sion.
INSPECTION AFTER REMOVAL
Visual Check of Camshaft

Check the camshaft for one sided wear or scratches.

Replace the camshaft if there are abnormalities.
Camshaft Runout

Prepare V-block on a flat surface and secure camshaft journals
No. 2 and No. 5.

Set the dial indicator vertically on journal No. 3.

Rotate camshaft in one direction by hand, then read needle
movement on dial indicator (total indicator reading).

If it exceeds the limit, replace camshaft.
Camshaft Cam Height

Measure the height of camshaft cam using the micrometer.

If out of the standard, replace camshaft.

Measure the following parts if out of the standard.
–Dimension “A” for camshaft
–Dimension “B” for cylinder head

Refer to the standards above, and then replace camshaft and/or
cylinder head.
Camshaft Sprocket Runout

2. Install sprocket on camshaft. Refer to EM-184, "
INSTALLA-
TION" .
3. Measure camshaft sprocket runout (total indicator reading).

If it exceeds the limit, replace camshaft sprocket.
Valve Lifter and Adjusting Shim
Check if surface of valve lifter and adjusting shim has any wear or
cracks.

If anything above is found, replace valve lifter or adjusting shim. Standard : 6.882 - 6.930 mm (0.2709 - 0.2728 in)

Install so that knock pins are positioned in the directions
shown in the figure.
NOTE:
Though camshaft does not stop at the location as shown in
the figure, for the placement of cam nose, it is generally
accepted that camshaft is placed at the same direction as
shown in the figure.
3. Install camshaft brackets.

Completely remove any foreign material on back surfaces of camshaft brackets and top surface of cyl-
inder head.

Install correctly, identifying brackets by the journal No. and
front mark on top surface.
4. Tighten bolts in the order shown in the figure according to the
following procedure:
a. Tighten all bolts.

Make sure camshaft thrusting parts (on rear side) securely fit
in their mating parts on the cylinder head.
b. Tighten all bolts.
c. Tighten all bolts.
5. Install camshaft sprockets.

Camshaft sprockets are commonly used for right side and left side.

Align camshaft sprocket and knock pin on camshaft, and install.

Holding the hexagonal part of camshaft with a wrench, tighten bolt securing camshaft sprocket.
6. Before installing spill tube after installing secondary timing chain, check and adjust valve clearance. Refer
to EM-185, "
Valve Clearance" .
7. Hereafter, install in the reverse order of removal.
8. Before starting engine, bleed air from fuel piping. Refer to FL-18, "
Air Bleeding" .

INSPECTION

When the camshaft or parts in connection with valves are removed or replaced, and a malfunction has
occurred (poor starting, idling, or other malfunction) due to the misadjustment of the valve clearance,
inspect as follows.

Inspect and adjust when the engine is cool (at normal temperature).

9. Select the new adjusting shim from the following methods.

New adjusting shims have the thickness stamped on the rear
side.

Shims 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).
10. Fit the selected adjusting shim to valve lifter.
CAUTION:
Place the stamped side of adjusting shim to valve lifter.
11. Compress valve spring using the camshaft pliers (special service tool: KV10115110) and remove the lifter
stopper (special service tool).
12. Rotate crankshaft 2 to 3 turns by hand.
13. Confirm that the valve clearance is within the specification. Refer to EM-185, "
INSPECTION" .
14. Install remaining parts in the reverse order of removal. Refer to EM-184, "
INSTALLATION" .
15. Warm up the engine, and check for unusual noise and vibration.Calculation method of the adjusting shim thickness:
R = Thickness of removed shim
N = Thickness of new shim
M = Measured valve clearance
Intake
N = R + [M - 0.28 mm (0.0010 in)]
Exhaust
N = R + [M - 0.30 mm (0.0118 in)]
