ineer to insure
successful lubrication?
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 w
