Hi Idlehands,
I removed the same gear off of my 94 M900 and it was a real bitch. The shaft that the gear fits on is tapered and the gear has locked onto the shaft. There is also a keyway to keep it from rotating (like it ever will!). Here is what I did. I got the biggest puller I could fit and used an impact wrench. I put penetrant on the outside of the gear and used the impact wrench and tensioned the heck out of the puller. I then just let it sit overnight. I did this for about 3 days and it finally let go. Good luck. Also, be very careful to be out of the way of the gear. When mine finally let go it shot back and put a hole in the sheet rock in my garage wall!
