 Topic: Injection pump issues 2800 engine
Posted: 10 Jan 2017 at 6:45pm |

Just bought an 840b loader. History unknown but looks to have been worked pretty hard. It has the 2800 non turbo motor. It ran fine when we unloaded it but started acting up and then dieing after we started playing with it. It had an electric lift pump in it. Checked fuel flow and changed filters, still acted up and died. Hot wired fuel shutoff solenoid and continued to do the same thing. Would start right up then die within seconds. I removed the ball check valve on the top of the pump housing and it ran perfect. Used it for maybe an hour, worked great, shut it down, and now I can't even keep it running on either. Time for a pump rebuild? Or what am I missing?

Sounds like you need a pump rebuild.

That's what I was afraid of. I thought the ball trick would but me a little more time than it did.

Knocking the ball out of the return fitting will buy you some time, but it will need to be serviced. If it still dies after knocking out the ball, blow the return line out going back to the tank. It will stay running as long as it's got an open return path, and a good fuel supply to it.

I had the same thing happen on my 185 a few years ago. I felt stupid because I worked and worked on all these technical angles when it was a moth stuffed in the fuel line. I have the fuel jell up kind of nasty at times and clog the lines too. I had fuel flow. Just not enough. I mean, come on, why would a moth commit suicide in a fuel tank? How'd it get in there? But I'm just saying, before you start tearing away at hard to fix things, make sure you have full fuel flow. There's also two one-way check valves in the manual primer that could be broken. All this is real easy to look at before you did like I did, and pull off the fuel injection pump.

Well, I got it running today. I took the side cover off the pump to make sure things were still turning and first step to timing it to take it off and had lots of fine crud come out. Took the top off the pump and had lots of crud in there too. Flushed it out with clean fuel and it started right up and ran great. Don't know how much more crud will find its way out of the pump, but hopefully the new fuel filters will stop more from getting in. Seemed like fine crud instead of anything important busted, but imagine I am still looking at a rebuild, just not today....

The "crud" is pieces of your governor ring coming apart.

Exactly! The crud you see looking like plastic chunks, or coffee grounds is the disintegrated flex ring in the pump. It WILL need serviced soon. You can run it around lightly like it is, but if you just assume you've fixed it and keep using it, you will end up costing yourself a lot more to rebuild the pump since it will now start making metal filings inside the pump housing, and that will cause abnormal wear.
