ROD BOLT INSTALLATION
When installing aftermarket rod bolts, in addition to checking the under-head radius clearance, if the nuts are flanged, always check for clearance on the cap where it seats. On some rods, the O.D. of the flanged nut will hit before the face does. It will stress the fastener and distort the housing bore when torqued. A simple piloted spot face is all that’s needed to fix the issue. A slight radius edge spot face is best, if available.
