3400 injection pmup

ufdaland · Aug 30, 2019

trying to remove the injection pump for repair. I believe I have all lines , controls ,and attaching bolts removed including the three
bolts to the drive plate, and the three mounting bolts . I still cannot separate the pump from the mounting plate . I have tried tapping
with a hammer and tried to rotate the pump body with a punch and hammer all to no avail. it acts like there is still a bolt to be removed
, but where . Any suggestions will be tried , maybe twice.

Sounds like you have all hardware off. Pump should be sealed to timing case with an O ring, but someone could have used a gasket there. Try bumping the pump rear with a small wood block, maybe that will jar it loose. If a gasket with sealer on both sides was used, it will be glued on tight..

my 335 is the same. There is gears on there that you have three bolts holding to the pump. You ll have to take them off from taking the back cover off to get to them
