JumperAndSon Posted December 19, 2012 Author Share Posted December 19, 2012 You could just go staight to "boat anchor" and save time. As for the oil, it likely already leaked out. Another option is a lawn ornament. On a serious note, if the injector racks are free, then the linkage is stuck. Try spraying Blaster on all the moving parts and let them soak for a few days.I diconnected the rack from the linkage to the governer and it's definately the rack thats stuck. But what's confusing me is that it wiggles a little bit but it's still stuck. But the next time I get a chance, I'll try lubing it up and tapping on it a little more and see if that works.Ben Quote Link to comment https://www.bigmacktrucks.com/topic/28847-i-need-the-cure-for-my-detroit/page/2/#findComment-151967 Share on other sites More sharing options...
JumperAndSon Posted December 19, 2012 Author Share Posted December 19, 2012 Ben... hold off on the C4..!!!!do you have the later Injector Control Tubes with the individual spring-loaded rack levers???the older rigid tube/lever jammed all injectors if one stuck, newer type elimanted this issue, though you still have to deal with the injector that is stuck..generally, if the newer individual spring tubes are installed the air intake flap can be deleted...if you have the DD V71 bible.. it is chapter 2.9 of the service manualBC MackI would like to get a service manual for it, that's on my christmas wish list. And they are the old style where if one is stuck, they're all held up.Ben Quote Link to comment https://www.bigmacktrucks.com/topic/28847-i-need-the-cure-for-my-detroit/page/2/#findComment-151968 Share on other sites More sharing options...

BC Mack Posted December 20, 2012 Share Posted December 20, 2012 Bencheck the photoif this looks like yours... it is the old styleto help determine which injector is stuck, remove the four bolts holding the two end brackets, lift out the complete tube. examine the control rack of each injector, it should move in-out with some leverage applied.the stuck one will be obvious... 'careful' tapping can release the jammed part but they are a device of fine machining tolerances so don't get brutal... unless you really "want" to play with the C4..!!don't disturb the screws on the lever where it is mounted on the tube.injector removal is straightforward, needs some dismantling of the rocker arms, fuel lines and a heel bar... get a guy who has done it before if you are unsure.service manuals are on ebay from time to time, there are 15 chapters in a complete book, some are sold in two parts, 1-3 & 4-15easy engine to repair as every owner knows, 'cos you're always fixing them..!!!BC Mack Quote Link to comment https://www.bigmacktrucks.com/topic/28847-i-need-the-cure-for-my-detroit/page/2/#findComment-152193 Share on other sites More sharing options...
30yearoldjunk Posted December 20, 2012 Share Posted December 20, 2012 Ben, you and I know Green Leakers deserve more respect than is shown on this forum. If you subtracted out all the work the Screamin' Jimmies accomplished in the oilfield, there wouldn't be much oilfield left. I was really biased against the old GM's until I spent 2 years on a drilling rig that had a pair of Buzzin' Dozens, and a 453. Over 2 decades since their manufacturing demise, there are still a lot of them deafening the hands, confounding the wise, etc. Quote Link to comment https://www.bigmacktrucks.com/topic/28847-i-need-the-cure-for-my-detroit/page/2/#findComment-152226 Share on other sites More sharing options...

I will try doing as you said to figure out whice one is stuck and then maybe I'll be able to get it loose.
