Those working in the field of maintenance know how important it is to the success of any organization to maximize reliability and minimize or eliminate unscheduled downtime. This can be a daunting task and often requires professional collaboration, a change in organizational culture, and the willingness and ability to make decisions that are not always popular.
Lubrication Engineers (LE) is no different than any other manufacturing facility in the world. It can only make a profit if it is producing quality product and shipping it to customers in a timely fashion. If the facility experiences unscheduled downtime with its production equipment, it causes a ripple effect throughout the entire operation. When this happens, the organization seeks to learn from it and get better to minimize the risk of it occurring again.
LE manufactures its own high-performance industrial and automotive lubricants in its 200,000-square-foot manufacturing and warehouse facility. Its products are distributed and used by companies all over the world (Figure 1). As a batch process manufacturer - as opposed to a continuous process manufacturer - LE is able to give each product an intensive care approach during the cooking and blending steps. It formulates its products to meet the needs of the application and not just to meet minimum specifications.
Figure 1: LE distributes products to customers all over the world out of its warehouses in Wichita, Kan., Knoxville, Tenn., and Las Vegas, Nev.
After the finished product is approved by quality control, the product handling department fills containers ranging in sizes from pint bottles to tanker trucks. Product is stored in three warehouses across the United States, which helps lessen the delivery times to customers in various regions.
All this may sound good, but LE is never satisfied with the status quo. The company works continually to maintain or improve mechanical uptime in order to provide quality product and reliable service to its customers. Seven years ago, LE had some challenges to overcome. The biggest challenge was the need to change the reliability culture in the entire facility. While LE was already very good at helping its customers improve lubrication reliability and mechanical uptime, the company knew it could do better in its own facility. The organization needed to walk the walk, not just talk the talk.
LE needed to focus on managing its assets at a higher level than ever before. The company initiated plant-wide meetings to discuss reliability topics. Discussions focused on reliability in terms of how it relates to its employees, as well as its customers. LE determined that it could do better in its reliability efforts and save money by doing so.
The beginning of a reliability journey can seem overwhelming, but that is why it is so important to be patient and take one step at a time. Although it would seem easy for a company like LE to get started because it already partners with reliability-minded product and service providers, its reliability journey still sputtered, at best, in the early stages, even with this built-in advantage.
It was imperative that senior management recognized that good lubrication practices would protect assets and keep them generating products and profits, positively affecting the bottom line. LE also needed its leaders to place equal importance on both human and mechanical assets.
Education & Training
LE chose to spend money on its people to get them the training they needed. The maintenance team and senior management attended maintenance reliability conferences and as many training opportunities as possible. Many were able to earn certifications, including Machinery Lubrication Technician Level I (MLT), Oil Monitoring Analyst Level I (OMA) and Certified Lubrication Specialist (CLS), which further increased their confidence and ownership of the process (Figure 2). They then began implementing what they learned into their operations.
Figure 2: Continuing education is a priority, as evident by the many LE employees with advanced certifications.
One of the first changes made was installing desiccant breathers and sight glasses on many of the assets (Figure 3). Top-down support was crucial for this investment to happen. It was understood and agreed upon that increasing the reliability of each asset would lower the total cost of ownership. LE later incorporated other reliability products, including automatic lubricators and filtration devices.

As the workforce's knowledge level increased and reliability improved due to the small changes put in place, improvements began to accelerate. LE began looking into a computerized maintenance management system (CMMS) because, up to this point, maintenance reliability technicians were working from computer-generated asset cards to do lubrication activities. Maintaining this archaic system was not easy.
During its review of several CMMS packages, LE realized that a CMMS would be more time-consuming to implement than a simple computerized lube route system. At the time, the main goal was to quickly get a better handle on lubrication reliability practices, however, many of the CMMS packages reviewed did not incorporate lubrication, or their lubrication components would have been cumbersome to implement. After many discussions, LE came to the conclusion that adopting a CMMS system did not make sense at that time for its five person, one shift maintenance department. Having made this decision, LE was able to proceed more rapidly with the rest of its journey.
LE's mechanical assets include 177 gearboxes and gear reducers, 119 electric motors, 51 pumps and 21 stirring vessels, as well as compressors and additional miscellaneous equipment. The entire facility was surveyed and each lubrication point on each asset was identified. This helped the facility visualize the amount and type of equipment it was performing maintenance on and gave it a blueprint to start managing the equipment more efficiently. This is a critical step in the process and should not be skipped.
Lubricants are the lifeblood of mechanical assets throughout any facility. LE regards them as assets, not consumables. In fact, LE looks at lubricants as its number one asset. Just like any other asset, lubricants need to be maintained properly and used properly for specific applications. A well-equipped lube room will protect these fluid assets so you can sleep at night.
LE purchased a new lubrication storage system and created a dedicated lube room (Figure 4). This made it evident to all employees that the company was serious about reliability. The maintenance team took ownership of this new lube room and storage system, and they are very proud of it.
Figure 4: LE’s new lubrication system keeps lubricants clean and dry with filtration into and out of each tank, and everything organized and color-coded for a smarter, more efficient process
This created momentum in the lubrication reliability journey, which became increasingly evident as the maintenance team began to think of more ways to improve machine uptime.
All lube points were tagged according to product number and color-coding that matched the storage system tanks was implemented. This helped make lubrication a smarter, more streamlined process for the team and it raised the knowledge level of each team member.
Lube Route Software
After a search of available software solutions, LE purchased lubrication reliability software to manage all its lube tasks. The quick turnover to this system enabled LE to keep its mechanical assets running and minimize downtime. With the software, LE was able to assign lubrication routes and schedules to team members who took ownership of the process to ensure "their" equipment was maintained properly.
The software significantly improved LE's ability to manage the lubrication of its mechanical assets and helped the facility organize its approach to handling maintenance activity.
By implementing all these steps on its reliability journey, LE has seen a major reduction in the cost of equipment repairs and maintenance. From 2006 to 2008, LE documented an annual average expenditure of $243,000. In 2009, the first full year after lubrication reliability changes, this annual number dropped dramatically to $83,000. LE spent an average of $76,000 annually in the five years since the program was implemented on repairs and maintenance of equipment (Figure 5).
Figure 5: In five full years after implementation of its lubrication reliability program, LE’s average annual expenditures on repairs and maintenance dropped 68 percent, from $243,000 to $76,000
Using condition-based monitoring and oil analysis, LE also drastically decreased its oil usage. From 2008 to 2013, annual lubricant usage dropped from 449 gallons to 67 gallons, for a savings of more than $11,000.
Reducing lube change-outs, as well as repair and maintenance tasks, contributed to significant labor savings. In 2008, 672 hours of labor were dedicated to maintenance and repair tasks; in 2013, that dropped to 120, for a savings of nearly $10,000 (Figure 6).
Figure 6: From 2008 to 2013, LE reduced lubricant-related labor hours by 82 percent and lubricant usage by 85 percent, which added another $21,000 in savings
Looking back, the main drivers that helped LE on this journey were:
- Supportive top-down leadership;
- Willingness to invest equally in both people and mechanical assets;
- Detailed plan of attack;
- Patience (organizational stamina);
- Quantification of results.

With similar drivers in place, your organization can achieve the same positive results. The most important thing to do is take that first step and get started. Soon, you will be on your way to finding the hidden plant within your facility.
