• Q: How to install the camshaft on 2010 Toyota Yaris?

  A: Begin by installing the camshaft timing gear assembly onto the camshaft where the released lock pin enables insertion of the straight pin into the groove through clockwise rotation together with gentle pushing force. Tighten the flange bolt to 64 Nm (653 kgf-cm, 47 ft-lbf) without using a locking procedure during the tightening process. Verify the absence of gaps between the gear flange and camshaft before this tightening stage. The assembly requires proper movement through the retard pathway as operators must lock it in the most retarded position. The next step requires a thin layer of engine oil on the camshaft and journals together with chain installation on the timing gear where paint marks should be aligned with timing marks followed by checking the front marks on camshaft bearing cap No. 2 before applying equal torque of 13 Nm (129 kgf-cm, 9.4 ft-lbf). When working on camshaft No. 2 install the sprocket first and attach the chain to position its timing mark with the paint mark before tightening bearing caps No. 1 and No. 2 to 13 Nm. The hexagonal lobe of camshaft No. 2 requires holding during flange bolt tightening to 64 Nm (653 kgf-cm, 47 ft-lbf). Then remove the bar from the timing chain tensioner and align the crankshaft damper timing notch with the oil pump timing mark "0" and check all timing marks are in proper position. Using a screw plug and an 8 mm hexagon wrench apply adhesive to the threads before installing it with 15 Nm (153 kgf-cm) torque (11 ft-lbf). Complete the engine installation by attaching the negative battery terminal with a torque of 5.4 Nm (55 kgf-cm, 48 in-lbf) then inspect for any oil leakage before installing all remaining parts.
