A. Take down main rod, block cross-head, disconnect front end of radius
rod and chain to running board and block the valve to cover ports.
9. Q. With a broken combination lever, union link or cross-head arms,
what would you do?
A. Would disconnect the forward end of the radius rod and secure it to
the running board with a small chain, wire or rope, remove all broken
parts, take off the combination lever, even if not broken, secure the
valve in its central position, loosen cylinder head to provide for
lubrication, leave up main rod and proceed on one side. If valve was
blocked to open rear port slightly, this would provide for lubrication
and the cylinder head need not be loosened.
10. Q. If the radius rod on Walschaert gear is disabled, what should be
done?
A. If broken in front of the link block, take off the broken part by
disconnecting from combination lever, take down eccentric rod, fasten
valve to cover ports and proceed on one side. If broken back of the
link block, block the link block in the desired position and proceed
with both sides.
11. Q. What would you disconnect with a Walschaert gear if a valve yoke
should break?
A. Disconnect the forward end of the radius rod, suspend it from running
board, block the valve, provide for lubricating the piston and proceed.
