"why." "Why are we engaging in this?" "Why is it important to the organization?" Answering these questions is essential to any change management process. I've intentionally saved the "how" for last. In nearly every class I teach, I ask the following question: "How difficult is it to operate a grease gun?" Although the mechanics of this task are quite simple, are you aware of how much pressure a grease gun can generate? Do you know how much pressure it takes to blow a lip seal or push shields and seals into the element on a bearing? Are you able to look at an oil analysis report and tell whether the sample is the correct fluid just from the test data? Can you identify the chemical compounds that make up certain additives? How many of your lube techs can answer these questions? I'm constantly amazed at how lubrica- tion technicians are consistently at the bottom end of the scale in a maintenance organization. Properly trained and equipped lube techs are the eyes and ears of a maintenance group. They are the foundation of maintenance. It is not uncommon for a fully trained lube team to generate 70-80 percent of the work orders. They are the ones who conduct most of the inspections and identify the majority of issues. However, to be effective, these individuals must be trained in the appro- priate inspection techniques. Let's go back to the question of how difficult it is to operate a grease gun. How does it feel when a seal blows out because of too much grease at too high a pressure? Explaining this is like trying to describe the color red to a blind person. If you haven't felt it, it is difficult to understand. Many aspects of lubrication are like this. Frequently, classroom training is inade- quate for the task. A lot of people learn best by doing. Although much, if not all, of the "who," "what," "when," "where" and "why" of lubrication can be taught in the class- room, the "how" is best demonstrated in the field using the show-and-tell method. Instructors can "tell" you how, but the "show" requires you to be at the machine installing a breather, sight glass, quick connect, etc. Filling the Knowledge Gap The average age of skilled workers in the United States is reported to be between 53-57 years old. As these individuals retire, who is going to replace them? How will you fill the knowledge gap that exists at your plant? One answer is to have well-written and detailed procedures to ensure that technicians can perform the job regardless of how long they have held the position. Procedures can provide the basis for your training program, but sadly most are quite primitive with instructions such as: "Give machine A four shots of grease and machine B three shots of grease." Effective proce- dures define what a shot of grease is so you know precisely what quantity of lubricant should be put in the bearing or seal. Many lube techs and program managers will require hands-on training for the "how" of lubrication. This should not be provided from a theoretical standpoint but through actual mentoring and guiding. During training, technicians should perform lubrication tasks under the guid- ance of a consultant, who then evaluates proficiency. At the end of the training, your lube team should be able to implement and execute your lubrication program just as if you had consultants onsite doing the jobs themselves. Remember, even if you have invested large amounts of resources in your program, you may still need to invest in training for your team members in order for them to execute your procedures properly. By applying these strategies, you can develop a training program that will address, mitigate and possibly eliminate the most destructive contaminant in your plant.
