4.Disconnect electrical source to motor, following lock-out/tag-out procedure.

5.Remove the six (6) 5/16" fasteners around the circumference of the pump top.

6.Carefully remove the pump top from the pump body.

7.Turn the pump top upside down to expose the diaphragm and rod bolt. (See Fig. 3)

8.Remove the rod bolt.

9.Pull the diaphragm away from the rod.

10.Clean the old silicone adhesive from the top and bottom diaphragm plate and bottom of the rod.

11.Clean the old grease (if any) from the diaphragm sealing groove in the pump body.

To Install the Diaphragm:

 

 

1.

Apply bead of silicone adhesive around the rod bolt hole on both sides of the diaphragm and let cure until the

 

silicone skins over.

 

 

2.

Assemble the diaphragm, upper and lower plates to the rod.

 

3.

Apply silicone grease to the

 

 

 

diaphragm sealing groove in the

pump body.

4.Carefully install the pump top and diaphragm into the pump body. Make certain the diaphragm is properly seated in the groove in the pump body.

5.Tighten the six (6) 5/16" mounting bolts in a criss-cross pattern as shown. (See Fig. 4)

Manual Rotation Method:

1.Remove motor from speed (gear) reducer.

2.Wedge a large flat-bladed screwdriver or pry bar into hollow input shaft keyway of speed reducer and rotate until rod is at bottom dead center. (See Fig. 5)

C. ROD BUSHING INSPECTION AND REPLACEMENT

NOTE: The rod and bearing must be replaced as an assembly because the bearing is pressed into the rod using special equipment.

To Inspect:

1.Follow steps 1 through 11 in “To Remove the Diaphragm” on page 3.

2.Remove the hex nuts from the eccentric pin and slide off the old rod.

3.Inspect the bushing in the rod for wear by measuring the bushing diameter. If worn beyond the service limits, replace the rod and bushing.

New: 0.625" [15.88mm]

Service Limit: 0.630” [16mm]

To Install:

1.Lubricate the bushing and eccentric pin with anti-seize compound.

2.Slide rod onto the eccentric pin. (See Fig. 6)
