Hello Everyone. I've owned a Digit 198T for 20 years and its ability has become weaker. Main pump transmission part # 40-03-7500 must have a rebuild kit somewhere. Is there another part name or part number for this pump? I saw someone posted that a John Deere 300's pump parts work with some mods. Does anyone know any updated info or have personal experience on rebuilding this pump? Any help is greatly appreciated.
