How to install the camshaft on 2007 Toyota 4Runner?

Question

Accepted Answer

Install the camshaft in a level position to avoid damages to the cylinder head while positioning the mark link (yellow) on the camshaft timing gear (1-dot mark). Apply new engine oil on thrust portions and journals and fit the No. 1 chain temporarily on the No. 2 chain of the camshaft timing gear before inserting the No. 1 camshaft into its timing gear slot with the knock pin hole aligned to the No. 1 camshaft knock pin. Install the camshaft timing gear set bolt temporarily before putting the No. 1 camshaft on the RH cylinder head facing downward. Then install the 4 bearing caps in position, apply engine oil to the threads and under heads of the bearing cap bolts and uniformly tighten all 8 bolts reaching 9.0 Nm for 10 mm and 24 Nm for 12 mm head bolts. Utilizing a wrench on the hexagonal part of the No. 1 camshaft, follow by torquing the camshaft timing gear set bolt to 100 Nm while maintaining clockwise rotation for timing mark alignment. The procedure for the No. 2 chain tensioner assembly requires compressing the tensioner before inserting a 1.0 mm pin for fixation and temporarily installing the camshaft timing gear together with the No. 2 chain tensioner followed by tightening the No. 2 chain tensioner bolt to 19 Nm. Position the No. 2 camshaft on top of the RH cylinder head where the cam lobes should face upward and install the 4 bearing caps next before applying engine oil to the bearing cap bolts followed by equal tightening of all 8 bearing cap bolts. Afterward, use a clockwise rotation to align the knock pin and hold the hexagonal portion while installing the camshaft timing gear set bolt to 100 Nm before removing the No. 2 chain tensioner pin. For the No. 3 camshaft, align the mark link (yellow) with the timing mark (2-dot mark), apply new engine oil, temporarily place the No. 1 chain on the No. 2 chain, align the knock pin hole with the No. 3 camshaft's knock pin, set it onto the LH cylinder head with the cam lobes facing downward, install the 4 bearing caps, apply engine oil to the bearing cap bolts, tighten the 8 bearing cap bolts, set the paint mark of the No. 1 chain between the timing marks, and tighten the camshaft timing gear set bolt to 100 Nm. To install the No. 3 chain tensioner assembly first push it into the tensioner before inserting a 1.0 mm pin while temporarily attaching the camshaft timing gear set along with the No. 3 chain tensioner assembly then tightening the No. 3 chain tensioner bolt to 19 Nm. Drop the pin from the No. 3 chain tensioner before releasing chain tension. Afterward install the 4 bearing caps. Apply engine oil to the bearing cap bolts, then tighten the 8 bearing caps bolts to 100 Nm followed by tightening the camshaft timing gear set bolt to 100 Nm. To assemble the No. 1 chain tensioner, push in the plunger then turn the stopper plate clockwise before installing a 3.5 mm bar to lock the stopper plate and finally fastening the chain tensioner to 10 Nm torque with two bolts. Remove the bar then install new gasket combined with timing chain cover plate using four bolts tightened to 9.0 Nm torque while turning the crankshaft pulley two complete revolutions to check the timing marks. The installer must set No. 1 cylinder to TDC/compression while checking and adjusting valve clearances and installing the cylinder head cover sub-assembly LH after packing removal, seal packing application, seal washer installation, and proper torque adjustment of all 10 bolts and 2 nuts. The procedure should be repeated for the cylinder head cover sub-assembly followed by installing the ignition coil assembly with a torque of 10 Nm and installing the intake air surge tank with new gasket and tightening four bolts to 28 Nm before installation of surge tank nuts and stays and connection of various hoses and connectors. The replacement process ends with air cleaner installation and No. 2 ventilation hose connection and engine coolant addition followed by leak inspection before the installation of the V-bank cover's 2 nuts to 7.5 Nm torque and ignition timing check.
