2. Insert the piston and connecting rod into the

cylinder with the arrow mark to front of the engine.

Connecting Rod Bearing Assembly Note

1. Install the connecting rod bearing to the

connecting rod and connecting rod caps, as
shown in the figure.

Connecting Rod Cap Assembly Note

Caution

• When assembling the connecting rod caps, align the broken, rough faces of the connecting rods

and connecting rod caps.

1. Tighten the connecting rod bolts in two steps using the SST (49 D032 316).

Tightening torque
(1) 26—32 N·m

{2.7—3.2 kgf·m, 19.2—23.6 ft·lbf}

(2) 80

°—100°

Balancer Unit Assembly Note

1. Confirm by visual inspection that there is no damage to the balancer unit gear and verify that the shaft turns

smoothly.

• If there is any damage or malfunction, replace the balancer unit.

Caution

• Due to the precision interior construction of the balancer unit, it cannot be disassembled.

2. Install the SST as shown in the figure.
3. Turn the crankshaft clockwise the crankshaft is in

the No.1 cylinder TDC position (until the balance
weight is attached to the SST).

4. Install the adjustment shim to the seat face of the

balancer unit.

5. With the balancer unit marks at the exact top

center, assemble the unit to the cylinder block.

6. Set the SST as shown, then measure the gear

backlash using a dial gauge.

Note

• For an accurate measurement of gear

backlash, insert a screwdriver into the
crankshaft No. 1 balance weight area and
set both the rotation and the thrust direction
with the screwdriver, using a prying action,
as shown in the figure.

• If the backlash exceeds the specified range,

remeasure the backlash and, using the
adjustment shim selection table, select the
proper shim, according to the following
procedure.

Caution

• When measuring the backlash, rotate the crankshaft one full rotation and verify that it is within the

specified range at all of the following six positions: 10

°, 30°, 100°, 190°, 210°, 280° ATDC.

Value range

0.005—0.101 mm {0.00019—0.0039 in}

(1) Using master adjustment shim (No.50), assemble the balancer unit to the cylinder block, then measure the

backlash.

(2) Select the proper adjustment shim according to the measured value.
(3) Install the selected adjustment shim to the balancer unit, then assemble the balancer unit to the cylinder

block.
