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.
