I'm needing service manual for 1986/83 case 680ck. Hydralic pump specifically. Any help on how to take off and service I think the seals are gone. Thanks
Welcome to HEF, hakejackson ! All of the 680's are CK's. The serial number of the tractor is needed to determine which model you have. 680G, 680H, 680K and the list goes on.
I may have the service manual. But, I need the serial number of the tractor to know which model you have. There should be a tag on the side of the steering column with the serial number on it.
