Talk Morgan Forums Morgan Sports Cars Morgan Plus Four, Supersport & Plus Six (CX & CXV Generation Vehicles) Torque setting for spoked wheel nuts

We've gone through all this dozens of times over the years. There really isn't any point trying to establish the 'correct' torque to use when doing up the wheel nuts, not least because they have a self-tightening action when on the road anyway. Threads of this size and pitch can take enormous amounts of torque before deforming so all that is needed is to tighten them up by hand and then give them a whack or two.

Exactly. I love the way morgan supply a not fit for purpose spanner that needs bending

Which after you bend it as recommended, won't fit in the tool tray

Totally agree Tim, I only nip the spinners up (not tight) but always need the spinner tool & breaker bar to undo them.

Of course, you are right as the self-tightening due to wheel rotation will make breaking torque much higher than tightening torque.

Tool tray?! What tool tray. I got something that looks like a wash bag which contains the spanner and a can of sealant.

My newly deformed spanner will fit my wash bag fine! I intended to heat the spanner up before I start manipulating it to avoid over stressing the steel.

Tim, I am new to Morgan ownership, hence my question. Whilst it may have been discussed at length in the past, it is not something I am familiar with. I have worked on many vehicles over the years, two and four wheels and this is the first time I have come across a safety critical securing nut which requires ‘ a whack with a hammer’! Frankly, I find the notion totally absurd in this day and age but that it seems, is that.

I use this tool Andy, I only nip them up, not tight at all (supplied by wheel widget) but much easier for removing the spinners. I never whack them.

Mine has 70mm AF retaining nuts, not spinners. I have purchased a 70mm AF socket and have a 1m long breaker bar. I intend to do as you, Tim. I really cannot bring myself to whack anything with a mallet or hammer!

An entirely understandable sentiment, but I would urge you to consider what you would do if you had a puncture whilst on a remote lane in France well out of cell phone range and you didn't want to have to wait for recovery? It's happened to me twice. Those nuts do up flippin' tight, and some sort of shock to reach the breakaway torque is going to be needed. You are not actually hitting the car after all if you use the spanner.

The eared spinners of course were specifically designed to be directly clouted with a lead hammer and personally I like a bit of patina, to my mind it's all about the traditional appeal of Morgans.
