3. Remove injection tube and injection nozzle assembly. Refer toEC section, ªInjection Tube and Injection Nozzleº in ªBASIC
SERVICE PROCEDUREº.
4. Remove the camshaft.
I Place distinguishing marks on the right and left sides with paint.
I Loosen and remove the installation bolt in reverse order shown
in the figure.
5. Remove the adjusting shim and valve lifter.
I Remove by taking notice of the installation position, and place
outside engine in order to prevent confusion.
Inspection
VISUAL CHECK OF CAMSHAFT
ICheck the camshaft for one sided wear or scratches.
I Replace the camshaft if there are abnormalities.
CAMSHAFT RUNOUT
IPrepare V-block on a flat surface and secure camshaft journals
No. 1 and No. 5.
I Set the dial gauge vertically on journal No. 3.
I Rotate camshaft in one direction by hand, then read needle
movement on dial indicator.
Camshaft bend value is 1/2 of needle movement.
Limit: 0.02 mm (0.0008 in)
HEIGHT OF CAM NOSE
Measure by using a micrometer. Standard:Intake40.468 - 40.508 mm (1.5932 - 1.5948 in)
Exhaust 40.830 - 40.870 mm (1.6075 - 1.6091 in)

VALVE OIL SEAL
1. Remove timing chain. Refer to EM-26, ªTIMING CHAINº.
2. Remove injection nozzle assembly. Refer to ªInjection Tube andInjection Nozzleº in ªBASIC SERVICE PROCEDUREº in EC
section.
3. Remove camshaft. Refer to EM-30, ªCAMSHAFTº.
4. Remove valve lifters and mark order No. on each lifter.
5. Replace valve oil seal according to the following procedure.
When replacing valve oil seal, set the corresponding piston at
TDC. Failure to do so causes the valve to drop into the cylin-
der.
1) Set No. 1 cylinder at TDC.
2) Remove valve springs and valve oil seals for No. 1 and No. 4 cylinders. Valve spring seats should not be removed.
3) Install new valve oil seals for No. 1 and No. 4 cylinders as illustrated. Reinstall valve springs. (pink paint side toward cyl-
inder head)
4) Install valve spring retainers on intake valves and valve rotators on exhaust valves, and remount valve assembly.
5) Set No. 2 cylinder at TDC.
6) Replace valve oil seals for No. 2 and No. 3 cylinders according to steps 2) and 3).
7) Install valve lifters in original positions.
CRANKSHAFT OIL SEAL INSTALLING DIRECTION AND
MANNER
I When installing crankshaft oil seals, be careful to install
them correctly, as shown in the figure.
I Wipe off excess oil after installing oil seal.

sure the maximum clearance value between top surface of spring
and the straightedge Limit: 2.4 mm (0.094 in)
VALVE SPRING FREE LENGTH AND COMPRESSIVE
LOAD
Using valve spring tester, check the following.Free length: 55.43 mm (2.1823 in)
Installation height: 40.8 mm (1.6063 in)
Installation load: 180 - 206 N (18.4 - 21.0 kg, 40.6 -
46.3 lb)
Height at valve open: 32.3 mm (1.2717 in)
Load at valve open: 336 - 372 N (34.3 - 37.9 kg, 75.6 -
83.6 lb)
Assembly
1. Install valve guides, referring to EM-60, ªVALVE SEATREPLACEMENTº.
2. Install valve seats, referring to EM-60, ªVALVE SEAT CON- TACTº.
3. Using valve oil seal drift (SST), install valve oil seals referring to the dimension shown in the figure.
I The figure shows the dimension before valve spring seats are
installed.
4. Install valve spring seats.
5. Install valves.
I Install the valves with bigger openings to intake valve side.
I Note that valve layout here is different from that of conventional
the engine.
