Construction
The H-Series design features increased crush, medium eccentricity, and enlarged edge chamfers for crankshaft fillet clearance. Confirm compatibility with the actual crankshaft fillet and block configuration rather than relying on engine family alone.
Before Ordering and Assembly
This is the standard-size CAL-MS2199H listing, not the HX extra-clearance version. Confirm block main housing dimensions, crankshaft journal dimensions, and thrust configuration before purchase.
Professional installation is recommended. Measure each installed bearing bore and verify actual oil clearance after the main caps are torqued to the applicable assembly specification. Coating adds material to the bearing surface and can affect measured clearance; it does not replace correct lubrication or clearance verification.
