Repair procedures

Removal

1. Remove the cylinder head cover.

2. Set No.1 cylinder to TDC/compression.
A. Turn the crankshaft pulley and align its groove with the timing mark "T" of the lower timing chain cover.




B. Check that the mark(A) of the CVVT sprockets are in straight line on the cylinder head surface as shown in the illustration.
If not, turn the crankshaft one revolution (360°)




3. Remove the service hole bolt(A) of the timing chain cover.




4. Insert the SST(A) (09240-2G000) in the service hole of the timing chain cover and release the ratchet.




5. Remove the camshaft.
(1) Remove the front camshaft bearing cap (A) with the upper bearing (B).




(2) Remove the camshaft bearing cap (A) in the sequence shown.




(3) Remove the camshafts (A).




6. Disconnect the intake CVVT assembly(A) and exhaust CVVT assembly(B) from camshaft(C).





NOTE:
When removing the CVVT assembly bolt, prevent the camshaft from rotating by using a wrench at position D.

Installation

1. Install the intake CVVT assembly(A), exhaust CVVT assembly(B) and camshaft(C).

Tightening torque :
53.9 - 63.7 N.m (5.5 - 6.5 kgf.m, 39.7 - 47.0 lb-ft)





NOTE:
When installing the CVVT assembly bolt, fix the camshaft by wrench at position D.

2. Install the camshafts.

NOTE:
Apply a light coat of engine oil on camshaft journals.

(1) Install the exhaust camshaft lower bearing (A).




(2) Install the camshafts (A).




(3) Install the timing chain
Check that the mark(A) of the CVVT sprockets are in straight line on the cylinder head surface as shown in the illustration.




(4) Install the exhaust camshaft upper bearing (A) to the front bearing cap.




3. Install camshaft bearing caps (A) in their proper locations.

M6 : 5.9 N.m (0.6 kgf.m, 4.3 lb-ft)
M8 : 14.7 N.m (1.5 kgf.m, 10.8 lb-ft)
Step 2
M6 : 10.8 - 12.7 N.m (1.1 - 1.3 kgf.m, 8.0 - 9.4 lb-ft)
M8 : 27.5 - 31.4 N.m (2.8 - 3.2 kgf.m, 20.3 - 23.1 lb-ft)




4. Disconnect the SST(A) (09240-2G000).




5. Install the service hole bolt of the timing chain cover.

Tightening torque :
11.7 - 14.7 N.m (1.2 - 1.5 kgf.m, 8.6 - 10.8 lb-ft)
