resealing hydraulic pump on SMTA

My hydraulic pump has been leaking into the distributor and causing #3 plug to misfire. Does anyone know how to do this properly? Someone told me that the shaft of the pump may have a groove worn in it by the old seal. If so what do I do to actually get a positive seal. If there is no groove, then I don't have a problem. Thanks for any help.
 
I had that seal blew also, but a friend had a gauge and we turned it up, to lift the single wing on the woods mower, big mistake,but i was scared i would do something wrong , so hired the new seal installed at a shop,but after we turned the pressure down, no problem, but he said i didnt have a groove in the shaft. I now use the 806 on that mower.
