Go to one of the replacement parts websites, like www.ereplacementparts.com
and look at the exploded parts diagram for your router. It should give you a good idea of the spring position in the assembly. Even a different type number should be close enough for you to see this.
Not sure why, but the www.ereplacementparts
website was down when I tried to access it. I wanted to provide a link direct to the web page for your router. I hope it's just a computer glitch because I buy most of my tool repair needs from them.
