john deere aneroid adjustment.

good morning guys thank you for tuning in today the John Deere aneroid on the 30 and 40 series tractors especially like the forty four thirty and forty six thirty and your forty four forty and bigger in the forty series the forty two forty and thirty are not included because they had a separate fuel pump but any of the old John Deere tractors with the inline fuel pump the old a series or P series they had to aneroid on him and that aneroid was basically a smoke limiter it would not allow when you hit the throttle you're just basically pushing against the spring and the governor housing and the aneroid would limit how much the rack moves based on how much boost its building that helped reduce a lot of smoke out the exhaust and helped their attempt to make the engines more fuel efficient but it gave the motors a very weak bottom and they were they were turds under 1700 rpm they're just even 1800 you had to stay at PTO speed to get work done out of them you adjust that aneroid turn that screw in now you have a cap motor you have full fuel as soon as you tap that throttle that rack moves you get black smoke and that sucker is pulling hard I do a tremendous amount of field work with the 46 40 and the 84 50 at that 17 1800 rpm range doing full tillage work moldboard plow I do a lot of mobile plowing at that 15 at shoot even if it's good going plowing like in the spring when the soil is very soft I'll jump up into fifth gear and just idle back to 1,400 rpm 1500 rpm everything's moving really nice and the tractors just rolling right along and not use it any fuel it really wakes these tractors up helps them out tremendously so let's let's go do one and see how simple it is and how in five minutes you can take your favorite old Deere tractor and make it that much better alright so here we're at the engine here is the aneroid assembly out on the injection pump they're just a little nut up here this this warranty wire we called it if that wire is snipped then obviously you lose your warranty but I think the warranty ran out of this tractor literally just shy of 40 years ago and so yeah so we loosen this nut we take that off and then under here you've got this little nut inside and then this brass piece this bugger might be in there awfully tight that all it is you can see the top collar is turning separate from these threads so that top car is just a little Jam nut and you can see the protrusion how much that guy's just sticking out a little bit so all we got to do is we just take that little screw and we just turn him in it's kind of hard to do this one-handed but I'll manage people bare with me so I just turn him in a little bit I get that guy just under flush that's about where I like to run it at and then I retighten the little Jam nut then I put my nut back on top Snug him up and that's it that is that simple and now the tractor is live and alive and ready to work in that mid-range if you want to change the horsepower that's under this cover you take this cover off on some tractors the oil filter housing is right here so you'd have to take the oil filter housing off but you pop this cover off it's a ten millimeter socket down there with another screwdriver bolt and you turn it in or out whether you want the power up or down and so that's a that's on this on this Charter is super easy but yeah that's where you change horsepower and then you had some other bumper screws here and stuff to change how the tractor reacts but but that's it that is the John Deere aneroid right there makes it the cat motor she's going to pull hard and go from there guys I hope somebody can benefit from this video thank you for watching
