Hello all,
I had an interesting experience while driving home this evening...it feels like the pin (7221 in the diagram below) that prevents the floor shifter from rotating either broke or somehow worked its way out of the groove in the shifter. The shifter now rotates, which makes finding 2nd from 3rd interesting to say the least.
I removed the shifter when I redid the interior, and recall that the pin that is (was) there looked to be home made, as it didn't resemble one that I bought to replace it, which was similar to that shown in the small picture below. That pin got disfigured when I installed it, so the old home-made pin went back in.
I just found where the Chuck's Trucks catalog says (2) pins are required per truck. Perhaps that's why I had problems. Has anyone ever installed these? How are they installed?
Can this be made from a simple pin? Perhaps a piece of drill rod, or something softer?
I dug into the parts manual a little further; in 1952, the F1 offered the A8C-7001A column shift transmission which calls out the 01A-7221 pins. Ford also offered the A8C-7001C center shift transmission, which calls for the B-7221 pin. This confirms the part number that Chuck @ Chuck's Trucks told me shortly after I posted my inquiry here.
A quick internet search shows this B-7221 pin is offered from several sources. The pictures all of these sites show looks like a case-hardened dowel pin.
The 01A-7221 is, in comparison, an intricate part...it has two diameters, the larger is hollowed out to accommodate the spring shown in the picture that you posted, and the smaller diameter pin (opposite the spring end) I'm guessing follows a groove.
It's been a few years, but I recall making one from a 1/4" bolt for my T87D. Cut off the threads and the hex head to factory length.
The original was in the shape of an hour-glass from wear.
Both the top loaders I have had apart, 1 pin.
one was a 1950,tother was a 51.
my latest take apart, the slot/groove the pin slides in( the slot in the 1/2 ball/radius part of shifter) was wallowed out, being a machinist,I remachined the slot bigger to a metric size dowel pin,opened hole in trans. cover to except bigger pin, so inspect the slot in your shifter?
Good luck at ya.
