Using a clean cloth, wipe shaft and make certain that it is perfectly clean. NOTE: If removed, slide slinger washer (Ref. No. 2) onto shaft until it is located approximately 1/8" from face of motor bearing hub. 12. Carefully guide motor shaft through seal seat. Secure motor adapter on motor mounting face. 13. Apply a light coating of soapy water to inside rubber portion of seal head and slide onto shaft (with sealing face first) so that rubber portion is just up over shaft shoulder. Do not touch or wipe face of polished part of seal head. 14. Replace any impeller shims which may have been removed in disassembly (see “Shim Adjustment”). 15. Screw impeller back in place, tightening until it is against shaft shoulder. 16. Remount casing seal and pump casing on casing cover. IMPORTANT: Always inspect casing seal for cracks or cuts when unit is disassembled. Replace if damaged. SHIM ADJUSTMENT When installing a replacement impeller (Ref. No. 12) or motor (Ref. No. 1), it may be necessary to adjust number of shims (Ref. No. 11) to insure proper running clearance between impeller and casing (Ref. No. 13). Proceed as follows: NOTE: A proper running clearance is less than 0.010". 1. For impeller replacement, add one 0.010" shim in addition to shims removed originally. 2. For motor replacement, add two 0.010" shims in addition to shims removed during disassembly. 3. Reassemble pump using ”Mechanical Seal Replacement” for reference. IMPORTANT: Insure that casing is in place and check shaft to make sure it is turning freely (use screwdriver slot or two flats at rear of motor to turn shaft). If it turns freely, check to insure that casing cover and casing are fitted “metal to metal” where they meet on outside. If they are not “metal to metal” tighten fasteners (Ref. No. 5) and recheck shaft for free turning. Tighten carefully turning shaft while tightening so that motor bearings are not damaged in event that too many shims were installed. If shaft seizes before fasteners are completely tight, disassemble pump and remove one shim and r...
