MG MG Y Type - YA Front Hub

I have replaced all the rubber parts in the front suspension of my 1950 YA.
This required removing the front hubs.
Unfortunately I cannot found any information on how tight to tighten the front hub nuts.
Could somebody please give me the correct torque setting or procedure.

Thanks in advance
Gordon.

What information are you looking for Gordon? Have you looked in the workshop manual yet? Need a copy? They are part of the suite of books on the Y/YT manuals DVD book or the YB DVD book - https://www.mg-cars.org.uk/imgytr/stores/yzpublications.shtml

I have an Instruction and Repair Manual but I cannot find either a torque setting for the hub nut.

Gordon. Cars of this age were not designed to have everything torqued up. Mechanics were expected to have some idea of how much to grunt when tightening something. There are often tables to be found, compiled by helpful people, but for older cars they are mainly bases on the yield strength of the parts involved and for something as large as a hub nut thus would be far more than is needed. Basically tighten it as much as you can and then back it off until you can get the split pin in, or grunt a bit harder until the next castellation lines up.

Nailed it Ian!

Thanks Ian.

That's what I needed to know.

All the manuals just say tighten the nut!

Hmm-This all leaves it wide open for under/over tightening--depending on the feel of whoever's doing it.
The method of tightening it up then backing off leaves it possible to be too loose and compromises the strength of the assembly
Best idea is to tighten the nut to around 45/50ft/lb then on till the next splitpin hole but don't exceed 70/75ft/lb getting there-
So 45/50 then reset your tension wrench to 75 and use it to creep up checking for the next pin hole after the 45/50---If you reach 75 before you get to the next hole, try swapping the nut off the other side ,they usually end up in a different spot

specs for an MGB is 40-70 and I've heard of 80 being the recomended max.spec for standard T type stub axles, but that's getting up there a bit-

Tighten until the bearing just starts to bind and then back off one castle nut face, it should be OK for 100k miles

Yep I agree with Mr Bellum , always worked for me .
