There is no numbers, plate or identifying characters. Hoping someone can help me identify it.  ------------- '40 AC B - My Pappy always told me "Use your head for something other than a tack hammer!" I did. It makes a great 16 pound sledge hammer. |

You know, This forum comes up with the damnedest things. I was fortunate to be alive through the life of the B but I have never seen this pump. Correct me if I am wrong but it looks like it is attached to the pto through a universal joint? Usually the B pump is attached to the rh side of the PTO - facing front. Could you give us a picture further back so I can get a better prospective. A real mystery. Thanks for sharing. Take good care of my favorite. Good Luck! Bill Long

You know, I think DiyDave may well have hit the nail on the head. It powers a loader therefore is an after market pump. Yes, it probably runs off the B PTO and is mounted on the seat. Since the loaders require much more oil flow then the B AC pump produces this was added. Thanks Dave. Correct question. ihscout, Check the make of the loader. Going there - if still in business - may provide answers you need. Again take good care of my favorite. Good Luck! Bill Long

Got out & scraped on Pump on WK Crawler . Hydreco brand pump . 1.5" lines coming in & OUT. WK had a c frame bigger than the one on my HD6 EP. Must have had a 12' blade . was told they used it to push snow near Grants Pass Oregon. My K is set up similar only it looks like it was farm crawler ..

I couldn't find a tag or anything on the loader either. The problem was the front seal was leaking horribly and I've had it apart before. Guess I used the wrong substance to repack that front seal so this time it's fixed for a while longer. I used a couple of those plugs that you use in a tire patch kit and wrapped them around it, tighten the seal nut and have run it for about 4 hours with no problem. Thanks all for your input ------------- '40 AC B - My Pappy always told me "Use your head for something other than a tack hammer!" I did. It makes a great 16 pound sledge hammer. |
