Posting a quick question before I pull the head and try a hydraulic press to get these suckers out. I have a bobcat 863 with the Duetz engine. Need to replace all four fuel injectors. They are corroded in there. Rust has claimed a hold of them. I removed the hold down bracket which I believe is all I needed to remove. They won't budge. No room to get pliers on them (won't matter as they would be useless) and I've had them soaking in the good stuff (deep creep by seafoam) for two days multiple applications. Have a 20 lb slide hammer with a nut welded to the it and threaded on the injector fuel line connection. I either break the weld or strip the threads of the nut after a hard four or five attempts with the slide hammer. Won't budge at all. No room to fit a socket around it and use another nut/washers to draw it out. I've put a little heat on it but with all the grease, deep creep, and wires close by it makes me nervous. Anybody had luck doing anything else? My last resort is to pull the head and try to press it through with a hydraulic press but at the angle it's at with that small of a hole I'm not real optimistic that will work. Dealer won't quite a price and is 6 weeks out from being able to get it in so that's not really an option. Thanks for any input!!
