1.

Assemble the piston and connecting rod.

(1)

Install the snap ring in one side of the piston pin hole.

(2)

Align the piston front mark and the connecting rod front mark.

(3)

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

(4)

Install the snap ring in 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.

note

●

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.

2.

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.

3.

Install the connecting rod bearings.

(1)

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

(2)

Install the bearing (A) in the connecting rod and connecting rod cap (B).

4.

Install the piston and connecting rod assemblies.

note

●

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

●

Install the piston and connecting rod assembly with the front marks facing the front of the engine.

(1)

Remove the connecting rod caps, and slip short sections of rubber hose over the threaded ends of the connecting rod bolts.

(2)

Install the ring compressor, check that the rings are securely in place, then position the piston in the cylinder, and tap it in using the wooden handle of a hammer.

note

Maintain downward force on the ring compressor to prevent the rings from expending before entering the cylinder bore.

(3)

Stop after the ring compressor pops free, and check the connecting rod-to-crank journal alignment before pushing the piston into place.

(4)

Apply engine oil to the bolt threads. Install the rod caps (A) with bearings, and tighten the bolts using the SST (09221-4A000).

Tightening torque :

10.7 ~ 14.7 N.m (1.1 ~ 1.5 kgf.m, 8.0 ~ 10.8 lb-ft) + (88 ~ 92 °)

note

Always use new connecting rod cap bolts. Connecting rod cap bolts are toque-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.

5.

Check the side clearance between piston and connecting rod.

6.

Assemble the other parts in the reverse order of disassembly.
