3 Greasing Practices, Chiller Techs Opinion

[@j.b3377]

Thanks for the video…. Appreciate going back to clarify basic duties. Perfecting these basic duties will build a great mechanic. For such a small task it has many complexities to it… I would love to hear your opinion on belt tensioning practices for a fan or compressor.

Funny enough....bearing manufacturers will tell you....its better to under grease than over grease bearings. There is a information available on how much to use based on how many hours the motor has been in operation. I like to look at the run hours on the VFD. You can reset it after each PM you grease the motor. If your grease is turning a blackish color....that could be a sign of shaft voltage from the VFD.

I went to a B&G class in 2016 where they stated 2014 and up the EM grease(exclusively) or Lithium Complex is the only 2 types of grease they wanted us to use I have maintained that since with no issue
