That's actually the GOOD stuff. I mean mashed peas, sandwiches so dry and
tasteless that you need at least two pints to wash them down (that's my
excuse and I'm sticking to it). Spaghetti and meatballs with sauce that
must be made from ketchup. I spent two weeks in London without a single
meal that was memorable in a positive sense. The British Museum and all
the car stuff more than made up for it.
But enough non-tech.
I'm sure there's some opinion herein about differentials. I'm sticking my
Detroit Locker into Peyote and changing the drive ratio (from 4.10 to
3.70) at the same time. I don't have any of the special tools, so I'm
improvising a bit. For the pinion bearing pre-load, I added shims until I
got a tiny bit of end play, and then took out a .005" shim.
I did the ring to pinion engagement in the same manner. I added shims
until the roller bearings were tight enough so I could barely remove the
ring and diff assembly from the housing, then I swapped shims between the
two ends until I got no shake in the tightest segment of the gear
engagement. For anyone who hasn't played with a diff, the ring gear gets
tighter or looser as you rotate it because of manufacturing or wear
irregularities. I found the tightest spot, and then used that as my worse
case for setting tooth engagement. The depth of engagement is controlled
by shims that push the ring gear to one side or the other.
I do have a dial indicator that I could use to measure backlash as you
would with most mechanisms like this, but I don't have any idea what the
value should be for a Triumph diff since the manuals I have only cover
assembly with special tools.
Then I checked the engagement point with some Prussian blue on the teeth.
It's hard to tell where the engagement really is--there's not a nicely
defined spot like you'd expect. The pinion seems to be wiping along almost
the entire tooth, but at least it looks like it's not just at the top or
bottom.
I suspect that all of this is not so critical on a race car diff, where
you don't really care if it moans a bit. I might be wrong, perhaps this
backyard approach is going to cost me fifty horsepower and boil my diff
like a lobster.
Opinions and advice please.

You mean stuff like Yorkshire pudding (which gives new meaning to the word
"pudding") and Kidney Pie (internal organs should always be relegated to
the rubbish heap)???
