Reassembly

1.Install the shaft u-cup packings (402*) so the lips face out of the housing (1). Lubricate the packings. See FIG. 13.

2.Assemble the air side plate (104) onto the dia- phragm (403). The wide, radiused side of the plate must face the diaphragm. Apply medium-strength (blue) Loctite® or equivalent to the threads of the diaphragm assembly. Screw the assembly into the shaft (24) hand tight.

3.Grease the length and ends of the diaphragm shaft (24). Determine the orientation of the air valve by checking which side the pilot pins (16) protrude far- thest (see FIG. 14). This side will be supplied with air first. Insert the shaft/diaphragm assembly into this side of the pump. Assemble the fluid cover (101) and clamp (106) so the arrow (A) on the cover faces the same direction as the air valve (B). Securely tighten the clamp.

4.Assemble the other diaphragm assembly to the shaft as explained in step 2. This diaphragm will be lifted off the air cover at this point.

5.Set the other fluid cover (101) in place on the dia- phragm, so the arrow (A) on the cover faces the same direction as the air valve (B). Supply the pump with low pressure air (less than 7 psi [.05 MPa, 0.5 bar]). The diaphragm will very slowly pull onto the air cover (23). You can support the movement with your hand by gently pushing on the fluid cover (101).

CAUTION

Do not deform the diaphragm manually. The dia- phragm needs uniform pressure to deform properly.

6.Assemble the fluid cover (101) and clamp (106) so the arrow (A) on the cover faces the same direction as the air valve (B). Securely tighten the clamp.

7.Reassemble the ball check valves and manifolds as explained on page 18.
