WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 10.

1.Relieve the pressure.

2.Remove the manifolds and disassemble the ball check valves as explained on page 16.

3.Remove the fluid covers and diaphragm assem- blies as explained on page 17.

NOTE: If you are removing only the diaphragm shaft bearing (19), skip step 4.

4.Disassemble the air valve as explained on page 14.

5.Using a 10 mm socket wrench, remove the screws (25) holding the air covers (23) to the center housing (1). See Fig. 13.

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

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 you removed the diaphragm shaft bearings (19), reach into the center housing (1) with an

o-ring pick and hook the u-cup packings (402), then pull them out of the housing. Inspect the packings. See Fig. 12.

Reassembly

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

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

3.Reassemble the air valve as explained on page 15.

4.Align the new air cover gasket (22) so the pilot pin (16) protruding from the center housing (1) 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. Apply medium-strength (blue) LoctiteR or equivalent to the threads of screws (25), and install the screws handtight. See Fig. 13. Using a 10 mm socket wrench, torque the screws oppositely and evenly to 130–150 in-lb (15–17 NSm).

6.Install the diaphragm assemblies and fluid covers as explained on page 17.

7.Reassemble the ball check valves and manifolds as explained on page 16.
