I'm rebuilding my tranny cover. In replacing the clutch pedal shaft, Is it acceptable to use a tension pin on the shaft for the pedal and slow speed notch instead of a solid pin ?

Original pins are also peined over. Personally, I wouldn't use tension pins anywhere on a T as the best and smoothest of them vibrate and shake like the sheep dog that just climbed out of the ditch. You sure don't want to lose a pin into the transmission , or lose control of your transmission and clutch ! Others may have a different opinion.

Thanks, That's why I'm asking,. I saw one of the Model T DVD's on rebuilding the cover, and he used a tension pin. Wasn't sure

Rest assured a solid pin is worry free.

When you think about all the jamming your foot can do on that low pedal. Or the brake pedal ......when you are standing on the pedal to try to stop when some stupid in a modern dives in front of you.....just as you are throttling down to that stop light ahead.

You will appreciate the time taken to rivet that solid pin, a hollow thing there isn't the better choice

In our club one of our members had a solid pins in his pedal cams and even one of them broke. All of a sudden there was no action when that pedal was pressed, and he had a car full of people in it also.

You don't want this to happen to you. No way! Safety first, especially in this important area.

I would not use spring pins in place of the rivets. They're not nearly as strong and are lible to shear off. A friend of mine had a spring pin in his low pedal which fell out on the covered bridge tour in September. I had to run him up to a hardware store to get a bolt to get his car drivable again. Once you replace the worn cams and pedal shafts you'll never have to take it apart again, so there's no reason to use anything else other than the rivets.

I saw one come loose as Rich as stated. Was not a pretty sight!

I hadn't looked at the low speed pedal and shaft on the 18 here. I didn't see the roll pin in there. One day I noticed it worked loose and wanted to fall out. I wired it in place until I could get a solid pin and set it. Duh, Duane. That's why the pedal was a bit loose on the shaft.
Roll/expand/hollow pins are strong and good for what they do but not really for our uses here. They do take on "a shape" on installation and will get "molded" a bit. Any movement/rotational torque of the parts adds to the "molding/shaping" of the roll pin.
Perhaps carry a few sizes for emergency use in your toolbox. Just to get ya back home.
IF I had a penny for every roll pin I've put in, I'd have 50 bucks or more!
