important information.
NOTE: Apply lithium-based grease whenever instructed
to grease. Order Graco PN 111920.
1. Clean all parts and inspect for wear or damage.
Replace parts as needed.
2. Grease and install the diaphragm shaft u-cup pack-
ings (101*) so the lips face out of the housing.
3. If removed, insert the new bearings (109*) into the
center housing. Use a press or a block and rubber
mallet to press-fit the bearing so it is flush with the
surface of the center housing.
4. Assemble air covers, if removed:
a. Put one air cover on the bench. Install the align-
ment pins (112*) and a new gasket (107*).
b. Carefully place the center section on the air
cover.
c. Install second set of alignment pins (112*) and
gasket (107*) in the center section. Lower the
second air cover onto the center housing.
d. Aluminum Centers: Apply medium-strength
(blue) thread locker on the bolts (103). Install
two bolts and torque to 30-40 ft-lb (41-54 N•m).
Turn the pump over on the bench and install
and torque the other two bolts.
Polypropylene Centers: Apply
medium-strength (blue) thread locker on the
bolts (103) and install a washer (119) on each
bolt. Turn the assembly on its side. The align-
ment pins will help hold it together. Slide one
bolt (103) through from one air cover to the
other. Install a washer (119) and nut (118),
hand tight. Repeat for the other three bolts, then
torque to 25-35 ft-lb (34-47 N•m).
5. Grease and install the pilot valves (110*). Torque to
20-25 in.-lb (2.3-2.8 N•m). Do not over-torque.
NOTICE
Unwanted pressurized air due to worn seals can
lead to reduced diaphragm life.
