Over-lubrication kills gearboxes quietly, on equipment that gets regular PM attention, by technicians following the checklist exactly as written. The failure looks like overheating, seal failure, and oil breakdown —... Read more...
Gearbox Oil Analysis: Why Most Programs Misuse It
Gearbox Oil Analysis: Why Most Programs Misuse It
Oil analysis doesn't fail because the tool is wrong. It fails because most programs treat a single sample like a verdict instead of a data point. One result tells you... Read more...
Why Gearboxes Fail — and the PM Checks That Prevent It
Why Gearboxes Fail — and the PM Checks That Prevent It
Gearbox failure doesn't happen suddenly — it's built one deferred inspection at a time. Oil condition, thermal drift, seal weeping, gear tooth wear: the signs are there long before the... Read more...
Industrial Gearbox Preventive Maintenance: Failure Modes and PM Checks That Actually Work
Industrial Gearbox Preventive Maintenance: Failure Modes and PM Checks That Actually Work
Changing the oil on a schedule isn't a gearbox PM program. It's a starting point that most programs never get past. Here's what the checks that actually prevent gearbox failures... Read more...
Industrial Counter PM Checklist: What Fails, What Gets Missed, and What to Check Every Time

Soft Starter PM Checklist: What to Inspect, Test, and Document Every PM Cycle
Soft Starter PM Checklist: What to Inspect, Test, and Document Every PM Cycle
Soft starters fail quietly — degraded thyristors, loose connections, clogged cooling paths, and a bypass contactor nobody checked in two years. This checklist covers what to inspect, test, and document... Read more...
VFD Preventive Maintenance Checklist: What to Check, How Often, and Why It Matters
VFD Preventive Maintenance Checklist: What to Check, How Often, and Why It Matters
VFDs don't announce their failures. They absorb bad conditions — dirty power, blocked airflow, aging capacitors, loose connections — until they can't anymore. Here's what your PM program should be... Read more...
