●Lift up the cylinder head assembly to avoid interference with
dowel pins located between the block and head, and remove
cylinder head assembly.
CAUTION:
Remove glow plug in advance to avoid damage as the tip
of the glow plug projects from the bottom of the cylinder
head, or, place wood blocks beneath both ends of the cyl-
inder head to keep the cylinder bottom from any contact.
●For glow plug removal, the following shall be noted.
CAUTION:
●To avoid breakage, do not remove glow plug unless necessary.
●Perform continuity test with glow plug installed.
●Keep glow plug from any impact. (Replace if dropped from a height 10 cm (3.94 in) or higher.)
●Do not use air impact wrench.
INSPECTION AFTER REMOVAL
Cylinder Head Bolt Deformation
●Using micrometer, measure the outer diameters d1 and d2 of
bolt thread as shown in the figure.
●If the necking point can be identified, set it as measuring point
d1.
●Calculate the difference between d1 and d2.
●If out of the limit, replace cylinder head bolt.
Cylinder Head-to-block Difference Check
●After installing cylinder head, measure dimension from the front
end surface of cylinder block to that of cylinder head.
●If the difference is out of the range, check fitting of dowel pins
and cylinder head.

Method Using Plastigage
●Remove contamination such as engine oil and dust completely
from crankshaft journals and each bearing surface.
●Cut plastigage slightly shorter than bearing width. Place it in
crankshaft turning direction, avoiding oil holes.
●Install main bearings and bearing cap and tighten to the speci-
fied torque.
CAUTION:
Never rotate crankshaft.
●Remove main bearings and bearing caps, and measure plasti-
gage width using scale on plastigage bag.
CAUTION:
If out of specification, take same action mentioned in “Method by Measurement”.
MAIN BEARING CRUSH HEIGHT
●When the bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude.
●If out of specification, replace main bearings.
MAIN BEARING CAP BOLT DEFORMATION
●Measure the outer diameter of threaded area, d1 and d2, at the
points specified in the figure.
●When the necked point is identified at a point other than where
specified, measure at the point as d2.
●Calculate the difference between d1 and d2.
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 diame-
ter of the bolt thread at the point specified in the figure.
●If a necked point is identified, measure at that point.
●If the measurement exceeds the limit, replace connecting rod
bolts and nuts.
