Chapter 19, Problem 1RQ
Why is it necessary to keep lubrication records for motors?
Expert Solution & Answer
To determine
The necessity for keeping lubrication records for motors.
Explanation of Solution
Some electric motors contain sleeve bearings which require oiling periodically. The motors which have ball or roller bearings are lubricated with grease. The motors which contain sealed bearings do not require lubrication.
In order to maintain proper lubrication from time to time, a lubrication record is required to be prepared. A lubrication record is the best method of ensuring that motors are neither overlubricated nor never lubricated.

- What is a torque diagram?arrow_forwardA technician is working on a 2005 BMW 7 series.. The compressor is running all the time and the air is cold. The tech unplugs the wiring harness leading to the compressor, but it stays running. The technician recommends a new compressor as he suspects the clutch has melted. What is likely happening here? nothing. This compressor doesn’t have a clutch, only a pulley the clutch has melted due to a slipping belt only the hub needs replacement, the pulley is fine the compressor must be seized internally for this to happenarrow_forwardQuestion NO:1 Answers these questions in detail with few explanation of all. a.
