INSPECT THE SIDE SEAL ASSEMBLY FOR WEAR AND DAMAGE–

b)
Inspect the Check Valve Assembly for damage by measuring the gap between
the mating surface of the Side Block and the bottom edge of the Side Seal
Assembly Insert. A gap measurement of .018” (.46 mm) or less indicates that
the Check Valve Assembly has been crushed due to over tightening and must be
replaced.
