977L injection pump plungers??

cat on fire

Great sight by the way. Ive picked up a lot of info from here. Thanks for all the help

Went out to start our 977L dozer after 5 years. Yeah I know. Shouldn't have left it sitting for so long. Ran great when parked.

Anyways, I think 4 of the plungers are stuck in the injection pump. finally got it to run long enough to get 2 working. idles on its own. When I crack the other 4 injection lines I just get fuel pouring out. The two working injectors I get timed fuel spray and pressure. Also kills the motor. I dumped the fuel filter and filled with marvels mystery oil. And ran It up to the plungers. This is as far as ive got. Has anyone had any luck on unsticking these things? If I read correctly I can take the side plate off and inspect. Just giving the oil a few days to do its magic I hope and run it some more. And I might have a totally different issue. Any thoughts are most appreciated.
 
I haven't unstuck the plungers on one of those, but I have had luck doing basically the same thing on the pump on my old 3500 Ford industrial.

Beyond that, the best I can offer is, good luck.
 
pull the side plate off the injector pump and spray loose juice on the plungers and start working them gently up and down
make sure the rack slide is free also
 
Ok!!! Thanks for all the suggestions. Got the side cover off. The slide rack, Which is the governor bar, Had 4 sleeves froze to the injection plungers. After soaking them and trying to wrk them I got the torch out and heated them. It looked like the governor slides are aluminum. So heated them several times and finally got all of them unstuck. Took a lot of heat and time. Put all back together and it fired right up. The governor also works like it should now. I also dumped a gallon of tranny fluid in the diesel. Just for a little extra lube. I'll right up a how to next day for google searches.[/img]
