Channel Strut as a Motor Sub-base?

| | | | |

By on April 12, 2018

At first thought it may sound like a good idea as the specialized fasteners in the channel make it easy to tighten the motor hold down bolts, however in reality it’s a cause for precision shaft alignment issues. Here’s why. A good pump/motor base is engineered to meet specific standards (IE: ANSI, API, etc.) with […]

Challenging, But Not Impossible!

| | | | |

By on April 3, 2018

As we trainers travel around the country conducting precision shaft alignment training, we often run into some fairly harsh work environments during the field portion of the training. At times the equipment that needs to be aligned is caked in product from spills or leaks. This can create a significant challenge when attempting a precision […]

Installation Errors Part 1- Coupling Care and Balance

| | | | |

By on March 28, 2018

Observing a training class of new mechanics can sometimes be a stressful proposition for a former field Millwright. Especially when said millwright has control issues.  As part of our Precision Shaft Alignment Training, the trainees move from the classroom setting into the field to practice what they have learned. Transferring the knowledge gained in a […]

The Soft Foot Primer (Part 3) How to REALLY Minimize Soft Foot Every Time

| | | | |

By on March 4, 2018

It is both possible, and desirable, to minimize the negative effects of soft foot.  While it may be difficult to completely get rid of soft foot, it can typically be reduced to a few mils, if the following techniques are used. PREPARATION AND CLEANLINESS CLEAN! If you remove the motor, wipe the feet clean, before […]

The Soft Foot Primer (Part 2) Vibration and Alignment Problems Related to Soft Foot

| | | | |

By on February 26, 2018

Most industrial maintenance mechanics who are involved with precision shaft alignment are familiar with the phenomenon of soft foot.  From an alignment standpoint, soft foot causes: Changes in alignment values, between when the hold down bolts are loose, and when they are tight. Non-repeatability in alignment measurements, especially if the bolts are not tightened in […]

Stupid Questions

| | | | |

By on February 8, 2018

While on the road conducting precision shaft alignment training I run across a wide range of skill level. It is not uncommon to have a lot of questions. I like it when there are questions, that is usually an indication that the trainees are engaged. It is also not uncommon that a question starts with, […]

X, Y, Z Axis. What do they stand for?

| | | | | |

By on February 1, 2018

Everything must have perspective, a point of view, to be communicated. To communicate the three spatial dimensions, we use the X,Y, Z coordinates. These denote height, width and depth. In referring to machinery we use the same X,Y, Z denotations, but we give them different values or meanings. To make it even more interesting, there […]

The Role of Fasteners in the Alignment Process

| | | | |

By on January 24, 2018

Fasteners are a critical component of the precision shaft alignment process, yet the importance of fasteners is many times overlooked.  If bolting is not selected, assembled, and torqued correctly, it can make the precision shaft alignment process less accurate, more difficult to achieve, and potentially harmful to the machines. While there are always unusual circumstances, […]

Plan Your Work for Quick Alignments

| | | |

By on January 4, 2018

We have been teaching maintenance personnel to use the Verti-Zontal Process to perform precision shaft alignments quickly for years. The key to quick alignments is to follow the Verti-Zontal plan which includes the pre-alignment steps Obviously when alignment checks are done, the pre-alignment steps aren’t performed on the “front end” of the alignment however they […]

Why You Should Perform Shaft Alignment as Part of Your PM

| | |

By on December 27, 2017

James Pekarek, one of our trainers, wrote a blog entitled “Performing Alignment Checks as Part of Your Preventive Maintenance”. https://vibralign.com/shaft-alignment/performing-alignment-checks-part-preventive-maintenance/ It is a great article, and good advice.  I recently shared this blog post, and the advice, with a customer of ours.  Here’s why. I taught a training class at a large water plant in […]

What is Misalignment Costing You?

| | | | |

By on November 16, 2017

I recently received a support call from a nearby client, the issue was that the precision shaft alignment of a right-angle gear reducer to a line shaft was taking up to 12 hours (using another brand alignment tool) with little to no success. There are about a dozen of these units in this facility. This […]

What is the Fixturlaser NXA Runout Probe?

| | | | | | |

By on November 7, 2017

VibrAlign has introduced the Fixturlaser Runout Probe, an accessory device for the Fixturlaser NXA Professional.  I (as a jaded, grizzled old millwright-but a good “company man”) was outwardly excited.  But inside, I thought, what’s the big deal?  It’s an electronic dial indicator. That’s what I thought – until I took it for a test drive!  […]

Fix the Easy Things First!

| | | | | | |

By on October 26, 2017

One of the hallmarks of a good maintenance technician is the ability to troubleshoot – not just using vibration tools, or volt meters, or laptops with Ethernet plug-ins, but the ability to troubleshoot machinery in their minds.  In other words, the ability to visualize what the problem might be. “Fix the easy things first” is […]

The First Rule in Precision Shaft Alignment is “Don’t Assume”!

| | | |

By on October 6, 2017

This is an obvious statement and most of us know what happens when we do “ASSUME” with most things in life. However, we (The VibrAlign Trainers) see assumptions being made quite often during a precision shaft alignment. Several years ago, I read a book titled “A Millwright’s Guide to Motor/Pump Alignment” by Tommy “T-Hammer” Harlon […]
