Injection pump question

Posted by Chadd on December 10, 2004 at 09:28:02 from (155.92.196.199):

Our 966 has the original American Bosch injection pump on it. About 2 years ago, a cylindrical piece with a screw head on the back came loose and then fell off of the back of the injection pump. When we got the tractor, it was cranked to 110 horse. Ever since that piece fell off, the total horsepower seems similar, but the powerband has become very peaky. We never used to go above 1800 rpm when doing field work because it had so much low end torque. Now it seems we have to keep it above 1800 alot because the low end grunt seems lessened. The high end seems to be uneffected though. We have left it alone for the last 2 years because we figured it still ran. After driving the 806 though, it makes me consider trying to fix it. After the piece fell off, the dealer who put the new clutch in screwed it back in and claimed that they reset it. Later, a different mechanic came and said that the pump is junk after that falls out and that he couldn't believe it still ran at all. If it requires replacing the pump, I think I will just let it keep going. That said, anyway to just reset(not rebuild!!) that thing myself? Any ideas or opinions would be appreciated.
