A78326 Turn A05052 A52840 A78327 Approx. 60_ Turn 3MZ–FE: 14–46 – ENGINE MECHANICAL PARTIAL ENGINE ASSY (1MZ–FE/3MZ–FE) LEXUS RX330/RX300 REPAIR MANUAL (RM1024E) 18. REMOVE TIMING BELT (a) Set No. 1 cylinder to TDC/compression. (1) Temporarily install the crankshaft pulley bolt and washer to the crankshaft. (2) Turn the crankshaft clockwise, and align the timing mark of the crankshaft timing pulley with the oil pump body. (3) Check that timing marks of the camshaft timing pulleys and No. 3 timing belt cover are aligned. If not, turn the crankshaft 1 revolution (360_). (4) Remove the crankshaft pulley bolt. (b) If re–using the timing belt, check that there are 3 installation marks on the timing belt as shown in the illustration. (1) If the installation marks have disappeared, put new installation marks on the timing belt before removing. (c) 3MZ–FE: Set No. 1 cylinder to approximately 60_BTDC/ compression. (1) Turn the crankshaft counterclockwise by approximately 60_. NOTICE: If the timing belt is disengaged, having the crankshaft pulley at the wrong angle can cause the piston head and valve head to come into contact with each other when you remove the camshaft timing pulley and camshaft, causing damage. So always set the crankshaft pulley at the correct angle. (d) Remove the timing belt tensioner. NOTICE: Do not reinstall the tensioner with its plunger extended.

REMOVE WATER PUMP ASSY (a) Remove the 3 bolts and 3 nuts, then remove the water pump and the gasket. 27. REMOVE CAMSHAFT NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being removed. If the camshaft is not kept level, damage to the cylinder head or to the camshaft may result. To avoid this, the following steps should be carried out. (a) Align the timing marks (2 dot marks) of the camshaft drive and the driven gears by turning the camshaft with a wrench. (b) Secure the exhaust camshaft sub–gear to the main gear with a service bolt. Torque: 5.4 N⋅m (55 kgf⋅cm, 48 in.⋅lbf) Recommended service bolt Thread diameter 6 mm Thread pitch 1.0 mm Bolt length 16 to 20 mm HINT: When removing the camshaft, make certain that the torsional spring force of the sub–gear has been eliminated by installation of the service bolt. (c) Using several steps, loosen and remove the 10 bearing cap bolts uniformly in the sequence shown in the illustration. Remove the 5 bearing caps and the camshaft. NOTICE: S Do not pry out the camshaft. S Be careful not to damage the portion of the cylinder head receiving the shaft thrust.

REMOVE NO.2 CAMSHAFT (a) Using several steps, loosen and remove the 10 bearing cap bolts uniformly in the sequence shown in the illustration. Remove the 5 bearing caps and the No. 2 camshaft. NOTICE: S Do not pry out the camshaft. S Be careful not to damage the portion of the cylinder head receiving the shaft thrust. (b) Remove the oil seal from the No. 2 camshaft. 29. REMOVE NO.3 CAMSHAFT SUB–ASSY NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being removed. If the camshaft is not kept level, damage to the cylinder head or to the camshaft may result. To avoid this, the following steps should be carried out. (a) Align the timing marks (1 dot marks) of the camshaft drive and the driven gears by turning the camshaft with a wrench. (b) Secure the exhaust camshaft sub–gear to the main gear with a service bolt.
