The spindle bolt thread is 1/2"-20

Roger - The first item on that list is incorrect. It should be #14-24 not 1/4-24. There is a difference.

Yes Ken, Seth Harbuck corrected that 11 minutes after Peter posted that list in 2009 :-)
In that thread you can also find a link to the Northern Colorado T clubs much more comprehensive list of Model T thread sizes: http://clubs.hemmings.com/ncmtc/Technical/Bolts_nuts_threaded_items.pdf

If it is of any help to anyone, the NAPA Balkamp Helicoil kit number is 770-3085.

I agree with Dan. If the lower threads are bad, chances are the top hole is wallowed out as well and needs a tapered insert, if not you are only fixing half of the problem. The Stevens tool is the best way to fix a front axle. Don't forget to clean up any excessive wear in flat areas where the bushing rides.

You need to be sure you have the helicoil tap true to the kingpin as you will likely need to tap it from the bottom of the axle. I set mine up on a drill press using a 1/2 inch diameter rod in the drill spindle for alignment. If the upper end is wallowed a bit, it can be shimmed with steel shimstock.

Another way to compensate for a wallowed out upper end is to put a few weld beads around the top of the kingpin (we used a MIG which didn't significantly heat the pin proper) and turn them down on the lathe to be a snug fit in the upper hole.

We took up 0.010 diametrical clearance this way as shown in the photos below...

I had to do a temp (for how long ??) fix. Living in an apartment and no garage. Top wollered out, bottom threads shot to heck. When I pulled out the bolts, somebody (dad??) put in some copper foil or tape. I decided some stronger was in order. Bought the cheapest, long feelers gauge set and trimmed down to size. When I got the bolt to go thru bottom a third of the way by hand,installed spindle and bolt tightened rest of the with wrench ( my dad would be proud). Eventually when I redo front springs I'll have it done right. Cured my wobble.

I saw the Stevens Front Axle Tool in use yesterday. Nothing beats having the right tool for the job. With it, you can even do the axle while it's on the car.
