## Discrepancy

THE CLAMPS ON THE FLEX DUCT THAT CONNECTS THE INTERCOOLER TO THE NR 1 AND NR 2 CYLINDERS ARE TOO LARGE AND BOTTOM OUT BEFORE THEY REACH THE REQUIRED TORQUE OF 30-35 PSI.  THE PARTS CATALOG CALLS OUT FOR A U84-270SH CLAMP OF THE CYLINDER AND A U84-260SH CLAMP AT THE INTERCOOLER.  IT WOULD BE BETTER IF BOTH WERE A U84-260-SH.  THIS DUCT BLEW OFF AT THE CYLINDER IN A FULL POWER TEST RUN OF NR 2 CYLINDER.
