IIRC, that baby is a full inch in diameter, which means it’ll take torque of over 250 lb/ft…charts show even a (weak) grade 2 bolt/nut that size will take at least 188 lb/ft. Rest assured, those Salisbury threads are FAR stronger than grade 2. I’ve seen figures as high as 500 or 600 lb/ft for grade 8 bolts/nuts. Couldn’t find spec in the Manual, though, so I torqued mine to about 250…plenty tight.

As strange as it sounds to write this, I have never seen a torque specification for these nuts, and I have looked in the Jaguar FSM and the Salisbury FSM. The closest thing I have ever found was for a Dana/Spicer 44 (essentially a Salisbury 4HA) rear axle used in 1950’s and 60’s Willys, Jeeps, Studebakers, Ford trucks, Internationals, etc. which calls for 250 ft-lbs. If you go by a bolt chart for SAE bolts of that size, the recommended torque can be 600ft-lbs. If you can’t get the slots to line up for the cotter key, and they are close, you can file a couple of thousandths off of the back of the nut in lieu of loosening it.

Ready to tighten rear axle nut on XK 140 but can’t find a torque spec to tighten nut. The nut is thin and requires a cotter pin after tighning. Can anyone help?

However they are on a taper, When new, if you sit the hub against the taper , you can’t pull them apart by hand. They would need to be tapped to get off. Like a tailstock on a lathe. If second hand [ either part] they need to be lapped together , Boring, tiring work Ideal for children wanting pocket money. , One needs to take the burr off the keyway edges with a file so it doesn’t catch when you turn , Then apply valve grinding paste and turn back and forth, Then turn 90 degs and repeat , and so on all the way around Remove and wipe/wash off the paste and you will be able to see how much contact area there is , Keep repeating until most of the area mates . Ideally one needs a 3/4" drive socket [ and certainly not a tube spanner ] and a very long bar…
