l NOTE When working with the bearings, do not allow your bare hands to come into contact with the bearings.

Skin deposits will promote corrosion of the bearings.

If you should touch the bearings with your bare skin, thoroughly wash the bearings with alcohol to remove the contaminants.

8.5.2.2 Disassemble the cup bearings and contact rings at the hinge points of the contact blades (refer to Figure 23A in G.E.

4 Instruction Manual GEK-7320).

I 8.5 2 3 Inspect the contact rings for wear.

~

A.

If the contact rings are worn to less than 1/32", replace them.

8.5 2.4 Clean the cup bearings and contact rings with kerosene.

Surveillance Procedure ME-3-327 4.16 kV G.E. Magne-Blast Revision 1 Breaker 8.5.2.5 Immerse the bearings and contact rings in SAE-20 o.- SAE-30 machine oil.

8.5 2.6 Remove the bearings and contact rings from the machine oil and allow the excess oil to drain off.

8.5.2 7 Lubricate the bearings and contact rings with General Electric D50H47 lubricant.

NOTE When reassembling the cup bearings, ensure that the cotter pins are properly seated within the castle nuts on the hinge pin.

This ensures l

proper contact pressure at the hinge.

8.5 2.8 Reassemble the cup bearings and contact rings onto the hinge points of the contact blades.

I 8.5 3 Level 3 Lubrication NOTE When working with the bearings, do not allow your bare hands to come into contact with the bearings.

Skin deposits will promote corrosion of the bearings.

If you should touch the bearings with your bare skin, thoroughly wash the bearings with alcohol to remove the contaminants.

8.5 3 6 Repack the bearings with General Electric D50H15 lubricant, ensuring that all of the metal surfaces are greased.

8.5 3 7 Reassemble the bearings within the breaker mechanism.

8.5 3 8 Wipe the stationary primary contacts with a clean, absorbent cloth, then lubricate with General Electric 'D50H47 lubricant.

8.6 INSULATION TESTS 8.6.1 Meggering NOTE 1 The leads of the megger shall be connected between the breaker case (earth-ground lead) and the primary disconnect bushing (line lead) for the applicable phase when performing a phase-to-ground resistance test.

NOTE 2 When performing phase-to-phase resistance tests, the megger test leads anall be connected between the applicable primary disconnect bushings for the phases being tested.

8.6.1.1 With the breaker in the acLOSED" position, test each phase of

.the breaker to ground and phase-to-phase using the 1000 V scale on the megger.
