whats involved in the changing of the lower gear. procudure or any special tools involved. thanks.

Back out the 2 allen head bolts that hold the gear on the cone, run 1 of the bolts in the 3rd hole in the cone until it bottoms out, then get another 1/4-1/2 turn on it. That should push the gear off of the cone, if not, tap it with a hammer & turn the screw some more. Repeat until the gear slips off the back side of the cone toward the shaft housing. Next, take a wooden shim & slip it into the slit on the cone just enough to loosen it from the shaft. Remove cone & gear, replace everything back onto shaft.

Sent from my Droid because I'm trying to be as cool as you someday.

Be extra carefull when prying that cone off. I cracked mine the first time I did it. i have heard it will still work craked but I orderd a new one and replaced the seal in it right away just to be on the safe side. Like camo said use a wood dhim I found out a flat head screw driver was a little much. On the plus side it comes off way easier in 2 pieces

They will work just fine with a cracked Taper lock bushing once they are aligned and pulled back into the pulley the friction bond will clamp to the shaft and to the the pulley.

thanks for the good info.
