I=E2=80=99ve been racing my tr6 for over 15 years and gave up,on the =
synchro box due to the inability to get good quality rings. Swapped to a =
quaiffe dog box and ended up buying another one from Vessey and a third =
from bustuck . Having experienced several counter shaft needle bearing =
failures which can be very costly I have developed a box with ball =
bearings on a fixed lay shaft. Does involved a bit of machining but as I =

four years of solid racing the ball bearing are still perfect. Not for =
everyone but bullet proof.

Hi,
=20
Those are THE questions, aren't they?
=20
Okay - Quaife has a straight-cut gear set that uses dog-rings, no =
synchros. Big $$$, 1600 UK pounds. Quaife just ran off a set and the one =
source that I know of in the UK can get them:

=20
=20
=20
Note, if you decide to go that route, please contact me, I've been in =
contact with the vendor and I'm trying to place an order for this =
gearset. Maybe we can save some shipping if we get a couple of sets.
=20
Note too that Bastuck has dog box gear sets including one using the =
J-type overdrive. When I contacted them last fall, they had none in =
stock and there was no production scheduled.
=20
Failing that option, there's the "Dolomite Close Ratio Gearset". This =
consists of a different input shaft and main 3rd gear along with the =
corresponding layshaft gears. You need to work the case to get these to =
pit, but they work great. These are helical gears. I've used this setup =
for around 20 years, and it is really really good. Note: for the best =
total gear ratio option, get a later TR6 gearbox with the 16-tooth 1st =
laygear.
=20
Now, the drawback to the helical gears is apparently excessive thrust =
forces and they effect the layshaft thrust washers as well as the =
layshaft needle bearings. If you make torque and you have any end float =
for the layshaft, you will spin the thrust washers and wreck the case. =
There are some workarounds to compensate for excessive end float.
=20
Note too that because of torque multiplication, the layshaft needle =
bearings on the 1st gear end of the layshaft get beat really, really =
hard. One fix is to install a double bearing on the layshaft (or buy a =
new one from Moss or another source) that is set up for the double =
bearing. I've had Quantum Mechanics install the double bearings, they =
seem to work better than the stock setup. But even with that setup, the =
layshaft still gets pounded and you need to keep an eye on it.
=20
As you may know, a lot of the racers are gravitating away from the stock =
and/or modified Triumph gearboxes mostly because the quality consistency =
of replacement parts is all over the place and you need to know what =
you're getting to spot the differences. That said, frequent oil changes =
and paying attention to the detritus in the oil, you can stay ahead of =
problems.
=20
If you're going to build a good gearbox, it will cost you as much or =
more than some of the conversions out there, hence a lot of folks switch =
to Toyota/T5/Rocket, etc.
=20
Hopefully you'll get other good advice on this list, but that's where =
I'm at right now (too). The Quaife gearset in the TR gearbox seems like =
the most "vintage" solution, but ALL of the options have pluses and =
minuses. In the spirit of full transparency, I'm also looking at Super =
T10 transmissions which are the same as the old Muncie "Rock Crusher" =
and there is a gearset available with a 2.43 1st, 1.63 2nd, 1.23 3rd and =
1 4th which is pretty close to the Dolomite Sprint setup. And the =
gearbox is 70 pounds which is really close to the stock box. Also, if =
you want to dish out more $$$, Gear Vendors has an overdrive that bolts =
to the T-10, I haven't researched that enough to see if there are any =
particulars, but it is an option, albeit around $3k. But you get a BRAND =
NEW overdrive. Just sayin. A drawback to the Super T10 is that you will =
need to make or source a bell housing, but that is do-able with a combo =
of a trashed TR gearbox, a competent machinist and more $$$. ;-)

Gearset". This consists of a different input shaft and main 3rd =
gear along with the corresponding layshaft gears. You need to work the =
case to get these to pit, but they work great. These are helical gears. =
I've used this setup for around 20 years, and it is really really good. =
Note: for the best total gear ratio option, get a later TR6 gearbox with =
the 16-tooth 1st laygear.<o:p></o:p></span></p></div><div><p =

style=3D'font-size:10.0pt;font-family:"Helvetica","sans-serif";color:blac=
k'>Now, the drawback to the helical gears is apparently excessive thrust =
forces and they effect the layshaft thrust washers as well as the =
layshaft needle bearings. If you make torque and you have any end float =
for the layshaft, you will spin the thrust washers and wreck the case. =
There are some workarounds to compensate for excessive end =
float.<o:p></o:p></span></p></div><div><p class=3DMsoNormal><span =

style=3D'font-size:10.0pt;font-family:"Helvetica","sans-serif";color:blac=
k'>Note too that because of torque multiplication, the layshaft needle =
bearings on the 1st gear end of the layshaft get beat really, really =
hard. One fix is to install a double bearing on the layshaft (or buy a =
new one from Moss or another source) that is set up for the double =
bearing. I've had Quantum Mechanics install the double bearings, they =
seem to work better than the stock setup. But even with that setup, the =
layshaft still gets pounded and you need to keep an eye on =
it.<o:p></o:p></span></p></div><div><p class=3DMsoNormal><span =

k'>Hopefully you'll get other good advice on this list, but that's where =
I'm at right now (too). The Quaife gearset in the TR gearbox seems like =
the most "vintage" solution, but ALL of the options have =
pluses and minuses. In the spirit of full transparency, I'm also looking =
at Super T10 transmissions which are the same as the old Muncie =
"Rock Crusher" and there is a gearset available with a 2.43 =
1st, 1.63 2nd, 1.23 3rd and 1 4th which is pretty close to the Dolomite =
Sprint setup. And the gearbox is 70 pounds which is really close to the =
stock box. Also, if you want to dish out more $$$, Gear Vendors has an =
overdrive that bolts to the T-10, I haven't researched that enough to =
see if there are any particulars, but it is an option, albeit around =
$3k. But you get a BRAND NEW overdrive. Just sayin. A drawback to the =
Super T10 is that you will need to make or source a bell housing, but =
that is do-able with a combo of a trashed TR gearbox, a competent =
machinist and more $$$. ;-)<o:p></o:p></span></p></div><div><p =
