Three O&M Lessons Learned from a Career in Motion Control
29 June 2016
Ron Gramza is the technical service manager at Moog Industrial Group, a part of Moog Inc. and a maker of high-performance motion control solutions for industries such as power generation, test, flight simulation, metal forming and presses, wind energy, automotive, and oil & gas. During his twenty years with Moog, he’s seen a lot of approaches to the repair, maintenance and overhaul of industrial applications. Below are three lessons he’s learned; we encourage you to download the full document here.
Lesson one: Monitor oil cleanliness results. To keep machines up and running, develop a routine schedule for key items like rotational gear (e.g., pumps and motors); replace filters and watch for leaks. If oil is leaking, contaminants can affect performance.
Lesson two: It may sound self-serving, but always turn first to your OEM for repairs. You might get cheaper repairs from an unauthorized repair house (URH). But that same part will need many more repairs over the next one or two years and will ultimately cost you more. Ron once had a power gen customer call and request a same-day service on a repair. He quickly looked up all the possible parts that could be required and provided a quote. Ron then asked the customer where he was located. The customer told Ron he had already sent his corporate jet with the valves to Moog’s factory. The customer was so time-pressed and frustrated with the URH that he resorted to desperate measures. Moog fixed all the valves the same evening, and the customer’s jet returned with like-new product and got his machine back to business immediately.
Lesson three: Incorporate failure analysis into your maintenance. Failure analysis gets to the root of a technical problem via highly detailed photographs or rigorous elemental analysis. Imagine how a highly magnified photo of a corroded flexure sleeve could be the result of moisture in the hydraulic fluid and the acidity being too high. Or perhaps analysis finds something lodged in the first stage of a valve. At Moog, failure analysis consists of sending items to its materials lab for extensive analysis using high-tech equipment the likes of which you’ll see in Hollywood TV shows and movies.
Maintenance managers are always challenged to do more with less. Keep in mind Ron’s three lessons, and you’ll spend a lot less on maintenance in the years ahead. Download the full document or subscribe to the Lessons Learned series.
