1NZ-FE ENGINE MECHANICAL: CAMSHAFT (for Hatchback): INSTALLATION

1. INSTALL CAMSHAFT TIMING GEAR ASSEMBLY

NOTICE:
Install the camshaft timing gear assembly onto the camshaft with the lock pin of the camshaft timing gear assembly released.

HINT
Perform "Inspection After Repairs" after replacing the camshaft timing gear assembly Programming and Relearning.

(a) Put the camshaft timing gear assembly and camshaft together with the straight pin of the groove.

(b) Turn the camshaft timing gear assembly clockwise while pushing it gently toward the camshaft. Push further at the position where the pin fits into the groove.

NOTICE:
Do not turn the camshaft timing gear to the retard angle (to the right).

(c) Check that there is no clearance between the gear flange and the camshaft.

(d) Tighten the flange bolt with the camshaft timing gear fixed.

Torque : 64 Nm (653 kgf-cm, 47 ft-lbf)

NOTICE:
* Do not lock the camshaft timing gear assembly when tightening the bolt.
* Release the lock pin of the camshaft timing gear assembly first, and tighten the bolt when the lock pin is locked in the most retarded position.
* Tightening the bolts with the lock pin locked could cause breakage of the lock pin.

(e) Check that the camshaft timing gear assembly can move to the retard angle (to the right) and is locked in the most retarded position.

2. INSTALL CAMSHAFT

HINT
Perform "Inspection After Repairs" after replacing the camshaft Programming and Relearning.

(a) Apply a light coat of engine oil to the camshaft and camshaft journals.

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

(c) Examine the front marks and numbers on the No. 2 camshaft bearing cap and check that the sequence is as shown in the illustration. Then uniformly tighten the bolts, in several steps, in the sequence shown in the illustration.





Torque : 13 Nm (129 kgf-cm, 9 ft-lbf)

NOTICE:
Tighten each bolt uniformly while keeping the camshaft level.

3. INSTALL NO. 2 CAMSHAFT

HINT
Perform "Inspection After Repairs" after replacing the camshaft Programming and Relearning.

(a) Install the No. 2 camshaft.

(b) Hold the chain and align the timing mark on the camshaft timing sprocket with the paint mark of the chain.

(c) Align the alignment pin hole in the camshaft timing sprocket with the alignment pin of the camshaft, and install the sprocket onto the camshaft.

(d) Provisionally install the flange bolt.

(e) Examine the front marks and numbers on the No. 1 and No. 2 camshaft bearing caps and check that the order is as shown in the illustration. Then uniformly tighten the bolts, in several steps, in the sequence shown in the illustration.

No. 2 bearing cap - Torque : 13 Nm (129 kgf-cm, 9 ft-lbf)

No. 1 bearing cap - Torque : 23 Nm (235 kgf-cm, 17 ft-lbf)

NOTICE:
Tighten each bolt uniformly while keeping the camshaft level.

(f) Using a union nut wrench 14 mm, hold the hexagonal lobe of the No. 2 camshaft and install the flange bolt.





Torque : 64 Nm (653 kgf-cm, 47 ft-lbf)

HINT
Use the formula to calculate special torque values for situations where a union nut wrench is combined with a torque wrench Service Precautions.

(g) Remove the bar from the timing chain tensioner.

(h) Turn the crankshaft damper and align the timing notch with the timing mark "0" of the oil pump.

(j) Apply adhesive to 2 or 3 threads of the screw plug end.

Adhesive:

Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent

(k) Using an 8 mm (0.31 in.) hexagon wrench, install the screw plug.

Torque : 15 Nm (153 kgf-cm, 11 ft-lbf)
