Odd rear hubs

After a year or so out to build a house I finally managed to get back to my NP Super Major at the weekend.

While taking the wheels off I noticed that the rear hubs are different.

One side looks like this;

The other side look like this;

We have another major and a 'skeleton' for spares and those both have the second type shown above therefore I presume this is the right one.

Mainly just out of curiosity I thought I'd ask if anybody knew what the one in the first photo is from?[/img]

Hi
That seems to be a common thing on a super major. one I have here in Canada has an odd one and I anserd a post for a guy wanting to know if they swapped over like this in the U.S.A on another forum.
I Think it must be to do with the diff lock being fitted and used roughly at a guess but maybe Brian could tell us with his knowledge of tractors in there working days

.
I wonder even if the other majors did it as well and we just don't notice because the shaft was replaced with the correct one

.
Regards Robert

Can't say that the dif.lock was a problem, it caused more problems in the area of bull gears and pinions.

The thing that caused halfshaft failure over here was strakes on one wheel on all the Major range. Steel wheels also overloaded things.

People could have had bearing failure or damaged the seal area before Speedy Sleeve was popular.

We have had old Major based loading shovels in the past and they have had the slot on one and dots on other. I would guess they had been changed when in heavy use early in life. The Shovels probably weighed 5tons plus and must have increased wear.

Thanks for the info, and your thoughts. Seems its not such an uncommon thing.

Now to decide whether to change it or not.
Half of me says if its not broken don't fix it.
The other half says I've got the right one for it should I change it before I start painting?

Hi David yes its interesting that you bring it up then others have the same thing.
if it was mine and a working tractor I would leave it if you are restoring it to show then change it. unless you want to leave it with the odd working modification or battle scar for posterity. i've seen some guys do this instead of straight out of the box concourse

Combination of filler and disc cutter!
