FJ Cruiser 2WD V6-4.0L (1GR-FE) (2008)
(a) Align the knock pin hole in the camshaft timing gear with the knock pin of the No. 4 camshaft, and insert the No. 4 camshaft into the camshaft
timing gear.
(b) Temporarily install the camshaft timing gear set bolt.
(c) Install the 4 bearing caps in the proper locations as shown.
(d) Apply a light coat of engine oil to the threads of the bearing cap bolts.
(e) Using several steps, uniformly install and tighten the 8 bearing cap bolts in the sequence shown in the illustration.
10 mm (0.39 in.) head - Torque: 9.0 Nm (92 kgf-cm, 80 in-lbf)
12 mm (0.47 in.) head - Torque: 24 Nm (245 kgf-cm, 18 ft-lbf)
(f) Hold the hexagonal portion of the No. 4 camshaft with a wrench, and tighten the camshaft timing gear set bolt.
Torque: 100 Nm (1,020 kgf-cm, 74 ft-lbf)
(g) Remove the pin from the No. 3 chain tensioner.
(h) Release the chain tension between the camshaft timing gear (bank 1) and crankshaft timing gear by turning the crankshaft pulley clockwise
slightly.
4. INSTALL CAMSHAFT
NOTE: Keep the camshaft level while it is being removed. The camshaft thrust clearance is very small and failing to keep it level could crack
or damage the cylinder head journal surface, which receives the thrust force. This could subsequently lead the camshaft to seize or break.
Perform the following steps to avoid such problems.
(a) Align the yellow mark link with the timing mark (1 dot mark) of the camshaft timing gear as shown in the illustration.
(b) Apply new engine oil to the thrust portion and journal of the camshafts.
