Little update on my rebuild progress...
I got myself an in-lb torque wrench yesterday! Took advantage of the Father's Day sales and got myself a nice clicker-type torque wrench from Mastercraft (the Canadians will know the brand well. Exclusively sold through Canadian Tire, these are very good tools and reasonably priced). It was 50% off, so I got it for just over $60. Not bad at all. Check it out:

The Mastercraft Maxium line is the "professional grade" of the Mastercraft brand of tools. They are almost up there with Snap On in my opinion, and definitely better than any shade tree mechanic would ever need. Most of my tools are Mastercraft. And 3/8" drive means I won't need to use adaptors to step down from a 1/2" drive wrench. Nice.

Adjustment range between 30-250 in-lbs is perfect for rebuilding a Paxton ball-drive supercharger.

Lifetime warranty... can't beat that. If anything goes wrong with the wrench, I can walk into any Canadian Tire store and get a free replacement on the spot - no receipt needed and no questions asked.

Even comes with it's own plastic case too! Sweet. (I know, I know... most torque wrenches come with their own storage case. Hey, it's a new tool and I'm excited!).

The calibration tag that came with the wrench shows this is a fairly accurate unit too!

So now it's about time to start the rebuild!
But before I do, I have to ask a couple of quick questions:
1. The assembly drawing that's floating around this site shows that Loctite (or Locktide... whatever the hell that is) is supposed to be used in various locations. Which Loctite did you use? Did you use any Loctite on bolt threads (ie. between the drive shaft and the ball carrier, on the impeller bolt, etc...) and if so, which Loctite?
2. What kind of assembly lube did you use? Did you just coat the various parts in Type 'F' fluid, or did you use a specific prelube? Did you do this BEFORE or AFTER establishing the proper turning torque for the impeller?
Always install the parts lubricated in F type oil not dry.
I use locktide on the bearings for extra securety they will not spin.
I do not use threat locktide on the bolts exept for the impeller bolt. I really do not want that bolt to come lose at high rpms.
Locktide is a sort of glue that keeps bolts from comming lose (threat locktide)
There is also Locktide for flat surfaces, I use that for the bearings.
