Hi Mike, I have spoken this morning to a gentleman who is a TORO repair specialist...He explained that you have done the hard part; (ie.) getting the clutch off without breaking it..(he said they often have to almost destroy it because of corrosion to get it off and they are $1000 to replace...ouch!!)
The upper pulley is a press fit that has a key built into it and should pull off with a gear puller once soaked with heaps of Penetrene and the lower part of the shaft cleaned up.
He said to do the following:
1. Open
http://www.toro.com/2. go to Home Owner Parts
3. When asked, enter your full Model Number and Serial Number of your machine (found under the seat of your Toro); this will take you to complete working drawings and give you the info you require.
Please let us know how you get on.
