IMPORTANT: Always replace both seal seat (Ref. No. 6) and seal head (Ref. No. 7)to insure proper mating of components!Also, impeller seal (Ref. No. 22) (where applicable) should be replaced anytime impeller fastener (Ref. No. 23) has been removed.1.Unthread fasteners (Ref. No. 16) and remove pump casing (Ref. No. 14),casing seal (Ref. No. 5), and flapper valve (Ref. No. 13) from adapter (Ref.No. 4).2.Unthread fasteners (Ref. Nos. 12 and 17) and remove volute (Ref. No. 10)from adapter.3.Remove impeller fastener, impeller seal (where applicable), and impeller (Ref. No. 9).4.Shaft sleeve (Ref. No. 21) (where applicable) and seal head can now be pulled from shaft.IMPORTANT: Care should be taken to insure that the same number of shim washers (Ref. No. 8) are replaced behind impeller as were removed. These shim washers are located directly behindimpeller. These washers as well as impeller key (Ref. No. 24) (where applicable)become loose as impeller is removed.NOTE: Some motors (Ref. No. 20) use an open end 7/16" wrench across flats on rear of motor shaft (remove bearing cap foraccess) to prevent shaft from turning. Othermotor shafts have a screwdriver slot instead of flats.5.Unscrew fasteners (Ref. No. 23). Remove mounting base and handle (Ref. No. 18 &2) (where applicable), and adapter from motor mounting face.6.Push seal seat from back of adapter recess with a screwdriver.7.Clean adapter recess before inserting a new seal seat.The precision lapped faces on mechanical seal are easily damaged.Handle your replacement seal carefully.8.Carefully wipe polished surface of new seal seat with a clean cloth.9.Wet rubber portion of seal seat with a light coating of soapy water.10.Press new seal seat squarely into recessin adapter. If seal seat does not press squarely into cavity, it can be adjusted in place by pushing on it with a piece of pipe. Always use a piece of cardboard between pipe and seal seat to avoid scratching polished surface.11.After seal seat is in place, ensure that it isclean and has not been marred.NOTE: If removed, slide slinger washer (Ref.No. 1) onto shaft until it is located approxi-mately 1/8" from face of motor bearing hub.ing a clean cloth, wipe shaft/shaftsleeve and make certain that it is perfectly clean.13.Secure foot and handle (where applicable)and adapter on motor mounting face.Carefully guide motor shaft through seal seat.14.Replace shaft sleeve and impeller key(where applicable).IMPORTANT: Before installing new shaftsleeve, apply a bead of non-hardening, pliable sealant (such as Permatex® Form-A-Gasket®No. 2) to motor shaft shoulder.15.Wet inside rubber portion of new seal headwith a light coating of soapy water. Slide head onto shaft/shaft sleeve. Seal head and seal seat will meet. Reinstall any shims which have been removed. (See Shim Adjustment).16.Install impeller and reassemble pump.17. A short "run-in" period may be necessaryto provide completely leak-free seal operation.SHIM ADJUSTMENT (365 SERIES ONLY)When installing a replacement impeller (Ref.No. 9) or motor (Ref. No. 20), it may benecessary to adjust number of shims (Ref. No.8) to insure proper running clearance between impeller and volute (Ref. No. 10). Proceed as follows:NOTE: A proper running clearance is less than 0.010" (face of impeller to mating face of volute).1.For impeller replacement, add one (0.010")shim in addition to those removed originally.2.For motor replacement, add two (0.010")shims in addition to those removed during disassembly.3.Reassemble the pump as described in steps 16 and 17 (above).IMPORTANT: Ensure that volute is snugly in place and check shaft to make sure it is turning freely (use 7/16" wrench or screwdriver to turn shaft). If it turns freely, check to ensure that adapter (Ref. No. 4) and volute are fitted metal-to-metal where they meet on outside. If they are not metal-to-metal, tighten fasteners (Ref. No.12 & 17) 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 completelytight, disassemble pump and remove one (0.010") shim and repeat reassembly.4.When proper clearance is obtained,reassemble.3655-95 thru 3657-95 and S pecifications Information and Repair Parts Manual 3790-95 thru379L-95 Please provide following information:-Model number-Serial number (if any)-Part descriptions and number as shown in parts listRepair Parts List3790 (3/4 HP)3791 (1 HP)3792 (1½ HP)3793 (2 HP)379G (3/4 HP)379H (1 HP)3797 (1½ HP)379K (2 HP)379A (1 HP)379B (1½ HP)379C (2 HP)379D (3 HP)3657 (5 HP)Description379F (1 HP)379J (1½ HP)379E (2 HP)379L (3 HP)3655 (5 HP)3656 (7½ HP)Qty.1Slinger washer1534-000-001534-000-001534-000-001534-000-001470-093-001470-093-001 2Handle1515-000-001515-000-001515-000-001515-000-00 -- -- 1 3Fastener******4 4Adapter1608-011-011608-011-011608-011-011608-011-013655-030-093655-030-091 5Casing Seal - Buna N (std)1610-000-001610-000-001610-000-001610-000-002186-000-002186-000-001 - Viton (opt)1610-001-001610-001-001610-001-001610-001-002186-001-002186-001-006 & 7† Shaft seal assy. -Buna N (std)1640-161-961640-161-961640-161-961640-161-961640-163-901640-163-901† - Viton (opt)1640-161-971640-161-971640-161-971640-161-971640-163-911640-163-91 8Impeller Shim pkg. -- -- -- -- 1664-000-901664-000-901 9Impeller379A-011-09379B-011-09379C-011-09379D-011-093655-012-093656-012-091 10Volute379B-150-09379B-150-09379D-150-09379D-150-093655-150-093655-150-091 11Washer******2 12Fastener******2 13Flapper valve -Buna N (std)1609-002-001609-002-001609-002-001609-002-001609-002-001609-002-001 -Viton (opt)1695-011-901695-011-901695-011-901695-011-901695-011-901695-011-90 14Casing2111-001-012111-001-012111-001-012111-001-012112-001-022112-001-021 15Pipe plug******2 16Fastener******4 17Fastener******1 18Foot1506-000-001506-000-001506-000-001506-000-00 -- -- 1 19Fastener******1 20Motor - 1 Phase ODP1626-010-001626-011-001626-012-001626-024-00 -- --1 - 3 Phase ODP1626-014-001626-015-001626-016-001626-025-00 -- --- 1 Phase TEFC1626-069-001626-050-001626-070-001626-071-001626-078-00 --- 3 Phase TEFC1626-077-001626-053-001626-054-001626-072-001626-044-001626-045-00 21Shaft sleeve -- -- -- -- 1472-000-001472-000-001 22Impeller seal -- -- -- -- 1471-020-001471-020-001 23Impeller fastener1784-001-091784-001-001784-001-001784-001-001756-000-001756-000-001 24Impeller key -- -- -- -- 1471-030-001471-030-001 (*)Standard hardware item, available locally(†)Seal head (Ref.
