D4-6U "spring part"

My D2 parts book calls it a sleeve. found it in the equalizer spring page
Cat has mine for $39.29 :jaw:

A few years ago I bought a D4 7U that had that piece missing on one side, not only was it gone but the tabs on either side of it were gone too. I cut a pair of tabs out of 3/8" plate, welded 'em on and took a chunk of 1 1/2" plate, carved a new piece, drilled the hole and installed it.

As I recall, the D4 J, T and U models all used the same piece (probably with different part numbers). You don't want to run without one on each side over the spring. .if the critter rares up it's possible it can flip the machine over.

I am sure I have 1 or 2 of those footballs that you need. Give me 1 or 2 days 2 find it, then u could come and pick it up.I am in Hollister.

I just used a piece of pipe with a grade 8 bolt thru it--will that work? what is the function of the football shape?

Since the track frames oscillate and the spring does not in that plane, the tapered shape of the roller allows it to maintain better contact with the flat end of the spring & promote more even wear.

thanks rotorbob!

my dad works in San Juan Bautista, so if I am able to catch a ride from him picking up the part should be no problem!

Cool, just send me a pm when u r ready 2 come.
