Got a Marathon 250 SC that needs a new cylinder, this the right one for that machine?

Question by: Rick J on Nov 11, 2025, 12:27 PM

this cylinder is built specifically for the Marathon Compactor 250 SC. It carries a 4-inch bore with a 2.5-inch rod and a stroke length of 31.5 inches, so it's a direct-fit replacement for that unit. The part number is CU4031-1037, and it also cross-references under several alternate numbers including C4031-1037, 1555339, and the RJ-250 CYLINDER designation, which lines up with the RJ 250 SC self-contained compactor. If your machine matches that model, you're looking at the right part.

Is this cylinder a direct replacement for the one on my Marathon RJ-250 compactor? Seems like the part numbers match up.

Question by: Shawn S on Jun 29, 2025, 8:16 PM

Yes, this cylinder is designed as a direct replacement for the Marathon 250 SC compactor, and the listed alternate part numbers (like RJ-250 CYLINDER and C4031-1037) confirm compatibility.
