  Q: How to remove the camshaft on Toyota Camry?

  A: The first step for camshaft removal from the 2AZ-FE engine requires removal of front wheel RH, engine under cover LH, engine under cover RH and front fender apron seal RH as well as No. 1 engine cover sub-assembly, ignition coil assembly and cylinder head cover sub-assembly. Use the crankshaft pulley to find TDC/compression of the No. 1 cylinder by aligning the groove with the timing mark "0" on the timing chain cover. Verify the alignment of camshaft timing gear marks with those on the bearing caps of the No. 1 and No. 2 cylinders and the sprocket marks (if not aligned complete one revolution). Place a mark on the chain at its position relative to the timing marks. Begin by removing the No. 1 chain tensioner assembly followed by the removal of the No. 2 camshaft through the application of a wrench to loosen its camshaft timing set bolt then proceed with uniform bolt removal of the specified 10 bearing cap bolts and subsequent bearing cap removal to end the procedure. Remove the camshaft timing sprocket set bolt from its position on the No. 2 camshaft and then proceed to take out the camshaft timing sprocket when it still maintains connection with the timing chain. Rephrase the following sentence. For camshaft removal begin by loosening the 10 bearing cap bolts in sequence then remove the 5 bearing caps before extracting the camshaft and camshaft timing gear when holding the timing chain. Standby the timing chain with string support to keep it from falling off the crankshaft sprocket but shield against dropping anything within the timing chain cover. The camshaft timing gear assembly procedure involves vise-clamping of the camshaft to stop rotation along with covering all oil ports except the advance side port with vinyl tape while applying 100 kPa (1.0 kgf/cm2, 14 psi) air pressure on the open oil path through rotating the camshaft timing gear counterclockwise by hand. Protect the paths by applying a cloth before the start to prevent oil from spraying this area. To remove the camshaft timing gear flange bolt perform the operation while avoiding the removal of other 4 bolts and prepare the straight pin lock for reuse if you plan to reinstall the gear in the future.

  Q: How to install the No. 1 and No. 2 camshafts and their associated components on Toyota 4Runner?

  A: When installing the No. 1 camshaft hold it at a level position to protect the cylinder head. Together with the timing mark (1-dot mark) of the camshaft timing gear line up the mark link (yellow). After applying new engine oil to the thrust portions and journals place the No. 1 chain briefly on the No. 2 chain. Then use the knock pin hole to position the knock pin of the No. 1 camshaft into the camshaft timing gear. Start by fitting the camshaft timing gear set bolt temporarily before placing the No. 1 camshaft to the cylinder head RH with cam lobes oriented downward. Then add the 4 bearing caps to their correct spots. First cover bearing cap bolt threads and their undersurface with light engine oil before equally installing all 8 bearing cap bolts at 9.0 Nm for 10 mm heads or 24 Nm for 12 mm heads. The No. 1 camshaft should get rotated clockwise until the timing marks align before using a wrench to grip its hexagonal portion. Then tighten the camshaft timing gear set bolt to 100 Nm. Working on the No. 2 chain tensioner assembly requires first pushing the tensioner and inserting a 1.0 mm pin to secure it. Next, temporarily add the camshaft timing gear and No. 2 chain tensioner before tightening the No. 2 chain tensioner bolt to 19 Nm. The installation process for the No. 2 camshaft begins by placing it onto the right-hand cylinder head with upward-facing cam lobes then adding the bearing caps followed by engine oil distribution to the bolts before installing all 8 pieces with matching torque specifications from the No. 1 camshaft. After aligning the knock pin by turning the No. 2 camshaft clockwise you should hold it with a wrench before installing the camshaft timing gear set bolt to 100 Nm while removing the pin from the No. 2 chain tensioner. To install the No. 1 chain tensioner assembly first push the plunger while rotating the stopper plate counter-clockwise then fix the stopper with a 3.5 millimeter bar before installing the tensioner using two 10 Nm torque bolts but keep the bar in position. Finally dismantle the 3.5 millimeter bar. Apply a new gasket following installation of the timing chain cover plate with 4 bolts torqued to 9.0 Nm as you fully rotate the crankshaft pulley twice before verifying the timing mark alignment. To install the cylinder head cover sub-assembly LH start by removing old packing material and using Toyota Genuine Seal Packing Black or Three Bond 1207B equivalent and installing the sub-assembly with torques specified for the 10 bolts and 2 nuts. First bolt down the ignition coil with 10 Nm torque values then put on the intake air surge tank with new gasket and 4 bolts at 28 Nm. Finish the installation with the nuts receiving 28 Nm torque. First install necessary hoses and clamps before torquing the two V-bank cover nuts to 7.5 Nm then check for any engine coolant leaks after adding the coolant.

  Q: How to service and repair the camshaft on Toyota Tacoma?

  A: The camshaft (2TR-FE) service and repair begins with removing the negative battery cable followed by eliminating 4 bolts from the engine under cover sub-assembly Number One. The service requires draining engine coolant then separating the following elements to access the cylinder head cover sub-assembly: radiator support to frame seal LH, fan shroud, air cleaner cap sub-assembly, intake air connector, ignition coil connectors along with throttle with motor body connector, VSV connector, camshaft position sensor connector, engine wire harness clamps, ignition coils and 19 bolts and 2 nuts. Following the removal of 2 guide-bolts with an O-ring the timing chain guide can be taken out. Next, moving onto the camshaft extraction process requires setting the No.1 cylinder at TDC/compression while aligning crankshaft pulley timing mark with "0" before marking the timing chain plates and using an adjustable wrench to hold the hexagonal lobe on the No.2 camshaft while loosening the bolt which is followed by using a 10 mm socket hexagon wrench to remove the head straight screw plug. A screwdriver should be used to lift the chain tensioner stopper plate before rotating the No.2 camshaft clockwise by a small amount to push the plunger into position using a 3.0 mm (0.118 inch) diameter bar. Proceed with the camshaft timing gear removal process by uniformly loosening the 21 bearing cap bolts and afterward extracting the camshaft oil delivery pipe and O-ring before removing the camshaft bearing caps. Secure the chain with an appropriate tie to block external objects from accessing the engine compartment. Clamp the camshaft into a vise before you cover its oil paths with vinyl tape and puncture the tape to check the camshaft timing gear motion under air pressure when removing the fringe bolt. Place the camshaft timing gear on its position before gently pressing it while tightening the fringe bolt to 78 Nm (795 kgf-cm, 58 ft. lbs.). Mount the camshaft by treating it with clean engine oil and guiding the timing chain toward the camshaft timing gear before placing each camshaft bearing cap correctly with its O-ring installed. Begin by checking the specified bolt installation order then examine the timing marks before placing in the timing chain. Still one would need to integrate the timing chain guide alongside its new O-ring followed by placing the cylinder head cover sub-assembly with seal packing before torquing every bolt and nut according to specifications. The procedure requires reinstalling the intake air connector followed by the air cleaner cap sub-assembly and fan shroud then radiator support to frame seal LH while reconnecting the negative battery terminal before engine coolant addition and leak check for proper installation of engine under cover sub-assembly No. 1.
