    Ingersoll Rand sp56

    Hey all. Does anyone have any info/service manual for an IR SP56 smooth drum roller? Have one here that will drive well in both directions but no vibration. Sounds like the pump and engine loads up when you pull the vibe lever but nothing happens. Theres no test ports on pumps and motors Cheers
