Have a John Deere 690 excavator with 6404T engine. Engine had water in it a couple of years from rain through exhaust. Pulled head and pan replaced a couple sleeves and rings and rod bearings.Did not pull fuel pump butdid oil pump need to know how to time oil pump and is it possible to align fuel pump shaft with oil shaft without pulling fuel pump. Hard to find info. Thanks. Johnny
 
If it has the vertical Standyne pump like a 4020, lacking information to the contrary I would say to follow the oil pump gear timing instruction for a 4020, THEN re-install the injection pump.

If you would like, I will post a copy of those instructions.
