A. Take off the disabled parts, block between the top of the link and
link block, having the disabled link blocked down very nearly in full
strokes. For safety, both the top and bottom of the disabled link should
have blocks in its slot; the good link would be held in place by the
reverse lever and should under no consideration be dropped down any
farther than the disabled link was.
85. Q. If the reverse lever or reach rod should break, what should be
done?
A. If either breaks, place an iron bar or suitable piece of material
across the top of both frames, securely fastening it in position, then
fasten the arm of the tumbling shaft to the bar. This will require the
engine to be worked at about half cut-off; handle such part of the train
as the road conditions would permit.
86. Q. What should be done if the piston, piston rod, cross-head, main
rod or crank pin are broken or bent?
A. If a piston should break, would remove broken parts, disconnect valve
stem, clamp valve in central position, and if moving piston would not
damage cylinder, leave main rod up and proceed. If a piston rod,
cross-head, main rod or crank pin are broken or bent, would take down
the main rod, block the valve and cross-head; if piston rod is broken
off at the cross-head, leave main rod up.
