Rod Bolt Nuts

I am rebuilding the engine on a 48 8N converted to 12 volts.
The nuts holding the bearing caps on the rods have fine slots cut in them, are turned down a little on the diameter, and have a little notch cut on the turned down portion. There were no clips, locks etc on them when I took them off.
Is there suposed to be some kind of lock on them ?
Are they reusable or should they be replaced ?
If they are reusable, should the turned down portion be squeezed a little before use ?
Would it be a good idea to use some medium strength locktite on them during reassembly ?
Thank You for any help or suggestions.
 
I aways buy new nuts for the rod bearing caps when doing a rebuild. nnalert has them and this site may also sell them. I have not used locktite on these nuts but it would not be a bad idea. I do not use any kind of lock nut with the new type bear cap nuts.
 

Per the "High Dollar" machine shop that rebuilt a motor for me once, you want to rely on the "stretch" that you put on the bolt at specified proper torque, to hold the nut on. In order to achieve the proper stretch the fasteners need to have not been previously over stretched. So if someone before you decided to go 15% over on torque or if he oiled them and the spec was for dry or he put them together rusty and you have them clean, etc. your values can be off.
