The idea of preventive maintenance (PM) for parts on the shelf is one area that some people may think is unnecessary. That can be a false economy.
At IBT Industrial Maintenance Technologies (IMT), we have heard about large electrical motors that were stored for several months in an end user’s warehouse and not given any attention. In one case, the company brought the motors several months ahead of when they were to be needed – they were at the end of a long supply line. Their thinking was that this would assure availability. However, after three months of shipping transit and months in the warehouse without attention, potential problems arose.
It’s a good idea to do a little PM when you must warehouse components with rotating elements, such as gearboxes, motors, etc. Train maintenance people to carry out routine procedures, for example: rotate the motor shaft from time to time while it’s on the shelf to greatly reduce the chance of false brinelling.
In the case of the motors on the shelf waiting for installation, when they were installed and started up, there were problems. Bearings on the drive end and non-drive end heated up. Vibration signatures rose exponentially overnight, indicating bearing faults. The company had a large amount of downtime because of motor bearing failure.
The PM on the shelf process is neither expensive nor time consuming. The problems that may result from not doing the PM are both: expensive and time consuming. IBT IMT helps you avert these risks.
Our technicians can help you set up PM procedures and train your people as to what to do, when and how to do it, and how to document their work. We also provide turnkey services to handle the whole thing for you.
Essentially you have three choices and the option of doing nothing is the wrong one, especially when IBT IMT will help you make the most of your investment. Let IMT know if we can help you weigh your options.
