Just found this on one of our reach trucks during a PM. The dings in the cylinder from the chain were deep enough that they were pulling quite a bit of oil past the wiper. As Raymond cylinders are a pain in the butt to re-seal, I decided to repair. Block the carriage and disconnect the chain, leaving the damaged area visible. Circle emry cloth around the cylinder and sanded the high parts of the divets down. Used JB weld putty to fill in the low spots. Waited one hour and sanded smooth. No more leak and the new operator learned something.
