Nice. Like Cat power torque!

I am sorry I did not see this comment sooner I'm very glad that it worked out for you

Nice! Glad I can help

Let me know what you think!

awesome thanks! glad it worked! what tractor?

Jon Stevens Maple Grove Farms 4430

Oh yeah!!

You can put them to stock in half hour.

The 55 series should be a lot better because they had a higher torque curve capsule but you can try it let us know how it works

@@jonstevensmaplegrovefarms3754 ok I will thanks for answer

You should never take off a D3. LOL Give it a try let me know what you think.

@@jonstevensmaplegrovefarms3754 Seems to help, but it's not blowing much more smoke out than before when it pulls at the lower RPMS, can I go more or will that hurt something.

@@jeremyheitzig599 did you get the little screw flush or slightly lower then the jam nut? you hit the hand throttle forward you just pull against some Springs in the governor. Same thing if the engine gets lugged down it pulls again some Springs in the governor. All this is doing is allowing the injection pump to respond more quickly to changes You haven't changed the horsepower screw so it shouldn't turn it into a black smoker. A 50 Series might smoke a whole lot more because of the torque capsule inside the pump. But in the 30 series they only have like a 5% torque rise capsule. So my 8450 smokes like a pulling tractor when you touch the throttle but the 4430 doesn't smoke much. But compared to where they were to where they are now they are like a CAT engine in the tractor

The screw looks different but you would think it to be the same theory of operation. 50 series had a different torque curve, very much improved over the older series with the 15 speed tranny and using that to stay in operating rpms range you might not notice much?

Let us know how it goes.

If it has a set up like this on an inline pump you would like to think that it would help. But it does not change the peak horsepower. A pump shop can also change other things in there to give it a little more torque rise

@@jonstevensmaplegrovefarms3754 It looks to have the exact same pump and aneroid setup on it. It has lots of top end power, but it's always a real dog speeding up to 1750- 2100 RPM and if you are trying to run at 1800 RPM and you hit a tough spot, that bogs you to ~1650, it pretty much dies. Sounds like what you described in your video. I hope this will be a simple solution to my problem .

Give it a try let us know

@@jonstevensmaplegrovefarms3754 Thanks a lot for this video. I tried it on our 8770 this morning and beside the single "tamper - proof" screw (It used screws to hold down the cap on the aneroid), adjusted it no problem. Got lots of bottom end now and doesn't smoke any more than it did Been like 6 years looking for a video like this. Once again, thanks so much!

Awsome! Glad it worked!

I don't but its not hard. on the back of the pump by the oil filter housing is a square cap with 4 bolts holding it on. remove that cap then you will see a little thread and a jam nut. the jam nut is 10 mm. turn in for more power. a half turn or full turn is a good bump in power.

Jon Stevens Maple Grove Farms thanks!

The first thing I would check is the transmission pressure.. If you don't have a gauge set up, you can take a quarter inch lock washer.Put it in the vice and bend it flat so there is no more offset or lock to it. Behind the left battery box you'll see the valve housing and one nut at the bottom will be taller.

That is your pressure regulating valve. When you take that down a Spring and valve might follow. Keep cap upright so you do not lose the shims that are in there. With the added washer see if your p t o now stays on

If you had a leak we could say you are technically loosing some boost pressure, if it's a tiny leak can't see how it would effect power. Fuel usage would be dependent upon load and how its driven. Will use more fuel under acceleration, or responding to a change in load. Under same loads should use same same fuel you would imagine. Did tractors have equal power before?

@@jonstevensmaplegrovefarms3754 one has been on this farm for about 15 years. it always had very good power. The other one was purchest recently and was gutless and pouring smoke so we got pump/injectors done and new turbo. Issue was still there. so we decided to do an overhaul and during disassembly we discovered all boost press was bieng lost through crack in intake manifold. After overhaul it has way more power and less smoke. but there other one can pull a bit harder. Normally we dont like to put our tractors under max load but we were ripping up sod and the tractors had to pull hard as they could. I adjusted the aneroid in the overhauled one. The power difference is probably just in the pump i don't think ill bother turning the hp up. I dont think there is a leak on aneroid line I dont hear a whistle. But I do have thread adapters on the line due to having the wrong elbow on new intake manifold. it could possibly seep by

Will do!

This would help the mid range and bottom end power. For peak hp you take off the little plate with 4 bolts on the back of the pump. Some tractors you have to remove oil filter housing. There is a jam nut and screw, give it a half turn in. Honestly the 8650 had a good balance of power to weight. Everyone wants more power but its a good machine as is. The aneroid will help some

We just picked it up it’s gonna be running a 16 inch auger it doesn’t have quiet enough power to move wheat in that 105 foot auger without bogging down

55 series some models.still might have had some sort of aneroid system, but they also had a lot different torque capsule in them. Stock for stock a similar horsepower 55 series would have a lot more pulling power and mid-range than a 40 series

That screw only pushes fuel in before boost can get in, just makes some more smoke basically, not much hp gain but some

Yep, gets rid of the boost delay for a lot more low end torque.

In normal situations no but if a person now decided they don't need to downshift they can just let the tractor lug and pulled it like that all day long then yeah you could see excessive wear I had a few customers when I was out in central Minnesota we would not turn the Peak horsepower screw up. Because they were the type that if you gave them 25 more horsepower they would grab another gear and the tractor would still be hanging its tongue out Very noticeably harder starting? All of a sudden you have excessive blow-by like you were driving and then holy cow where did all that come from or you are driving it one day and you thought I don't remember the tractor having that much blow-by before More likely something happened because the tractor has how many thousand hours. It's just naturally at that wear point, or an injector could be bad causing damage to the piston, highly unlikely but a ring could have broke.

@@jonstevensmaplegrovefarms3754 It's was kind of a freek happening. I had the tractor at a shop to get the pto and drive clutches replaced, when he went to warm it up after he was done, it was just idling and all of a sudden they noticed it sounded different and noticed the blow by. It doesn't miss but does sound labored. It has 8400 hrs. I don't us it on heavy loads at all, just running a tmr, baler, 15'jd 750 drill, etc. I'm a zero till guy. I like your videos, and others that deal with regenerative ag.

All of a sudden and labored i would stop running and pull the pan and start checking bearings.

@@jonstevensmaplegrovefarms3754 oil pressure still good.. But the plan is to do a inframe over overhaul. Thank you for the quick response. I REALLY appreciate that.

Good luck! Might be out of frame if a bearing spun.

A 15/16 12 point deep well or a box end wrench should loosen that retaining nut.have never really seen any froze in the head so with that nut loose they usually come out. the dealer has a special tool for tightening the nut because you need to hold the injector at a specific spot. Or a couple box end wrenches kind of work

@@jonstevensmaplegrovefarms3754 Thank you for the response jon, I tried the 15/16 socket this morning but it did not fit.To small, i'm thinking an 1'' socket will fit.

Hmm, did you take that o ring off the top of the nut? Did you get them out?

@@jonstevensmaplegrovefarms3754 We are taking the head off to get re-surfaced. And the guy's at the head shop said to just pull it off carefully and they will pull the injectors out for us. Now I'm working on a leak under the steering wheel... Gosh it's tight in there.

Machine shops are usually really darn good to work with on that kind of stuff! I thought I had a video working under the dash there. It's tight but it ain't bad

Oh boy if I remember right you got to take that top little cover off where your return fuel line comes out of. You might close the fuel above the front axle in front of the front axle shut the fuel off if your tank is full so you're not just pushing fuel through but I believe with the top cover off you can roll the engine over and you'll see a little tiny Allen screw up here if you turn that screw in you increase the horsepower. It's a small Allen screw something like a 5/32? I thought like a half a turn was about 10 horsepower.

Does that tractor have an injection pump that is round? This would be on the tractors that had the inline pump

@@jonstevensmaplegrovefarms3754 yes it does😄thanks for reply

No oil will come out on that top if you take the 4 bolt cover off the back a little oil might dribble out.

@@jonstevensmaplegrovefarms3754 thank you I was worried I was going to lose gallons of oil

For more power or the tractor in.general?

Jon Stevens Maple Grove Farms just the tractor in general

@@collinmilam5691good engine, main hydraulic system, transmission, sharp turning front axle, easy to drive, comfy. at some point the pipes in the trans housing will start leaking and need to be split. seems like these tractors went to 10k hours with little to no trouble. once they start to have trouble in the middle it can get spendy. if a guy left the hand brake on you will want to flush trans housing and replace when it quits working. they are overall good tractors but for the money it wouldn't take much more to jump to a 6400 and then you would have a lot better tractor.

Jon Stevens Maple Grove Farms what about the power on them

How to “ turn them up” for say

Shouldn't have anything to do with oil/fuel transfer

@@jonstevensmaplegrovefarms3754 Thank you

Landlord has some land we need to clean up. Might have to break out the moldboard again
