2002 Toyota Camry Parts Questions & Experts Answers

• Q: How to replace the timing chain on 2002 Toyota Camry?

  A: The replacement process for the timing chain starts by taking out the hood sub-assembly followed by the front wheel RH and engine under covers LH and RH and front fender apron seal RH. Lift the crankshaft pulley with a bar until the mark lines up with the timer mark. Proceed by replacing the engine oil drain plug with a new gasket then tighten it to 25 Nm (255 kgf-cm, 18 ft. lbs.). First remove the exhaust pipe assembly front. Then eject the engine moving control rod with bracket (using 3 bolts) and separate both engine mounting stay No. 2 RH and engine mounting bracket No. 2 RH from the system. The following step entails removing the fan and generator V belt while extracting engine cover sub-assembly No. 1 from its position. The service procedure requires disconnection of engine wire followed by generator assembly removal and vane pump assembly disassembly without breaking the hose connection. Release the ignition coil assembly while you disconnect ventilation hoses and then remove the cylinder head cover sub-assembly through bolt removal and then unclamping the engine wire harness followed by 8 bolts and 2 nuts. To remove the crankshaft pulley set No. 1 cylinder to TDC/compression while using Service Tools 09213-54015 (91651-60855 and 09330-00002 to loosen the pulley bolt and Special Service Tools 09950-50013 (09951-05010, 09952-05010, 09953-05020, 09954-05021 to remove it. The crankshaft pulley removal requires Special Service Tool: 09960-10010 (09962-01000, 09963-01000) in combination with Special Service Tool: 09950-40011 (09951-04010, 09952-04010, 09953-04030, 09954-04010, 09955-04041, 09957-04010, 91111-51014). Use Special Service Tool: 09032-00100 with 2 nuts and 12 bolts to remove oil pan sub-assembly while cutting off the applied sealer. Exercise caution to prevent damaging the surface areas where the cylinder block meets the oil pan. Two nuts must be removed from chain tensioner assembly No. 1 while avoiding crankshaft rotation without the chain tensioner present. Assembly the belt tensioner V-ribbed assembly followed by engine hanger number 1 and 2 which should be torqued to 38 Nm (387 kgf-cm, 30 ft. lbs.) using parts Engine hanger No.1 12281-28010, Engine hanger No.2 12282-28010, Bolt 91512-061020. The ride starts with attaching the engine chain hoist to engine hangers before taking off the bolt which allows you to disconnect both the engine mounting insulator together with the steering gear return hose clamp from the frame. After this you can easily take out the 4 nuts from engine mounting insulator RH and use the hoist to raise the engine to remove engine mounting insulator RH. Start by removing the engine mounting bracket RH through three bolts and afterward disconnecting the timing chain or belt cover sub-assembly by taking off the cylinder block stud bolt for the drive belt tensioner and fourteen bolts and two nuts while being careful about the timing chain cover. Start by removing the crankshaft position sensor plate No. 1 together with the chain tensioner slipper, the chain vibration damper No. 1, chain sub-assembly and crankshaft timing gear or sprocket. To service No. 2 chain sub-assembly the mechanic must turn the crankshaft counterwise by 90° to match the oil pump drive shaft gear with the oil pump groove. Next they should maintain position with a 4 mm bar while removing the nut, bolt, chain tensioner plate and spring. The installation of No. 2 chain begins when you insert the crankshaft key left horizontally to line up mark links with timing marks while temporarily fastening the oil pump drive shaft gear before fixing the chain tensioner plate. Torque the chain tensioner plate to 12 Nm (122 kgf-cm, 9 ft. lbs.) and the oil pump drive shaft gear nut to 30 Nm (301 kgf-cm, 22 ft. lbs.). Drive the crankshaft to align the key position at the top of its path. Place chain vibration damper No. 1 at 9.0 Nm (92 kgf-cm, 80 inch lbs.) then set No. 1 cylinder to TDC/compression position while timing marks of the camshaft timing sprockets match with No. 1 bearing caps. First use Special Service Tool: 09309-37010 to fit the sprocket before you align each mark link with the corresponding timing marks of the camshaft timing gear while adding the chain. Put the chain tensioner slipper in place followed by torquing it to 19 Nm (194 kgf-cm, 14 ft. lbs.). Then install the crankshaft position sensor plate by placing its "F" mark forward. Use the clean contact surface of the timing chain or belt cover sub-assembly then install it with 14 bolts and 2 nuts while torquing at specified values after applying seal packing. The installation order includes the V-ribbed belt tensioner assembly followed by the engine mounting bracket RH and the engine mounting insulator RH while torquing every bolt to specified values. The oil pan sub-assembly requires cleaning of its contact surface before receiving seal packing for installation using 12 bolts and 2 nuts tightened to 9.0 Nm (92 kgf-cm, 80 inch lbs.). Use appropriate Special Service Tools to install chain tensioner assembly No. 1 and crank position sensor along with crankshaft pulley according to specified torque values. After completion, the technician will install the cylinder head cover sub-assembly and its components, including the ignition coil assembly and vane pump assembly, generator assembly, engine wire, engine mounting stay No. 2 RH and fan and generator V belt, engine mounting bracket No. 2 RH, engine moving control rod with bracket, exhaust pipe assembly front, front wheel RH, and hood sub-assembly while torquing according to specifications before adding engine oil and inspecting for any oil leakage.
