INSTALL A SOLID 1/2-14 NPTF PIPE
PLUG IN THIS LOCATION WHEN USING
PORT SB-2 FOR BALANCE PISTON AND
INLET BEARING SUPPLY.
DO NOT PLUG THIS PASSAGE IF PORT
SB-2 IS NOT PIPED. BLOCKING THIS
PASSAGE WHEN PORT SB-2 IS NOT
PIPED CAN RESULT IN A CATASTROPHIC
FAILURE DUE TO LACK OF OIL SUPPLIED
TO THE BALANCE PISTON AND INLET
BEARINGS.
