D7 3T Track adjuster

[Bill Walter]

Got a question from a friend about track adjusters on a 3T. It appears that some one modified the original housing. If that is possible.
Piston and housing measurments are; OD; 2.8015
ID; 1.7500

Any help would be appreciated; Bill Walter

Is the adjuster a Cat unit. Pictures of Cat units are in the parts book. I have a D7 3T series with after market hydraulic adjusters. Since my machine is all together I will try to describe my piston. The piston is just the adjuster with a smaller turned down end on the end of the piston, the seal just sits on this.

If you have this seal and this after market setup, the seal is the same as Allis Chalmers used.

Contact me at wabco_rob@yahoo.com and I can give you the name of a place that you can send this seal to. They will match it up if this sounds like the adjuster arrangement you have.
