Cone or clutch??? How to identify?
A cone type unit has only 2 "windows" to look inside it and you can see some large springs and it also only has 1 cross pin with 2 spider gears 180* apart. A clutch type has 8 window's and no springs at all and 4 cross pins and 4 spider gears every 90* apart (much heavier duty). I attached a couple pics of cutaways of each. Sorry I don't have any pics of assembled units but if you look in the parts for sale section SGBarracuda has a picture of a clutch type that he has for sale.
