Engine Cam Bearing Set SH1321S Instructions - Bearing O.D. Specs (IS706-B)

This document is an instruction slip labeled "IMPORTANT INSTRUCTIONS" packaged with an engine bearing set. It lists a table of bearing part numbers by position: SH1321S (set, standard, no O.D. listed), and individual standard-undersize sets SH1321 through SH1325, each with specified bearing outside diameter (O.D.) ranges, SH1321: 2.2041/2.2051, SH1322: 2.1490/2.1900, SH1323: 2.1740/2.1750, SH1324: 2.1590/2.1600, SH1325: 2.1440/2.1450 (all in inches). A "Note to Performance Engine Rebuilders" advises that when using these components in performance applications, the engine block should first be checked for proper housing bore alignment, and vertical oil clearance should be verified to ensure a minimum of.003 inch on each journal. The sheet footer shows document number IS706-B, "Printed in U.S.A.," and a revision date of 9/30/1999. The slip does not identify a specific vehicle make, model, engine, or year of application. Readers can learn the bearing O.D. specifications for each numbered bearing in the set and the minimum recommended vertical oil clearance for performance builds.
