A. See that all oil holes are open, cups filled and in good working order, the packing in cellars evenly put in and in contact with the journal.  That waste on top of driving or truck boxes is in proper shape, also that grease cups are filled, and the plugs and jam nuts in good shape, and that the grease cellars contain sufficient grease for the next trip.

4.  Q. How should feeders of all oil cups be adjusted?

A. To feed as small a quantity of oil as possible and regularly to give perfect lubrication.

5.  Q. Why is it bad practice to keep engine oil close to boiler in warm weather?

A. The oil is thinned to such a degree by the heat of the boiler that it runs off as soon as applied, and very often a hot bearing is the result.

6.  Q. In what manner would you care for a hot bearing if discovered on the road?

A. Use as much time as available in cooling the same, making sure that all moving parts are free and carefully lubricated before proceeding.

7.  Q. What kind of oil should be used on hot bearings?

A. Use engine oil unless the temperature of bearing consumes it, when a small quantity of valve oil may be used while the bearing is warm enough to make this oil flow.  The valve oil must be removed as soon as the bearing cools to prevent reheating.

8.  Q. At completion of trip what is necessary?

A. Close all adjustable feeds and examine all lubricated parts by contact with the hand to determine that they are not above running temperature.

9.  Q. How would you determine what boxes to report examined?  Why not report all boxes examined?

A. By placing the hand on driving box, on hub of engine truck wheel and on top of tender truck boxes nearest the brass, and would not report them examined unless the temperature of same was above running heat.  It is not necessary to report all boxes examined, because they do not all give trouble at the same time.  If this report was made, it would appear that a proper inspection had not been made and would result in unnecessary work and waste of material.

10.  Q. Why is it bad practice to disturb the packing on top of driving and engine truck boxes with spout of oil can when oiling engine?

A. This packing is put on top of boxes to assist in keeping dirt and dust out of oil holes, also to aid in gradual lubrication from the top.  If this packing is disturbed it will permit dirt and grit to work into oil holes and on the bearings as well as feed the oil away too rapidly.

11.  Q. How do you adjust grease cups as applied to rods?

A. Screw down plug until you feel a slight resistance from the grease, stop when grease shows between brass and pin; this should be sufficient over the division.

12.  Q. Is it usual for pins to run warm when using grease?

A. Yes; grease does not work properly until it gets warm enough to flow readily over the bearing.
