Valve Clearance: Adjustments

1. Remove negative cable at battery.
2. Remove cylinder head cover referring to item Cylinder Head Cover.
3. Remove right side of engine under cover from body.





4. Open air cleaner upper case and shift case and hose position to observe "V" mark on crankshaft pulley.
5. Using 17 mm socket, turn crankshaft pulley clockwise until "V" mark (in white paint) on pulley aligns with "0" (zero) calibrated on timing belt cover.





6. Remove Camshaft Position (CMP) sensor and check camshaft rotor gear position. If it is positioned as shown in figure (i.e. No.1 piston is at (TDC) of compression stroke), check valve lashes at valves (1), (2), (5) and (7).
If it isn't positioned as shown in figure (i.e. it isn't shown in the hole for COP sensor), check valve lashes at valves (3), (4), (6) and (8).

NOTE: When checking valve clearance, insert thickness gauge between camshaft and cam-riding face of rocker arm.








7. If valve lash is out of specification, adjust it to specification by turning adjusting screw after loosening lock nut. After adjustment, tighten lock nut to specified torque while holding adjusting screw stationary, and then make sure again that valve lash is within specification
Special Tool (A): 09917-1 8210

Tightening Torque (a): 12 Nm (9.0 ft. lbs.)





8. After checking and adjusting valve lashes at valves (1), (2), (5) and (7), (or (3), (4), (6) (8)) rotate crankshaft exactly one full turn (360°) and check the same at valves (3), (4), (6) and (8) (or (1), (2), (5) and (7)). Adjust them as necessary.
9. After checking and adjusting all valves, reverse removal procedure for installation.
