Confirm the set contents, bearing positions and any separate thrust components against the complete manufacturer number. The photo is representative of the part family.
Measure shaft journals, housing bores and assembled oil clearance using the engine builder’s specification. Check oil-hole alignment, groove placement and crankshaft fillet clearance before final assembly. Catalog standard dimensions must not be treated as the finished dimensions for a different repair size.
Is the year and model enough to choose this bearing? No. Match 8B663HD-STD to the exact engine and measured build specification.
What size is this listing? STD manufacturer size designation; verify the exact engine and assembled clearance.
Can I substitute a different suffix? Compare the complete grade, size, locating features and assembled clearance before substituting any bearing.
Shop ACL engine bearings, Race Series rod and main bearings, thrust washers and selected oil pumps at Black Ops Auto Works. Compare the complete manufacturer part number, engine application, bearing position and size designation before choosing parts for a rebuild. Standard-size, extra-clearance and repair-size bearings serve different measured requirements; they are not interchangeable simply because the engine family matches. ACL Rod Bearings, Main Bearings and Thrust Components Connecting-rod bearings support the crankshaft rod journals. Main bearings support the crankshaft in the block, while thrust faces or separate thrust washers control axial movement. The correct set depends on the engine version, journal dimensions, housing bore and thrust arrangement. Some applications use individual bearing pairs or selective grades rather than one complete engine set. Check the stated package quantity and full suffix before ordering. What Do ACL H and HX Mean? H identifies an ACL Race S...
