50,000 Hour Off-Highway Diesel Engine Rebuilds: They Are Possible!

By Mark Barnes

From dozers to graders and loaders to haul trucks, diesel engines are everywhere. For companies who rely on diesel power to make their living, there’s no greater emphasis than diesel engine reliability. But when it comes to diesel engines, they also have some of the shortest life expectancies.

A New Era: Wear Particle Analysis/ Ferrography

By Raymond J. Dalley

Wear particle analysis, or ferrography, is a technique that is growing everyday. With industrial needs for reliability and higher productivity to compete in the world market, techniques such as wear particle analysis become vital in making diagnostic and specific recommendations regarding potential machine problems.

A Proven Electric Motor Regreasing Program

By Jerry S. Honeycutt, Tennessee Valley Authority

One of the most asked questions of grease lubricated motors is, what is the correct interval to regrease the bearings? This is usually followed by two questions, 1) how much grease should be added? and 2) what is the correct method for grease addition?

Audit, Develop and Implement

by Paul Dufresne

Completing an Audit and Implementing Changes to Boost Lubrication Program Performance

In 2009, Trico Services was contracted to complete an equipment lubrication audit of a large mill in the southeast that produces liner and corrugated material for containers. This audit was for roughly 2500 pieces of rotating equipment. Upon completion of the audit, Trico was to take the lubrication recommendations and input this data into the MAINTelligence software platform that the facility uses using to manage their plant lubrication programs.

Automatic Lubrication Systems - Don’t Work!?!

By: David Piangerelli

Companies seeking ways to gain operational efficiency and increase reliability often turn to technology. Increasing productivity with reducing operating costs has become a mandate for managers. Maintenance plays an important role in increasing equipment reliability through condition monitoring of critical assets, using tools such as oil analysis, vibration analysis, thermography, etc. Each concept or tool must often be sold to the management team, who is looking for a return on the investment.

Best Practices Lubrication for Universal Driveshaft

by Paul Dufresne, CLS, CMRP, CPMM, Trico

In tough working environments, machine reliability can be difficult to maintain - especially when contaminants threaten bearings and components. One such application is the universal driveshaft - a component that faces neglect due the extreme conditions and locations where they are used.

Building A Lubrication Program - By Using the Five Rights, You Won’t Go Wrong

by Ray Thibault, CLS, OMA I & II

This article will examine the use of the five rights of lubrication - which are Right Type, Right Quality, Right Amount, Right Place and Right Time - all of which are important in the development of a highly effective lubrication program. Many companies fail to realize the importance of lubrication and the application of these five basic concepts to achieve world class machinery reliability. Each will be examined in detail, along with a summary of best practices, including procedures in the selection of the optimal lubricant supplier.

 

Clearing the Confusion

Simple is always better. And solutions really don't come any simpler than this one.

Imagine eliminating virtually any chance of cross contamination in all of your grease applications. The solution is as simple as switching the type of grease gun you use. 

That's it.

Contamination Control Can Reduce Costs

Today's mining industry is facing a new set of challenges. Commodity price projections for the future remain uncertain, global demand remains high and there is a global labor shortage. While the mining industry remains highly competitive and essential to continued global economic growth, mining companies continue to search for ways to sustain growth and profitability.

Creating A Sustainable Operator Driven Lubrication Program

The position of 'oiler' or 'lubricator' has been all but eliminated in most companies. There has been a number of responses to this change however one of the most effective is to create a documented and well defined Operation Driven Lubrication program.

This presentation provides details and case studies of successful Operator Driven Lubrication programs (ODR) and how it can fit into a more comprehensive Performance Management Program that breaks down silos and aligns people toward the aim of the organization.

Determining Grease Lubrication Intervals and Amounts

In any grease lubrication program the hardest thing next to determining the correct grease is determining the frequency and amounts of grease to use. Most original equipment manufacturers supply a simplified chart with appropriate greases, frequency based on general conditions and speeds, and an amount of grease based on the bearing size. Equipment OEMs are a good place to start for this information, but from even one motor manufacturer to another the amount, method and interval can be drastically different for the same type of motor. What about equipment that falls outside the norm or if there is not adequate information from the OEM? The good news is that there are a few devices that when put together can help us take the guess work out of the quantity and timing of greasing tasks.

Effective Guidelines for Implementing a Well-Engineered Lubrication Program

by Kevan Slater, CLS

A global recession, combined with intense global competition, is forcing many companies to review and search for a "proven" method of reducing their overall maintenance costs while increasing the reliability of their aging equipment. Despite the continuous preaching of the benefits of implementing an effective lubrication program, many organizations still lack the formal direction and understanding required. This article will provide a proven methodology and direction to obtain the benefits of a Well-Engineered Lubrication Program.

 

Electric Motor Bearing Greasing Basics

One of the most important components of any electro-mechanical maintenance program is the lubrication of bearings. Yet, this vital aspect of preventive maintenance remains one of the least understood functions of maintenance. There is constant debate concerning whether a bearing should be ‘flushed,' a limited amount of grease added, how often or if the motor should be operating or tagged-out. Many motor manufactures outline the preferred, and safest, method for lubricating electric motor bearings. There are specific physical properties for this process in the motor bearing housing and in order to protect motor windings from contamination.

Eliminating Lubricant Cross-Contamination With Manufacturing Improvement Principles

Trigg Minnick

With the growth in base oil types and additive combinations that we have seen in the past couple of decades, the possible combinations of final blended lubricants has grown exponentially. While this can allow lubrication programs to hone in on the most suitable lubricant for an application, it also means we can have 15 to 20 different lubricants to manage in one facility. It's no wonder that issues of cross-contamination of lubricants are prevalent in many plants today.
