MG TD TF 1500 - TF rear hub nuts. Tightening torque

Hi all,

I soon will be helping a friend replace a TF rear axle oil seal. (Left hand side.)
1. I assume the rear hub has parallel splines and has to come off using a puller?
2. What torque wrench setting should we use when reassembling and tightening the castellated nut?

Bob,
Here are a few more that might be useful and worth keeping handy.

brand new shaft and hub you may get away with it.
150 foot pounds on used ones.
UK cars mainly disc wheels and there are no NEW brake drums/hubs
see archive "Rear hub nut on TF"

Do you need to pull the hub from the axle shaft to replace the oil seal? Can't you pull the hub and shaft together, so that you can inspect the condition of the splines on the inner ends of the shafts? Even the slightest trace of twisting there will lead to certain failure.

A factory wire-wheel hub puller screws onto the hub like a spinner, and then a central threaded shaft presses out the axle. I made a similar tool by drilling out the center of 2 old knock-offs, and welding nuts for a central shaft.

I would recommend 150 foot-pounds for the axle nut, as with steel-wheel cars. Consider my Dave Clark/MGT Repair improved axle shafts - not a single reported failiure, even after 30 years!!

You still have to pull the hub off the axle to replace the oil seal,even if you could take the axle and hub out as one unit.150 ft/lbs on replacement.

Thank-you all.
I will use the 150 ft/lb. The thread is 7/8" which is bigger than the 3/4" Spridget diff-pinion thread. The latter is meant to be tightened to about 130 ft/lb when a solid spacer is used, so 150 sounds about right.
The 85 ft/lb suggested by PJ and shown in Rod's image might also finish up at 150 when taken to the next split pin hole. Maybe that is the reason for the range of numbers given. I will use various thickness washers to get the 150.
Thanks for your help.
