Case 1370 White

[MCKS]

I have a Case 1370 White tractor. Borrowed from my in-laws. Don’t know a ton about it.
Ran it out of fuel. Spent a long time getting it fired up again. Ran perfectly fine while we bailed 10 acres.
Parked it for a week and it wouldn’t start again. Came back a week later, still wouldn’t start.
Assuming it lost prime again. Pumped it up, cranked and cranked some more. Little bit of starting fluid (not excessive). Finally fired.
Ran up to probably 3/4 throttle. Injector pump shut off and throttle had no effect on it. Kept running at high RPM’s. Finally pulled the fuel line and killed it.
Looked everything over, tried again same results.

Any guidance before I tear into it or send it off to someone?

I’ve been pretty deep into my 180 Allis with good results. But, by no means a mechanic.

Thanks for the help.

It sounds as if the inj pump control rack is stuck..
Remove the side cover on the inj pump, 2-10mm bolts.
Have someone pull and push the stop cable.. the control rack should move the 6 segments FULLY, left and right..
For future purposes.. ALWAYS LEAVE THE SHUT OFF CABLE IN THE RUN POSITION..

Thank you, I will check it out this evening and let you know what I find. Also appreciate the advise on the shut off cable.

Thanks for the advise. But it appears I’m a little lost. Removed the two 10mm bolts. But I’m guessing this is not what you were describing. Am I looking in the wrong place or is this a different pump than you assumed I had?

 

[thepumpguysc]

It’s the correct pump..
Pull and push the shut off lever while u look inside the pump..
The control rack should be moving all 6 of the cylinders..

 

[thepumpguysc]

Whatever you do.. do not put a screwdriver in any of the segments.!!
They are the equal delivery to each cylinder..

 

[MCKS]

Ok. Nothing moves at all inside there when I operate the shut off lever.

I’m not sure I understand what should be moving? The segments operate up and down by cam correct? What does the shut off lever control? Little different setup then my old Allis.

Is that picture current.??
U have all the mounting bolts off.??

Yes it is current. I do not have all of the mounting bolts off. My son started to remove the pump at his grandpa’s direction. I stopped him before he got all the way. The rear (between the pump and engine) mounting bolts are still in. The gear hasnt been touched yet. Everything is still in time.

 

[MCKS]

Any advice on where I could find a manual or diagram on the pump? The manual for the tractor covers removal, but nothing on the pump itself.

 

[thepumpguysc]

That’s because it’s TOP SECRET...
Is there a big plug in front of the pump.??
If yes, remove the plug and use a flashlight it look for the timing lines..
if u bolt the pump back up and rotate the engine BY HAND until the VERY TINY timing lines are visible..
Seeing you have the side cover off, rotate the engine until #1 JUST STARTS TO RISE & stop.. now look for the timing line..
If u can’t find them, lemme know..

 

[thepumpguysc]

It looks to me that #2 has a broken spring.???

 

[MCKS]

Found them and have them set lined up together. Did not have the cover off at that time so I cannot verify that #1 was starting rise. But i have dis-assembled yet so I can do it again. #2 spring is not broken. Must be the camera angle.
Still cant seem to see what the shut off lever should be controlling?

Maybe watch this short video. It will help you understand what thepumpguysc is explaining to you.

 

[thepumpguysc]

I can see how it could help.

 

[MCKS]

That helped tremendously!
Control rod is for sure stuck.
1st and second from the front injector plungers are stuck in the up position.
I have the pump off. The back partially separated. I cannot move the control rod. (Did not try very hard.)
Logic would say its the one that’s stuck one’s causing the problem. Still working on how or why.
Will dig back in after lunch and keep you guys posted.

 

[thepumpguysc]

They are 1 in the same..
Stuck plungers mean stuck rack..
Free the plungers and u free the rack.

Watched the video again and seen where the two are together.
Now just big hammers and chisels right?!?

You might want to consider sending the pump to thepumpguysc and pay him just rebuilt it for you. That way you know it will be right and it will not get damaged beyond repair. Injection pumps can be temperamental especially if you have never been through one.

 

[thepumpguysc]

Amen to that..
