I always get this shit out of time when I mess with it! "Special " pullers and all sounds like the f-350 yoke which I STILL cant get off!
I have NO idea how to get injectors out either,--more "special" pullers I would assume! --- The only injectors I ever took out was on the 371 Detroit in the Oliver super 99 gm tractor that I had at one time. Detroit is simple.
