Removal and InstallationEBS01E6B
REMOVAL
1. Drain engine coolant. Refer toCO-7, "Changing Engine Coolant".
2. Remove the following:
lRocker cover (Refer toEM-56, "ROCKER COVER".)
lSpill tube and fuel injector (Refer toEM-44, "INJECTION TUBE AND FUEL INJECTOR".)
lIntake manifold (Refer toEM-20, "INTAKE MANIFOLD".)
lTurbocharger (Refer toEM-28, "TURBO CHARGER".)
lExhaust manifold (Refer toEM-34, "EXHAUST MANIFOLD".)
lSecondary timing chain (Refer toEM-73, "SECONDARY TIMING CHAIN".)
lCamshaft (Refer toEM-59, "CAMSHAFT".)
3. Remove cylinder head assembly.
lRemove cylinder head bolts in the reverse order as shown in
the figure with the cylinder head bolt wrench (commercial ser-
vice tool).
lLift up cylinder head assembly to avoid interference with
dowel pins located between the cylinder block and cylinder
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 cylinder
head, or, place wood blocks beneath both ends of cylin-
der head to keep the cylinder bottom from any contact.
lFor glow plug removal, the following shall be noted.
CAUTION:
lTo avoid breakage, do not remove glow plug unless necessary.
lPerform continuity test with glow plug installed.
lKeep glow plug from any impact. [Replace if dropped from a height 10 cm (3.94 in) or higher.]
lDo not use air impact wrench.
INSPECTION AFTER REMOVAL
Cylinder Head Bolt Deformation
lUsing micrometer, measure the outer diameters d1 and d2 of
bolt thread as shown in the figure.
lIf the necking point can be identified, set it as measuring point
d1.
lCalculate the difference between d1 and d2.
lIf it exceeds the limit, replace cylinder head bolt.
Cylinder Head Distortion
1. Wipe off oil and remove water scale (like deposit), gasket, sealer, carbon, etc. with scraper.
CAUTION:
Use utmost care not to allow gasket debris to enter passages for oil or water.
1. Cylinder head bolt 2. Cylinder head assembly 3. Gasket
4. Dowel pin 5. Cylinder block
