13.The seal flexible cup and stationary seat should be pressed out of the bracket (35) and the cavity cleaned of all residue. Make sure that the 1/32 inch radius in the seal seat cavity is not damaged during disassembly since a sharp edge can eas-

ily cut the flexible cup during reassembly.

MODELS 341A-342A-344A

REASSEMBL Y

Reassembly will generally be in reverse order of disassembly. If disassembly was not complete, use only those steps related to your particular repair program.

1.Press grease seals (51) into frame (57). (344A)

2.Press bearings (53 and 54) onto shaft (55). Snap retainer ring (52) into place. (344A)

E. Support Feet Removed.

14.On Model 344A pumps, remove key (42) from the shaft and remove slingers (47 and 47A).

15.Unscrew capscrews (48) and remove bearing cap (49). Remove “O” ring (oil lubed only) (50) and retainer ring (52).

F. Bracket and Slinger Seal Flexible Cup and Stationary Seat Removed.

16.Slide out shaft (55) and bearings (53 and 54). Since bearings (53 and 54) are press fitted on the shaft, they will have to be pulled or pressed off the shaft. Remove grease seals (51) from frame (57), and bearing cap (49).

17.Remove nameplate (34) and screws (33) only if replacement

is needed.

G. Bearing Cap and Slinger Removed.

H. Shaft Assembly Removed.

3.Slide shaft (55) and bearings (53 and 54) into frame (57) until retainer ring on bearing (54) comes in contact with frame (57). Place “O” ring (oil lubed only) (50) in place. (344A)

4.Fasten bearing cap (49) in position with capscrews (48). Insert grease seals (51A) and position slingers (47 and 47A) on the shaft. (344A)

5.The mechanical seal (27) (see Figure 1) cannot be installed

as an assembly. It is necessary to have the seal seat properly in place in bracket (35) before the balance of parts can be added.

Thoroughly inspect the seal cavity in seal bracket, checking for burrs or nicks which could damage flexible cup of mechanical seal. Apply a film of liquid dishwashing deter- gent (do not use oil or grease) to the flexible cup and seal seat. Insert seat in cup and install in seal bracket, taking care to seat it evenly and squarely.

NOTE

If it is not possible to insert seat with fingers, place the cardboard protecting ring furnished with seal over lapped face of seat and press into place with a piece of tubing having end cut square. Tubing should be slightly larger than the diameter of the shaft. Remove cardboard after seat is firmly seated.

6.On Model 344A pumps, mount bracket (35) by screwing capscrews (32) evenly into frame (57) to assure proper alignment. Turn all capscrews in an even amount. Fasten the bracket and frame to supports (41 and 64) by placing wash- ers (40 and 63) over capscrews (39 and 62) and screwing them into position.

On Model 341A and 342A pumps position bracket (35) on the motor and secure with capscrews (32). Tighten screws evenly to assure proper alignment.
