ENGINE BLOCK
DESCRIPTION
The cylinder block (Fig. 53) is made of heat treated
aluminum with cast-in-place iron liners. The block is
a closed deck design with the right bank forward. To
provide high rigidity and improved NVH, the block
has cast-in contours and ribs, along with powdered
metal 6 bolt main caps (4 vertical, 2 horizontal), with
a die cast aluminum structural beam windage tray
mounted to the main caps.
STANDARD PROCEDURE - CYLINDER BORE
HONING
(1)
Used carefully, the cylinder bore resizing hone,
recommended tool C-823 or equivalent, equipped with
220 grit stones, is the best tool for this honing proce-
dure. In addition to deglazing, it will reduce taper and
out-of-round as well as removing light scuffing, scor-
ing or scratches. Usually a few strokes will clean up a
bore and maintain the required limits.
