The conversion to ball bearings sdeems very interesting. What size of ball =
bearings can be used? Doesn't it weaken the part on wich the countergears a=

Nice summary! I don't have much to add other than the Quaife gearset uses s=
ubstantial needle bearings inside each of the gears, much larger input to m=
ainshaft needle bearing, steel thrust washers within the stack. Work of art=
. Layshaft still uses semi-stock bearings.=20
When I blew up my tranny I ended up going with the Quaife and really like i=
t. No synchros to break, shifts are lightning quick, gear ratios work well.=

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
[ http://www.vessey-classic-car-services.co.uk/triumph-gear-kit.htm#.XQjuu3=

metatags generator=20
Vesseys Triumph TR Dog-Engagement Gear Kit - developed with Quaife=20
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.=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 ther=
e was no production scheduled.=20
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.=20
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.=20
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.=20
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.=20
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.=20
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 $$$, Gear Vend=
ors has an overdrive that bolts to the T-10, I haven't researched that enou=
gh to see if there are any particulars, but it is an option, albeit around =
$3k. But you get a BRAND NEW overdrive. Just sayin. A drawback to the Super=
T10 is that you will need to make or source a bell housing, but that is do=
-able with a combo of a trashed TR gearbox, a competent machinist and more =
$$$. ;-)=20

<p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;font-family:"He=

omite Close Ratio Gearset". This consists of a different input shaft and ma=
in 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 la=
ter TR6 gearbox with the 16-tooth
1st laygear.</span></p>

<p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;font-family:"He=
lvetica",sans-serif;color:black">Now, the drawback to the helical gear=
s 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 s=
pin the thrust washers and wreck the case. There are some workarounds to co=
mpensate for excessive end float.</span></p>

<div>
<p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;font-family:"He=
lvetica",sans-serif;color:black">Note too that because of torque multi=
plication, 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 so=
urce) that is set up for the double bearing. I've had Quantum Mechanics ins=
tall the double bearings, they seem to work better than the stock setup. Bu=
t even with that setup, the layshaft
still gets pounded and you need to keep an eye on it.</span></p>

<p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;font-family:"He=

are gravitating away from the stock and/or modified Triumph gearboxes mostl=
y because the quality consistency of replacement
parts is all over the place and you need to know what you're getting to sp=
ot the differences. That said, frequent oil changes and paying attention to=
the detritus in the oil, you can stay ahead of problems.</span></p>

<p class=3D"MsoNormal"><span style=3D"font-size:10.0pt;font-family:"He=
lvetica",sans-serif;color:black">Hopefully you'll get other good advic=
e 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 t=
he same as the old Muncie "Rock Crusher" and there is a gearset available w=
ith a 2.43 1st, 1.63 2nd, 1.23 3rd
and 1 4th which is pretty close to the Dolomite Sprint setup. And the gear=
box is 70 pounds which is really close to the stock box. Also, if you want =
to dish out more $$$, Gear Vendors has an overdrive that bolts to the T-10,=
I haven't researched that enough
to see if there are any particulars, but it is an option, albeit around $3=
k. But you get a BRAND NEW overdrive. Just sayin. A drawback to the Super T=
10 is that you will need to make or source a bell housing, but that is do-a=
ble with a combo of a trashed TR
gearbox, a competent machinist and more $$$. ;-)</span></p>
