Removal and Installation
CAUTION:
+When installing bearings, pistons, or other sliding parts,
lubricate contacting surfaces with new engine oil.
+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
surfaces.
+Do not allow any magnetic materials to contact the sig-
nal plate of flywheel.
+Do not remove the signal plate at back.
+Do not place the signal plate side facing under.
+Handle with care so as not to damage the signal plate
[especially four places on protrusions for signal of crank
position sensor (TDC sensor)].
Disassembly
PISTON AND CRANKSHAFT
1. Remove engine. Refer to ªENGINE REMOVALº, EM-3063.
2. Place engine on a work stand.
a. Remove flywheel.
+Hold ring gear with ring gear stopper (KV10105630,
KV10105610). Then, loosen securing bolts with TORX
socket (size: Q8 E20, Commercial Service Tool) and remove
them. As an alternative method, hold the crankshaft pulley
with a pulley holder (SST) to remove the flywheel.
b. Install engine sub-attachment (SST) to rear surface of cylin-
der block.
+To install, align the hole on the sub-attachment with the
knock pin on the cylinder block.
+The engine sub-attachment has five bolts.
c. Install engine attachment (SST).
+The four sets of bolts and nuts are multi-purpose products.

20. Remove engine from engine stand in the reverse order of
assembly.
21. Install flywheel.
+Holding ring gear with ring stopper (SST), tighten securing
bolts with TORX-socket (size: Q8 E20, Commercial Service
Tool).
+Tighten bolts uniformly in a crisscross manner.
REPLACEMENT OF PILOT BUSHING
1. Remove pilot bushing using tool or suitable tool.
2. Install pilot bushing as shown.
