Rework Procedure
There are (2) seats available. Check the serial number (S/N) of the 8J-8840 Carry Check Valve in order to determine which seat to install.

The difference between the (2) seats is the length. The 340-5474 Seat is longer than the 7J-2372 Seat. The seat depth is deeper on 8J-8840 Carry Check Valves machined prior to S/N 04116 and will use the longer 340-5474 Seat.
