3UZ-FE ENGINE MECHANICAL: CAMSHAFT (for Bank 1): INSTALLATION

INSTALLATION

1. INSTALL CAMSHAFT SUB GEAR

SST: 09960-10010
09962-01000
09963-00500
(e) Align the gear teeth of the driven main gear and sub gear, and tighten the service bolt.
Torque: 5.4 Nm (55 kgf-cm, 48 in-lbf)
2. INSTALL CAMSHAFT TIMING TUBE ASSEMBLY

(a) Insert a new oil seal into the camshaft timing tube until it reaches the stopper.
- Be careful of the installation direction.
- Do not turn over the lip of the oil seal.

(b) Align the timing tube knock pin with the knock pin groove of the drive gear, and temporarily install the drive gear with the 4 bolts.

(c) Using SST and a 5 mm hexagon wrench, uniformly tighten the 4 bolts in several passes in the sequence shown in the illustration.
SST: 09960-10010
09962-01000
09963-00500
Torque: 7.5 Nm (76 kgf-cm, 66 in-lbf)
NOTE:
Be careful not to damage the timing tube.

(d) Mount the hexagon head portion of the camshaft in a vise between aluminum plats.
NOTE:
Be careful not to damage the camshaft.

(e) Align the camshaft knock pin with the knock pin groove of the timing tube, and push the timing tube by hand until it touches the bottom.
(f) Using a 10 mm hexagon wrench, install the bolt.
Torque: 78 Nm (795 kgf-cm, 58 ft-lbf)
(g) Install the seal washer and screw plug.
Torque: 15 Nm (152 kgf-cm, 11 ft-lbf)
3. INSTALL NO. 3 CAMSHAFT AND NO. 4 CAMSHAFT
NOTE:
Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being installed. If the camshaft is not kept level, the portion of the cylinder head receiving the shaft thrust may crack or be damaged, causing the camshaft to seize or break. To avoid this, the following steps should be carried out.

(a) Check that the set key of the crankshaft is at a position 45° counterclockwise from the timing mark (1 dot mark) of the oil pump body.
NOTE:
The crankshaft must be at the correct angle to avoid damage in later steps. If the crankshaft is at the wrong angle and then the camshaft is installed, the piston head and valve head may come in contact and be damaged.

(b) Apply MP grease to the thrust portion of the camshafts.

(d) Apply seal packing to the camshaft housing plug.
(1) Remove the old packing (FIPG) material.
(2) Apply seal packing to the housing plug as shown in the illustration.
Seal packing:
Toyota Genuine Seal Packing Black, Three Bond 1207B or equivalent

(e) Install the camshaft housing plug to the cylinder head as shown in the illustration.
(f) Install the oil control valve filter to the cylinder head.
NOTE:
Be careful of the installation direction.

(g) Apply seal packing to the front bearing cap.
(1) Remove any old packing (FIPG) material.
(2) Apply seal packing to the bearing cap as shown in the illustration.
Seal packing:
Toyota Genuine Seal Packing Black, Three Bond 1207B or equivalent
Seal diameter:
1.5 to 2.0 mm (0.059 to 0.079 in.)
NOTE:
Do not apply seal packing to the front bearing cap grooves.

(h) Install the front bearing cap.
HINT: Installing the front bearing cap will determine the thrust portion of the camshaft.

(i) Push in the camshaft setting oil seal.

(j) Install the other bearing caps in the sequence shown, with the arrow marks facing forward.

(k) Install new seal washers to the bearing cap bolts A and B.
Bolt length:
94 mm (3.70 in.) for A with seal washer
72 mm (2.83 in.) for B with seal washer
(l) Apply a light coat of engine oil to the threads of the bearing cap bolt A and B.
NOTE:
Do not apply engine oil under the heads of the bearing cap bolts A and B.

(m) Apply a light coat of engine oil to the threads and under the heads of the bearing cap bolts C, D and E.
Bolt length:
25 mm (0.98 in.) for C
52 mm (2.05 in.) for D
38 mm (1.50 in.) for E
(n) Install the oil feed pipe and the 22 bearing cap bolts shown in the illustration below.
NOTE:
Install the pipe with the "E[down]" mark facing towards the exhaust side.

(o) Uniformly tighten the 22 bearing cap bolts in several passes in the sequence shown in the illustration.
Torque: 7.5 Nm (76 kgf-cm, 66 in-lbf)
Torque: 16 Nm (163 kgf-cm, 12 ft-lbf)

(p) Remove the service bolt.
4. INSTALL CAMSHAFT TIMING PULLEY SUB-ASSEMBLY LH

(a) Align the camshaft timing tube knock pin with the knock pin groove of the timing pulley.
(b) Attach the timing pulley to the camshaft timing tube. Face the timing pulley's "L" mark forward.
(c) Hold the camshaft with a wrench and install the 4 pulley bolts.
Torque: 7.5 Nm (76 kgf-cm, 66 in-lbf)
5. INSTALL CYLINDER HEAD COVER SUB-ASSEMBLY LH

(a) Remove any old packing (FIPG) material.
(b) Apply seal packing to the cylinder heads as shown in the illustration.
Seal packing:
Toyota Genuine Seal Packing Black, Three Bond 1207B or equivalent
NOTICE:
- Remove any oil from the contact surface.
- Install the oil pan within 5 minutes after applying seal packing.
- Do not start the engine within 2 hours after applying seal packing.

(c) Install the gasket to the cylinder head cover.
(d) Install the seal washer to the bolt.
