Finally a way to remove and replace the alternator pulley without removing the alternator!
A while ago, I was talking with Fixumrich about how you should be able to remove the alt pulley in the vehicle if you had the right tool. We decided that it should be possible if you shorten the m10 tripple square and fasten a wrench to the end. Rich wound up doing it a while back, but just used a grinder to make a rough prototype and it worked great. Today I made a more finalized (clean) version on my lathe and used it as well. Basically I got a replacement m10 tripple from the Snap-On truck. It starts out made from a 11mm hex shaft that rounds out and ends with the m10 tripple. I measured just how much of the hex shaft I'd have to turn, and cut it so that there is just a bit of hex left when the tool is installed in the alt pulley.
With this setup, you slide the two tools at once up and into the alternator pulley. Then using 17mm and 11mm box wrenches, break the pulley loose. Remove the tools after breaking loose othewise the frame rail will interfere with removal. Spin the pully off by hand and spin on the new pulley, tightening the same way.
Here are some pics of my setup. I've emailed Chuck at Metalnerd... Who knows, maybe he'll decide to make some.
I hate to toot my own horn, but this is such a huge timesaver.
