I've read that some of the black sinks are machined really tight on the tolerences...
I've heard guys say if you get your motor ready for it - then use a hair dryer or heat gun to get the heat sink hot so it expands a little they will drop right on. Then when they cool they get a really good heat transfer by being extra tight...

Indeed, you just have to be very careful with it, I have a blue one that was also VERY hard to slide into place(got Charlie to help me with it at the Novak Race & it took both of us to get it into place without damaging anything). One thing we did was use the purple ring(that the heat sink replaces) as a guide, placed over the heat sink & then apply the pressure to the ring. Seemed to do the trick for me(& the heat sink is DEFINITELY worth the effort, I see mine get as much as 20-25 degrees hotter than the rest of the motor, so it's definitely pulling heat out).....

Hold both the heatsink and can with pliers... get the heatsink really hot (melt the sticker off) and also warm up the can itself pretty good... then slide the heatsink on really fast... if you can get it on far enough then you can put the endbell back on and crank it down with the 3 long screws

a heat gun is your friend.

I would be careful using the endcap and screws to get the heatsink in place. I snapped of screws into the body of two motors trying it this way. I now have two novak paper weights If you get it all hot enough you shouldn't need that kind of force.
