This hub looks different

[Redman]

Got this black hub from an ebay seller, was listed as being from an 80 850G.

I know there were some design changes (mostly 82 and 83 and current OEM replacement, not bothering to discuss that here) but that they are all interchangeable.
And I have seen different ones fom different years, with different material, but otherwize looked the same.




Compared here to a current OEM replacement one.

There are some dimensional differences.
Namley the pins are shorter, and the main body is thiner (is a plate rather than being cast).

The pattern of the pins seem to be the same, and the splines seem to be the same.






Any comment?

Anybody recognise this? Look like what would expect in 79 or 80 850G?
1949 Ginsue tractor?

>>Later Note
Maybe I should also say that it came from Canada.

I saw a post on this awhile back, but can't seem to find it now in a "search". I seem to remember the older style driven hub with the nuts on the back were discontinued (recalled?) on the chance they may come loose and cause everything to come to a real quick halt. I bet one of our senior members will chime in soon.

Probably came from a 90's cruser They are supposed to be interchangable ???

The one on the left that uses nuts to hold the studs in place, is the 79 style spline which was recalled. I have the same one in my 82 850G.

p.s. the early hub used different plates to retain the hub. if you intend on using it, you'll need to clean and re-locktite the studs, then make new plates to retain it to the wheel.

If that doesnt work out for you, I have this nice one from a 80 850GL. Will sell the entire diff for 60.00 plus the shipping. Has 18,605 miles on it.

Chuck, We are talking about the hub in the rear wheel.

Hum. In all the discussions I have seen over the years about rear hub/splines (since 2005 when pushstarting Steve Giblets GK and hearing it go grunch crunch), I have been aware of the hub having been made of different materail and being different colors. But did not know about a different style.

okay, that seems to be what this is.

Someone sold you a part that was removed as part of a recall. Freaking stealership profiting by selling a part they were paid to remove.

Thanks. Thanks Again. The voice of wisdom and knowledge.

So, yes, the one you showed is like this one I got here recently. So, we can call this the "early style" or the "79 style" (that I did not know existed).

So, you are saying that this "79 style" will fit in the later wheel and will fit the splines on the rear drive. But where it will not completly interchange is related to those retaining plates.

And the concern about the nuts on the studs.

Will have to ponder this further.

THanks again.

Dave, I have the recalled spline in my 82. I removed the nuts, cleaned and loctited the threads, then re-torqued the nuts. if you are worried about it, clean up the threads, torque the nuts and have someone MIG the studs and nuts together so they can't ever come loose. you could also drill the stud-nut combo for a bit of safety wire, that should work as well.

on the later style spline (non recall), the hub retaining plates fit in the groove. on the early style, the retaining plates sit on the surface between two studs. if you make up new retainers to use the early style hub, please account for the fact the hub rocks back and forth in the wheel's bushings. you don't want the retainers to smack into the studs when it does rock.

OH...I Got the matching one for the differantial here too..

Good luck selling that final drive Chuck. I had a similar one that took me over a year to GIVE AWAY. Those units are as reliable as door stops so nobody needs one, plus they are heavy so shipping costs more than the part is worth.

It fits in the 15.95 if it fits it ships boxes from the post office...shippings not squat. Already dry fitted it in a box earlier just to see if it would fit and it does.

How much padding room is there?
