  Q: How to install the camshaft timing gear assembly and related components for the camshaft, including timing chain alignment, bearing cap tightening, chain tensioner setup, valve clearance adjustment, cylinder head cover installation, and final inspections on Toyota Matrix?

  A: Start by orienting the camshaft timing gear and camshaft with their straight pin at an angle to the key groove before applying gentle force to the gear while turning it against the camshaft. During installation keep the direction of gear rotation pointed toward advancement (counter-clockwise). Verify that the timing gear and camshaft flange do not have clearance before torquing the flange bolt to 54 Nm (551 kgf-cm, 40 ft-lbf). The assembly should then move to the retarded position and lock in place. The journal portion of the camshaft needs a light coating of oil before installing the timing chain onto the camshaft timing gear with paint marks matching timing marks. Place bearing caps in the cylinder head after verifying their front marks and numbers. Correctly apply engine oil on all bearing cap bolt threads and bolt heads before implementing a distribution of torque force beginning with 30 Nm (301 kgf-cm, 22 ft-lbf) on No. 1 bearing bolt and 9.0 Nm (92 kgf-cm, 80 in-lbf) for No. 3 bearing bolt. First apply engine oil to the journal portion then align the paint mark on the chain with the timing mark on the camshaft timing sprocket and temporarily fasten the camshaft timing sprocket set bolt before installing bearing caps while checking front mark and number order. Before tightening, apply engine oil to the threads and under the heads of the bearing cap bolts. Then uniformly torque the 10 bearing cap bolts with No. 2 bearing at 30 Nm (301 kgf-cm, 22 ft-lbf) and No. 3 bearing at 9.0 Nm (92 kgf-cm, 80 in-lbf), after which tighten the camshaft timing sprocket set bolt to 54 Nm (551 kgf-cm, 40 ft-lbf) while holding the camshaft with a wrench. The chain paint marks need to match the timing marks on the camshaft timing gear and sprocket and the crankshaft pulley groove should align with the timing mark "0" on the timing mark chain cover. The procedure for the No. 1 chain tensioner assembly begins with releasing the ratchet pawl along with pushing the plunger into position and setting the hook onto the pin. Next, install a new gasket and the chain tensioner with two nuts tightened to 9.0 Nm (92 kgf-cm, 80 in-lbf). Proceed by turning the crankshaft counterclockwise to remove the hook and finally check plunger extension by turning the crankshaft clockwise. Set the No. 1 cylinder to TDC/compression, check and adjust valve clearance, install the cylinder head cover sub-assembly after removing old packing material and applying seal packing (Toyota Genuine Seal Packing Black, Three Bond 1207B or equivalent) to the specified locations, install the cylinder head cover gasket and sub-assembly with 8 bolts and 2 nuts at the specified torque values, install the engine wire harness brackets, connect the ventilation hoses, and proceed to install the Spark Plug, Ignition Coil assembly, inspect for oil leaks, inspect ignition timing, install the No. 1 engine cover sub-assembly, and finally install the engine under cover RH.
