Air Cleaner

I don't know what the interchange is but you might be able to identify other applications by looking up the element part numbers and see what other applications apply.
Most of the air cleaners were made by Donaldson Corp. so you might have some luck shopping by dimensions.
The 7U did not come with a dry type air cleaner although there were plenty of after market units installed.

Looks like that air cleaner, is part of air cleaner assy, 9m1828, also used on 59a and 63a 922's, 68e and 91g 112 graders.

Thanks Old Magnet and Josh I drove up to Pasco WA to Perkins Slavage yard this afternoon found lots of 11 inch air cleaners but now 10 inch ones . He looked on his micro fish and said 9M3598 only fit D4D 78A and 922B 59A both of which I own . The 922 is out at a hay stake to load big bales I'll need to go out and look at it but I think it's the same. PS Has anyone been to Perkins salvage yard lots of old stuff I,ll take the camera next time if anyones interested nice cat 15 that runs don't know how much?
