OEM 2007 Toyota Camry Timing Chain

2007 Toyota Camry Parts Questions & Experts Answers

• Q: How to service the timing chain on 2007 Toyota Camry?

  A: Service of the timing chain begins by disconnecting the negative cable then taking out the No. 1 engine cover sub-assembly along with front wheel RH components and engine under covers LH and RH together with front fender apron seal RH. Drain engine oil followed by removing front exhaust pipe assembly together with No. 2 engine mounting stay RH and engine moving control rod sub-assembly and No. 2 engine mounting bracket RH. You must begin by removing the V-ribbed belt with the generator assembly and vane pump assembly and ignition coil assembly together with ventilation hoses removal. First remove the cylinger head cover sub-assembly through procedures for 2 bolts and 2 engine wires followed by bolting out 8 bolts and 2 nuts. The first step is to position the No.1 cylinder at TDC/compression while you employ Special Service Tool: 09032-00100 to remove the crankshaft pulley and crank position sensor and oil pan sub-assembly by cutting through the sealer. Protect the touching surfaces from damage during this process. Tear down the No. 1 chain tensioner assembly before you put on engine hangers and raise the engine through chain block operation. Start the procedure by extracting the V-ribbed belt tensioner assembly along with the engine mounting insulator and engine mounting bracket which belongs to the right-hand side. Technological Sequence starts with the removal of timing chain cover sub-assembly along with timing chain case oil seal and then continues to remove No. 1 crankshaft position sensor plate along with chain tensioner slipper, No. 1 chain vibration damper, and timing chain guide from the system. The No. 2 chain sub-assembly becomes accessible by turning the crankshaft 90 degrees counterclockwise while using a 4 mm diameter bar to lock the oil pump drive shaft sprocket and then removing the nut, bolt, chain tensioner plate, spring, chain tensioner, oil pump driven sprocket and chain. The inspection procedure includes examining the chain sub-assemblies together with the oil pump drive sprockets and the chain tensioner slipper and vibration damper and tensioner plate and No. 1 chain tensioner. Install the sprockets with the chain while aligning the yellow mark links to the timing marks and positioning the crankshaft key horizontally to the left side. The oil pump shaft sprocket should be loosely fastened followed by insertion of the damper spring and chain tensioner plate installation with 12 Nm torque force (122 kgf-cm, 9 ft. lbs.). You should lock the oil pump drive shaft sprocket then tighten its nut to 30 Nm (301 kgf-cm, 22 ft. lbs.) afterward rotate the crankshaft clockwise through 90 degrees while aligning the crankshaft key to its top position. Fits are required for the crankshaft timing sprocket, No. 1 chain vibration damper and chain sub-assembly which needs 9.0 Nm (92 kgf-cm, 80 inch lbs.) torque. The alignment must be exact with the gold or pink mark link facing the timing mark position. The crankshaft timing sprocket needs Special Service Tool: 09309-37010 to perform tapping procedures before aligning the gold or yellow link with the timing marks. Attach the chain tensioner slipper at 19 Nm (194 kgf-cm, 14 ft. lbs.) torque followed by timing chain guide at 9.0 Nm (92 kgf-cm, 80 inch lbs.) torque and finish by securing the No. 1 crankshaft position sensor plate with "F" mark forward. Screw and tighten the timing chain case oil seal and timing chain cover sub-assembly with a V-ribbed belt tensioner assembly to 60 Nm (607 kgf-cm, 44 ft. lbs.). The engine mounting bracket RH needs 54 Nm (551 kgf-cm, 40 ft. lbs.) torque application to secure it while the engine mounting insulator RH needs specified torque values followed by the proper installation of the oil pan sub-assembly after packing with seal. Install the crank position sensor together with the crankshaft pulley and No. 1 chain tensioner assembly with correct plunger position. Complete the installation by putting the cylinder head cover sub-assembly with required torque values followed by the ignition coil assembly, vane pump assembly, generator assembly, V-ribbed belt, engine mounting components, front exhaust pipe assembly and finishing with reconnecting the negative battery terminal. Examining engine oil and exhaust gas leaks alongside ignition timing requires reinstallation of the front fender apron seal RH and engine under covers as well as front wheel RH and No. 1 engine cover sub-assembly.
