  Q: How to install the timing chain on Toyota FJ Cruiser?

  A:

  The procedure to install the timing chain starts with placing the chain tensioner slipper before adding the No. 1 chain tensioner assembly while pressing on the plunger to execute a clockwise stopper plate rotation followed by counterclockwise movement using a 35 mm (0.138 in.) bar to stabilize the stopper plate before tightening the two bolts to 10 Nm (102 kgf-cm, 7.4 ft-lbf). Begin by setting the No. 1 cylinder at TDC/compression, then align the timing marks of the camshaft timing gears and bearing caps. Finally, use the crankshaft pulley set bolt to align the crankshaft set key with the timing line of the cylinder block. Before installation of the chain use the crankshaft timing link and black mark links of the camshaft timing gears to position the yellow mark link with the crankshaft timing line. Install both vibration dampers before applying engine oil to the No. 1 idle gear shaft for a temporary connection with the No. 2 idle gear shaft where knock pins should match. The No. 2 idle gear shaft requires tightening with a 10 mm hexagon wrench until it reaches 60 Nm (612 kgf-cm, 44 ft-lbf) torque specification before removing the bar from the chain tensioner assembly. The assembly begins with the timing gear case or timing chain case oil seal while the next step involves installing the timing chain or belt cover sub-assembly. During this process the technician should remove old packing before installing a new O-ring on the bank 2 cylinder head. Seal packing must be applied as continuous beads between 3 to 4 mm (0.12 to 0.16 in.) length at designated areas while maintaining the seal surface oil-free before you install the timing chain cover within 3 minutes of packing application and through uniform bolt and nut tightening to 23 Nm (235 kgf-cm, 17 ft-lbf). Following the sequence install these components with the cylinder head cover sub-assemblies and water inlet and VVT sensor then camshaft timing oil control valve assembly and Ignition Coil assembly and intake air surge tank and surge tank stays as well as oil baffle plate and throttle body bracket before finally placing the air cleaner assembly. The oil pan sub-assembly procedure requires removal of used packing materials while installing a new O-ring on the oil pump followed by seal packing application before pan installation with 17 bolts and 2 nuts that should be torqued to specified amounts. Insert the oil strainer sub-assembly along with its new gasket followed by the No. 2 oil pan sub-assembly where you should include seal packing and perform uniform bolt and nut tightening. Use Special Service Tool: 09213-54015 91651-60855 to install the crankshaft pulley at 250 Nm (2549 kgf-cm, 184 ft-lbf) torque then torque the No. 1 and No. 2 idler pulleys according to their specifications. Fitting the power steering vane pump unit comes next followed by switching on the pressure sensor connector before installing the oil guide along with its new rubber ring. Use a new bolt in position A for the V-ribbed belt tensioner assembly before tightening all its bolts to required specifications. The installation process ends with the front Differential carrier assembly (applied to 4WD systems) as well as power steering link assembly (2WD and 4WD) and a battery installation. The procedure also includes coolant and engine oil and power steering fluid addition alongside differential oil for 4WD models accompanied by leak check-ups and necessary front wheel alignment inspections.

  Q: How to remove the timing chain on Toyota FJ Cruiser?

  A:

  The first step of removing the 1GR-FE engine timing chain includes disconnecting the battery and draining both oil and engine coolant. You must begin by removing the power steering link assembly on vehicles with 2WD before proceeding to remove the power steering link assembly together with the front Differential carrier assembly on vehicles with 4WD. Commence the procedure by uninstalling the fan and generator assembly followed by disassembling the cooler compressor assembly and taking out the 5 bolts from the V-ribbed belt tensioner assembly. First disconnect the power steering pressure switch connector before you separate the vane pump assembly by removing its 2 bolts. The service process requires you to first separate the No. 2 idler pulley sub-assembly from the assembly followed by removal of the No. 1 idler pulley sub-assembly. You can utilize Special Service Tool: 09213-54015 91651-60855 to stabilize the crankshaft pulley before loosening its set bolt while using Special Service Tool: 09950-50013 to extract it. Detach the No. 2 oil pan sub-assembly by uninstalling 10 bolts with two nuts and scraping off the sealer application while protecting contact surfaces from harm. The oil strainer sub-assembly requires the removal of two nuts and afterward the oil pan sub-assembly can be extracted by unfastening four housing bolts, the flywheel housing under cover, seventeen bolts, and two nuts with careful prying. Remove the air cleaner assembly with throttle body bracket followed by oil baffle plate and holding both No. 1 and No. 2 surge tank stays in position. The process includes removing the intake air surge tank and Ignition Coil assembly and camshaft timing oil control valve assembly and VVT sensor and water inlet and both cylinder head cover assemblies and timing chain or belt cover sub-assembly. Thoroughly pry off the timing chain or belt cover sub-assembly while unfastening its 24 bolts and 2 nuts before gracefully removing the O-ring in the LH cylinder head. The alignment of crankshaft set key against timing line is crucial to achieve No. 1 compression at TDC while also requiring the camshaft timing gear marks to match bearing caps. Before the crankshaft rotation start, separate the No. 1 chain tensioner assembly while fixing the stopper plate during removal of the 2 bolts. To complete the procedure remove the chain tensioner slipper while also taking away the No. 1 idle gear along with the No. 2 chain vibration damper before ending with the sub-assembly chain removal.
