I received a PM asking about cotter pins. As I was looking up the information it occurred to me that some folks might find it useful to have several fastener references together, so here they are. These don't cover every item, but they're a good start. I'll start with the least helpful and end with the best.
This Model T era chart shows where things go, but it gives wrench sizes, not bolt sizes.
Maybe George will have an update on this.
This T era chart is from the Northern Colorado Model T Club's website.
And here's the most extensive list of all. It's also on the NCMTC website. It's missing a few items, but covers most of the chassis fasteners:
Hey Steve, on the first big picture, I see the hex head or square head and the size, but what do the other numbers after that tell you? (I just don't know how to read the chart all the way)
For instance at the top near the middle is the Body Bracket Connecting bolt and nut, the bolt being 9/16 hex head, but then there's the 1903 with the symbol below it, what does that tell you?
Lots more symbols and numbers for the nut.
Those other numbers and little drawings show which wrenches can be used.
Steve. Thank you for posting this. What a great help.
Thanks Steve!! Great reference...
It says, "many a stranded motorist has borrowed a hair pin from his wife and effected an emergency repair". That sounds a lot safer than the advice Shell Oil offered decades ago when they suggested we flag down women motorists and request their pantyhose to repair a broken fan belt.
those numbers correspond to Mossberg tool numbers. I used to think they were Ford numbers, but I collect tools and came to the conclusion pretty quickly of my error.
Cotter pins are available from hardware stores in fairly large boxes with assorted sizes. I find it easy to find the correct size from these boxes. (Keep boxes in my garage)
Some nuts and bolts I also keep as the hardware store is some miles down the road.
