Ron,
I doubt if 180 is too far off as there is a lot of surface area even
if you think the nut is rather skinny.
I have the factory tool for this nut and the Tommy Bar for it is
about 2 feet long of which it bears my full weight when I am
tightening those things and I am no light weight either as I scale in
at 14 stone . They are frequently loose so get them real tight and use
some Loctite.

Subject: Rear Hub Lock Nut Torque?
Hi Gang!
Well I'm back in Ireland after my visit to Uncle Sam. Had a wonderful
time, especially being able to get to Watkins Glen. "Our" era of
Sports
Cars is in safe hands, judging by the quality and quantity of
'50s/'60s/
'70s sports/racing cars I saw there. Unfortunately, could not spend a
lot of time there.
Also, it was delightful to meet Gary and Chuck there, and later that
night,
Frank in Toms River. Thanks for the warm welcome, guys, and the very
kind
words later on this list. Hope you all have a most enjoyable Holiday.
My
apologies that it has taken so long to post this, but that dirty four
letter
word called w**k sorta got in the way. Have been mentally drained.
Also, while in US, I talked with Paul A., and got his kit. Hi Paul! It
is
extremely well thought out and made. (Carried the flywheel out and
back as
hand luggage. Talk about fun at the airport check-ins! Security at
Gatwick
really had a difficulty believing that it was not a landmine).
Presently, I
am getting the Sunny box cleaned by blasting, along with the rear
axle.
Everything is almost ready to go back together once I pick up those
bits.
This leads me to my question for the List:-
---------------------------------------------------------------
What is a proper torque for the rear hub lock (retaining) nuts?
---------------------------------------------------------------
The Mk 1 workshop manual I have just says "When the nut has been
tightened"
without any torque data that I can see; Haynes does not even get that
far.
So, how tight is tight? In "Tuning BMC Sports Cars", Mike Garton
simply says
(p.18) "Rear hubs also present a problem. They must always have the
bearing
lock nut absolutely tight."
Reason I am so concerend about this, is that the N/S/ bearing had been
turning
in its housing, (I have a replacement hub). DPO had used a cold chisel
to
tighten
the nut! I can't find a reference in the archives, nor on the 'Net,
bar one
which
suggets 180 lbs./ft. Now that seems way too much for such a skinny
nut. So,
what
do you advise, please?
Later,
Ron in Ireland
'59 Sprite "Oggibip".... almost with 5-speed.
