Connecting Rod Bolt Torque Specs & Clearances - 8740 Cap Screw Instruction Sheet

This document is a photographed page from an aftermarket connecting rod installation instruction sheet, shown alongside two twelve-point connecting rod cap screws (bolts) laid on the paper. The page warns about residues that may cause gouging and seizing on threads, then lists the oil clearances the installer must verify: rod bearing clearance of 0.002-0.003", small end clearance of 0.0009-0.0015" for floating-pin type, 0.0006-0.0009" (smaller than pin) for press-fit type, side clearance of 0.015-0.025", and a reminder to use a narrow bearing on larger journal radii. It then gives torque specifications for 8740 chromoly cap screws when lubricated with moly lube: 8mm at 30-35 ft-lbs (elongation 0.0055-0.0070"), 9mm at 40-45 ft-lbs (0.0055-0.0065"), 5/16" at 30-35 ft-lbs (0.0060-0.0070"), 3/8" at 40-45 ft-lbs (0.0050-0.0060"), and 7/16" at 65-70 ft-lbs (0.0065-0.0075"). A note adds 10 ft-lbs to torque values if motor oil is used instead of moly lube. The page ends by instructing that original cap-and-rod pairs must stay together because they are honed together at the factory.
