Removal
1. Shift the transmission to neutral. Bleed the air reservoirs
and tag and disconnect the nylon tubing at the range
shift valve on the gearshift lever. Tag and disconnect the
tubing at the splitter valve.
NOTE: The range shift valve may be removed from the
gearshift lever without disconnecting the nylon
tubing from the valve, if so desired. This is
recommended if no service is to be performed on
the air shift piping or valves.
2. Loosen the setscrews in the universal joints on the shift
control shaft (at both ends of the shaft) and remove the
shift control shaft.
3. Remove the capscrews securing the master control unit
to the bracket.
4. Loosen the locknuts on the slave control unit mounting
flange studs. Loosen the hex nuts on the mounting
studs, remove all nuts, and lift off the slave control unit.
Installation
1. Route the gear shift up through the cutout in the cab
floor and secure the master unit to the plate with the
capscrews.
2. Install the slave unit onto the studs in the transmission
shift bar cover, ensuring the shift fingers engage
properly with the shift bars inside the transmission.
3. Position the gearshift lever to the neutral (perpendicular)
position and install the shift control shaft, being careful to
maintain the exact position of the slave unit input shaft
and the gearshift lever.
4. After installing the shift control shaft and ensuring the
master and slave unit are synchronized in the exact
neutral position, tighten the setscrews on the shift
control shaft universal joint yokes. There are two
setscrews on each yoke mounted at 90 degrees to each
other. Lockwire these setscrews after tightening.
5. Connect the nylon tubing to the range shift valve if
disconnected.
6. Connect the nylon tubing to the splitter valve.
Lubrication
Lubricate the U-joints with chassis grease. Lubricate the
master unit with chassis grease. Refer to Lubrication on
page 9-1.
SYMPTOM PROBABLE CAUSE SOLUTION
1. Excessive lever
travel or sloppy feel
when shifting.
a. Setscrews loose in control shaft
universal joints or shift fingers.
a. Tighten or replace setscrews.
2. Hard shifting. a. Bent shift bar in transmission.
Damaged cross shaft or bushings in
master or slave unit.
a. Disassemble and repair as necessary
3. Transmission
locked in gear or in
neutral; gearshift
lever moves freely;
no detent feel.
a. Shift control shaft broken, U-joints
loose or disconnected, cross shaft in
slave unit broken, or shift fingers loose.
a. Disassemble and repair as necessary.
4. Gearshift lever
positions do not
correspond to
transmission gear
ranges.
a. Lever in master unit and cross shaft in
slave unit out of phase.
a. Shift transmission to neutral.
Disconnect U-joints at shift control
slave unit; place gear shift lever in
neutral position. Connect U-joints and
tighten setscrews.
