0.35 mm 10.0138 In.)
If the thrust clearance is greater than maximum, re±
place the connecting rod assembly. If necessary, re±
place the crankshaft. (d) Retighten the cap nuts 90

BALANCE SHAFT BACKLASH
ADJUSTMENT ON VEHICLE
1. CHECK BACKLASH OF CRANKSHAFT GEAR AND
NO.1 BALANCE SHAFT GEAR
NOTICE: Backlash between the crankshaft gear and No.1
balance shaft gear varies with the rotation of the balance
shaft and the deviation of the crankshaft gear.
Accordingly, it is necessary to measure the backlash at
the 4 points shown in the illustration on the left.
(a) Rotate the crankshaft 2 or 3 times to settle the crank±
shaft gear and No. 1 balance shaft gear.
(b) When No.1 piston is at TDC, check that the punch
marks C shown in the illustration of the balance shafts
are aligned with the grooves of the No. 2 housing.
(d) First turn the crankshaft clockwise, and align the
groove of the No.2 balance shaft housing with the
punch mark A of the No. 1 balance shaft. (c) Check that the punch marks A and B are at the
positions on the No.1 balance shaft indicated in the
illustration.

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±
