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.
