I am making progress on the front end rebuild of
my 606, but have run into a new problem. I
rebushed the front bracket and have a new pin that
is 1.75" I can get the front axle on, but when I
go to attach the link arms of the axle underneath,
they are under extreme tension to get bolted up.
If I attach the rear axle link first the axle hole
is at the wrong angle(pointing slightly at the
ground in front of the tractor.

I am thinking I will have to reduce the diameter
of the pin where it goes through the axle to
relieve this pressure when the link arms are
bolted up. This will give a sloppier fit in the
pin axle interface though.

Has anyone had experience with this?

Should those axle link arms be under some pressure
when bolted into position?

Does anyone know the factory diameter of the
factory pivot pin and axle pivot hole?

Thank You

I looked at parts page for 606 and 504.They use the same pivot pin. I have a 504 and looked at it but cannot measure pin dia. in place but it appeared that it would be 1.75" . Axles are similar though axle number is different due to 606 axle bracing yoke being longer due to 6 cyl. engine vs. 4 cyl. in 504 . If you have a new pin and bushings from Case IH then it is the right one. There should perhaps be some tension when you bolt up the axle bracing yoke to the underside of the clutch housing, but I would not think it would or should be much. Do not put a smaller dia. pin in the pivot. Perhaps you could heat and bend the axle bracing yoke in the vicinity of the ball to make things align better.

The pin and bushing I put in were not IH parts. I had them made. The pin is slightly oversize 1.77". I did this because the holes were slightly elongated about .035", so I think I could take a little off the pin. I thought of making an offset bracket for the ball to the yoke, or a spacer for under the clutch housing, but this really doesn"t solve the problem up at the pin interface (it may after it wears in.)

If the pin fits into the bushing easily enough, then I think you may have other problems. Maybe that new bushing was not bored straight?

I think the problem lies in the bore of the axle. It was elongated at the ends and tight in the middle with the current pin. In fact I had to do some honing to get it through. I believe there was more slop with the original pin both in the bracket bushing and in the axle, that combined with wear let everything mate up easily. I am going to turn down the axle part of the pin a little .025-.050" and see how it goes together. It is definitely better than When I got it. Lying underneath I noticed the pin was made out of 1.5" regular old pipe....pretty scary, and pretty loose.

Do you think it would help to lower the weight of the tractor on the wheels when trying to hook up the axle yoke?

Is there any order to attach the yoke?

Maybe you should consider replacing the entire front mounting bracket. Kind of sounds like the one you have now has been cobbled up one too many times.
