WARNING:
+Situate vehicle on a flat and solid surface.
+Place chocks at front and back of rear wheels.
+Do not remove engine until exhaust system has com-
pletely cooled off. Otherwise, you may burn yourself
and/or fire may break out in fuel line.
+Be sure to hoist engine and transmission in a safe man-
ner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATA-
LOG.
CAUTION:
+When lifting engine, be careful not to strike adjacent
parts, especially the following: Accelerator wire casing,
brake lines, and brake master cylinder.
+In hoisting the engine, always use engine slingers in a
safe manner.
+For 4WD models, apply sealant between engine and
transmission. Refer to MT section (ªRemoval and Instal-
lationº).
+For tightening torque, refer to M/T and PD sections.
+Before separating engine and transmission, remove the
crankshaft position sensor (TDC sensor) from the
assembly.
+Always pay extra attention not to damage edge of crank-
shaft position sensor (TDC sensor) or ring gear teeth.

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)].

and/or piston set with pin.
CONNECTING ROD BOLT DEFORMATION
+Install nuts to connecting rod bolts. Check that the nut can
be screwed smoothly on bolt threads by hand to the last
thread on the bolt.
+If the nut does not screw in smoothly, measure the outer
diameter of the bolt thread at the point specified in the figure.
+If a necked point is identified, measure at that point.
Standard: 8.90 - 9.00 mm (0.3504 - 0.3543 in) dia.
Limit: 8.75 mm (0. 3445 in) dia.
+If the measurement exceeds the limit, replace connecting rod
bolts and nuts.
FLYWHEEL RUNOUT
Runout (Total indicator reading):
Less than 0.15 mm (0.0059 in)
CAUTION:
+The signal plate is built into the flywheel assembly. Be
careful not to damage the signal plate, especially the
teeth.
+Check the signal plate for deformation or cracks.
+Never place the flywheel assembly with the signal plate
facing down.
+Keep any magnetized objects away from the signal plate.
+Do not allow any magnetic materials to contact the sig-
nal plate teeth.

the cable is installed in an improper position.
Also, with the steering linkage disconnected, the cable
may snap by turning the steering wheel beyond the lim-
ited number of turns.
The spiral cable can be turned up to about 2.5 turns from
the neutral position to both the right and left.
