2006 Toyota RAV4 Parts Questions & Experts Answers

• Q: How to remove the timing chain on 2006 Toyota RAV4?

  A: A safe procedure for timing chain removal starts with disconnecting the battery cable from the negative terminal and allowing a minimum 90-second wait before continuing. Begin removal tasks by taking off 2 nuts from the radiator support opening cover, front wheel RH, No. 1 engine under cover, front fender apron RH and No. 1 engine cover. Start by draining engine oil then unfasten the front exhaust pipe together with front suspension member reinforcement RH and fan and generator V belt before removing the generator assembly and radiator reservoir by their respective 2 bolts. You must disconnect the wire harness protector bolt and the 2 engine wire clamps to remove the engine mounting insulator RH and then support the engine through a transmission jack to remove the 4 bolts and 2 nuts. The same procedure must be repeated for the engine mounting insulator FR by removing its through bolt and nut and both bolts. The technician should commence the removal procedure by first unfastening the idler pulley and ignition coil assembly and spark plug before moving to the cylinder head cover sub-assembly step to disconnect 2 ventilation hoses and engine wires along with the removal of 8 bolts and 2 nuts. Attach a sling tool before uninstalling the 12 bolts and 2 nuts securing the oil pan sub-assembly while executing the special service tool 09032-00100 to cut the applied sealer and remove the assembly from the vehicle without harming contact surfaces. TDC/compression alignment of cylinder No. 1 requires positioning the crankshaft pulley groove with "0" mark while verifying sprocket and timing gear alignment. Remove the crankshaft pulley with Special Service Tools: 09213-54015 (91651-60855), 09330-00021, and then optionally use 09950-40011 (09957-04010) 09950-50013 (09951-05010, 09952-05010, 09953-05020, 09954-05021). The No. 1 chain tensioner assembly together with the engine mounting bracket RH and V-ribbed belt tensioner assembly must be removed before using the transmission jack to lift the engine. Use an E 10 torx socket to remove the timing chain cover sub-assembly while being cautious to preserve the contact surfaces. Turn the crankshaft 90 degrees counterclockwise to access the bolted items that include the No.1 crankshaft position sensor plate, timing chain guide, chain tensioner slipper, No.1 chain vibration damper, chain sub-assembly and crankshaft timing sprocket, No.2 chain sub-assembly. Use a 4mm diameter bar to lock the oil pump drive shaft sprocket for all component removals.
