I had a customer the other day inquire about TwinDisc clutches he's trying to buy parts for. This is out of my realm of the usual say to day stuff I sell but I would like to try to help him because he's a good customer. This particular clutch no longer has anything to ID it so I don't have a part number. I tried looking on TD's website but there isn't any exploded diagrams for me to figure out what I need. Does anyone here mess with these? I'd like to educate myself on them a bit before I just refer him to someone else.
