in the m ast jacket. See Section 3B for alignm ent o f
steering column assembly if necessary.
2. To check for p ro p er shift linkage adjustment,
lift the transm ission selector lever towards the steering
wheel. Allow the selector lever to be positioned in drive
(D) by the transmission detent.
N O T E : Do not use indicator pointer as a reference
to position the selector lever. W hen perform ing
linkage adjustm ent, pointer is adjusted last.
3. Release the selector lever. The lever should be
inhibited from e n gaging low ran g e unless the lever is
lifted.
4. Lift the selector lever towards the steering wheel
and allow the lever to be positioned in neutral (N ) by the
transm ission detent.
5. Release the selector lever. The lever should now
be inhibited from engaging reverse range unless the
lever is lifted.
6. A properly adjusted linkage will prevent the
selector from moving beyond both the neutral detent,
and the drive detent unless the lever is lifted to pass over
the mechanical stop in the steering column.
7. If adjustm ent is required, remove screw (A) and
spring washer from swivel (B )-
8. Set transmission lever (C) in N eutral position by
moving lever counter-clockwise to LI detent and then
clockwise three (3) detent positions to Neutral.
9. Position transmission selector lever in Neutral
position as determ ined by the m echanical stop in
steering column assembly.
NOTE: Do not use the indicator pointer as a
reference to position the selector lever. W hen
perform ing linkage adjustm ent, pointer is adjusted
last.
10. Assemble swivel, spring washer and screw to
lever assembly (D) and tighten screw to 20 pound feet.
11. Readjust indicator needle if necessary to agree
with the transm ission detent positions. See Section 3B.
12. Readjust neutral start switch if necessary to
provide the correct relationship to the transmission
detent positions. See Section 8.
13. Check operation (CK Series):
a. W'ith key in " R u n " position and transm ission
in "R everse" be sure that key cannot be removed and
that steering wheel is not locked.
b. With key in "L o ck " position and shift lever
in "P ark " , be sure that key can be removed, that steering
wheel is locked, and that transmission rem ains in " P a r k "
