Outboards 00001, 2 and 3 were run to death and torn down for analyses. Outboards 00004 through 05000 had the power heads replaced under warrantee. The suppliers specifications changed and the new bearings had the same part number abut were better quality. The only ’56 early serial number Big Twins that you would find with bad wrist pins today would be in an old dealers back room still in the sealed factory box. Any one who didn’t read there mail and ordered the bearings to fix a damaged motor under warrantee was sent a new powerhead.
