Ok, now just remove the four bolts from the main gear. Impact helps as everything wants to turn. Put the gear with bearing into a freezer.

I needed to use the three jaw puller to slide the bearing off the shaft with the small gear...it comes off with little pressure, but wouldn't come off without help.

Install the large gear, line up the hole in the gear with the hole in the hub below...you will need this to put a rod/screw driver into in order to torque the bolts.
