4 - 2 3 46000 3-SPEED SYNCHROMESH TRANSMISSION TROUBLE DIAGNOSIS
SYMPTOM AND PROBABLE CAUSE
SLIPS OUT OF HIGH GEAR
a. Transmission loose in clutch housing.
b. Control rods interfere with clutch throw-out
lever.
c. Control linkage does not work freely, binds.
d. Does not fully engage.
e. Damaged mainshaft pilot bearing.
f. Clutch gear bearing retainer broken or
loose.
g. Dirt between transmission case and clutch
housing causing misalignment.
h. Damaged or worn crankshaft pilot bushing.
SLIPS OUT OF LOW AND/OR REVERSE
a. First and/or Reverse gears damaged from
operating during partial engagement.
b. Improper mated or worn splines on inside
of first and reverse gear and mainshaft.
c. Improperly adjusted linkage.
PROBABLE REMEDY
a. Tighten mounting bolts.
b. Replace or bend levers and rods to elimi-
nate interference.
c. Adjust and free up shift linkage. Torque
reactions of engine should not cause the
lever on transmission to move. The move-
ment of transmission with respect to body
and frame should be transferred to the
control linkage.
d. Measure length of engagement pattern on
clutching teeth. If less than 7/64", check
for bent levers, shifter shafts, detent cam
plates, control rods and other shift linkage.
Replace or straighten defective parts.
e. Replace pilot bearing.
f. Tighten or replace clutch gear bearing
retainer.
g. Clean mating surface. (Remove burrs etc.)
Check alignment-flywheel housing on engine
block. See paragraph 4-11.
h. Replace crankshaft pilot bushing.
a. Determine cause, for example, worn shift
fork and control lever or rod interference.
Replace worn or bent parts.
b. Replace first, and reverse sliding gear.
Check splines on mainshaft and how to do.
c. Adjust linkage.
