2AZ-FE ENGINE MECHANICAL: CAMSHAFT: INSTALLATION

INSTALLATION

1. INSTALL CAMSHAFT TIMING GEAR ASSEMBLY

(a) Put the camshaft timing gear and camshaft together with the straight pin and key groove misaligned, as shown in the illustration.
(b) Turn the camshaft timing gear as shown in the illustration while pushing it gently against the camshaft. Push further at the position where the pin fits into the groove.
NOTICE: Be sure not to turn the camshaft timing gear to the retard angle side (the right clockwise).

(c) Check that there is no clearance between the gear and camshaft.
(d) Tighten the flange bolt with the camshaft timing gear fixed in place.
Torque: 54 Nm (551 kgf-cm, 40ft-lbf)
(e) Check that the camshaft timing gear can move to the retard angle side (clockwise) and is locked in the most retarded position.
2. INSTALL CAMSHAFT
(a) Apply a light coat of engine oil to the journal portion of the camshaft.

(b) Install the timing chain onto the camshaft timing gear with the paint mark aligned with the timing mark in the camshaft timing gear as shown in the illustration.

(c) Examine the front marks and numbers, and check that the order is as shown in the illustration. Then install the bearing caps into the cylinder head.
(d) Apply a light coat of engine oil to the threads and under the heads of the bearing cap bolts.

(e) Using several steps, uniformly tighten the 10 bearing cap bolts in the sequence shown in the illustration.
No. 1 Bearing cap - Torque: 30 Nm (301 kgf-cm, 22ft-lbf)
No. 3 Bearing cap - Torque: 9.0 Nm (92 kgf-cm, 80in-lbf)
3. INSTALL NO. 2 CAMSHAFT
(a) Apply a light coat of engine oil to the journal portion of the No. 2 camshaft.

(b) Put the No. 2 camshaft on the cylinder head with the paint mark of the chain aligned with the timing mark on the camshaft timing sprocket.

(d) Examine the front marks and numbers, and check that the order is as shown in the illustration. Then install the bearing caps onto the cylinder head.
(e) Apply a light coat of engine oil to the threads and under the heads of the bearing cap bolts.

(f) Using several steps, uniformly tighten the 10 bearing cap bolts in the sequence shown in the illustration.
No. 2 Bearing cap - Torque: 30 Nm (301 kgf-cm, 22ft-lbf)
No. 3 Bearing cap - Torque: 9.0 Nm (92 kgf-cm, 80in-lbf)

(g) While holding the camshaft with a wrench, tighten the camshaft timing sprocket set bolt.
Torque: 54 Nm (551 kgf-cm, 40ft-lbf)

(h) Check that the paint marks on the chain are aligned with the timing marks on the camshaft timing gear and camshaft timing sprocket. Also, check that the crankshaft pulley groove is aligned with the timing mark "0" of the timing chain cover.
