How big a task is it to replace the pto clutch in an early model 3020 syncro-range diesel? I am sure my clutch fingers ends are burnt off from what I think is a bad bearing that locked up. The pto just quit working and looking in from the bottom cover I can see the fingers do not touch the pto drive any longer and there is no pressure to the lever. I don't have a concern about splitting the tractor but is there special tools needed for replacing the bearing and clutch fingers? Thanks in advance to everyone for your help and advice. If it is not what you would consider a large job to accomplish I would like to save the $1000 that the dealer told me it would be to open it up and then fix if it is just the bearing and fingers in addition to the cost of the parts. Thanks to all as I read the posts here often and everyone has really helped me save some money as I try to do what I can myself.
