  1. Set the No. 1 cylinder to approx. 50° BTDC/compression.Using the crankshaft damper bolt, turn the crankshaft to align the timing marks of the crankshaft timing pulley and oil pump body.Check that the timing marks of the camshaft timing pulleys and timing belt plates are aligned.If not, turn the crankshaft 1 complete revolution (360°).Using the crankshaft damper bolt, turn the crankshaft counterclockwise by approx. 50°.NOTICE: If the timing belt is disengaged, having the crankshaft pulley at a wrong angle can cause the piston head and valve head to come into contact with each other when removing the camshaft timing pulley and camshaft, causing damage. So always set the crankshaft pulley at the correct angle. 4Runner
