The illustrated wooden gauge, if made, will
greatly aid in shift linkage adjustment.
1. Put the shift lever in Neutral, install the
block gauge, and remove the clevis pin from
the clevis of each shift rod.
2. Adjust the threaded clevis until the

clevis pin freely enters the holes in the clevis
and the selector levers.
3. Secure the pins and lock the clevis se-
curing nuts.
Remove the gauge block and check the shift
pattern. Minor adjustment of the rods may
be necessary to remove all traces of shifting
roughness.

1. Position the individual selector levers
and the shift lever in Neutral.
2. Construct a block gauge Ya in. thick by
41
/64 in. wide and install it in the shift lever
bracket assembly.
3. Attach the first/second shift rod to the
lever. Hold the lever against the gauge block
and adjust the threaded swivel on the shift
rod until the clevis pin freely enters the clevis
hold and hole in selector lever. Secure the
locking nuts.
4. Repeat the procedure and attach the re
verse rod to the selector lever, and the
bracket lever. Repeat again to adjust the
third/fourth rod.
5. Remove the block gauge, check the pat
tern for correct shifting, and adjust, if neces
sary, to correct minor shifting, and adjust, if
necessary, to correct minor shifting difficul
ties.
6. An alternate clevis pin hole is placed on
each selector lever below the regular pattern
hole. This lower placement of the shift rods
will tighten the pattern and permit shorter
shift lever movement for a faster shift. Bear
in mind, however, that this adjustment will
increase the shifting effort.

1. Place the ignition switch in "lock."
2. Loosen locknuts at swivels on shift rods
and reverse control rod.
