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.

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

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..

Today's Featured Article - Two-Brush Generators - by Chris Pratt. Whether for product liability or because the aftermarket parts and labor business is lucrative, this concept is disturbingly prevalent. Fortunately when you step into your shop and make that jump 50 years back in time to work with your old tractor, this concept goes out the window. Even so, when it comes to the charging system, people quickly revert to this idea and start replacing the major components one at a time until it works. The reason you don't find any decals in your replacement set wit ... [Read Article]
