2-105 turn up pump

[tom upton]

I have a 2-105 with 4800 hrs showing. I bought it cheap, took rusted out cab off, put some 4 digit fenders on it, new floor boards etc. We have a local pull with a 12500 class that my Son helps run. There are never many tractors in the class, usualy just my 1900 and one or 2 binders, so they talked me into taking the 2=105. So I went at it and put a bigger charger on it off of a 2nd gen dodge, and turned the CAV pump up, or so I thought? My question here is did I turn the pump up? I took cover plate off, removed the two small screws that hold a 1/2 inch or so thick disc up against a thinner plate that I turned 4 complete turns clockwise as looking down from the top of the pump. This was done the morning of the pull, and I really did not have time to test it out, but I did notice it did not seem to smoke much more than it did before. I go to the pull and get beat by my 1900, a 1066, and a D21. And not just by a little. It didn"t seem to smoke hardly at all even under full load. I am hoping someone on this forum knows a bit about these CAV pumps? Did I turn the plate the wrong way. Any help would be appreciated Thanks Tom

Need to know the pump #, suspect you have a later 4 plunger pump as the 2 plunger pump plate has tangs that will not let it spin. On either style pump the drive plate screws DO NOT need to come completely out, only loosened so the adjusting plate can be moved. I suspect you just put the plate back close to where it was. 4 plunger pumps have less adjustment range than the 2 10MM plunger head had.

My boy pulled a 1066 for a few years and in that one class if you did not have close to 200 horse you knew you were out of the money so to speak. He would see how many places they paid and how many entered that class to see if he finished last so he could get more back than his entry fee. We would set it close to 200 horse.

whites and olivers (such as 1650s and 1750's not older 770s and 77s and such) are terrible pulling tractors because they are so heavy and massive, but that makes them awesome farming tractors so you may need more hp

A flat blade screw driver and a 7/16 wrench you can make the old red ones scream!

Why would being heavy make a tractor not pull good? That should make it pull better than a tractor that weighs less...

All you need to do is loosen the two 12 point bolts. That disc you rotated, just needs moved a little. On the one side where that tab is, is a 1/2 or so slot. Depending upon the pump, you move that tab clockwise or counterclockwise in that slot. That is all the adjustment that is necessary. We have a 2-105 engine in our 1850 running around 175-180Hp.
