• Q: How to replace the timing chain on 2005 Toyota Camry?

  A: The replacement procedure for a timing chain starts with unfastening the hood sub-assembly along with front wheel RH, engine under covers LH and RH, and front fender apron seal RH. The oil draining process must be followed by installing a new gasket and drain plug which requires torquing at 25 Nm (255 kgf-cm, 18 ft. lbs.). The first step in the procedure involves removing the exhaust pipe assembly front followed by the engine moving control rod with bracket (after removing all three bolts) as well as the engine mounting stay No.2 RH, engine mounting bracket No.2 RH, fan and generator V belt and finally the engine cover sub-assembly No.1. Detach the engine wire before removing the generator assembly together with the vane pump assembly while maintaining the hose connection. The mechanic should uninstall the ignition coil assembly together with ventilation hoses and cylinder head cover sub-assembly after removing 8 bolts and 2 nuts. Place the No.1 cylinder at TDC/compression before removing the crankshaft pulley with Special Service Tool. After the tool removal, proceed to remove the crankshaft position sensor and oil pan sub-assembly by using Special Service Tool: 09032-00100 to cut through the sealer. The process requires removal of 12 bolts and 2 nuts. The installation process includes fitting engine hangers with bolts which require torquing at 38 Nm (387 kgf-cm, 28 ft.lbs.) tension setting. Also install the V-ribbed belt tensioner assembly by removing the bolt, nut, and tensioner and chain tensioner assembly No.1 with two nut removals. Use a chain hoist on engine hangers while disconnecting the engine mounting insulator FR and the engine lateral control rod along with steering gear return hose clamp. Proceed by disconnecting the engine mounting bracket RH through its 3 bolts and timing chain or belt cover sub-assembly by unfastening the stud bolt for drive belt tensioner and 14 bolts and 2 nuts. First carefully pry the timing chain cover before removing the crankshaft position sensor plate No.1 together with chain tensioner slipper, chain vibration damper No.1, chain sub-assembly and crankshaft timing gear or sprocket. The crankshaft must be rotated counterclockwise by 90 degrees before securing the oil pump driven sprocket with a 4 mm bar. Afterward, specialists should remove the nut along with bolt and chain tensioner plate as well as spring. The installation of the No.2 chain sub-assembly requires positioning the crankshaft key at its left horizontal position followed by timing mark alignment and sprocket and chain insertion before temporarily tightening the oil pump driven sprocket and installing the chain tensioner plate at 12 Nm (122 kgf-cm, 9 ft. lbs.). First step to set the adjusting hole of the oil pump driven sprocket properly into the groove before tightening it with a 4 mm bar and securing the nut at 30 Nm (301 kgf-cm, 22 ft. lbs.). Skew the crankshaft to a 90° rotation until the crankshaft key aligns itself at the top position. The technician must install chain vibration damper No.1 with 9.0 Nm torque (92 kgf-cm, 80 inch lbs.) before aligning timing marks on the chain sub-assembly while tightening the chain tensioner slipper to 19 Nm (194 kgf-cm, 14 ft. lbs.). Next they must install the crankshaft position sensor plate No.1 which has an F mark facing forward followed by timing chain or belt cover sub-assembly installation using 14 bolts, two nuts, and specified torques after removing old packing and applying new seal packing (Part No. 08826- Integrate the V-ribbed belt tensioner assembly first (torque to 59.5 Nm (607 kgf-cm, 44 ft. lbs.)) followed by the installment of engine mounting bracket RH (3 bolts torqued to 54 Nm (551 kgf-cm, 40 ft. lbs.)) then adding engine mounting insulator with 4 nuts torqued to 95 Nm (969 kgf-cm, 70 ft. lbs.) for nut A and 87 Nm (888 kgf-cm, 64 ft. lbs.) for nut B. Reinstall the steering gear return hose clamp and engine mounting insulator FR and the engine lateral control rod that applies to M/T vehicles. Position the oil pan sub-assembly by first removing the old packing material followed by packing installation and securing it with 12 bolts and 2 nuts (torque: 9.0 Nm (92 kgf-cm, 80 inch lbs.)). Place chain tensioner assembly No.1 along with crankshaft position sensor (torque 9.0 Nm) and crankshaft pulley (use aligning set key during installation and torque to 170 Nm). Finally, reinstall the cylinder head cover sub-assembly, ignition coil assembly (torque: 19 Nm (194 kgf-cm, 14 ft. lbs.)), vane pump assembly, generator assembly, engine wire, fan and generator V belt, engine mounting bracket No.2 RH (torque: 52 Nm (531 kgf-cm, 38 ft. lbs.)), engine mounting stay No.2 RH (torque: 64 Nm (653 kgf-cm, 47 ft. lbs.)), engine moving control rod with bracket (torque: 64 Nm (653 kgf-cm, 47 ft. lbs.)), exhaust pipe assembly front, front wheel RH, and hood sub-assembly (torque: 13 Nm (133 kgf-cm, 10 ft. lbs.)), then add engine oil and check for leaks.
