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?
