How hard is it to put new input shaft seals in the injection pump. I have diesel in the oil. PK

THE INJECTION PUMP HAS A TRANSFER PUMP ON THE SIDE, UNHOOK THE FUEL LINES, TAKE THE FIVE SMALL SLOTTED MACHINE SCREWS OUT, AND THE TWO 7/16 HEADED BOLTS OUT. PULL THE HOUSING AND GEAR ASSEMBLY OUT, THE GEAR THAT COMES OUT OF THE PUMP HAS A SEAL BEHIND IT. TAKE THE SMALL SNAPRING OFF REMOVE GEAR AND PIN, SHAFT WILL PULL OUT OTHER SIDE. SEAL CAN BE POPPED OUT WITH SCREWDRIVER,IT IS NOT AVAILABLE FROM CASE, I USED A NATIONAL BRAND, DONT HAVE NUMBER WITH ME. GOOD LUCK!

Hey Kelly: There is another place the fuel leaks in. It's an "O" Ring or seal. Very simple fix. Ed Axthelm explained it to me, but I forgot. Maybe worth a shot.
