5. Remove cylinder head assembly.
+Loosen and remove mounting bolts in the reverse order
shown in the figure.
+Lift up the cylinder head assembly to avoid interference with
dowel pins located between the block and head, and remove
cylinder head assembly.
CAUTION:
+Do not drop the O-ring located between the front of cyl-
inder head and the rear of gear case into the engine.
+Remove glow plug in advance to avoid damage as the tip
of the glow plug projects from the bottom of the cylin-
der head, or, place wood blocks beneath both ends of
the cylinder 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 nec-
essary.
+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.
6. Remove idler gear.
CAUTION:
While removing idler gear, keep the rear of idler gear facing
up to prevent idler shaft from falling.
Inspection
CYLINDER HEAD BOLT DEFORMATION
(ELONGATION)
+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 d2.
+Calculate the difference between d1 and d2.
Limit: 0.15 mm (0.0059 in)
IDLER GEAR END PLAY
+Tighten mounting bolts to the specified torque.
+Using feeler gauge, measure the clearance between gear
plate and idler gear.
Standard: 0.07 - 0.14 mm (0.0028 - 0.0055 in)
Limit: 0.2 mm (0.0079 in)
+If the measured value exceeds the limit value, replace idler
gear, shaft, and gear plate.

5)Tighten bolts at the angle of 90 to 95É (target is 95É). (Angle
tightening)
6) Once again, tighten bolts at the angle of 90 to 95É (target is
95É). (Angle tightening)
CAUTION:
Perform the following procedure to check turning angle of
angle tightening, and do not judge by visual check.
ANGLE TIGHTENING PROCEDURE
With protractor
+Make counter marks on the bolt head of cylinder head and
cylinder head surface with paint, and check the turning angle.
With angle wrench (SST)
+Check the turning angle using angle indicator of angle
wrench.
6. Loosen gear case mounting bolts which were tightened in 3)
of procedure 4, retighten them to the specified torque.
7. Install glow plug.
+2 different types (manufacturers) of glow plugs are provided
in parallel. (Refer to the figure for identification.)
+Do not install 2 different types of glow plugs in the engine.
Make sure that the same glow plugs are installed.
+Using reamer, remove the carbon adhering to the installation
hole of glow plug, and install glow plug.

position.
1. Check oil level.
2. Remove oil pressure switch.
3. Install pressure gauge.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.

performed on the following items as shown in the table.
A Ð Driving under dusty conditions
B Ð Driving repeatedly short distances
C Ð Towing a trailer or caravan
D Ð Extensive idling
E Ð Driving in extremely adverse weather condi-
tions or in areas where ambient tempera-
tures are either extremely low or extremely
high
