shim in addition to those removed originally.

2.For motor replacement, add two (2) shims in addition to shims removed during disassembly.

3.Reassemble pump as described in steps 6 and 7. (See INSTALLATION OF NEW SEAL section.)

IMPORTANT: Insure that casing is snugly in place and check shaft to make sure it is turning freely (use screwdriver slot in the motor to turn shaft). If it turns freely, check to insure that adapter (Ref. No. 7) and casing are fitted metal -to- metal where

they meet on outside. If they are not metal- to-metal, tighten fasteners (Ref. No. 4) and recheck shaft for free turning. Tighten carefully, turning shaft while tightening so that motor bearings are not damaged in the event that too many shims were installed. If shaft seizes before fasteners are completely tight, disassembly pump and remove one (1) shim and repeat reassembly.
