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

  A:

  The proper starting position for the timing chain installation of the 1NZ-FXE engine requires setting No. 1 cylinder to 20 degrees ATDC and placing the crankshaft within 40 to 140 degrees ATDC range with all camshaft timing sprockets set to 20 degrees ATDC. Install the crankshaft between 40 and 140 to ensure 20 degrees ATDC topping point. The no. 1 cylinder should be set to 20 degrees ATDC and both intake and exhaust camshaft timing sprockets should be measured at 20 degrees ATDC marks should be set on the crankshaft before the reset. ATDC. ATDC before resetting the crankshaft to 20 degrees ATDC. To install the chain vibration damper apply 2 bolts that need 9.0 Nm (92 kgf-cm, 80 in-lbf) torque. Afterwards, position the timing marks on the camshaft timing sprocket and camshaft timing gear and crankshaft timing sprocket to match the yellow-marked timing chain. Finally, tighten the chain tensioner slipper with a bolt at the same torque value. After moving the stopper plate you need to free the plunger while pressing it inside before dropping the stopper plate to lock the plunger and insert a 3.0 mm (0.118 in.) diameter bar through the stopper plate hole followed by securing it with 2 bolts at 9.0 Nm (92 kgf-cm, 80 in-lbf). The installation process begins with tension checks between the intake and exhaust camshaft timing sprockets followed by the sequence of oil pump seal then timing chain cover then Crankshaft Position Sensor and lastly the camshaft timing oil control valve assembly. First, install the engine mounting bracket using 4 bolts at 55 Nm torque and then place the engine mounting spacer with 2 bolts at the same torque before installing the engine mounting insulator RH with 3 bolts and 4 nuts at 52 Nm torque. Position the straight pin hole of the crankshaft damper accurately and install the pulley while using Special Service Tool: 09213-58013 91111-50845 along with the tool to tighten the crankshaft bolt to 128 Nm (1,305 kgf-cm, 95 ft-lbf). Ensure the chain cover stays clear. After the Water Pump installation proceed with Drive Belt addition followed by checking the drive belt tension. You must install the purge VSV along with the cylinder head cover where you should use Toyota Genuine Seal Packing Black or Three Bond 1207B equivalent seal packing applied at two specified locations before installation of nine bolts and two nuts secured together at 10 Nm (102 kgf-cm, 7.4 ft-lbf). Safely attach the Ignition Coil as well as the brake master cylinder reservoir cover and wire harness before connecting the Fuel Injector along with ignition coil connectors. Equip the windshield washer jar with two bolts united by a specified torque then connect the reservoir bracket followed by the brake master cylinder reservoir and No. 2 air cleaner inlet and air cleaner assembly with correct torque specifications. The last manufacturing stages of assembly focus on installing the front cowl top panel outer, windshield Wiper Motor with wiper link assembly and cowl top ventilator louvers along with hood to cowl top seal and front wiper arms with wiper arm head caps. The last steps include attaching the negative battery terminal cable before installing both rear floor boards and engine coolant and leak inspection followed by support opening cover and under cover installation before proceeding with the front wheel mount and negative terminal initialization.
