Hi,
Those are THE questions, aren't they?
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:
Dennis Vessey - Quaife gear kits for Triumph TRs
|=20
|=20

|
|
|=20
| |=20
Dennis Vessey - Quaife gear kits for Triumph TRs
metatags generator
Vesseys Triumph TR Dog-Engagement Gear Kit - developed with Quaife
|
|
|
Note, if you decide to go that route, please contact me, I've been in conta=
ct 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.
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 ther=
e was no production scheduled.
Failing that option, there's the "Dolomite Close Ratio Gearset". This consi=
sts of a different input shaft and main 3rd gear along with the correspondi=
ng 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 yea=
rs, and it is really really good. Note: for the best total gear ratio optio=
n, get a later TR6 gearbox with the 16-tooth 1st laygear.
Now, the drawback to the helical gears is apparently excessive thrust force=
s and they effect the layshaft thrust washers as well as the layshaft needl=
e 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 workar=
ounds to compensate for excessive end float.
Note too that because of torque multiplication, the layshaft needle bearing=
s 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 s=
tock setup. But even with that setup, the layshaft still gets pounded and y=
ou need to keep an eye on it.
As you may know, a lot of the racers are gravitating away from the stock an=
d/or modified Triumph gearboxes mostly because the quality consistency of r=
eplacement parts is all over the place and you need to know what you're get=
ting to spot the differences. That said, frequent oil changes and paying at=
tention to the detritus in the oil, you can stay ahead of problems.
If you're going to build a good gearbox, it will cost you as much or more t=
han some of the conversions out there, hence a lot of folks switch to Toyot=
a/T5/Rocket, etc.
Hopefully you'll get other good advice on this list, but that's where I'm a=
t 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 w=
hich are the same as the old Muncie "Rock Crusher" and there is a gearset a=
vailable with a 2.43 1st, 1.63 2nd, 1.23 3rd and 1 4th which is pretty clos=
e to the Dolomite Sprint setup. And the gearbox is 70 pounds which is reall=
y close to the stock box. Also, if you want to dish out more $$$, Gear Vend=
ors has an overdrive that bolts to the T-10, I haven't researched that enou=
gh to see if there are any particulars, but it is an option, albeit around =
$3k. But you get a BRAND NEW overdrive. Just sayin. A drawback to the Super=
T10 is that you will need to make or source a bell housing, but that is do=
-able with a combo of a trashed TR gearbox, a competent machinist and more =
$$$. ;-)
