Case 1845C Fuel Issue Help

[Flying_gage]

Hey all,



Really struggling on this. I have a 1995 Case Skid with a 4bt motor. This motor has the VE pump minus 2 injectors.



Here is the story. The weather was in the -20 range and it was running fine. The fuel then gel'ed up when the weather got colder. I crack the filter and added "diesel 911". It started up and ran fine after that. While running it after it gel'ed the filter started spilling hyd. fluid and I fixed that. Prolly lost 2. 5 gallons of hyd. fluid, (I add this for reference, I do not think they are related but that is why I am adding as much as I can). Added more hyd. fluid and continued plowing. The next morning, it was gel'ed up again and I did the same thing as before adding the diesel 911. Nothing. Puffed white smoke and then no puffing of anything. Cracked the injectors and no fuel to the injectors. I then bled the fuel system per the manual and still nothing.



I have made sure that I am getting 12v to the pump and my battery is good. I am at my wits end. The only other thing that I can think of is the pump lever is bad. I pumped it a couple times and it goes limp. It then takes a minute or so to build pressure back up in it.



Also, now I have no resistance anymore in the throttle if this makes sense. Whereas before, I could feel resistance now it slides with complete without any.



Damn I am frustated! Any ideas out there? I really don't have the money to spend to have someone come out to look at it and fix it. I also need to get it moving though...

Hi Pete! Are you mad enough to sell it yet? :-laf



Did you have the block heater plugged in? Or is it kept inside?

The LP going limp is normal if it builds up pressure. The other thing is if the line is frozen/ plugged from the tank, it will feel like that too. I would pull the line from the tank and check that first, make sure you are getting fuel all the way to the IP. If you think the shut off solenoid is bad, you can pull the plunger and spring out of it, and put it back in. You will have to shut it off with the lever on the side of the pump. (if it has one, I can't remember)

If you need to run the machine when it's that cold, you might want to invest in one of those "magnet heaters" You can stick it on the bottom or lower side of the fuel tank, it will help warm the fuel and not gell so easily.

Throttle problem sounds weird, did the spring fall off, or linkage come unhooked?

Good luck,

pete

Ptoombs,

Nah, not yet the damn thing is too productive!

I had a magnetic heater on the oil pan when this happened! It was stored inside, but it was butt-*** cold here! I guess just too much.

I am getting fuel to the IP, just nothing out of it. I have cracked the individual lines going to each injector at the pump and nothing comes out.

The throttle linkage is still in place. Hasn't come lose.

Any thoughts?

If you don't want to sell, how about we try to make a trade. I sell new ones.

 

[Flying_gage]

I would love a 95XT! Those still have the 4bt right?

 

[PToombs]

Rowdy, are you going to deliver and pickup the old one? :-laf



Maybe the shut off solenoid went bad? I know it's rare on these, but it's possible. You can gut it to to see if that's the problem.

I wonder if something in the pump let go? Even with the solenoid off, you should get some fuel out of the injector lines. That would explain the throttle, governor spring broke maybe? I've never heard of one breaking in all my time on diesel sites, but stuff happens.



You probably should invest in the standard block heater and put the magnet on the fuel tank. It's easy to install, good access. Better than on our trucks! :-laf

95XT, 4bt, 95(?) hp, 2 speed, 11 mph, super hydraulics, big bad boy!

 

[Flying_gage]

Yeah, that 95XT has me drooling whenever I see one. But dangit this little 45c really works at everything I need. If I need a bit more weight, I throw some tractor weights on and it works fine.



The loader arms are down and it is a ***** to get at the pump. Any thoughts? I figure I am going to have to pull the radiator and what not to get in there. It looks like it will be a ***** to get to that shut off from the side as it is under the pump and angled.



I am wondering the same thing on the pump? I mean there is zero fuel coming out and I have pulled all the lines off the pump. The throttle thing weird. There is no resistance.



Are these little pumps really pricey?



Well, I appreciate it tons. I have a manual but it leaves a bit to be desired. Any helpful hints would be appreciated. Sounds like I am going to have to tear into her.

 

[Flying_gage]

Key switch..... I tested another "hot" coming off the switch and it showed 12 volts. But fuel solenoid wire.



I owe it to my friend who is a helicopter pilot and A/P. He thought it was a long shot but told me to test it.



Thanks for the responses!

Just my HO, I work Heavy Equipment for the USMC and we are taught when manually pumping the lift, keep hitting the lift pump lever till you cant move it any more. That normally means the line is primed. That is the advice I've gotten for machines ranging from the early '80's to current date.

John,



Thank you for your service... .



On my 96 12v that is what happens... . I guess that is normal though on these little 4 cylinder cummins. Go figure.

Pete, a second, or third , thought. Check the plugs where the harness goes together behind the cab, above the bell housing. They are known to corrode there, and the pins rot away, breaking contact. It may run now, but if you get a chance, check those plugs. Sometimes that will cause the same problem you had.

 

[Flying_gage]

Will do. I have the harness pulled apart and am going to dig into that anyway... . Appreciate it!

 

[PToombs]

4th thought! :-laf If the battery is good, you can hold the "up" lever and crank the starter to raise the arms. I've done this a few times and it's worked good.

We have not talked dollars yet. Maybe I could.
