REPAIR AND REPLACEMENT PROCEDURES
(Sheet 1 of 3)
HARDWARE AND THREADED PARTS
Install helical thread inserts when inside threads in castings are stripped, damaged, or not able to withstand desired torque.
Replace capscrews, nuts, studs, washers, spacers, and small common hardware if missing or damaged in any way. Repair minor thread damage by cleaning out
the threads using a tap or die.
Replace all damaged or missing lubrication fittings.
BELTS, WIRING, HOSES AND LINES
Replace belts, hoses, clamps, electrical wiring, electrical switches, circuit breakers, or fuel lines if they fail to meet prescribed standards.
INSTRUMENTS AND GAGES
Replace defective or broken instruments and gages. Replace dials and glass that are so scratched or discolored that it is difficult to read.
BALL AND ROLLER BEARINGS
Anti-friction bearings must be handled in a special way. To keep out dirt and abrasives, cover the bearings as soon as they are removed.
Wash bearings in a non-flammable cleaning solution. Knock out packed lubricant inside by tapping the bearing against a wooden block. Wash bearings again.
Cover bearings with clean material, and set them down to dry.
Then coat bearings with oil. Wrap them in clean paper.
