The fuel injection pump would leak mild to moderate for a while at the throttle assembly area for a while but recently starting leaking very bad to the point where I need to do some kind of quick fix because I don't want to pull the pump and replace it something just enough to slow it down. As the dozer really only gets used a few times a year. Any help will be greatly appreciated and I will post some pictures as soon as I can. I came across something describing a O-ring fix but I'm not exactly sure how to do it on my particular injection pump. Thanks.

Quick field fix , if there is a flat area behind the arm and on the body of the pump use a leather washer . Diesel will swell the leather making it tighter , needs to be tight on the shaft as well

Hmm ok I appreciate the responses will try the leather washer, does anyone know or have an idea where I can acquire a repair Manual for a Case 450B Dozer. I'm also unsure where to find the exact year of manufacture. Thanks again!
