Middle driven pinion gear bearing
housing bolt
33 Nm (3.3 m·kgf, 24 ft·lbf)
ECA23P1047
NOTICE
Do not overtighten the middle driven pinion
gear bearing housing bolts or you may ob-
tain too little middle gear backlash and dam-
age the middle gears. If the bolts are
overtightened, loosen them until the crank-
case-to-middle-driven-pinion gear-bearing-
housing clearance is within specification, as
stated below. Then, repeat all of the previous
steps.
TIP
• Tighten the middle driven pinion gear bearing
housing bolts carefully, one thread turn at a
time only. Push in the middle driven pinion gear
bearing housing and then tighten the bolts to
specification.
• Clearance between the crankcase and the
middle driven pinion gear bearing housing
should be approximately 2 mm (0.08 in), when
measured with a thickness gauge "1".

4. Hold the middle drive pinion gear.
5. Turn:
• Universal joint yoke
TIP
While carefully tightening the middle driven pin-
ion gear bearing housing bolts in stages and in a
crisscross pattern, turn the universal joint yoke
back and forth until the dial gauge reads 0.045–
0.090 mm (0.002–0.004 in).
6. Measure:
• Crankcase-to-middle-driven-pinion gear-
bearing-housing clearance
(with a thickness gauge)
7. Select:
• Middle driven pinion gear shim(s) "1"

a. Shims are only available in 0.05 mm incre-
ments, therefore round off to the hundredth's
digit of the calculated thickness and select
the appropriate shim(s) with the following
chart.
b. For example, the clearance between the
crankcase and the middle driven pinion gear
bearing housing is 0.46 mm. Therefore, the
chart instructs you to round off the 6 to 5.
Thus, you should use one 0.15 mm and one
0.30 mm shim.
