(f) Gently turn the No.1 balance shaft by hand, until
resistance is felt, and measure the backlash.
HINT:
wRotate the No. 1 balance shaft 4 or 5 times to
provide a steady backlash reading.
wTo prevent excessive backlash due to thrust cle±
arance, measure the backlash while pressing on
the rear of the No.1 balance shaft.
Standard backlash (use SST):
0.060 ± 0.100 mm (0.0024 ± 0.0039 In.)
NOTICE: Do not turn the No.1 balance shaft strongly.
(g) Remove the dial gauge and the SST.
(h) Turn the crankshaft clockwise to align the groove of
the No.2 housing with the punch mark B.
(i) Set the dial gauge. (See procedure in step (e))
(j) Measure the backlash. (See procedure in step (f))
Standard backlash ( use SST ):
0.080 ± 0.100 mm (0.0024 ± 0.0039 in.)
(k) Remove the dial gauge. (e) Position the SST and dial indicator as shown in the
illustration.
SST 09224 ± 74010
HINT: Make sure that the stem of the dial indicator is
perpendicular to the SST and that it is placed in the
middle of the 3rd indentation.

(p) Turn the crankshaft clockwise again to align the
groove of the No.2 housing with the punch mark B.
(q) Set the dial gauge. (See procedure in step (e))
(r) Measure the backlash. (See procedure in step (f))
Standard backlash( use SST ):
0.06 ± 0.100 mm (0.0024 ± 0.0039 in.)
(s) Remove the dial gauge.
If even one of the 4 points measured above exceeds
the backlash specification, adjust the backlash with
new spacers.
NOTICE: Use the same size spacers for both the left and
right sides.
HINT:
wVarying the spacer thickness by 0.02 mm
(0.0008 in.) changes the backlash by about 0.042
mrn (0.0017 in.).
wIf the backlash is greater than permitted maxi±
mum, select a thinner shim.
wIf the backlash is less than the specification,
select a thicker shim. (I) Turn the crankshaft clockwise again to align the
groove of the No.2 housing with the punch mark A.
(m) Set the dial gauge. (See procedure in step (e))
(n) Measure the backlash. (See procedure in step (f))
Standard backlash ( use SST ):
0.060 ± 0.100 mm (0.0024 ± 0.0039 in.)
(o) Remove the dial gauge.

3. TORQUE BALANCESHAFT ASSEMBLY
While pulling the center part of the engine balancer in
the direction of the arrow, uniformly tighten the6
bolts in several passes, in the sequence shown.
Torque: 49 N±m (500 kgf±cm, 36 ft±lbf)
4. CHECK AND ADJUST BACKLASH OF CRANK±
SHAFT GEAR AND No.1 BALANCE SHAFT GEAR
(See procedure in step 1) 2. REPLACE THE SPACERS
(a) Uniformly loosen the6 bolts in the sequence shown.
(b) Replace the spacers with new ones.
