You need to solder them on.

Use your soldering gun to unsolder the wires and just resolder them back on with the new bushings.
It is quite annoying and some slight skill is required. (I am horrable at soldering)
Afterwards don't forget to break-in the new bushings.

thanks e2m...this is a total NOOOB maneuver on my part. I was ordering some blades and some other bs when I came across the silver brushes. I've heard all you guys talking about them and the performance increase you can get. However, the big NOOB part is that I don't know what the heck the brushes are really. I'm starting my research on the subject, here at rcu. But i'm not rippin my motors apart until i'm 100% sure about this. it was worth the $6 to have them in my kit, since I was buying other stuff. I remember that photo too. If any experts want to volunteer a little private tutoring, the technology is available these day with instant msgr's. I use yahoo and I do have a cam. thanks for the input...now off the search the forums.

When You get the brushes, it will be very self evident what they are and where they go. Unsolder from capacitor and motor lead first.

You can use your fingernail or small flat blade to pry them out from the can cap; starting at the bottom; gently pry upwards and it will pretty much fall out from there. Then, insert the new ones top first, then it will 'snap' in at the bottom of the upper can cap.

Use paste flux on the old joint and it will melt much faster and won't cook the solder joint too long as You will melt the plastic cap. You want to be on and off as fast as possible. Remember the wiring configuration red/black. Do it one at a time or mark a dash on the can for the neg. or something.
