To obtain a clearance of .025 to .040 of an inch for optimal pump efficiency, measure
the clearance between the impeller and the sealplate. Remove the impeller and
remove an adequate amount of adjusting shims to ensure adequate clearance is
obtained.
Once adequate clearances between the impeller and the sealplate are met, tighten
the impeller with a lathe dog and a block of wood. Insert the impeller bolt then torque
the capscrew to 90-ft. lbs.
NOTE:
If the rotating assembly is left in the pump casing, the clearance may be
measured by cautiously reaching through the fill port with a feeler gauge.
WHEN REUSING AN OLD SEAL, DO NOT ATTEMPT TO SEPARATE THE ROTATING
PORTION OF THE SEAL FROM THE SHAFT SLEEVE. DURING USE THE RUBBER
BELLOWS WILL BOND TO THE SLEEVE AND ATTEMPTING TO SEPARATE THEM
WILL DAMAGE THE BELLOWS.
BEFORE REINSTALLING THE IMPELLER, COMPLETELY CLEAN THE SHAFT AND
IMPELLER THREADS. THE SMALLEST AMOUNT OF DIRT ON THE THREADS COULD
CAUSE THE IMPELLER TO SEIZE ON THE SHAFT, WHICH, IN TURN, MAKES FUTURE
REMOVAL DIFFICULT IF NOT IMPOSSIBLE WITHOUT SHAFT AND IMPELLER
DAMAGE.
Once the rotating assembly is installed in the pump casing, insert the impeller bolt
and torque the capscrew to 90-ft. lbs.
