Replacing
Components
Disconnect the rectifier as described in “Disconnecting a
Rectifier” in this section. Refer to Figures 5-3 and 8-1 for
component locations and to the diagram on the inside of the
rectifier door.
Notes:
1. Slotted machine screws should be the pan-head type.
2. Slotted machine and hex cap screws should be SAE Grade 2 steel or
equivalent.
3. Socket cap screws should have 100,000 psi minimum tensile strength.
4. Steel flat washers should be furnished under heads of socked cap screws.
5. Ferrous screws and washers should have a corrosion protective finish.
6. Locking means is only required for connections subject to vibration.
Belleville type washers or jam nuts are the preferred means.
7. For less that 1/4 inch thick tapped copper bars, use slotted No. 8, No. 10, or
1/4-inch machine screws to minimize applicable torque. When larger size
screws are required, provide captive-type steel nuts or reduce torques.
8. Torque recommendations are also suitable for all non-ferrous fasteners,
except aluminum.
9. Where application permits, hex cap screws should be used.
