The Link Belt 2800 in the early 90's was about the time Case and Sumutoma bought into them. The Case machine were 9010,9020,9030,9040,9050and 9060. I think the 9040 is the same as the 2800. We sold quite a few 9040s and 9030 size machines. They were a very good machine. Only problem is they had a number of cylinder changes and parts are hard to get. The seals are no problems, if not from Linkbelt or Case, Hercules Seals will have them. It's a problem if the gland, Rod or barrel is damaged.They are hard to find and expensive to manufacture at a machine shop. Check with your linkbelt dealer about parts availability. If it is a 1991 or newer the Case 90 series were exactly the same machine except the motor. They may have some parts .
