I would try scuffing it with some sand paper and use some motor cleaner to clean it. Are you very good at soldering.?
If not a good Weller 40 watt is what I use. Its best to tin the tabs on the motor first. Then tin the wire and apply to the tabs with the iron.

Try some resin core solder.

or clean the connections with solder flux then try again...

getting it very hot is key, also get a friend to help works to get the best solder connector, or perhaps a "third hand" type device to hold the wire steady, even small movements while solder is hardening cause weakness and often cause it to not properly stick. like previously said 60-40 is what your looking for, i accidentally bought some crap from sears don't use that home crap. good ol fashion poisonous lead works best and there are devices made for cleaning solder, solder wick or braid is like a coper wire sponge, also make a suction device. all can be had cheap at radio shack

a dremel with a sanding drum works well for scuffing and cleaning off.

Can you explain how you are trying to solder the wires? Maybe you are missing a step? As someone stated previously, you need to tin the wires going to the motor first. Also, a small amount of solder placed on the motor tabs before hand will help. Place the wire on the motor tab and melt them together....it has always worked for me.

Revolutions are not easy to solder. You MUST have a good iron... either one with a big fat tip, or one that is VERY hot, or better yet both fat and hot.

Ha ha... seriously. If you don't have a good iron it's a nightmare soldering these motors, because of the massive heatsink that you solder the wires to.

It's also very helpful to have some paste flux handy... that will make the solder "flow"... sizzle and stick.

And like others said... also important:
rosin core solder
tin the endbell... get the endbell hot and coated with fresh shiny solder

well it seems like you have the right slodering iron, i used to run the revolution motors and had the same problem sometimes. Like people are telling you, you really have to get the solder tabs hot in order for the wires to solder to them.

Are you shure the tip on your hakko are still good? I can always tell when the tip in my hakko goes bad, it starts taking forever to solder things it should do quickly and with no problem. It doesn't happen near as often now, but when I was racing electric every weekend I'd go through 2 or 3 tips a year. You may also want to check the ceramic heating element. It's rare for these to bun out, but it does happen.
