Lock Wire

Nedd · Jul 24, 2014

I am working on a 41 SC, been a several year project. The Main and rod bolts have lock wire to help keep them from turning out. I remember using lock wire in the Navy but was wondering if I needed it on the SC rods even though they are torqued. The newer rod bolts don't have it. What do you guys do and what wire do you use? I imagine it should be high tensile stuff or something to minimize rust. The old stuff was pretty thin.

After having a wrist pin lock bolt on a DC come loose and take an 18" section out of the block and pan, we use the wires on everything with holes in the heads. Soft mechanics wire works best. It is running in oil so rust is not a concern.

I had the same issue with loosening bolts in a diff that was drilled but wire not installed. I would only use stainless safety wire, available @ NAPA or any small airport. Several diameters available. It can be twisted with NO breakage, or fear thereof. Pliers to twist the wire can be picked up off your normal tool truck, or places like Fastenal. Google Safety wire pliers..........

I order my safety wire from Aircraft Spruce. It is stainless steel and comes in several diameters. 0.032" dia. works for just about everything you will encounter in engines, army vehicles, and airplanes. Safety wire pliers are not necessary in your case, they just save you a small amount of time. A small set of vice grips will make it a little easier.
