A-904 Pump front seal replacement.

Check the converter over real good too. If it's not a billet snout on the converter it may have a hairline crack. I used to work on forklifts and ran into one once that had a cracked snout and it only leaked under a full load. After first replacing the seal and seeing nothing wrong by the naked eye it still leaked so we took it back apart and rigged up a rubber seal on the converter snout and applied air pressure and found the leak down where it was welded together
