ranchhopper Posted October 25, 2015 Share Posted October 25, 2015 Im almost done with the in frame rebuild on the superliner but I cant get the injectors out of the cups on the rear head they are stuck tight and I don't want to ruin them I want to have them tested and rebuilt if needed any suggestions from the pros?

Hans Remmers Posted October 25, 2015 Share Posted October 25, 2015 Good luck. Last 2 valve I did I decided they were getting rebuilt for that reason. Had puller so tight it was twisting out of shape. Soaked in oil for a few days, lightly air hammered around them and heated head some. I also attached a big slide hammer to return line fitting. I think that helped the most but you'll need an extra fitting for top of injector. Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted October 25, 2015 Share Posted October 25, 2015 Some times two hell bars will get them out but I have had to cut the hold down bolts with a torch just below the injector then you can turn them back and forth while spray PB blaster in the injector cups.There is a puller that can be got from mack tools that work good also.Also I have pulled the sleeve with the injector on a few.Always use antiseze when install new ones. 2 Quote glenn akers Link to comment Share on other sites More sharing options...
BGarofalo Posted October 25, 2015 Share Posted October 25, 2015 I had one that after 2 different pullers and various methods of removal it ripped the thread off the top of the injector. Ended up welding a nut to the top and using a puller with an air hammer. Came out with the sleeve. I would say your best bet at salvaging them is remove the studs and use 2 very large prybars while twisting like said above. Quote Link to comment Share on other sites More sharing options...
gearhead204 Posted October 25, 2015 Share Posted October 25, 2015 you could try hot tanking them and see if the hot bath will free them. Quote Link to comment Share on other sites More sharing options...
ranchhopper Posted October 25, 2015 Author Share Posted October 25, 2015 I think I will send the whole head in with the other injectors and let them worry about it seems like more than I want to get into right now. Quote Link to comment Share on other sites More sharing options...
