5.
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.
DISASSEMBLY. (Illus. 4-29).
1.
Disassemble the master and slave control units as shown.
2.
Discard all gaskets and seals as they are removed.
3.
Do not remove scraper bushings (23) from slave housing (24) unless replacement of bushings is necessary.
INSPECTION AND REPAIR.
1.
Clean all disassembled parts of the shift control group, using Stoddard Solvent, or similar, cleaning fluid, and
examine all parts carefully for the following.
a. Worn bores or bushings in housings, yokes and fingers.
b. Damaged threads, particularly in all set screw holes.
c. Bent shafts (finger shafts, yoke shafts, and shift control shaft).
d. Cracked or broken fingers, yokes, and housings.
2.
Repair for any of the above conditions is accomplished by replacement of the part found defective.
REASSEMBLY.
1.
Reassemble the master control unit and slave unit. Do not install shift control shaft (19) at this time. Use all new
gaskets and seals during reassembly.
2.
Make certain, during reassembly, that the set screws (39) in the shift fingers (32 and 38) are quite secure before
installation of the slave unit on the transmission.
3.
Movement of the parts must be free, but not sloppy. Proper assembly and adjustment will provide good "feel" of the
shifting pattern for the driver and prevent the possibility of the transmission jumping out of gear.
INSTALLATION.
1.
Position the master control unit against its mounting bracket, and install three capscrews and lockwashers to hold
the unit on the bracket.
NOTE
IT MAY BE NECESSARY TO REMOVE THE KNOB FROM THE GEARSHIFT LEVER WHEN
INSTALLING THE MASTER UNIT ONTO THE MOUNTING BRACKET.
2.
Install the slave unit onto the studs in the transmission shift bar cover, making sure that the shift finger engages
properly with the shift bars inside the transmission.
3.
Position the gearshift lever in 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 making sure that master and slave unit are synchronized in exact neutral
position, tighten the set screws on the shift control shaft universal joint yokes. There are two set screws
4-95
