Just picked up a mint condition home use only commercial pedestal version of this game a couple weeks ago. Awesome deal and only 83 games played on it since they bought it brand new years ago. Not a spec of dust inside and I know they didnt clean it out because they didnt have the keys. Anyway, the trackball was a bit stiff when I got it, its loosened up significantly since but still pulls to the left. I would like to clean/lube the rollers or replace the trackball unit completely, but I cant find any info on how to access the track ball mech. do you happen to have any info on accessing the trackball unit? Do you have to remove the entire table top or does the metal trim come off somehow?

Thanks for any help!
