I appreciate every one of your responses and suggestions.
Matt, your last comment gives me the "courage" to persevere without the "proper" tools ;o) Tapered shaft couplings that haven't been apart for 25 years - been there - used a special puller and some heat.
If this is a straight shaft, (need to look at the pictures in my manual, I guess) some penetrant, wacks on the the hub, and a hair dryer for some heat, might be worth another go.
Legendre, you're pretty close to where I live so if there is a need to use your pullers I'll let you know for sure - thank you.
ok - I will say this: of the various technical type forums I've tried on the web this group is tops
Thanks again - i'll let ya know how it goes.
