Cat 22 front idler part number is 1B306
D25U front idler part number is 6F9433
I don't know what the difference is.

Hi, Kaeson1972.
I think there were 2 different idler sizes for the U series D2s, a spoked one for Ag/drawbar work and disc one with a slightly larger diameter for dozer work.
Just my 0.02
