21. Install the bearing caps, screw in the bolts and tighten them by hand.
22. Tighten the bearing cap bolts evenly and in the prescribed sequence in several stages to the prescribed torque specified in the Specifications at the beginning of this chapter (Fig. 7.22).
Fig. 7.22. Sequence of tightening the camshaft bearing cap bolts
23. Engage the teeth of the camshaft sprockets with the timing chain so that the marks made during removal are aligned with the upper timing marks on the sprockets, then place the sprockets on the pins on the camshaft hubs, screw in the sprocket mounting bolts and tighten them by hand. At this point, the mark on the crankshaft pulley should be aligned with the "0" mark on the timing chain cover, the TDC marks on the camshaft sprockets should be aligned and parallel to the upper edge of the timing chain cover, and the mating marks on the timing chain should be aligned with the upper marks on the sprockets, and all the slack in the chain should be on the side of the engine where the tensioner is located (fig. 7.4).
24. Double check that the sprockets are returned to the camshafts from which they were removed and tighten the sprocket mounting bolts to the specified torque shown in the Specifications at the beginning of this chapter.
25. Install the timing chain tensioner as described in p.p. 38 and 39 paragraph 6.
26. The rest of the installation is carried out in the reverse order of removal.
