Over the years I have also made all the adapters to push/pull with. Found my CAT pressure gauge the other day that I need. Has 4 scale ranges for various push/pull rams.

I am working on a 5E/22 tractor. Is there any specific specs for that model or would D2 be OK?

Neil, should read 5E R2 same as 22

I don't know if I would press that gear on to 25 tons, let alone 20 tons.
Seems an awe full high tonnage for such a small part?
If CAT lowered the sprocket spec from 15 tons to 10 tons.
Then I would be thinking what's good on the outside is good on the inside?
Just my random opinion.........

Well just to answer this question I took a spare sprocket shaft and bull gear, not perfect factory new bore and mating surface, put them in in my big shop press- 75T. Pressed to 25T with no problem, turned around and took them apart, that was 15-18T to separate. I measured the distance that gear moved on the shaft and that was approx. .062. I think the two mating surfaces were not ideal. The taper is what holds the pieces together not the nut, that is there just to prevent things really getting loose.

My .02, i'm going for what Cat says.

I agree! Thanks for the experiment!
