I'm finishing up the assembly of the rear axle on my '63 Midget getting ready to hang it underneath the caer & I can't find the torque on the hub nut anywhere in my shop manual. (Its that huge nut that holds the hub to the differential case, #2 in the diagram below)...can anybody point me towards the torque setting?

140 lbs Tony.
 
Where'd you guys find it in writing?
 
Page 152, Chapter 8, Haynes.

Pinion drive flange retaining nut.............140 lbf ft.


Woops #3 is only maybe 30 lbs and has a retaining washer. No reference.
 
I have it listed as the bearing retaining nut. Still #3 130 lbs. I know that is what I torqued mine at! I did it on the floor all by my lonesome. :smile:
 
Barry - where'd you find that 130lbs in writing?
 
Remember: #2 in the diagram at the top of the thread.
 
Good Golly Man! It is supposed to be REALLY tight; put a strong arm on it and lean on it. Many people have an aversion to the tab washer and will use high bond locktite. However, I think you would be fine to use the tab washer.
 
Leyland Cars Workshop Manual page H.5

I know that I originally found it somewhere in my hardback Sprite book when I torqued them down. That book is at my parent's house.

Nope! That's not for #2 in this diagram - its for the nut holding the pinion oil seal in place....totally different bolt:

I'm beginning to think its not torqued but just like Jack & Trevor said, "reall tight".
 
No Tony, that is the nut. What is it?? Like 1 1/4"? The only one like it. One is left hand threads and the other is right hand threads. 140 lbs... Find out for sure before you get her put back together. It is listed as number 2 in your pic, but in my book it is listed as number 3.
 
I do not think you'll find it listed anywhere. You are not stretching a fastener here. You are drawing the bearing in against the shoulder. Just make it really tight, but that nut is really soft metal, so I do not think it would handle 140. Maybe 60. I make it tight and use a dab of threadlock AND the tab lock washer.
 
Tony, I will look at the name of my other book tomorrow. It is a pretty common book and I know that I found the torque setting in it.
 
Yes the nut that holds the hub on the end of the axle tube. I can assure you that it can be over torqued because there is a forum member here that did not know the the left was left handed threads. He managed to remove it by stripping the threads in the nut.
 
It seems that depending on the book and or website, the nut is called different things. What other nut would be torqued to 140 foot lbs on the axle? This has to be the only one. I will look tomorrow and see what the other books says.
 
The pinion nut on the nose of the differential. In that case I think it is required because on the spacer setting the preload.
