a. No. 3 Journal - Supported by No. I and No. 5 journals. All dimensions are in mm unless noted.
CAUTION: Install the camshafts with the alignment slots in the camshafts lined up so the Camshaft Alignment Plate can be installed without rotating the camshafts. Make sure the lobes on the No. 1 cylinder are in the same position as noted in the removal procedure. Rotating the camshafts when the timing chain is removed, or installing the camshafts 180 degrees out of position can cause severe damage to the valves and pistons.
NOTE: Lubricate the camshaft journals and bearing caps with clean engine oil.
