a. Hold the middle drive shaft “1”.
b. Install the gear lash measurement tool “2” as
shown.
c. Make sure the dial gauge plunger contacts
the measuring point “a” on the gear lash mea-
surement tool as shown.
d. While gently turning the middle driven shaft
back and forth, measure the middle gear
backlash.
NOTE:
Measure the middle gear backlash at four posi-
tions. Rotate the middle driven shaft 90° each
time and observe the reading on the dial gauge.

ADJUSTING THE MIDDLE GEAR BACKLASH
1. Loosen:
• Middle driven shaft bearing housing bolts
2. Remove:
• Middle driven pinion gear shim(s)
3. Tighten:
• Middle driven shaft bearing housing bolts
CAUTION:
ECA14050
Do not overtighten the middle driven shaft
bearing housing bolts or you may obtain too
little middle gear backlash and damage the
middle gears. If the bolts are overtightened,
loosen them until the crankcase-to-middle-
driven-shaft-bearing-housing clearance is
within specification, as stated below. Then,
repeat all of the previous steps.
NOTE:
• Tighten the middle driven shaft bearing hous-
ing bolts carefully, one thread turn at a time
only. Push in the middle driven shaft bearing
housing and then tighten the bolts to specifica-
tion.
• After tightening the middle driven shaft bearing
housing bolts, loosen them until the clearance
between the crankcase and the housing is ap-
proximately 2 mm (0.08 in), when measured
with a thickness gauge “1”.
4. Hold the middle drive shaft.
5. Turn:
• Middle driven shaft
NOTE:
While carefully tightening the middle driven shaft
bearing housing bolts in stages and in a criss-
cross pattern, turn the middle driven shaft back
and forth until the dial gauge reads 0.10–0.20
mm (0.0039–0.0079 in).
