LUBRICATION STRATEGIES Win the War with 'Lubrication by Design' Ken Bannister MEch Eng (UK) CMRP, MLE Contributing Editor Use aviation-style checklists to eliminate ambiguity and errors in your lubrication-maintenance procedures. ARGUABLY, THE MOST USED and abused instruction in the field of practical lubrication is "lubricate as necessary." The origin of that advice is often attributed to the OEM's (original equipment manufacturer's) machine operation and maintenance manual. OEMs typically prefer to use subjective language when outlining a maintenance approach in their manuals. As a consequence, they rarely provide accurate lubrication instructions based on the ambient condition factors found in the end-user's working environment. This is especially true when the OEM sells its equipment globally through third-party agencies and retains little control-or understanding-of how and where that equipment is used. The level of subjectivity is further amplified when an unsuspecting and/or unenlightened maintenance-department person follows, without question, the unaltered written instructions. A key component in reliability and performance improvement-with regard to maintenance personnel and machines-is consistency of effort. This type of consistency is afforded through an understanding in two major areas: S the impact that a current operating environment has on machinery requirements S who, exactly, performs lubrication tasks. The highest level of reliability possible with any machine is primarily achieved as a result of the simplest of maintenance observations and tasks, based on the equipment's weakest links. A machine's weak links typically present themselves in two formats: consumables and adjustables. Often thought of as "nuisance" or "pain" points, weak links are instantly identifiable systems or components of an equipment system that require regular or constant replacement or modification. Lubrication falls into both of these categories. Recognizing your work environment Lubricants are considered consumables because of their propensity to leak out of a closed environment or deteriorate in service, thus requiring replenishment or full replacement. A machine's working environment can dictate how quickly the lubricant will deteriorate. For example, a bearing operating in an extreme wet, damp, hot, or dirty environment, 36 | MAINTENANCE TECHNOLOGY The Sample Gearbox-Lubrication Checklist in the table on p. 37 points to Hi-Lo fill indicators that help personnel make simple, yet correct, Go/No-Go decisions when checking lubricant reservoirs.

Lubrication-delivery systems also require monitoring to determine application requirements and schedule adjustments based on changing needs. For example, using a manual greasing approach in bearing lubrication will require a change in PM (preventive maintenance) frequency when moving from a single-shift to double-shift operation. Similarly, in changing to an automated lubricant-delivery system, note that the lubricant reservoir will likely require replenishment at twice the previous (manual) rate and necessitate an adjustment of the lubricant-fill cycle. Recognition of your working environment, and tailoring your lubrication approach accordingly, is the first step to implementing a "lubrication by design" method and, ultimately, achieving true lubrication effectiveness.
