Two of these Disco DFG-82\/IF Backgrinder spindles came in as a pair. The first spindle was in pretty rough shape. Prior to disassembly we pressurized the coolant circuit and found evidence of an internal coolant leak. Before the spindle even came apart though we had to Mfg. a special tool to remove the tool hub without damaging it or the spindle shaft. Once the spindle was dismantled we were able to verify the internal coolant leak and its origin. Several of the coolant plugs within the housing OD had failed allowing coolant to seep by and into the spindle. We tapped the ports and replaced all existing plugs with new stainless steel threaded plugs with sealant. After proving the new plugs held pressure, we rebuilt the spindle. Of course all bearings were reworked as needed and all other seals were replaced with new. It was then balanced at operating speed and performance tested. The spindles stator housing was painted with a Hi-Solid two part epoxy and the spindle was prepared for shipment. It looked and ran like new!<\/p>\n
