16. Q. What parts of the Baker gear take the place of the link which is used by the Stephenson or Walschaert motion?
A. The radius bars and reverse yoke.
17. Q. What relation to the main pin is the eccentric crank set to?
A. The eccentric crank always follows the main pin.
18. Q. Should the eccentric rod or eccentric crank break how is the engine put in condition to proceed?
A. The disabled side can have lap and lead travel and a port opening equal to the lead for all cut-offs. First block the bell crank by using a "U" bolt (which should be provided) in the holes placed in the gear frame for this purpose. Throwing reverse lever in mid-gear will help to get bell crank in position to block. Second, take down broken parts. Third, knock out back pin of short reach rod and throw reverse yoke in forward motion against gear frame.
19. Q. What is to be done should a gear connection rod break?
A. Do the same as for a broken eccentric or crank.
20. Q. What is to be done should the upper part of gear connection rod break?
A. If break is close to the middle pin, do the same as for a broken eccentric rod and also tie lower end of gear connection rod to keep it from swinging. If break is near the top and below the jaw, first block the bell crank and wire the connection rod fast to radius bars. If break is through top jaw, do the same as for broken eccentric rod.
