Valve Clearance: Adjustments

VALVE CLEARANCE ADJUSTMENT [KL]
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.
- RH exhaust side adjustment shim removal: A
- RH intake side adjustment shim removal: B
- LH intake side adjustment shim removal: C
- LH exhaust side adjustment shim removal: D





3. Install the 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 by using the camshaft cap bolt holes.





6. Tighten bolts A to secure the SST (shaft).
7. Position 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 fine screwdriver, pry up the adjustment shim through the notch on the tappet. Remove the shim by using a magnet. If the adjustment shim is not removed easily, install a washer (3 mm (0.12 inch) under the SST (49 T012 003).
12. Select proper adjustment shim.
New adjustment shim = Removed shim thickness + Measured valve clearance - Standard valve clearance (0.28 mm (0.011 inch) (IN), 0.30 mm (0.012 inch) (EX))
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. Verify the valve clearance.
Standard [Engine cold]
IN: 0.245 - 0.315 mm (0.0097 - 0.0124 inch)
EX: 0.265 - 0.335 mm (0.0105 - 0.0131 inch)
