I did a search already and didn't come up with much. I snapped a Birfield last weekend while backing up a gulley. It snapped the the last couple of inches off of the outer shaft. The cage is still intact and I can't separate it from the inner axle for the life of me. Tried putting it in a vise and wailing on a drift placed against the cage of the birf with a 8lb sledge and I also tried the pipe trick where you drop it into a pipe which "supposedly" will separate the birf. No luck and I'm running out of ideas. Any hints or advise about getting this damn thing apart (other than swapping in a D60)???

I have had good luck with the pipe method but you don't just drop the axle into the pipe. Heres how it works. Get a piece of 1 1/2" pipe that is about 6" longer than the long side inner axle. Stuff a rag in one end to keep the axle from slamming into the floor. With the rag end down slide the axle into the pipe. Now, with one hand on the pipe and the other on the birf, raise the whole thing over your head and SLAM it down hard. If it doesn't come apart the first time SLAM it again. One or two times will usually do it. If not, go eat a bowl of Wheaties and try again.

What Dan said. Works every time.

I just use a big F'ing hammer. Haven't tried the pipe thingy tho.

Pipe method works VERY VERY good. I even carry the piece of pipe with me for quick removal of a broken birfield on the trail. :D

I still use the pipe on mine, even with the mar-tac. VERY FAST REMOVAL!! Ping, done!! :D:D:D

I was over at Bobby Longs house a couple weeks ago to get my super birfields and this is how he separated them for me (nice guy to do this for me).
Put the axle shaft on the floor, stand on the inner axle and hit the birfield with a sledge hammer. One hit and it was off.
