rod bolts involves an initial "stretch" or seating step that is not required for used bolts. Industrial Parts Depot Tighten capscrews in numerical sequence (1-2-3-4) to [40 N•m]. all capscrews completely in numerical sequence. Retighten in numerical sequence to [70 N•m]. Verify that all capscrews are still at [70 N•m]. Rotate all capscrews an additional 60 degrees in numerical sequence. Main Bearings Rotate the capscrews in numerical sequence by an
Like the main bearings, the rod bearing cap bolts and studs should be tightened in a specific sequence to ensure even pressure distribution. The recommended sequence is:
⚠️ These specs assume you are using new OEM-specified torque-to-yield (TTY) or standard bolts. Never reuse main or rod bolts on an ISX. The process is as important as the final torque.
