As a further check, latch the selector lever in the No. 2
position (upper notch) which should provide an engage-
ment of approximately 1/16" with the No.2 margin stop
and a clearance of approximately 1/64" with the No. 1
margin stop. Also latch the selector lever in the No. 1 posi-
tion (lower notch) and see that the engagement of the
margin lever with the No. 1 margin stop is approximately
1/16".
12. THE LINK IN THE NO. 2 TRANSFER UVER is placed
in the second hole from the front end and extends upward
to the second hole from the end of the No.2 key lever.
Adjust the link so that the clearance between the selector
lever and the upper notch in the selector latCh is .010" to
.015" when the No.2 key lever is fully depressed. Check
that the overthrow stop does not choke off the No. 2 key
lever through the selector lever; form the stop if necessary.
Be sure that the overthrow engages the selector lever with-
out interference while the No. 2 selection is being made
and is held in position by the selector lever after the latch
engages (Figure 6). The stop must not interfere with the
selector lever when the No. 1 selection is taking place.

13. THE LINK IN THE NO. 1 TRANSFER LEVER is placed
in the fourth hole from the end and connected to the beck
end of the No.1 key lever (Figure 6). Adjust the link so
that the clearance between the selector lever and the low-
er notch in the selector latch is .010" to .015" when the
No. 1 key lever is fully depressed (Figure 7). After the
above two adjustments have been made the cam release
links should be rechecked.
