Throttle return spring replacement

This is an older thread. Don't be afraid to start a new one.

There were several styles of throttle bellcrank assembly but they are all similar. When Ford put that arm on, they likely used a punch & hammer tool that smashed the pin and expanded it into the hole for a tight fit, much like riveting. The pins tend to be flush on both sides. Some have a bit of a dimple on one side where the pin was installed. It's hard to see it unless a person cleans all the crud off down to the metal on that arm. A person can use a roll pin going back together or use some welding rod if you choose to.
 
I've got a broken spring on a '29 Tudor and this thread is exactly what I need to show me what to do. This is an excellent forum with very helpful members! Thank you! I'll send some pics as I progress.
 
roh1332, the trick to getting the assembly back on the car; 1) Spin it over and load up the spring. Tie the arm to the "harp". I use a wire-tie. Don't get carried away, you will bend it. You just want to hold it (unless you have three hands). 2) Slip the unit up under the cowling with the floor panel removed. 3) From here you can hold the assembly with one hand, and start the bolts holding it to the bellhousing (2 bolts). 4) Snug down the bolts. 5) you can now cut the tie-wrap with sidecuts, or wait till the floor is in. Remember, it is goin to come up (spring up) because of the load, with nothing attached to it at this point. 6) you can put the floor in now, and then connect the rod on the engine side of the firewall.
 
I have the same problem (broken throttle return spring). I can see the pin (I think).
Do you have any suggestions on how to drill it out (drill size, any cautions...)
And where did you get a replacement pin?

Thanks.
