92. Q. In case of broken side rods, what should be done?
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.
