If the tray pivot is inline with the flange centers and there are 
underlever assist springs, the springs cause the tray to rotate causing 
damper leakage. One solution is to place a coil spring between the belly 
and the tray. Or, since the pitman is pinned to the tray and trapwork, 
you could put a spring on the trap lever to pull the tray down.
