Cat 22 Rollers

Anything of a used tractor or new or any ideas would be useful. Thanks.

Cat 15, 22 and D2 Rollers will interchange , What is Your problem ? Roller worn out , or Shaft loose ? ,Bellow seals for D2 are rather expensive and Bushes much Harder to deal With , Brass bushings in 15/22 are easily made and Fitted and Shafts can be Made and replaced ,[ was a Good article here a few Weeks ago with Measurements for "J" series D2 ] the D2 'U" Shaft is a different fellow, I haven't rebuilt one but feel the middle hump could be cut separate and Pressed on . Anyone done that ? You will require 4 Single flange and 4 Double flange [Single go on front and rear ] as per R2/D2 Book ,But 15/22 Books show all single . I would use double Myself in Middle LJ

The front rollers are completely worn out and the back inside rollers could be build back up. But would be nice to try and find a new set. [attachment=36774]image.jpg[/attachment][attachment=36775]image.jpg[/attachment][attachment=36776]image.jpg[/attachment]

Not sure if this applies to the Twenty-Two but D2 owners have the option of fitting D3 rollers new.

Can I just rebuild up the current rollers by welding them back up? Because from the research I've done it look like these rollers are going to be hard to find.

You can, and there's a Cat guide on here in the stickies on how to do it. Basically you weld 2-3" pads on opposite sides of the roller which avoids overheating and thus shrinking the roller bore. You then do the same on another roller, and work your way around them all. By the time you make it back to the first, it's cold. Cat says you can turn the rollers in a lathe after building up if you want to, but also says it's unnecessary. A lot of folks just weld around and round the roller and then get the bore bored back to spec.

I and a few others have setup a water bath for welding the rollers---about 1/3 of the roller bottom is in the bath cooling it--and as Neil said just do a section at a time and alternate to keep the heat down---i just used a grinder to take any real high spots down on the weld and they wear down fairly smooth after a few hours of work
