Hey guys I posted another thread asking about fuel lines.. Now that I have that worked out thanks to you guys I have delved into deeper waters... Let me start by saying I came up on this ole Bison II almost free.. I traded an old 88 dodge dakota not running in real rough shape for it.. I gave 400 for the truck when I bought it back in 98..
The tractor sat up for a few years and got a water in the fuel tank.. After a day of trying to bleed and purge the air I finally found that I was NOT getting anything out of the injector lines.. I was getting fuel TO but not OUT.. Now I know all about the timing issues that can be ran into with pumps but I could not resist.. I tore into the pump by taking off the access plates.. I can see where the spring loaded pumps one for each injector rides on a cam.. Each pump has a roller that rides upon the cam lobe.. Funny thing I notice right away was there was NO oil in the cam area where all the rolling and actions are applied... I can tell also that when the lifter comes up to push the injector pump it will come up but only push the spring about 1/8 an inch.. Im guessing the spring components are stuck..
Now pardon my lack of knowledge on the subject or component names/terminology .. This is the first run in with diesel and what I've learned is what I've got from the net, books and of course this site..
Questions >>>> are there anything I should be careful or pay extra close attention to as I try to take these spring components/plunger/pumps out or unstick them??
Is the cam supposed to be submerged in oil or is it just greased??
Any ideas on unsticking these "pump" "plungers" that are stuck without damage??
I will post pictures of the assembly when I get back in from working on the tractor..
Thanks guys again for reading and helping!!
