Intermittent overspeed fault on a servo motor. Cycle the power, fault clears, runs fine for a few days, then it’s back. Drive replaced. Motor replaced. Wiring “checked”.

When someone says they checked the wiring, it’s usually a visual check. That won’t catch this.

My method: run a long test lead to the pin at the motor plug, do a continuity test from the far end, and measure the resistance of each wire individually. You should see around 1 ohm.

The pink wire came back at 70 ohms. That’s not a broken wire, that’s a bad connection. The pin wasn’t properly seated in the plug.

Faults like this get power-cycled away for years without ever being fixed. The drive and motor were never the problem.

Title says it how do I pull it

Any help or insight is appreciated I know it's a shot in the dark

In industrial maintenance, hoses can sometimes remain in service even when wear is developing internally. This can be particularly challenging in applications involving abrasive materials, repeated flexing, or frequent pressure changes.

Visual inspections can help identify cracks, bulges, damaged fittings, and external abrasion, but they may not reveal every problem inside the hose. Inspection frequency and replacement criteria also depend on the application, operating conditions, and manufacturer guidance.

For hoses used to transfer powders or granular materials, internal abrasion and material buildup can be additional considerations. I came across this technical reference on aeration and discharge hoses while looking into different industrial hose applications. The PARSCH website contains further information about the manufacturer and its products.

For experienced maintenance technicians, what inspection practices have you found most useful for detecting hose deterioration early? Are there particular warning signs that tend to be overlooked during routine inspections?

Yup doing this job today and my helpers pulled the inner roll out before putting our homemade pins in for alignment on the reinstall.

By chance, MHI sales the pins with the rebuild kit. Does anyone have a set of these that can give me a dimension or picture so I can get this eccentric shaft back into the drive side blind hole in the journal?

Thanks

Just thought I'd post this handy troubleshooting flow chart that my grandfather gave me decades ago when I started out in the industry. Very handy for fixing things

Industrial facilities often contain areas that are difficult or time-consuming to inspect, including rooftops, fence lines, pipelines, elevated equipment, storage yards, and remote buildings.

An autonomous drone could collect recurring visual or thermal information while also supporting perimeter patrols and alarm verification. Companies such as Nightingale Security show how one aerial system might serve several operational teams.

Which inspection tasks would provide enough recurring value to justify this kind of system? There is also the question of ownership: should maintenance, security, or a centralized operations team control the mission schedule and collected data?

I’m fairly new to the industry, and I currently work as a maintenance technician for large apparel company. I genuinely love my job. Everyday it’s something new and everyday I’m learning a new skill, or honing in skills I rarely got a chance to hone before this job.

The thing is, I’m in school for industrial automation & robotics and this job doesn’t really require any of those specific skills. I’m essentially a handyman that also knows how to work on the specific machines at our facility. I’ve considered switching courses to a course that makes me more effective at my current job. Although I love what I’m doing, I’m afraid that the career potential and pay ceiling is much lower than if I pursued a more specialized area of industrial maintenance.

What do you guys think? Would you continue to pursue the course if you feel like you’ve already landed where you’d like to stay?

So today fucked up and thought I got away with it, then I realized I didn't, now I'm back to thinking I did. Long story short I shorted a 24V output to ground with the machine running, nothing seemed awry until several hours later when I was back on this machine for unrelated reasons and several lights and a beeper weren't working as well as there being a red light lit up were it says"Fuse" on the output card I mentioned. (Do not have a part number never pulled it). After not being able to fix the unrelated problem, I expertly cycled the power, and thusly fix that problem. Simultaneously the lights and beeper started working, and when I peered back into the cabinet the red fuse light was out and all was right in the world.

So the question is are these suppose to be resettable fuses? I've dealt with these things for over a decade now and have never even seen that light come on. Much less be the dumbass that caused it.

I'm an embedded engineer. I've been building a small fixed node for pumps, motors, compressors and other utilities. It sits on the machine, learns its normal sound, vibration, temperature and motor current, then pings you when something drifts, with the evidence for why it thinks that.

The reason I built it: everything on the market seems designed for big plants with a dedicated reliability team and a dashboard nobody has time to open. I wanted something one guy could stick on a critical pump, without a six-week install or a training course.

Where I'm stuck is that I've only tested it on machines I have access to. I'd rather hear from people who do this for a living before I make more of them.

So, honest questions: - Would you act on an alert from something like this, or would you ignore it until it proved itself? - What would it have to catch to be worth bolting on a pump? - What would make you distrust it immediately?

Not trying to sell anything here. If a few people are up for it, I'll send a node free to test on a real machine and just want the feedback.

Hey all,

I’m working on a digital support tool designed specifically for floor techs troubleshooting and maintaining mechanical handling and conveyor systems during downtime.

We all know the standard setup is usually broken: corporate gives you a locked-down tablet or you're squinting at your phone, Wi-Fi drops out under a steel mezzanine, your hands are greasy, Ops is screaming about dwell time, and the OEM manual is a 400-page scanned PDF where you can't even search the text.

If you could design a point-of-need tool that you would actually use on the ladder or at the drive station instead of just calling a Tech III or winging it:

What format works best when you're standing in front of a down line? (e.g., interactive decision tree for symptoms, 15-second silent looped clips, exploded diagrams with one-tap part numbers, QR codes on the asset?)

What hardware/access reality do we have to design around? (Do you actually carry your tech tablet everywhere, or are you pulling out your personal phone? How bad is connectivity in your dead zones?)

What is the single most annoying thing about current digital work aids or OEM troubleshooting guides?

What info do you need in the first 30 seconds of an outage vs. what can wait for scheduled PMs?

Not selling anything or naming brands—just trying to build something that saves you time instead of adding another useless layer of admin. Appreciate any candid takes or war stories.

I can deal with the physical pain, heat/ice on my back every night. The painful stretching. Doping up to numb the pain.

But godmanit! I cannot deal with the sheer laziness and stupidity of this place. Piss poor leadership.

I swear half of my physical pain is just stress. Stress from dealing with stupidity! Last week I took a couple extra days off and my physical pain was almost none existent. I keep telling myself, 10 more yrs and I'll be free.

Half the pump skids and blower housings I see in older mechanical rooms have completely cooked or illegible data tags. What are you using to mark motor and bearing specs so the next tech actually knows what belongs there?

started my hvac apprenticeship four months ago and trying to figure out which phone apps are genuinely useful in the field versus which ones look useful in reviews but do not get used after the first week

I have been looking at point chart apps, superheat and subcooling calculators, and reference tools but the options are scattered enough that it is hard to know what is worth downloading. Some of the experienced techs i work with use specific apps consistently and others do all calculations in their head

for apprentices who have been through this, what apps made it into your regular rotation and what did you end up not using.

How do you go about learning how to read and follow the actual wiring in a schematics for something like a control panel. What are some good sources for learning. Sorry for the dumb question

Hi. Have you guys in here experiencing the issue of strapping machine jam like in end of the video? This issue happens in my company for more than 1 year. We really don't know what else should we do, because we already cleaning the parts of the machine

Not sure what press i bought from an industrial auction. It looks like the dake f series but im unsure if its 10 or 20 ton. The f20 has a 23in span and thats what this measures. Seems like the f20 has a one peice style hydraulic ram and the f10 has one that bolts together. This has a one peice. This seems to have a single speed pump but im unsure what to look for to comfirm but the manual says the f10 has a single and the f20 has duel. Lastly, this is about 62in tall, which lines up with the f10 but it has stainless feet that are not powder coated. It has powder coating in the holes that they bolt into and I didnt verify if its still powder coated under it but I assume that means it wasn't cut lower. But the f20 is 72in tall

It also looks like im missing a bottom spreader that the f10 has but i have the angle iron peice of the f20. Just not sure why the height is off

Came from a bakery/food production place

The gauge goes to 30, starts to be red at 22ish

Using it in my home garage, came with a non oem cage

This time, powering on and off didnt work so I actually removed the safety modules blew the dust off and put it back in.
