torquing con rods

Hello all .
Wondering when torquing up conrod bolts to crankshaft do the rods need to be supported in any way or just let the twist load apply onto the bearings .

Few builders are concerned with this. If you are. Use the correct feeler gauge between the rods to eliminate side twist while torquing.

Use a minimum of .010" feeler blade. It must be hardened steel (NOT the brass one). "Whack" the rod pair back and forth a couple times with a soft hammer (we use plastic so no debris comes off). Place the blade between the rod and the crank, where, when you turn to torque, the pressure is against the blade and the crank. When it "snaps" torque, move to the next bolt. "Torque" all the rod bolts (both rods) twice while you're "there" (don't loosen them, just hit them again). This will "square up" the rods to each other, a MOST important aspect of a good build. Educated builders are VERY concerned with this.
