Technical How do you stake a hub nut?

[SillyBilly]

I have a new hub nut for my Multipla and have torqued to 70Nm + 62 degrees. The diagram shows how to stake the nut so that it doesn't unwind. The old nut had an L shape cut to allow a piece to be bent into the groove in the drive shaft. I couldn't re-use the old nut. The new nut has no cuts so what do people do?

you must use a new nut,IIRC i used a chisel on the last one i did of that type

Hi
Thats what I expected but do you just depress it into the middle of the groove or try to cut through it at the correct end?

Big chisel, big hammer, big whack is the way to do it - hit it in the centre of the groove and it'll bend in and lock the nut.

Are you sure that the old nut was cut?It may have split when it was hit to lock it last time

Ok then that is what I'll do tomorrow morning unless someone says otherwise! I just don't want to spoil a £4.50 nut.
Yes both were clean L cuts about 3mm in each direction.
looking at the Fiat CD The Nota in Operation 4450C10 shows a picture of how it should be.
