lNew adjusting shims have the thickness stamped on the rear
side.
lShims are available in 33 size from 2.10 mm (0.0827 in) to
2.74 mm (0.1079 in), in steps of 0.02 mm (0.0008 in). Refer to
EM-137, "
Available Shims".
10. Fit the selected adjusting shim to valve lifter.

Place the stamped side of adjusting shim to valve lifter.
11. Compress valve spring using the camshaft pliers [SST: KV10115110] and remove the lifter stopper [SST].
12. Rotate crankshaft 2 to 3 turns by hand.
13. Confirm that the valve clearance is within the specification. Refer toEM-66, "
INSPECTION".
14. Install remaining parts in the reverse order of removal.

Removal and Installation of Valve Oil SealEBS01EK7
REMOVAL
1. Turn crankshaft until the cylinder requiring new valve oil seals is at TDC. This will prevent valve from drop-
ping into cylinder.
2. Remove camshafts. Refer toEM-59, "
CAMSHAFT".
3. Remove adjusting shims and valve lifters. Refer toEM-59, "
CAMSHAFT".
lCheck the installation positions, and keep them to avoid being confused.
4. Rotate crankshaft, and set piston whose valve oil seal is to be removed to TDC. This will prevent valve
from dropping into cylinder.
5. Remove valve collet.
lCompress the valve spring with valve spring compressor,
attachment and adapter [SST]. Remove valve collet with a
magnet hand.
CAUTION:
When working, be careful not to damage valve lifter holes.
6. Remove valve spring retainer and valve spring.
7. Remove valve oil seal with the valve oil seal puller [SST].
INSTALLATION
1. Apply new engine oil to valve oil seal joint surface and seal lip.
2. Using the valve oil seal drift [SST], install valve oil seals referring
to the dimension shown in the figure.
3. Install in the reverse order of removal.

may come off if front chain case is tilted.
b. Apply a continuous bead of liquid gasket on both ends of arched
area (locations where rear chain case is adjoined) as shown in
the figure.
lUse Genuine Liquid Gasket or equivalent.
c. Install front chain case.
lWhen installing, align dowel pin on oil pump housing with the pin hole.
lInstall No. 6, 10 and 11 bolts with the rubber washer to front chain case.
d. Tighten fixing bolts in numerical order shown in the figure.
e. After tightening all the bolts, re-tighten in the same order.
6. Hereafter, install in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
lBefore starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer toMA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".
lUse procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.
lRun engine to check for unusual noise and vibration.
lWarm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.
lBleed air from lines and hoses of applicable lines, such as in cooling system.
lAfter cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

lIf it exceeds the limit (large difference in dimensions), replace it
with a new one.
INSTALLATION
NOTE:
The figure shows the relationship between the mating mark on each timing chain and that on the correspond-
ing sprocket, with the components installed.
CAUTION:
Before starting work, make sure that No. 1 piston is on its compression stroke.
1. Install balancer unit, and tighten mounting bolts in numerical
order as shown in the figure (4WD models).
CAUTION:
If mounting bolts are re-used, check their outer diameter
before installation. Refer toEM-85, "
Balancer Unit Mounting

CAUTION:
In this step, loosen bolts in the reverse order as shown in
the figure.
e. Tighten all bolts.
f. Turn them another 65 degrees clockwise (angle tightening).
CAUTION:
Check tightening angle with an angle wrench [SST] (A) or a protractor. Do not make judgment by
visual check alone.
2. Install rear chain case.
a. Apply a continuous bead of liquid gasket with the tube presser
[SST: WS39930000] on locations shown in the figure.
Use Genuine Liquid Gasket or equivalent.

B, C: Minimize overlapping area of bead, by starting and ending
at areas of bead as shown in the figure. Apply so that the portion
marked * comes at an external location but cannot be viewed
externally after engine assembly.
