The flame revisited

Maybe, I would suggest checking the timing as suggested in your other post. Even if that is right the advance in the pump may not be working correctly. Does your jumper hose have a restrictor valve in it? Even if you were nearly using all the hydraulics that the pump can produce at full flow and pressure I do not think it should load the engine to the point it shoots flame. Even if the IJ pump is turned to max delivery it still only delivers the fuel needed to sustain the load and
RPM called for by the governor. If using the hydraulic pump on that tractor really takes that much power you should be able to find what is getting heated up to disperse the heat created to use all that power. What model is it?
You are running through a transmission check in the manual in your other post, tell us what you are trying to diagnose?

The timing is set to factory specs lines are dead on . I have 2 other tractors here that will also throw a flame just not quite as much as this one . And yes the hose does have
Restrictor in it . I had a spare one when I put the hose together so I put it in . Transmission shifts fine hydraulic pump has always been a little slow compared to any of the other tractors Ive got I figured after 59 years its probably getting weak . I have randomly lost engine power changed filters didnt help the others were clean not sure thinking just an obstruction in the fuel line or even a little ice .it was also 30 below zero the last time I had it running . Tractor has always threw a flame as long as Ive had it . Finally got warm enough to get some work done on things and the tractor Has power again like it should . The injection pump isnt that old but it was a cheap eBay pump to start with . Thought maybe since its going to be about 30 days before I can farm maybe have the pump checked just to see if it does have any issues
 
After seeing the hydraulic test load, the exhaust shouldn't have a red flame like that with a less than 25 HP load. None of my Powershift tractors do that just using the hydraulics. I'd suspect static timing setting and/or wrong pump advance curve setting.
 
I can make it throw a flame if I just run it up to high idle and.no load . I guess I better send it in and see what bubba has does with his trusty screwdriver and pliers .
 
(quoted from post at 22:47:12 04/11/23) Do to the flame do you think it would be a good idea to send the pump off and have the fuel delivery checked and reset?

I would have the injectors checked, as well.

Have you verified there's no restriction anywhere in the air intake system?
 
Everything is good as far as restriction nothing plugged
. I think bubba might of just gave the screw a good 5
turns . Probably a young kid they love smoke
 

No matter WHAT Bubba did with the ''smoke screw'' that doesn't come into play until rated HP and fuel delivery are reached/overridden.

Monkeying around with that will have NO effect on a lightly loaded (20 or 30 HP) engine.

If you ''overfuel'' a diesel engine at light load it will simply speed up, with NO dramatics at the exhaust stack.
 
Well its been like that as long I have owned it .
Replaced the injectors With reman John Deere
injectors didnt change anything at all same flame
same smoke as always it was easier to start for awhile.
Im sure the new injectors look just like the old ones I
pulled out . I still think that pump is pulling way to
hard and it always has
 

''I still think that pump is pulling way to
hard''

Remove the hydraulic pump coupling at the crankshaft damper pulley and start it up, warm it up a bit and rev up the engine and see how it acts.

You can also pull the transmission disconnect lever.

That will leave the engine running by itself, with no hydraulic pump or transmission load.
 
I will do that . The disconnect lever is seized cant get
it to move . I really dont think its in the transmission
because when ever I use the hydraulics it pulls the
engine hard the transmission shifts fine even below
zero
 

Dunno what you may have seen or what was done to those engines, but the bottom line is that simply turning up the ''smoke screw'' will have NO effect until the engine is heavily loaded.

If you pour more fuel into a lightly-loaded diesel in good condition it will simply speed up.

But you are free to believe what you want to, I'm DONE with this.
 
I have said ten times the pump is pulling way too much
horsepower . The picture with the flame is with the
pump hot. needle on the far side of transmission
temperature gauge . When you cycle the lever driving
its like you dropped a 3 bottom plow . We had 20 and
30 below weather for almost Month with snow and
wind in between even during that time the
transmission shifted fine and no drag . Need to check
transmission pump flow Is next on my path to the
answer.
