Reassembly
note

Thoroughly clean all parts to assembled.

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

1.

Assemble the piston and the 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.

Assemble the piston rings.

(1)

Install the oil ring with the coil spring by hand.

(2)

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

(3)

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

(The No.1 ring should be on the opposite side of the No.2 ring and the oil ring should be on the opposite side of the coil spring.) Example)

Example)

3.

Assemble the connecting rod bearings.

(1)

Align the bearing claw with the groove of the connecting rod or connecting rod cap and install the bearings (A) in the connecting rod and connecting rod cap (B).

(2)

Apply a coat of engine oil after assembling the bearings.

4.

Assemble 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)

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.

(2)

Stop after the ring compressor pops free, and check the connecting rod-to-crank journal alignment 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 :

27.5~31.4 N.m (2.8~3.2 kgf.m, 20.3~33.1 lb-ft) + 88°~92°

Using the SST (09221-4A000) (A), tighten the connecting rod cap bolts.

note

Do not reuse the connecting rod cap bolts.

5.

Check the side clearance between piston and connecting rod.

6.

Assemble the other parts in the reverse order of disassembly.
