CAMSHAFT VALVE CLEARANCE

Camshaft valve clearance

INFOID:0000000011279943

• Perform this inspection as follows after removal, installation, or replacement of the camshaft or any valve

parts, or if there are any unusual engine conditions due to changes in valve clearance over time (starting,

idling, and/or noise). 

1. Remove the fender protector side cover (RH). Refer to 

EXT-28, "FENDER PROTECTOR : Exploded

View"

. 

2. Remove the rocker cover. Refer to 

EM-42, "Exploded View"

.

3. Turn crankshaft pulley clockwise when viewed from front to align

TDC identification mark (B) with timing indicator (A).

NOTE:

Do not confuse TDC mark (B) with paint marks (C).

4. At this time, check that the both intake and exhaust cam lobes of

No. 1 cylinder face outside.

• If they do not face outside, turn crankshaft pulley once more.

5. Measure valve clearances with a suitable tool at locations

marked (X) in the table below.

• No.1 cylinder compression TDC.

CAMSHAFT VALVE CLEARANCE

• Use a suitable tool to measure the clearance between valve

lifter and camshaft. 

6. Turn crankshaft one complete revolution (360

°) and align mark on crankshaft pulley with pointer. 

7. Measure valve clearances with a suitable tool at locations

marked (X) in the table below. 

• No.4 cylinder compression TDC.

If out of specifications, make necessary adjustment.

ADJUSTMENT

NOTE:

• Perform adjustment by selecting the valve lifter with the correct head thickness.
1. Remove camshaft. Refer to 

EM-121, "Camshaft"

.

2. Remove the valve lifters at the locations that are outside the standard.
3. Measure the center thickness of the removed valve lifters with a

suitable tool (A).

4. Use the equation below to calculate valve lifter thickness for replacement.

• Valve lifter thickness calculation.

t = t1 + (C1 - C2)

t = Thickness of replacement valve lifter.

t1 = Thickness of removed valve lifter.

C1 = Measured valve clearance.

C2 = Standard valve clearance.

• Thickness of a new valve lifter (B) can be identified by stamp

marks (A) on the reverse side (inside the cylinder).

Stamp mark 324H indicates a thickness of 3.24 mm (0.1276

in)

Available thickness of valve lifter: 26 sizes with a range of

3.00 to 3.50 mm (0.1181 to 0.1378 in), in steps of 0.02 mm

(0.0008 in), when assembled at the factory.

5. Install the selected valve lifter.
6. Install camshaft. Refer to 

EM-69, "Removal and Installation"

.

7. Install timing chain and related parts. Refer to 

EM-49, "Exploded

View"

. 

8. Manually rotate crankshaft pulley a few rotations.
9. Check that valve clearances for cold engine are within specifications by referring to the specified values.

10. Install all removed parts in the reverse order of removal.
11. Warm up the engine, and check for unusual noise and vibration.

INFOID:0000000011279944

CHECKING COMPRESSION PRESSURE

1. Warm up the engine to full operating temperature. 
2. Release the fuel pressure. Refer to 

EC-147, "Work Procedure"

. 

3. Remove the ignition coil and spark plug from each cylinder. Refer to 

EM-41, "Removal and Installation"

and 

EM-19, "Removal and Installation"

.

4. Connect engine tachometer (not required in use of CONSULT).
5. Disconnect the fuel injector harness connector to avoid any residual fuel injection during the measure-

ment.

6. Install the compression tester with the adapter into the spark

plug hole.

• Use compression tester whose end (a) (rubber portion) is smaller

than 20 mm (0.79 in) in diameter. Otherwise, it may be caught by

cylinder head during removal.

7. With the accelerator pedal fully depressed, turn the ignition switch to the “START” position to crank over

the engine. When the gauge pointer stabilizes, read the compression pressure and engine rpm. Perform

these steps to check each cylinder.

Unit: kPa (kg/cm

2

, psi) / rpm

CAUTION:

Always use a fully charged battery to obtain specified engine cranking speed.

• If the engine speed is out of specified rpm range, check the battery. Check engine speed again with a fully

charged battery. 

• If compression pressure is below minimum value, check valve clearances and parts associated with com-

bustion chamber (valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head gasket).

After the checking, measure compression pressure again.

• If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole of

the cylinder to re-check it for compression.

• If the added engine oil improves the compression, the piston rings may be worn or damaged. Check the pis-

ton rings and replace if necessary.

• If the compression pressure remains at low level despite the addition of engine oil, the valves may be mal-

functioning. Check the valves for damage. Replace the valve or valve seat accordingly.
