1NZ-FE ENGINE MECHANICAL: CAMSHAFT: INSTALLATION
INSTALLATION
1. INSTALL CAMSHAFT TIMING GEAR ASSEMBLY
NOTE: Install the camshaft timing gear assembly onto the camshaft with the lock pin of the camshaft timing gear assembly released.
(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. When the pin fits the groove, push to ensure a good fit.
NOTE: Do not turn the camshaft timing gear in the retard direction (clockwise).
(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 moves smoothly in the retard direction (clockwise) and is locked in the most retarded position.
2. INSTALL CAMSHAFT
(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 camshaft bearing cap No. 2 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, 9.4 ft-lbf)
NOTE: Tighten each bolt uniformly while keeping the camshaft level.
3. INSTALL NO. 2 CAMSHAFT
(a) Install camshaft No. 2.
(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 camshaft bearing caps No. 1 and No. 2 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.
for bearing cap No. 2 - Torque: 13 Nm (129 kgf-cm, 9.4 ft-lbf)
for bearing cap No. 1 - Torque: 23 Nm (235 kgf-cm, 17 ft-lbf)
NOTE: Tighten each bolt uniformly while keeping the camshaft level.
(f) Using a wrench, hold the hexagonal lobe of camshaft No. 2 and install the flange bolt.
Torque: 64 Nm (653 kgf-cm, 47 ft-lbf)
(g) Remove the bar from the timing chain tensioner.
(h) Turn the crankshaft damper and align its timing notch with the timing mark "0" of the oil pump.
(i) Check that all the pairs of timing marks are aligned.
(j) Apply adhesive to the end 2 or 3 threads of the screw plug.
Adhesive:
Toyota Genuine Adhesive 1324, Three Bond 1324 or Equivalent
(k) Using an 8 mm hexagon wrench, install the screw plug.
Torque: 15 Nm (153 kgf-cm, 11 ft-lbf)
