[Healeys] Torque for Hub Locknut and Securing Nuts

[Bob Spidell]

Al,


Good question(s).

I've never seen an official torque value, but for most cars it's an obscene amount (i.e. >=150ft-lbs).  IMO, you torque as tight as you possibly can, which won't be possible unless you have a suitable socket (I sprung for an "official" socket, which if I recall came from Hemphill's).  Given that--and correct use of the locktabs--you shouldn't have any problems (the hub bearing is an interference fit and would probably stay on on its own, for a while at least).  Since the locktabs are mild steel they will compress a bit, so the more tension to start the better.


> 2) Securing Nuts (the five nuts that hold the hub extension)

I believe the "official" amount is 60 ft-lbs.  I have aways used 100ft-lbs, which is what's called for in most modern autos for lug nut tightness.  Also, I do reuse the locking nuts, but I clean the threads and (re-)apply blue Locktite and have never had one loosen (Locktite has become a religion for me ;)
