INSPECTION AFTER REMOVAL
Camshaft Runout
●Place a V-block on a surface plate to support No. 2 and No. 5
journals on camshaft.
CAUTION:
Do not support No. 1 journal (camshaft sprocket mounting
side), because its diameter is different from that of the other
4 journals.
●Set a dial gauge vertically onto journal No. 3.
●Rotate the camshaft in one direction by hand and read indication
on the gauge.
●A half of reading value is actual bend.
Camshaft Cam Height
●Measure with a micrometer.
Camshaft Journal Clearance
Outer Diameter of Camshaft Journal
●Measure with a micrometer.
Inner Diameter of Camshaft Bracket
●Tighten camshaft bracket bolts to the specified torque.
●Using an inside micrometer, measure inner diameter of the cam-
shaft bracket.
Calculation of Camshaft Journal Clearance
(Oil clearance) = (Camshaft bracket inner diameter) - (Camshaft journal outer diameter) Standard : 0.02 mm (0.0008 in) or less

Removal and Installation of Valve Oil SealEBS00LQE
REMOVAL
1. Remove camshaft. Refer to EM-32, "CAMSHAFT" .
2. Remove adjusting shim (if so equipped) and valve lifters. Refer
to EM-32, "
CAMSHAFT" .
3. To prevent valve from falling inside cylinder, turn crankshaft until
cylinder with oil seal to be removed is at top dead center.
CAUTION:
When rotating crankshaft, be careful that timing chain is not
caught by front cover.
4. Using valve spring compressor (special service tool), remove valve collet. Then remove valve spring and
valve spring retainer.
5. Remove valve oil seal using valve oil seal puller (special service
tool).
INSTALLATION
1. Apply engine oil on new valve oil seal joint and seal lip.
2. Using valve oil seal drift (special service tool), press fit valve oil
seal to height shown in figure.
3. Perform steps in the reverse order of removal for the following
operations.

2. Using flat-head screwdriver, remove front oil seal.
CAUTION:
Be careful not to damage front timing chain cover and crankshaft.
INSTALLATION
1. Apply engine oil on new front oil seal.
2. Using a suitable drift, press fit until the height of front oil seal is
level with the mounting surface.
●Suitable drift : outer diameter 50 mm (1.97 in), inner diameter
44 mm (1.73 in).
CAUTION:
●Be careful not to damage front cover and crankshaft.
●Press oil seal straight so that it is not curling up or
inclined.
3. Perform steps in the reverse order of removal for the following
operations.
Removal and Installation of Rear Oil SealEBS00LQG
REMOVAL
1. Remove transaxle assembly. Refer to MT-23, "Removal" (RS5F30A), MT-23, "Removal" (RS5F70A) and
AT-411, "Removal" (AUTOMATIC TRANSAXLE).
2. Remove drive plate. Refer to EM-70, "
CYLINDER BLOCK" .
3. Using flat-head screwdriver, remove front oil seal.
CAUTION:
Be careful not to damage mounting surface.
INSTALLATION
1. Using a suitable drift, press rear oil seal to rear oil seal retainer.
●Suitable drift : outer diameter 102 mm (4.02 in), inner diame-
ter 90 mm (3.54 in).
CAUTION:
●Do not touch grease applied on oil seal lip
●Be careful not to damage rear oil seal retainer and crank-
shaft.
●Press in straight to avoid causing any burrs or tilting of
oil seal.

8. Install valve collet.
●Compress valve spring with valve spring compressor (special
service tool). Install valve collet with magnet hand.
●Tap stem edge lightly with plastic hammer after installation to
check its installed condition.
9. Install adjusting shim (if so equipped) and valve lifter.
10. Install engine coolant temperature sensor.
●Apply Genuine Liquid Gasket or equivalent to the thread.
11. Install spark plug tube.
●Press-fit spark plug tube following procedure below.
a. Remove old liquid gasket adhering to cylinder-head mounting
hole.
b. Apply liquid gasket to area within approximately 15 mm (0.59 in)
from edge of spark plug tube press-fit side.
●Use Genuine Liquid Gasket or equivalent.
