Hub Nut Torque

Quick question - how tight should the hub nut be? I recall the manual does give a torque reading but always wary of stripping a thread. Is it sufficient to merely tighten as tight as possible with a standard socket wrench and secure with the split pin?

Your Series MM hub nuts should be as tight as you can get them with a socket bar, remembering that you have to line up the nut to fit the split pin. There is no specific torque in the manual. Anti clockwise on the left.

Thanks Mike. My manual (which is an original red covered "MM & series II" manual) gives a setting of 50-55 for torque wrench on front hubs, but I think I'll just go as tight as I can with a standard socket. Cheers

Its only taper bearings that need a real torque figure and then backed off to apply pre load. Plain bearings should be "FT" :lol:

I can't find a torque setting in my manual, AKD 530A. What section is it in?

So FT = Finger Tight???

Mike, the figure in under "General Data" in my cherished old workshop manual. But I think the figure may refer to the later seperate brake drum hub on the later Series II's, as no figure is given for MM.

The torque settings in the manual do refer to the A Series hubs.
There is a lot of info on those sheets which is not in the later manuals. Any chance that you could email them to me as an attachment please?

Sure Mike, be happy to, Might take me a little while to scan them. It is an excellent manual, which reads as if designed for Morris service agents, not the home repairer. Lots of info about part number changes and part modifications.

If I find one on Ebay locally would you like me to get one for you and mail it across?

Cheers

It looks as though the Australian manual may be different to the BMC version. If you could track down a copy that would be great.

OK Mike, found one for you on Ebay here. Still a few days to run but currently only at $2 (a bit over a pound). Once I get it I can mail it over to you.

Hi all, just replaced the lower trunnion on mine. Got round to putting the hub back and checked the torque setting... :-? If I torque the hub up to the right setting then it's locked solid, even on taper bearings, this can't be right ? The hub is free if I tighten it enough to get the split pin through, any tighter and you can feel the bearing startign to bind. Any advice? Cheers

surfmike.. you mention taper bearings.. does this mean you have disc brake conversion? if so you will need to tighten them up to a different value.. if you do have a disc brake conversion, which one i.e. modified marina hubs or the ford based disc kit?
