Bearing Configuration

H identifies the ACL Race Series family. Match the complete suffix to the required clearance, shell width and locating features.

Engine Application

The engine-family list identifies catalog applications, not universal vehicle fitment. Confirm the exact engine version, crankshaft, rods, block and bearing location. Vehicle names and photos do not replace dimensional verification.

Specifications

Quantity and Assembly Checks

This is an individual bearing-pair configuration. Confirm the number of pairs and selective grades required for the engine. The manufacturer catalog marks bearing wall thickness as grade-dependent. The standard housing and journal ranges do not identify a substitute grade or establish the assembled oil clearance.

Measure shaft journals, housing bores and assembled oil clearance using the engine builders 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. ACL specifies that abrasive pads or paper must not be used on the bearing surface to alter oil clearance.
