No room for new throttle shaft bushing

I'm back with the TQ bushing info. Don't mean to hijack your thread, but this thin tubing will probably work for your 2 bbl also. The reamer is from Kodiakcuttingtools.com. The part no. is 179661 and it was like 55.00 dollars. Ask for a catalog if you order one of these. Always nice to have another paper catalog. The thinwall brass tubing comes from Ace Hardware, and is K&S Precision Metal-part no 8136, 13/32X.014, you will have to cut to what you need. I put the tube over the smooth shank of a 3/8 bolt and cut with a tubing cutter, go slow as the cutter wants to crimp the tubing on the bolt. If anyone has a better way to cut this tubing let us know. I grind the peened ends of the throttle screws of with a Dremel tool. I get new screws from Fastenal, 4-40X1/4 Stainless Steel part no 72478, or regular steel-same size part no 32553. These screws don't have as large of a head as I would like to use, but they work-I haven't had one fail yet. Here again if anyone can find a screw with a larger head, let us know. You tighten the screws slowly while working the shaft to center the blade one at a time. I use red Loctite and peen the threaded end. This peening works best with two people, one to hold the base and one to do the peening. I use the same 3/8 bolt or another one mounted in a vise with the threads up. Position the head of the screw in that little cup and peen the end of the screw with a center punch.
I got a head of myself. I use a 9mm socket mounted on a 2-3 inch drill arbor, you will see why the extension later, I always ream the drivers side first because it is worn the most. Then install that bushing, then ream the pass side and install that bushing using red Loctite. I looked all over Lincoln for a 3/8X8 bolt to install the bushings, couldn't find one here, had to go to Beatrice- more of a smaller farming community, they had them. Again, back to the reaming, fill the 9mm socket with paper towel or whatever to just about the end, you will need as much of the cutting flutes as possible, go slow and in reverse as the video stated. When putting your shaft back in the base make sure you have everything in the right position. I'm sure there is something that I've forgotten, so post any questions. I have probably rebushed around 10 Thermoquads. Also if your shaft is worn really bad this will help but won't be as good as it could be. I always save all of the old TQ's for the throttle shafts. I've put Mopar shafts in the 9800 series GM Thermoquads.
