I got a 670 that has a stuborn primary on the end of it and it wont let go. I have the correct puller, wacked it with a BFH under tension, tried teflon on the threads and powersteering fluid inbetween the crank and puller. im about ready to break out the heat but i dont know if that'd be a good thing or not. Any tips guys? Ive never had one this dang stuborn.
