A. Remove the reach rod, block links on lower side to hold them in
running position for proper direction. Unless radius rod lifters can be
uncoupled, leave a little slack in the blocking.
13. Q. How can you tell without opening the steam chest if the valve
covers the port with Stephenson gear? With Walschaert gear?
A. Place the rocker shaft vertical with Stephenson gear. Place the
combination lever vertical with reverse lever in mid gear so the link
block is in the center of Walschaert link.
