800 case diesel injection pump trouble

My son has an 800 case diesel that has trouble starting.

We can take a side plate of the side of the injection pump and move the small linkage rod and the tractor will start and run fine.

What I want to know is how do I fix this problem. Or what causes the fuel shut off linkage rod to stick.

This is the American Bosh pump (single plunger pump)

do you use fuel conditioner? if not I would recomend doing this not only now but every time you fuel as this will lube and keep the entire fuel system in good shape also make sure all water traps are free of contaimation,also I have found due to the extremly dry fuel available now I will ocasonally add engine oil to my dsl, this not only will increase power it will lube the pumps internal workings cnt

I had that trouble with a Case 900B. When you take that cover off squirt some clean oil in there and then work that arm some. If that is like mine there is a cover on the back side too. Take this off and squirt oil in there too. They are supposed to get enough diesel from pump to lube the governor. But they get dry sometimes if they set for long periods.

I"ve been working with different fuel additives on my Cummins powered truck. Had good luck with Lucas but price was a bit much... now I use 2-stroke oil added to the diesel. Seems to run as well as with the Lucas (seat-of-the-pants dynamometer) and gets as good mileage and the cost is better (half or less).

Hope this helps.

Ken glad some one else has thought of the oil adding I even add used motor oil to mine and run through a filter on my pickup tank works great, as to the conditioner I still use it just to keep injectors clean and I feel I get more than my money back in increased power and fuel savings but that just my findings and opinion thanks cnt
