Prevaintive Maintenance

The essence of Preventive maintenance lays in this 'Fourth step', hence need to be elaborated.

What do one do after identifying the Wear parts and estimate its lifecycle...

- Bring-out a list of 'critical components' considering HSE and production. Consider using FMEA.

- Establish the best 'condition monitoring technique' for these 'critical components'. Like: vibration monitoring, wear particle analysis, tomography etc.

- Establish the best 'monitoring interval' considering the life-cycle of these critical components.

- Establish a 'master chart' detailing: which equipment, which part, what interval, which monitoring technique. Follow regressively and fine tune on feedback from breakdown reports.

My first line of defence in maintance was the paper work on each machine organized and on a computer with dates of instalation of all motors and parts. Established wear and replacement limits.

I also has employees trained as helpers to inspect and do the daily grease and inspection of each line. Eventually I sent a few of them to school on the company dime for different things like electrical, machine, and computer control maintance.

The new comprtized viberation reporting systems are something I never got to work with but I would now if I were still out there.

Dear Friend,

There are good answers by every one. I will add a bit. Use statistical techniques to improve maintenance performance. Like: Pareto analysis, bar charts, cause & effect diagrams, etc. I have32 yrs experience in Equipment maintenance and I just love working as a maintenance manager (solving and preventing problems).

Implement Total Productive Maintenance (TPM). There are several books and guides available. A web search will give you a lot of information. Also, set up a data base with all the information about the equipment previously mentioned.
