We highly recommend using a stretch gauge when installingrod bolts and other fasteners where it is possible to measure thelength of the bolt after tightening. It is the most accurate wayto determine the correct pre-load in the rod bolt. Simply followmanufacturer’s instructions, or use the chart on page 25 of thiscatalog for ARP fasteners. Measure the fastener prior to starting,and monitor overall length during installation. When the bolt hasstretched the specified amount, the correct preload, or torque,has been applied. We recommend you maintain a chart of all rodbolts, and copy down the length of the fastener prior to and after installation. If there is a permanent increase of .001? in length or more, or if there is deformation, the bolt should be replaced immediately. Don’t chance it! A sample chart is as follows: ARP offers a highly accurate stretch gauge with a dial indicator that reads in increments of .0005?. Features extra heavy springs for consistent repetition. Comes with a heavy-duty, insulated plastic carrying case for protection. A “must” for any serious engine builder.
