Hey quick question, I have an IH S1900 with a DT466, I was noticing the IP has no Android diafram?
I know it's an MW Pump because of the cast codes.
And from all I know it's a factory truck and engine?
Seems kind of odd.
I adjusted the screw under the 10mm Allen plug on top and adjusted the gov springs 4 clicks apiece.
There is a very noticable gain in horsepower and overall responsiveness.. though still know smoke!? Not at crank, rev or under load I can't even get a puff? I assume it's because it has no Android? Does it still have an adjustment under the cap on the back of the pump? Rack travel adjustment?
Thanks

That is a strange one. The rack stop should be behind that big nut on the back with safety wire. It could even be that nut is the adjustment.

Yea it doesn't appear to be very common from what I can find on the internet.. which is very little..
I'm curious what the benefit of this pump would be? Maybe it's an ag application? I know it's is restricting the potential of my 466 I do believe..I'm going to mess around with it tomarrow some more.. it's a project so I'm not worried to terribly much about it breaking though I would prefer it not to.
What is your opinion on removing the screw all together underneath the 10mm Allen head? I don't tow anything and don't plan on it persay.. I drive it around like a big pickup truck for the most part.. but even with that screw turned out as much I I think it can without contacting the housing and turning the gov springs in 4 clicks appiece, it picked up some power but not a whole lot.. I can't get it to smoke unless I'm in 4th gear at 15 -20 mph and hold it to the floor then it's only a quick puff. Hah
Oh I meant aneroid not Android my phone auto corrected woops.
I want to get this pump maxed out to it's full potential without upgrading yet. Then I'd like to do a turbo and intercool then injectors.
I just want it to be quick for what it is. I'm not trying to tractor pull or drag race it lol
I'm thinking around 300 maybe more hp and the more torque the better. Do you think it's achievable with this wierd pump? Or am I going to be forced to a p pump? Anyways thanks for the info.
I also have to idle it down, after adjusting the springs it idled up to 1100! Which believe it or not makes it shake alot less hah but still too high I'd like 750.

Not much benefit at all to run that pump. If you can max out the fuel on the back of the pump, it will wake up some. Do you have any pump numbers? If it's less than a 10mm pump, it's not going to do much at all. Taking out the screw on top will just make it smoke more at low rpm.
Getting 300hp from that pump will not be easy. It can be done with some real big injectors and if the pump is 10mm.

Alright appreciate the info! I have some pictures of the id plate on the pump but the picture didn't turn out well enough to read. I'll have to take a couple more.
I assume the nut on the back of that pump would still be an adjustment for the rack. I doubt an engineer would design a one off pump with out adjustability. But maybe they do?
Am I right in thinking that I should buy bigger injectors first before upgrading the turbo/intercooler?

If you can, just note the numbers after PES6MW***. Those 3 numbers tell you how big the plungers are. If it's a 100, you have 10mm. If it's 950, they are 9.5mm
