Recently, I provided training for a location that had vertical mounted electric motors driving pumps that were one or more floors below them. In this case, these pumps were driven with Cardan Shafts, however they did not have the typical 5-to-15-degree angles (between the motor & pump shafts and the drive shaft) recommended for lubrication…

A colleague and client of ours called, in a bit of a quandary. “Ever seen anything like this?” he asked. I had to answer “No, I have not”. This is a C-face motor. It is typically mounted to a C-face flange, which connects to a vertically oriented pump. But in this case, the C-face motor…

This month marks my 41st year of being involved in industrial maintenance. Early on during my apprenticeship in a machine shop, as an outside machinist, I thought living long enough to know everything was not going to be possible. Even now I am reminded of this from time to time. I am also reminded that…

Many modern laser alignment systems include inclinometers that aid in the alignment process. Inclinometers, however, don’t work on vertically oriented machines. These include vertical “C” faced machines as well as vertical machines with feet. This meant that vertical machines required a 180-degree swing for accurate measurements and sensors were positioned the old-fashioned way by aligning…

The inclinometers in a laser alignment system work against gravity in the horizontal plane for a typical horizontal shaft alignment. When performing a vertical shaft alignment, the process will be different. Here is the process for aligning a vertically-mounted C-faced motor as shown on a vertical alignment demonstrator: Mount the sensors across the coupling. Special…
