Valve Clearance: Adjustments

VALVE CLEARANCE ADJUSTMENT [KJ]
Perform this same procedure for all camshafts requiring valve clearance adjustment.





1. Turn the crankshaft clockwise so that the cams on the camshaft requiring valve clearance adjustment points straight up.





2. Remove the camshaft cap bolts as necessary.
A: For Right-Hand exhaust side adjustment shim removal
B: For Right-Hand intake side adjustment shim removal
C: For Left-Hand intake side adjustment shim removal
D: For Left-Hand exhaust side adjustment shim removal





3. Install the Special Service Tools (SSTs) as shown.
Tightening torque: 11.3 - 14.2 Nm (115 - 145 kgf.cm, 100 - 125 inch lbs.)





4. Align the marks on the SSTs (shaft and shaft clamp).
5. Face the (SST) (body) toward the center of the cylinder head, and mount it on the camshaft using the camshaft cap bolt holes.





6. Tighten bolts A to secure the SST (shaft).
7. Face the notch of the tappet so that a small screwdriver can be inserted.
8. Set the SST on the tappet by its notch,





9. Tighten bolt B to secure the SST (body).
10. Tighten bolt C, and press down the tappet.





11. Using a thin screwdriver, pry up the adjustment shim through the notch on the tappet. Remove the shim by using a magnet.
12. Select proper adjustment shim.

New adjustment shim = Removed shim thickness + Measured valve clearance - Standard valve clearance (0.30 mm (0.012 inch))

13. Push the selected shim into the tappet.





14. Loosen bolt C to allow the tappet to move up.
15. Loosen bolt B and remove the SST (body).
16. Remove the SSTs and tighten the camshaft cap bolts.
Tightening torque: 11.3 - 14.2 Nm (115 - 145 kgf.cm, 100 - 125 inch lbs.)





17. Check the valve clearance.
Standard [Engine cold]:
IN: 0.27 - 0.33 mm (0.011 - 0.012 inch)
EX: 0.27 - 0.33 mm (0.011 - 0.012 inch)
