8.

Remove connecting rod bearings. 

CAUTION:

When removing them, note the installation position. Keep them in the correct.

9.

Remove piston rings from piston. 
• Before removing piston rings, check the piston ring side clearance. Refer to 

EM-459, "Inspection"

.

• Use a piston ring expander (commercial service tool) (A).

CAUTION:

• When removing piston rings, be careful not to damage

the piston.

• Be careful not to damage piston rings by expanding

them excessively.

10. Remove the snap rings (1) using a screwdriver (A), and then

release the piston pin.

11. Remove main bearing cap mounting bolts with the following procedure:

• Measure crankshaft end play before loosening main bearing cap mounting bolts. Refer to 

EM-459,

"Inspection"

.

a.

NOTE:
Always mark the position of each crankshaft bearing shell using
an indelible marker pen, in relation to the crankshaft bearing
number

Remove: 

• the crankshaft bearing cap bolts,
• the crankshaft bearing caps,
• the crankshaft,
• the cranshaft bearing shells.

NOTE:
Always mark the position of each crankshaft bearing shell using an
indelible marker pen, in relation to the crankshaft bearing number
12. Remove the crankshaft thrust washer (1)

13.

Remove piston base cooling jets (1) following this procedure:

CAUTION:

Wear goggles with side protectors for this operation.

a.

• Drill the piston base coolibg jets using a [7 mm (0.3in)] diame-

ter drill bit.

NOTE:
Do not take out the ball from the piston base cooling nozzle, oth-
erwise swarf may enter the lubrification circuit
• Remove the spring tappet (1) and the springs (2) without tak-

ing out the ball (3).

• Remove any swarf present with a brush with non abrasive

bristles and a compressed air nozzle.

b.

• Screw the tool [SST: Mot. 1485-01] (1) into the drilled piston

base cooling jets using a [6 mm (0.2 in)] Allen key, which
slides into the tool [SST: Mot. 1485-01].

c.

• Screw the tool [SST: Emb. 880] (1) on the tool [SST: Mot.

1485-01].

• Remove the piston base cooling jets.
• Fit a blanking plug whenever a piston base cooling jet is

removed.

Assembly

1.

Fully air-blow engine coolant and engine oil passages in the cylinder block, cylinder bore and crankcase
to remove any foreign matter.

CAUTION:

Use a goggles to protect your eye.

2.

Install the new piston base cooling jet following procedure:

a.

Remove the blanking plugs.

b.

Use pressurised air and clean cloths to clean the oil circuit, the cylinders and the joint faces to ensure
there is no swarf present.
