Was wondering if anyone here knew of a source for a service/repair manual for a LeRoi Dresser 2 stage air compressor, model no. 400, ser. no. 453X11947. I had one but can't find it now and haven't been able to locate one with an internet search. The unit has a rod starting to knock and I want to rebuild it and found a kit. But I want that manual before I start. Thanks to all for your time and any help.
