ncmtc

From the main page, select the TECHNICAL link on the left. From that page, select the “BOLTS – NUTS” link on the left. This will bring up a PDF file containing all information about all the bolts, nuts, cotter pins, and threaded items contained on a Model T. This document is a work in progress. There are various colored sections: yellow – information about these items is under investigation or cannot be located in parts books, blue – layout or analysis is not yet complete. The blue is mostly in carburetor and electrical. I also need to address body bolts.

This document is based on the orginal document created by Joe Boyers.

If you have any information about any of the items or see any information that is incorrect, please send me email so I may correct the file. If you have any recommendations about a better organization, I would also be happy to think about them.

One of the possible restructures I am considering is to separate the bolts/nuts from the cotter pins from the “other” threaded items (e.g., exhaust manifold). I also need to add headings to each page.

Enjoy

I think it would be neat if one of the parts suppliers would get a major cotter pin manufacturer to make the common cotters for the 3/8-24 bolts that are used everywhere on a T, so we don't have to cut them off. I think Ford specified either 9/16 or 5/8 on these. I would buy a box of them.

Sorry for the large size.

That little brass cotter pin that holds the shutoff valve in a brass fuel filter sediment bowl appears impossible to find and is evidently an odd-ball size.

Thomas, that is a very nice diagram. It is very easy to do a Right Click with the mouse pointer on the picture and then Click Save picture as to put the picture on the computer's Desktop. Then the picture can easily be made smaller or larger, but if you made it smaller and put it on this website, it would be difficult to read when yo did the Save to desktop routine.

Larry,
I have a source for those odd ball size cotter pins, but the minimum quantity is 1000.

Does anyone know if the original cotter pins had a long and short half like modern cotter pins or were both halves the same length? A can get either in 3/32x5/8.

Once the cotter pin ends are bent, no one is going to bend them back and measure them.

Bending the cotter pins with one leg longer is a much easier task.

The cotter pins with one leg longer seemed to have been more common. One engine that appeared original had the short leg down and not bent at all and the long leg bent back over the top.
