Lubrication System

To install the switch, follow these steps:

1. Apply pipe sealant with Teflon

(Loctite

No.

59241 or equivalent) to the threads of the switch.

2. Install the switch into the tapped hole in the

breather cover. See Figure 6-8.

3. Torque the switch to 4.5 N·m (40 in. lb.).

Testing

Compressed air, a pressure regulator, pressure gauge

and a continuity tester are required to test the switch.

1. Connect the continuity tester across the blade

terminal and the metal case of the switch. With

0 psi pressure applied to the switch, the tester

should indicate continuity (switch closed).

2. Gradually increase the pressure to the switch. As

the pressure increases through the range of

3.0/5.0 psi the tester should indicate a change to

no continuity (switch open). The switch should

remain open as the pressure is increased to 90 psi

maximum.

3. Gradually decrease the pressure through the

range of 3.0/5.0 psi The tester should indicate a

change to continuity (switch closed) down to

0 psi.

4. Replace the switch if it does not operate as

specified.
