Removal and InstallationNLEM0071CAUTION:
+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 signal
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)].
DisassemblyNLEM0072PISTON AND CRANKSHAFTNLEM0072S011. Remove engine. Refer to ªENGINE ASSEMBLYº, ªRemoval
and Installationº, EM-218.
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.
JEM192G
b. Install engine sub-attachment (SST) to rear surface of cylinder
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.

16. Install rear oil seal retainer.
+Apply a continuous bead of specified liquid gasket (Refer to
EM-158, ªLiquid Gasket Application Procedureº.) on locations
shown in the figure.
JEM234G
17. Install pilot bushing.
+Force fit with the drift [approx. 19 mm (0.75 in) dia.].
SEM513G
18. Install fuel injection pump bracket.
+Install insulator according to the shape of the block, and secure
by placing the bracket against the insulator. (Not installed on
some models)
+Align the bracket with the dowel pins on the block to install.
+The two bolts used for dowel pins have a longer shanks than
the other two.
+Check the protruding distance of the dowel pin for fuel injec-
tion pump.
Standard: 13.0 - 15.0 mm (0.512 - 0.591 in)
19. Install parts to the engine in the reverse order of disassembly.
+Tighten bolts securing brackets of auxiliary components (A/C
compressor, alternator) to the specified torque.
: 57 - 65 N´m (5.8 - 6.7 kg-m, 42 - 48 ft-lb)
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.
