Yeah every time that box goes "GRAUNCH", it makes a bunch of little bitty metal 
bits that settle down in the bottom of the case, right down there where the 
laygear lives...
Yeah Jeff's fast, he's finally figuring out how to use those torques he's got!

We change the gearbox oil after every race weekend on Jeff's TR3, per Glen's 
advice.
 
It's cheap insurance, and it works.   And we all know how fast that TR3 is 
now...
 
Thanks Glen.

Oops, one more thing to add to my pre-race prep.  Every race   weekend, really?

Since we have been thinking about gearbox's. The Stag layshaft was changed by
Triumph to try and make them last longer due to the additional torque of the V8.
They added needle bearings in place of the brass thrust washers at each end and
an additional bearing  in the lay gear at the end where 1st gear is. Has anybody
tried this set up in a racing box? Does it help in the wearing of the layshaft?


The addition of needle bearings means that the spacing of the box inside
where the lay gear rides is greater. The needle bearings being thicker than the
thrust washers. This means that the Stag box is different inside. 
I have been
able to make a tool that will cut the inside of a TR box to be the same as a
Stag. I plan to build a box using the needle bearings. Don't at this time plan
to put another bearing inside the lay gear. If I make the lay gear deeper
inside, I am afraid it will not be hard enough for the bearings to ride inside.


Before doing all this, has any body gone down this road before. If so what
has been the experience? 
Also any body with thoughts chime in. Is it worth the
effort?
