Flat or split lock washers under the nylock nuts? Does it matter?

The washer and nylock nut are used to secure #113.

Thnaks guys!
 
Flat on mine Skip under Nyloc.

Cheers,
Tush
 
Thanks guys. I put flat on.

But that raises a question - for me anyway - why not use a split lock washer? Is there a down side?

Again, I used the correct flat ones but I'm looking to learn why not the split one?

Both are intended to keep the nut from backing off so having both a lock washer and nyloc nut may be a bit much. Since these are english threads and in the english language a double negative equals a positive, running lock washers with nyloc ensures that the nut will fall off. :nonono:
 
Another reason, split lockwashers will damage the spring pan. Flat washers both protect it from damage (as the nuts are torqued against it), and spread the load out, making the assembly stronger.

LOL
 
Another reason not to use split lock washers is they really aren't that dependable. They work some times, but not always. At a sales meeting years ago, we were told that split locks are pretty much useless, but not to let this information to keep us from selling them. They are "cheap" insurance. There are good functioning lock washers manufactured, but they aren't available at the local hardware stores.
Nyloc nuts work well in non vibration areas, but don't reuse them. All Steel "C" lock nuts are the best, especially with drive shafts.
 
If your threads are media blasted wire brush them if possible and use a light lubricant for correct torque, dry torque give them a few extra pounds, in theory a regular nut works because the torque action stretches the bolt to hold the nut tight, but nyloc nuts do a better job and look nicer.
