Valve Clearance Adjustment

1. Remove the camshaft cover. Refer to Camshaft Cover Replacement .



2. Rotate the crankshaft pulley in direction of engine rotation, aligning the pulley groove with the 0 point on the cover, in order to set engine to TDC.



3. Measure the valve clearance at positions (1), (2), (6) and (8).
4. Rotate the crankshaft pulley 360 degrees in direction of engine rotation.
5. Measure the valve clearance at positions (3), (4), (5) and (7).
6. If the measured values are not within specifications, replace the valve tappets.

Specifications

•	Inlet Side: 0.075-0.125 mm

•	Exhaust Side: 0.245-0.295 mm




7. Determine the tappet size. Refer to determining replacement tappet size.

7.1.	Remove the old tappet.

7.2.	Measure the old tappet.

7.3.	Perform the following calculation to determine the replacement tappet size:

Specifications

•	Inlet: value of removed tappet + measured clearance - 0.1 mm = new tappet size

•	Exhaust: value of removed tappet + measured clearance - 0.27 mm = new tappet size

Example:

-	Old tappet = 3.20 mm, clearance was 0.30 mm, Intake clearance value is 0.1 mm

-	3.20 mm + 0.30 mm--0.1 mm = 3.40 mm

-	3.40 mm = 96449615 (part number)
