Disassemble Bearing and Air Gasket

NOTE: Do not remove undamaged bearings. 

1.

Perform the Pressure Relief Procedure, page 12.

2.

Remove the manifolds and disassemble the check 
valves. See Check Valve Repair, page 16.

3.

Remove the fluid covers and diaphragm 
assemblies. See Diaphragm Repair, page 18.

4.

If necessary, disassemble the air valves. See Air 
Valve Repair
, page 21. 
 
NOTE: It is not necessary to remove the air valves if 
only removing the diaphragm shaft bearing (19).

5.

Use an applicable wrench to remove the screws 
(25) holding the air covers (23) to the center 
housing (1).

6.

Remove the air cover gaskets (22). Always replace 
with new gaskets.

7.

Use a bearing puller to remove the diaphragm shaft 
bearings (19), air valve bearings (12) or pilot pin 
bearings (15). Do not remove undamaged bearings.

8.

If the diaphragm shaft bearings (19) were removed, 
reach into the center housing (1) with an o-ring pick 
to hook the u-cup packings (402). Remove u-cup 
packings from the housing. 

9.

Inspect parts for wear or damage. Replace as 
necessary.

Reassembly

1.

If removed, install the shaft u-cup packings (402). 
Ensure the lips face out of the housing (1). 

2.

The bearings (19, 12, and 15) are tapered and can 
only be installed one way. Insert the bearings into 
the center housing (1), tapered end first. Use a 
press or a block and rubber mallet to press-fit the 
bearing. Ensure the bearing is flush with the surface 
of the center housing.

3.

If necessary, reassemble the air valve. See 
Reassemble Air Valve, page 22.

4.

Align the new air cover gasket (22) on the pilot pin 
(16) protruding from the center housing (1). Ensure 
the pin fits through the proper hole (H) in the gasket.

5.

Align the air cover (23) so the pilot pin (16) fits in the 
middle hole (M) of the three small holes near the 
center of the cover. Install the screws (25) and 
hand-tighten. 

6.

Use an applicable wrench to torque the screws (25) 
to 120–150 in-lb (14–17 N•m).

7.

Install the diaphragm assemblies and fluid covers. 
See Reassemble Diaphragms, page 18.

8.

Reassemble the check valves and manifolds. See 
Reassemble Check Valves, page 16.
