Roots Blower Help Line: Ram X Repair

Here we have some recent repairs to a 770 RAM X.

A larger amp draw and trip outs from the motor indicated that the blower was having a problem. Once the blower was taken apart, R&M service technicians found a bad bearing had overheated and the inner bearing race began to fuse to the drive shaft. Because of the bad bearing the impeller end was grinding on the headplate and high friction, heat, and pressure caused detonation and deformation. These problems were probably caused by insufficient oil maintenance. We urge our customers to set up a proper maintenance schedule for oil, checking air filters, and monitoring instruments.
