Wheel tightening torque (Triumph GT6)

[FrankG]

Hi

I am putting some Triumph Dolomite Sprint alloys onto my MkIII GT6.

Does anybody know the wheelnut tightening torques for the Dolomite nuts

Thanks for any help

a few seconds with google shows:
" The nut tightening torque with the 11.1 mm (7/16 in) diameter wheel stud
is 108 NM (80 Ibf.ft)."

Aren't GT6 studs 3/8" unf -- 45 lb.ft would be nearer the mark

Been looking through my collection of old 'Motor Trader' data sheets.
Unfortunately by the time the GT6 came out the magazine had dropped wheel
nut torques off its list. However previous Triumphs specified 38-42 lb.ft.
for 3/8" UNF studs and 55-60 lb.ft. for 7/16" UNF ones. 80 lb.ft. would
require wheel studs made from 75 ton steel (quite apart from what it might
do to the wheel) which IMHO is a trifle unlikely and just shows that you
can't believe everything you read on the internet.

I very much doubt it. The torque for modern 12mm wheel studs is normally in the
66 to 75 ft lb region. That would put an 11.1mm stud at about 60 ft lbs based
on the same grade material and similar thread pitch.

I don't recall the right value, but that sounds _way_ over the top for
a Triumph.

It's 66 lb.ft on an SD1 which has IIRC 7/16th in studs.

An 11.1 mm (7/16 in) diameter road wheel stud, Part Number UKC 5475 -
and nut, Part Number UKC 5476 - have been introduced on the Dolomite Sprint
model. These replace the 9.5 mm (3/8 in) diameter road wheel stud, Part

The 11.1 mm (7/16 in) diameter stud and nut were incorporated at Commission

Seems more than a touch on the high side, IMO. Best place to ask is probably
on one of the Triumph club's web forums. The TDC would be good, but it isn't
a Dolly, so maybe Club Triumph would be more appropriate in this case. Plus
as someone else mentioned, there might be offset differences to take into
account.

My Sprint manual says Road Wheel to Hub 3/8 UNF stud 48 ft/lbs these
are alloy nuts as well BTW.

Sprint wheels are mounted,supported and aligned using the centre spigot
and not the nuts. Nuts only hold the wheel against the hub in this instance.

The above maybe correct also for the 7/16 UNF - but my thinking an
extra 32 ft/lbs is an awful lot if you have alloy nuts.

ISTR that there's a possible problem with doing that as the wheels need
to be supported by the central boss rather than just the wheel nuts. No
doubt someone will be along who can shed more light on the subject...

The boss is for centralisation rather than support and not all cars use
the feature, The theory dictates the joint between the wheel and the hub
is a friction the studs shouldn't have any significant shearing or
bending loads. The key is to tighten the nuts evenly in stages using a
diagonal pattern using a proper "spyder" wheel brace.
It is however essential to the wheel nuts which seat properly in the wheel.

FWIW, in my experience the toolkit wheel braces seem to be made out of

chocolate.

Also the advantage of a spyder brace is it puts a much lower sheering
force on the stud when tighening/slackening.

Well, it will prevent putting a sideways load on the stud. Although doing
this is only likely to break the wrench...

As per service notes that's correct. Both are machined to fit. Also
alloy nuts which have straight sides (no degree bevel to align)

And BTW you should not fit Sprint wheels to the standard Dolomite this
is what the service notes actually refer to so one would have to assume
the GT6 would come under this category as well.

This probably explains why there always seem to be lots of Sprint alloys
around for sale very cheaply! Sorry mrcheerful!

Why on earth shouldn't you fit Sprint alloys to a standard car? I thought
the front hubs at least are identical?

I thought there was an offset issue with Sprint wheels on a Spit/Herald -
something about the callipers fouling? Sorry to be alarmist and vague but
I'd prefer to be safe when it comes to wheels, kinda fundamental to motoring

There is a problem in that the alloy wheel has to be supported by the
centre spigot- its not supported by the alloy nuts there only to hold
the wheel against the hub.


The caliper issue maybe another don't know.

Thanks for all the advice.

There is a couple of guys running sprint alloys on the GT6 in the TSSC club.

AFAIK there have been no problems

Quiller Triumph charge £25 each for sprint alloys, although I did not buy

Thanks, I have had a look, it appears my wheels are not dolly ones, but Stag
wheels at a guess (they came from a 2500 estate) Looks like I might try a
cheap listing or put them into scrap aluminium.

Triumph 2500S cars has Stag alloys on them as standard I believe - they
aren't worth much unless in excellent order but eBay is a good place to
dispose of them. Also, Retro Cars mag has free sale listings.
As for the price of Sprint alloys, it's often said that there are two things
for the Dolly that will never be rare, rear lights and Sprint alloys :-) Oh
and there's a nice Dolly discussion board on the Dolomite Reg club pages
that's worth a post or two occasionally
