Rod Bolt Stretch Monitoring Chart - 8-Rod V8 Connecting Rod Bolt Record Sheet

This document is a blank 'Rod Bolt Stretch Monitoring Chart,' a worksheet used during engine assembly to record connecting rod bolt stretch measurements. It provides a grid of eight boxes, one for each connecting rod (ROD #1 through ROD #8), consistent with a V8 engine. Each rod's box contains fill-in lines for both the INSIDE BOLT and the OUTSIDE BOLT, with 'IN' and 'OUT' blanks for each bolt so the builder can log the bolt's free (unstretched) length and its stretched (torqued) length, or install/removal measurements. A red warning printed vertically along the left edge (partially cut off in the scan) states that if bolts have exceeded a certain amount over the original measurement they should be replaced IMMEDIATELY, because they have gone past their yield point and are prone to failure. No measurements have been filled in on this copy; all blanks are empty. The chart contains no vehicle year, make, model, part numbers, or torque values — it is a generic record-keeping form typically packaged with aftermarket connecting rods or rod bolts. A reader can use it as a template for tracking rod bolt stretch across engine rebuilds.
