  1. Prepare for installation of the automatic belt tension adjuster assembly. CAUTION: Always use a vertical type pressing tool to move the adjuster rod down. Do not use a lateral type vise. Push the adjuster rod vertically. Press-in the push adjuster rod gradually taking three minutes or more. Do not allow press pressure to exceed 9,807 N (1,000 kgf, 2,205 lbf). Push in the adjuster rod to the end face of the cylinder. However, do not press the adjuster rod below the end face of the cylinder. Doing so may damage the cylinder. Do not release the press pressure until stopper pin is completely inserted. Attach the automatic belt tension adjuster assembly to vertical pressing tool. Slowly push in the adjuster rod with a pressure of 165 N (16.8 kgf, 37.1 lb) or more until the adjuster rod is aligned with the stopper pin hole in the cylinder. With a 2 mm (0.08 in) dia. stopper pin or a 2 mm (nominal) dia. hex wrench inserted into the stopper pin hole in cylinder, secure the adjuster rod.

  2. Align the mark (A) on crank sprocket with the mark on oil pump cover at cylinder block.
  3. Align the single line mark (A) on the exhaust cam sprocket RH with notch (B) on the timing belt cover.
  4. Align the single line mark (A) on the intake cam sprocket RH with notch (B) on the timing belt cover. Make sure that the double lines (C) on the intake and exhaust camshaft sprockets are aligned.
  5. Align the single line mark (A) on exhaust cam sprocket LH with notch (B) on the timing belt cover by turning the sprocket counterclockwise (as viewed from front of engine).
  6. Align the single line mark (A) on intake cam sprocket LH with notch (B) on the timing belt cover by turning the sprocket clockwise (as viewed from front of engine). Make sure the double line marks (C) on the intake and exhaust cam sprockets are aligned.
  7. Make sure that the cam and crank sprockets are positioned properly. CAUTION: Intake and exhaust camshafts for this DOHC engine can be independently rotated with the timing belts removed. As can be seen from the figure, if the intake and exhaust valves are lifted simultaneously, the valve heads will interfere with each other, resulting in bent valves. When the timing belts are not installed, four camshafts are held at the "zero-lift" position, where all cams on camshafts are not pushing down on the intake and exhaust valves. (Under this condition, all valves remain unlifted). When the camshafts are rotated to install the timing belts, #2 intake and #4 exhaust cam of camshaft LH are held, pushing their corresponding valves down. (Under this condition, these valves are held lifted). Camshaft RH are held so that their cams do not push the valves down. Camshafts LH must be rotated by the smallest possible angle from zero-lift position to where the timing belt can be installed, in order to prevent mutual interference of intake and exhaust valve heads. Do not allow the camshafts to rotate in the direction shown in the upper figure. Doing this may cause both the intake and exhaust valves to lift simultaneously, resulting in mutual interference of heads.
  8. Install the timing belt. Align the alignment mark on the timing belt with marks on the sprockets in the alphabetical order shown in the figure. While aligning marks, position the timing belt properly. CAUTION: If the timing belt slips by 1 or more teeth, the valve and piston may hit each other. Make sure that the direction of belt rotation is correct.
  9. Install the belt idlers. Tightening torque: 39 N.m (4.0 kgf-m, 28.8 ft-lb) NOTE: Make sure that the marks on the timing belt and sprockets are aligned.
  10. After ensuring that the marks on the timing belt and sprockets are aligned, remove the stopper pin from tensioner adjuster.
