• Q: How to remove the timing chain on 2009 Toyota 4Runner?

  A: The procedure of timing chain removal on the 1GR-FE engine begins with disconnecting first the power steering link assembly followed by differential carrier assembly front installation for 4WD then draining engine coolant and oil. Start by taking out both the battery and the V-bank cover then continue with the removal of the radiator support seal upper by unclipping its 11 fasteners. Start by releasing the fluid coupling assembly and then take off the fan and generator V belt before proceeding to remove the fluid coupling assembly. The air cleaner assembly along with the oil level gauge guide and water inlet needs removal after disconnecting the No. 2 ventilation hose. The vane pump assembly requires disconnecting the P/S oil pressure switch connector as well as removing its 2 bolts while safeguarding the pulley from contact with all other components. The service technician should take apart the generator assembly together with the cooler compressor assembly and V-ribbed belt tensioner assembly while removing the No. 2 and No. 1 idler pulley sub-assemblies. Special Service Tools: 09213-54015 91651-60855 along with a pulley set bolt are required to remove the crankshaft pulley through its set bolt and Special Service Tool: 09950-50013. Removal of the No. 2 oil pan sub-assembly requires unfastening its 10 bolts, 2 nuts, removing the applied sealer, and maintaining safe contact surface integrity. The service must continue with the removal of the oil strainer sub-assembly and the oil pan sub-assembly and the intake air surge tank along with the ignition coil assembly and two cylinder head cover sub-assemblies. Detach the camshaft timing oil control valve assembly by removing its 2 connectors and 2 bolts and 2 valves. Commence the process by taking away the VVT sensor as well as the timing chain or belt cover sub-assembly followed by separating the timing gear case or timing chain case oil seal. To set the No. 1 cylinder for TDC/compression position install the crankshaft pulley set bolt and put the crankshaft set key at the timing line of the cylinder block and make sure camshaft timing gears match the bearing caps. The crankshaft needs one complete revolution before obtaining correct timing mark alignment. Proceed with caution when removing the No. 1 chain tensioner assembly because rotating the crankshaft should not occur without the tensioner in place. Continue to fix the stopper plate by pushing the plunger inside during the process. The procedure requires users to remove the 2 bolts and chain tensioner along with the chain tensioner slipper and No. 1 idle gear shaft using a 10 mm hexagon wrench followed by the removal of the No. 2 chain vibration damper before collecting the chain sub-assembly.
