Replace the Diaphragms

Wear gloves when removing or assembling the dia- phragms to reduce the risk of cuts.

Diaphragm Repair Kit 246011 is available. Parts included in the kit are marked, for example (9*). For the best results, replace both diaphragms.

Always replace the ball check seals (29) when- ever the fluid covers are removed. These seals are included in each of the repair kits.

Disassembly

1.Prepare the pump for repair of the cylinder-side dia- phragm.

a.Remove the 6 screws (39) and fluid cover (37) from the housing side of the pump.

b.Press on the exposed diaphragm (9) to fully extend the cylinder-side diaphragm.

c.Replace the housing-side cover and tighten the 6 screws.

The housing-side cover must be reassembled tightly enough to prevent the shaft from turning when the cylinder-side diaphragm is loosened.

2.Repair the cylinder-side diaphragm.

a.Remove the 6 screws (38) and fluid cover (37) from the cylinder side.

b.Remove the ball check seals (29).

c.The exposed diaphragm should be in the fully extended position (protruding out from the cylin- der). If it is not, reassemble the cylinder-side seals and cover and repeat step 1.

Repair

d.Grip the cylinder-side diaphragm firmly and unscrew it from the rod by hand.

e.Install a new diaphragm (9*) firmly, by hand.

3.Prepare the pump for repair of the housing-side dia- phragm.

a.Press on the cylinder-side diaphragm so that it protrudes into the cylinder. This will fully extend the diaphragm on the housing side.

b.Install new ball check seals (29*).

c.Replace the fluid cover and install the 6 screws. Torque the screws to 16 N•m (12 ft-lb).

4.Repair the housing-side diaphragm.

a.Remove the 6 screws and the fluid cover from the housing side.

b.Remove the ball check seals.

c.The exposed diaphragm should be in the fully extended position (protruding out from the cylin- der). If it is not, reassemble the cylinder-side seals and cover and repeat step 3.

d.Grip the housing-side diaphragm firmly and unscrew it from the rod by hand.

e.Install a new diaphragm (9*) firmly, by hand.

f.Install new ball check seals (29*).

g.Replace the fluid cover and install the 6 screws (39*). Torque the screws to 16 N•m (12 ft-lb).

Spare diaphragms should be stored in a cool, dry place and be used within 8 months to prevent diaphragm fail- ure due to material aging.
