Hello I have a 3406b I'm working on . Changing mains and rods, part numbers on bearings do not match up to my serial #. How do I find correct thrust washer or are all b the same.

Also i change nozzels to 0r3421 to match serial number it had 0r-3423 in it I'm not sure of piston number. Doesn't smoke while running small amount of smoke when you hit accelerator. Pinned timed pump. Truck sat for 10 years.

Also changed bushing orings on pump didn't leak after I did it. But after sitting a month 2 are leaking again. Would that be a bad bushing?

Any info would be appreciated
