--------------- END SUPPLEMENT ---------------Reference: Cat® Reman, 3500 Engines, SELD0164. Cat® Reman Engines, Core Acceptance Criteria, SELD0019. Core acceptance criteria specifies that the engine crankshaft can be rotated to receive a full core refund. The crankshaft has to be able to rotate to prevent transit damage and bar over in the core receiving area can occur without any damage.
If the cylinder head is removed from a 3116 or 3208 Engine, and a later decision is made to purchase a Cat® Reman engine, it is necessary that the crankshaft can be rotated before a full core refund is issued. Cores returned without a cylinder head gasket or spacers to provide cylinder head clearance, will receive a partial core refund. It is acceptable to return a core without a cylinder head gasket as long as suitable spacers or shims have been installed to allow clearance between the cylinder head and pistons when the crankshaft is rotated.
Cylinder heads for all 3500 Family Of Engines can be removed only for troubleshooting. The cylinder head must be installed on the engine with the used gaskets and original torque specifications before a full refund is issued.
