Removal and InstallationNLEM0024CAUTION:
+When installing sliding parts such as bearings and
pistons, apply engine oil on the sliding surfaces.
+Place removed parts, such as bearings and bearing caps,
in their proper order and direction.
+When installing connecting rod nuts and main bearing cap
bolts, apply new engine oil to threads and seating sur-
faces.
+Do not allow any magnetic materials to contact the signal
plate teeth of flywheel or drive plate, and rear plate.
+Remove the crankshaft position sensor (POS).
+Be careful not to damage sensor edges and single plate
teeth.

DisassemblyNLEM0025PISTON AND CRANKSHAFTNLEM0025S011. Place engine on a work stand.
2. Drain coolant and oil.
3. Remove timing chain.
Refer to EM-23.
SEM877B
4. Remove pistons with connecting rod.
+When disassembling piston and connecting rod, remove snap
ring first. Then heat piston to 60 to 70ÉC (140 to 158ÉF) or use
piston pin press stand at room temperature.
CAUTION:
+When piston rings are not replaced, make sure that piston
rings are mounted in their original positions.
+When replacing piston rings, if there is no punch mark,
install with either side up.

5. Loosen main bearing caps in numerical order as shown in fig-
ure.
6. Remove bearing caps, main bearings and crankshaft.
+Before removing bearing caps, measure crankshaft end
play. Refer to EM-61.
+Bolts should be loosened in two or three steps.
