note

●

Thoroughly clean all parts to be assembled.

●

Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.

●

Replace all gaskets, O-rings and oil seals with new parts.

Assemble the piston and connecting rod.

(1)

Install the snap ring (A) on one side of the piston pin hole.

(2)

Align the piston front mark (A) and the connecting rod front mark (B).

(3)

Insert the piston pin (A) into the piston pin hole and the small end bore of connecting rod.

(4)

Install the snap ring (B) on the other side after inserting the piston pin.

note

●

Apply a sufficient amount of engine oil to outer surface of the piston, inner surface of piston pin hole and small end bore of the connecting rod before inserting the piston pin.

●

Be careful not to damage and scratch the small end bore, piston pin hole and piston pin when inserting the piston pin.

●

Set the snap ring firmly so that the snap ring can contact with the whole groove of the piston pin hole.

Install the piston rings.

(1)

Install the oil ring expander and 2 side rails by hand.

(2)

Using a piston ring expander, install the 2 compression rings with the code mark facing upward.

(3)

Position the piston rings so that the ring ends are as shown.

Install the connecting rod bearings.

(1)

Align the bearing claw with the groove of the connecting rod and connecting rod cap.

(2)

Install the bearings (A) to the connecting rod and connecting rod cap (B).

Install the piston and connecting rod assemblies.

note

●

Before installing the pistons, apply a coat of engine oil to the ring grooves and cylinder bores.

●

The piston front mark (A) and the connecting rod front mark (B) must face the timing chain side of the engine.

(1)

Install the ring compressor, and check that the bearing is securely in place. Then, position the piston in the cylinder, and tap it in by using the wooden handle of a hammer.

(2)

Once the ring compressor pops free, stop inserting and check the alignment of connecting rod with journal before pushing the piston into place.

(3)

Apply engine oil to the bolt threads. Install the rod caps with bearings, and tighten the bolts.

Tightening torque :

10.8 ~ 14.7 N.m (1.1 ~ 1.5 kgf.m, 8.0 ~ 10.8 lb-ft) + 88 ~ 92°

Using the SST (09221-4A000), tighten the bolts that need to be tightened in the angular tightening method.

note

Always use new connecting rod cap bolts. Connecting rod cap bolts are torque-to-yield bolts designed to be permanently elongated beyond the state of elasticity when torqued, so if the bolts are removed and reused, it may cause the bolts to break or fail to maintain clamping force.
