Purchased an auction lot with a bunch of Farmall and Cat parts. I was able to ID by myself or Google a lot of it but some numbers remain elusive. Hopefully some of you might know what I'm looking at. 

Some or all may be for sale too, depending on if I could use them for the Cats I'm around. 

 

1. Washable oil filters, not sure what for. 2. not sure 3. not sure 4. pony clutch shifter 5. Input shaft D47U? 6.? 7.? 8.front half of input shaft D47U? 9.? 10.? 11. looks like input shaft coupler D47U. 12.? 13.? 14.?

looks like the part with 2 bolts and grease nipple bolts to the plate. no idea what it's for. the 2 flexible? woven things look like some kind of wick.

Pics 1& 2 are indeed washable oil filters. Pic #3 no idea. Pic #4 a generator block off plate or a direct electric starter block off plate. Pics #5 & 6 starting pinion drive side cover with clutch/brake collar yoke looks like fits D2 & D4. Pics # 7, 10, 16, 18 all related, D4 clutch pilot shaft, input coupling, trans input shaft & bearing housing for trans input shaft. Pics #8 & 11 front mounted Cat hydraulic drive, both pieces related, the shaft splines into the crank pulley adapter hub. Pic #9 no idea. Pics #12, 13, 14, 15 no idea but they definitely all go together. Pic # 17 no idea, may not even be Cat. Pic #19 pony motor electric starter drive pulley cover. Those are my best guesses 😬
