A. Take down the broken rod and corresponding rod on the other side of
the engine.
93. Q. What can be done if the intermediate side rods were broken on a
consolidation engine having the eccentric on the axle ahead of the main
wheel?
A. In this case the engine must be towed in. It is possible when the
main pin is broken, so that all rods on one side are taken off, to leave
the rods up on the other side and move the engine with her own steam,
but very few roads will allow this, because engineers will be inclined
to leave the main rod up on the disabled side to prevent engine catching
on the center. If main rod is left up on the disabled side, the wheels
will surely slip and wreck the rods on the other side.
94. Q. Should one of the forward tire, main tire, intermediate tire,
back tire, or a trailer tire break, what must be done to bring the
engine up?
A. Would run the wheel of the broken tire on a block in order to raise
the wheel clear of the rail and the box up in the driving box jaws.
Remove the oil cellar and place a block between the driving journal and
pedestal brace to carry the disabled wheel center clear of the rail.
Would also block up on top of the box of the wheel ahead or back as the
case might be, in order to take the weight from the disabled wheel. It
might not be necessary to take off any of the rods, but would run the
engine light to the shop, giving special attention to lubrication of the
disabled wheel and using extra precaution in entering side tracks and
passing over frogs and switches. With the tire of a back driver or
trailer wheel broken, it is usually necessary to swing the rear end of
the engine from the tender to keep the rear end on the track. With an
inside radial journal, box on the trailer axle; for a broken trailer
tire, both trailer wheels must be blocked and swung clear of the rail.
95. Q. What is a good method of raising a wheel when jacks are not
available?
A. By raising the wheel on a hardwood block or iron wedge; a re-railing
frog comes very handy for this purpose.
96. Q. How can it be known when the wedges are set up too tight and the
driving box sticks, and in what manner can they be pulled down?
A. If wedges are set up too tight, it causes the boxes to stick and the
engine to ride rough. Inspection of the engine when moving will locate
the disabled box; usually this gets hot at once and the wedges should be
immediately pulled down. Loosen the jam nuts on the wedge bolts and back
them down; if the wedge is stuck very tight it may be necessary to run
one or more of the wheels over a block; or to loosen the pedestal, brace
bolt and allow the jaws to spread to release the box.
