  Q: How to service the timing chain on Toyota Corolla?

  A:

  Service of the 1ZZ-FE timing chain starts with disconnecting the battery negative terminal followed by unbolting the front right wheel and engine under cover and cylinder head cover No.2 while removing their 2 nuts and 2 clips. The procedure starts by draining engine coolant and removing the fan combined with the generator V belt and disconnecting the vane pump assembly and generator assembly. Detailed service of the 1ZZ-FE engine timing chain begins with removing the engine mounting insulator RH using unfastened oil reservoir bracket No.1 bolts and engine supports through a wooden block resting atop a jack. Follow the steps by disconnecting four Ignition Coil connectors before removing two nuts followed by the removal of four ignition coils. You should detach ventilation hoses before unbolting the cylinder head cover sub-assembly together with its clamp brackets to remove the assembly. Detach the elements that include the V-ribbed belt tensioner assembly with the engine mounting bracket RH along with the Water Pump assembly while pulling apart the Crankshaft Position Sensor. To set the Number 1 cylinder at TDC compression position put the crankshaft pulley timing marks at "0" while maintaining appropriate alignment of the camshaft timing gears. The removal procedure begins with the crankshaft pulley's uninstallation using Special Service Tool: 09960-10010 (09962-01000, 09963-01000) followed by the chain tensioner assembly No.1 but attention must be paid to avoid turning the crankshaft without it. Gently detach the timing chain or belt cover sub-assembly by unbolting it while carefully prying it off before removing both the timing chain or belt cover oil seal. Pry out the chain sub-assembly while protecting the engine using 2 screwdrivers after removing the crankshaft position sensor plate No.1 and the chain tensioner slipper. The new chain sub-assembly installation requires the No.1 cylinder to reach TDC/compression position with camshaft timing gears properly aligned before using Special Service Tool: 09223-22010 to set the crankshaft timing gear. Install the chain tensioner slipper and crankshaft position sensor plate No.1 followed by the timing chain or belt cover oil seal while verifying that the oil seal faces the cover edge. Seal packing, Water pump Part No.08826-00100 or equivalent for timing chain cover and part No.08826-00080 or equivalent for the other part, needs application before bolt and nut installation with specified torque. Take the chain tensioner assembly No.1 with its clean lubricated O-ring then use Special Service Tool: 09960-10010 (09962-01000, 09963-01000) to install and torque the crankshaft pulley correctly. Set in position all components starting with the crankshaft position sensor together with the water pump assembly, engine mounting bracket RH, V-ribbed belt tensioner assembly and ending with the cylinder head cover sub-assembly while applying seal packing when necessary. The service procedure requires the installation of ignition coil assembly together with engine mounting insulator RH and generator assembly and vane pump assembly and fan and generator V belt. The repair process requires adding engine coolant together with reconnecting the battery negative terminal and leak inspection. Install both cylinder head cover No.2 and the front right wheel and torque all components according to their specified values.

  Q: How to install the timing chain on Toyota Corolla?

  A:

  Before installing the timing chain on the 1ZZ-FE engine technicians must set the No. 1 cylinder at TDC/compression by rotating Camshafts with hexagonal wrenches until camshaft timing gears point marks match then using the crankshaft pulley bolt to position the timing gear key against the Oil Pump point mark. Insert the timing chain onto the crankshaft timing gear so that the yellow mark link rests at the timing mark position and install the crankshaft timing gear after using Special Service Tool 09223-22010. Install the chain on the camshaft timing gears keeping the yellow mark links directly above their corresponding timing marks. A bolt should fasten the chain tensioner slipper at 18.5 Nm (189 kgf-cm, 14 ft-lbf) while installing the crankshaft position sensor plate facing forward with the "F" mark exposed. A gentle application of multipurpose grease should be used to treat the lip of a new oil seal. Then position the timing chain cover on wooden blocks after placing the tool 09223-22010 to slowly tap the oil seal until it reaches the timing chain cover edge leaving the lip clear from any foreign objects. Install the 10 bolts and 2 nuts while torquing Bolt A and nut A to 13 Nm (133 kgf-cm, 10 ft-lbf) and Bolt B to 18.5 Nm (189 kgf-cm, 14 ft-lbf). Remove any old packing material before applying a continuous bead of seal packing with a diameter between 3.5 to 4.5 mm. Fasten the stud bolt using tool "TORX" wrench socket (E8) at 9.5 Nm (97 kgf-cm, 84 in-lbf). Install the chain tensioner assembly with two 9.0 Nm tightened nuts keeping an eye on the O-ring to avoid twisting it while the tensioner receives engine oil on its O-ring which needs to be clean to begin with. While aligning the pulley set key with its key groove you should slide on the crankshaft pulley before torquing the crankshaft pulley bolt to 138 Nm (1,407 kgf-cm, 102 ft-lbf) using Special Service Tools: 09960-10010, 09962-01000, 09963-01000. To disconnect the plunger knock pin from its hook turn the crankshaft counterclockwise while clockwise motion pushes the slipper toward the plunger. The crankshaft position sensor needs a thin oil layer on its O-ring before assembly with 2 bolts reaching 9.0 Nm (92 kgf-cm, 80 in-lbf) torque specification and Water Pump mounting. Both the engine mounting bracket RH and V-ribbed belt tensioner assembly need these torque settings: bracket at 47 Nm (479 kgf-cm, 35 ft-lbf) and tensioner assembly with bolt secured at 69 Nm (704 kgf-cm, 51 ft-lbf) while using a nut torque of 29 Nm (296 kgf-cm, 21 ft-lbf). Place seal packing on designated locations of the cylinder head cover before installing it along with 3 clamp brackets and 9 bolts and 2 seal washers and 2 nuts. Torque Bolt A and nut A to 11 Nm (112 kgf-cm, 8 ft-lbf) and Bolt B to 9.0 Nm (92 kgf-cm, 80 in-lbf). The wiring clamps need installation followed by ventilation hose connection before adding an Ignition Coil assembly which requires 4 bolts torqued to 9.0 Nm (92 kgf-cm, 80 in-lbf) and an engine wire needs 2 nuts torqued to 9.0 Nm (92 kgf-cm, 80 in-lbf). Fasten the engine mounting insulator RH through 4 bolts and 2 nuts while torquing them to 52 Nm (530 kgf-cm, 38 ft-lbf) together with the oil reservoir bracket No. 1 using 2 bolts torqued to 7.8 Nm (80 kgf-cm, 69 in-lbf). Reassemble the vane pump assembly with the generator unit before placing the fan alongside installing the generator V belt. Before continuing install the battery negative terminal with 5.4 Nm of torque (55 Kg-fcm, 48 in-lbf) while inspecting for both engine coolant and oil leaks. Then add engine coolant to the system. Install the front wheel RH while using 103 Nm (1,050 kgf-cm, 76 ft-lbf) torque and cylinder head cover No. 2 with 2 clips and nuts that should be torqued to 7.0 Nm (71 kgf-cm, 62 in-lbf).
