It's not that you need you to use silicone to install a crank seal it's that you need a small amount of lubrication,so it doesn't burn and deform the neoprene seal lip on start-up. This is the mistake people make When you add silicone and the repair takes a certain amount of time before starting the engine, the silicone has dried and cured this leads to the problem, when you start up the engine the dried cured silicone it's torn and running all around the seal lip, this creates the spot for it to leak a bit, because of silicone rubber now all under the neoprene seal lip. Now, this is not a tight seal anymore. this is why I would not use silicone to install any seal that is going to be rotated on, I just use lubricant. There are plenty of brands of rubber lubricants out there that you can use to install a crank seal
I had a tub of petroleum jelly in my toolbox just for seals and o-rings. Just a small film of any lubricant will work though. Also if it calls for a specific installer for the seal but or barrow it. Otherwise you will be doing the job again.
First of all that's a nice seal installer. Always put a little grease or oil on the inner rubber of the seal. If your worried about the seal not staying in place, lock tight on the outside will work great. Careful not to get any on the inside of the seal.

Assembly lube, little white lithium grease. Silicone spray just a little.
Cummins says soapy water
Assembly lube
White assembly lube, not a lot just wet the surface with it
A little Petroleum jelly works for me
It may be a little cocked. Turn the crank half a turn and push again. Worked for me on a Caterpillar.
Trans fluid . It wont distort the rubber, and stays wet ? Just a thought .
