Keith, I'll keep a eye open for another tracta joint axle for you .
.

it makes you wonder why they did these things i cant say i found anything unusual in mine, the only thing i found of any interest was a shotgun bullet, but not unusual

Check out the change over point on the axle serial numbers as the Tracta joint is most likely a stray, used to replace a broken U joint half shaft.

The other thing is that the bearing used to support the Tracta joint on the diff side is a ball bearing and doesn't slide apart, unlike the roller bearing for the U joint that does.

Yes Arthur. I think the Tracta is a ring in along with the 061..... 1600 engine and freewheel gearbox. An 80" has been used as a donor.
Interesting point about the bearings.
I thought the early bearing was the ball and the later the roller and that rollers would allow the half shafts to come out easily like a series 2 for example.
However one of the donor swivels I am dismantling wont or wouldnt.
Roller bearing but the cage enclosing the rollers is on the inner race. Couldnt get the halfshaft out, broke the cage with the press.
Another roller bearing has the roller cage on the outer race. The inner race is smooth so allowing the halfshaft to be removed without a press .
This must be the later type and the one I would use for replacement.
Funny thing is I only have one part number for the roller race 244150.

That bearing has the sliding inner as a integral part of it, I actually brought one new years ago and realised that the bearing retainer had to come off, to get the inner portion of the new bearing onto the half shaft.

I know that I would have made up a strap puller to remove the retainer, I have made these several times in the past to remove Land Rover and Ferguson tractor wheel bearings from semi floating axles.

Strap pullers have the strap ends welded to the retainer, the welding heat swells the retainer ring and they then come apart easily.
.

With both these bearings the retaining collar has to come off to remove the inner race. Its just that with the one in the left photo the axle can be removed with the inner race and collar attatched. In the right photo the inner race holds the rollers so the axle cant be removed without removing the collar.
Even with your method of the strap puller welding to the collar destroys its function as the bearing surface for the oil seal so it will have to be replaced anyway. I grind through them.
On the other hand why have a seal at the end on the axle anyway, just let the diff oil mix with the swivel housing oil. Its all kept in by the hub seal.
Then you could reuse the collar you pulled with the strap puller as the welds would not matter. No seal.

The inner bearing on the Tracta joints is definitely different. But you are right, they should not be on an 86", they were only used on the 80". I believe that the inner bearing needs to be retained with the Tracta joint since it can come apart if not held, while a universal will stay together. The axle and bearing should come out if the swivel housing is taken off, then the bearing can be pressed off. In the series one section there is a sticky on parts numbers and I listed the part number for an alternative bearing in there when I did mine. The housing for the universal joint is also slightly different with more clearance for the joint but the Tracta joint fits into it, just the universal won't fit into an earlier housing.

Cheers,

TimJ.

The swivel housing that had the Tracta joint also had this early outer housing. On the left. No drain plug.
