The Disappearing Art of Maintenance

I think in general the human mind treats Maintenance as less important or not important at all. The ancient people realized this: When I studied Chinese in primary school, there was one ancient text that spoke about a discussion between a king and a famous doctor. The doctor explained that his brother was superior than him in the medical science but no one heard about him because he could always treat small illnesses before then evolved into terminal ones, so people said, &quot;Oh he is a fine doctor, but he only treats minor illnesses&quot;.<p>This text has been resonating with me for many years. Humans simply do NOT appreciate maintenance people TBH. Me as an example: I own a house but whenever I plan maintenance of my house I always tried to push it a bit further because 1) It&#x27;s expensive, and 2) Manual or company says that I need to do X every Y years, can I push back say 10% and still don&#x27;t break things? As for my electronics, unfortunately I never maintained them and in my earlier days I never had a computer that lasted for 3+ years -- they always broke down due to this or that reason.<p>And then both of my knees have degenerative issues; I had kidney stones; I need to maintain physical health but I was and still is too lazy to do that. I simply do not have the maintenance mindset.<p>This probably can stretch out to the whole society: We simply do not appreciate Maintenance people. They are usually lowly paid and have low moral because what they work is chore. They also do not get to enjoy creating new things. Basically you need someone who has the mindset to appreciate maintenance to be a good maintenance person, and a society of this mindset to support such work and lower the cost. Nowadays we do not. Nowadays we always doubt the necessity of maintenance and sometimes even accuse other people to charge a large bill for maintenance (sadly, this could be true). There is little trust between.

I work in maintenance in the steel industry. To find good people is hard, today if somebody has more than two brain cells, the do a lot of study and never really start to work with there hands. I see it now, at moment several people get retired at our company. Instead one smart guy who did everything, you need know one guy for paperwork, one guy for his brainwork, one guy for what he did with his hands .. and one guy more to coordinate these three guys.<p>Also today with computer everywhere .. before you changed a setting with a screwdriver on a poti, now with computer everywhere .. your installed version is to old, download the latest version, try to install, it fails because the company has tight security rules on companys computer, try on a airgaped notebook for technic, it fails now because you can&#x27;t install or license the software because no internet .. to keep software up to date and running for over 10 or 20 years is just a f**ing pain. And it gets worse ever day.

Making maintenance easier requires a fair amount of industry-wide standardization and interoperability, and many corporations view this a threat to their market share and hence, profitability. This has been widely seen in the computer industry over the years, although the long-term conclusions might oppose the short-term view, i.e. while at first the closed-system strategy might succeed, in the long term having an open-system approach will bring in customers who&#x27;ve been burned in one way or another by the closed-system world.<p>A particular example I&#x27;m very familiar with is bicycles - they&#x27;re fairly easy to maintain and work on relative to automobiles (no fluids, not much electronics until recently etc.). Ideally a bicycle can be maintained easily and replaced piecemeal from a wide variety of suppliers, i.e. everything is swappable and there are no non-standard parts, such as weirdly threaded bottom brackets or non-standard axle widths. Some companies have tried to do things like that - I think Shimano made an integrated brake lever&#x2F;gear shifter for a while, whereas most bikes allow you to replace each item separately. For example, if your bicycle frame breaks, you should be able to remove all the parts and install them on a roughly similar frame, even from another manufacturer.<p>As far as deliberately making repair more difficult in the hopes that people would toss their old devices and buy new ones, there&#x27;s good evidence for that with Apple, such as the introduction of pentalobe screws for no other plausible reason than making repair require specialized tools (IFixit&#x27;s comprehensive screwdriver kit is nice in that regard).<p>The solution is once again, governmental regulation and agreement on certain standards, for example requiring a standard USB-C connection for all phones sold in a given market, etc.

Is this a US thing?<p>Here&#x27;s a girl mechanic in China.[1] She&#x27;s from a small village in the mountains, was able to go to a technical school in Kumming to learn hydropower, and came back to her village. She has a popular YouTube channel, so she&#x27;s making money off of that, as well as repairing broken engines and generators in the village.<p>Having restored rusty Teletype machines myself, I&#x27;m impressed with what she&#x27;s doing. She routinely rewinds generator armatures, which is almost a dead art in the US. (There&#x27;s one guy in San Francisco who still does that, and he has a backlog. He never got to the Teletype motors I wanted done. Urgent projects for old freight elevators and industrial equipment keep him busy.) She&#x27;s an artist with an angle grinder, making parts from sheet steel. She cuts curves with an angle grinder, something usually done with a bandsaw. Her welding is so-so, but she is using a crappy AC welder.<p>The engines she works on, usually small Diesels in the 5-30 KW range, are very basic and maintainable. They&#x27;re a standard design in China from the Mao era. Look up &quot;R175 Diesel engine&quot;. Hand crank start, cooling system is a water tank you have to fill when you refuel, no oil pump. You can buy one on Alibaba for under US$200, shipping not included.[2]<p>There are people who post claiming she&#x27;s fake. But there are many hours of videos showing her work. Once or twice, there are indications of outside help with heavy lifting, but that&#x27;s about it. There are more informed nit-picks - getting paint on the mating faces of the cylinder head may cause leaks later, banging on bearings with a claw hammer can damage the bearing races, and those motors really need to go out the door with a motor protection circuit breaker (US$6 on Alibaba) so they don&#x27;t burn out the windings again. But all this stuff is overbuilt, to survive years of minimal maintenance in agricultural villages.<p>Although her electrical safety is scary. No strain relief where cables enter boxes, plain wires rather than nonmetallic armored behind walls when remodeling, standing in a stream while holding an outlet strip.<p>[1] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;channel&#x2F;UCpPt42tLH5FRk__ytvMsejw" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;channel&#x2F;UCpPt42tLH5FRk__ytvMsejw</a><p>[2] <a href="https:&#x2F;&#x2F;www.alibaba.com&#x2F;product-detail&#x2F;R175-Diesel-Engine-Engine-Single-Cylinder_60393287578.html" rel="nofollow">https:&#x2F;&#x2F;www.alibaba.com&#x2F;product-detail&#x2F;R175-Diesel-Engine-En...</a>

I think a missing part for the propagation of those skill is being able to learn it as a hobby &#x2F; side project.<p>I would <i>love</i> to take some classes (and sign up my teenage son, too), but the adult education classes that I could find in the Boston area do not teach basic woodworking, metalworking, electrical, engines skills anymore (I heard insurance is blamed way more frequently than lack of interest). I would gladly pay good money for tuition and access to a machine shop, but it is impossible to find any options.<p>Edit: to clarify, I am treating this as a hobby (I am happy with my job working on algorithms for things that fly), not a full-time trade program.

The ice maker in my Samsung refrigerator has failed. Too late, I now know this is common for the brand. The part costs £100 ($100). The fridge was kind of expensive, with a deli drawer, French doors, etc.<p>The refrigerant line for the entire fridge loops naked through the ice mechanism. Apparently, it is all too easy to nick the line, bricking the entire appliance.<p>Accordingly, no repair person will touch it. I’m moderately competent with mechanical and electronic things, and I would try it, but I’d like a second brain, set of eyes and pair of skilled hands. No one is stepping up, presumably to avoid dealing with the hassle we’d have if we fail, myself included.<p>I do like ice.<p>Do I:<p>a) Give it a shot myself risking a £2500 refrigerator.<p>b) Keep trying to find someone who will fix it. Offer them some kind of waiver on replacement cost if they fail.<p>c) Continue to make ice in trays, a few at a time, whilst the broken ice maker mocks me.<p>d) Get a countertop ice maker for £100.

I recently got bit by the pinball bug, and while reading this article all I could think about is that maintenance is part of the hobby. And for some it&#x27;s all the hobby.<p>Buying a pinball machine is expensive. Prices on used machines range from free to thousands (and ten thousand+ for really in demand ones). After you buy the machine, assuming it works, there&#x27;s maintenance that occurs on the machine as a direct function of how often the machine is played. Maintaining that machine can be on you for parts and labor, or someone who comes to your home for 100$&#x2F;hour (or so) +parts. There&#x27;s no escaping the labor. You have to do it, or the pinball machine stops working. The maintenance ranges from simple cleaning this and that, all the way to removing components from boards, and rewiring destroyed traces.<p>I love this about the hobby, and it&#x27;s probably my favorite part. I like maintaining the machines probably more than I like playing them.

The last time I paid a general appliance repairman to fix my dishwasher, he replaced it with a nonstandard part. It semi-functioned for another couple years, but it generally had a hard time self-cleaning its own filter, which lead to lots of strange and persistent problems. Eventually, the dishwasher failed, causing a leak that required a lot of the flooring around it to be replaced.<p>I should have just purchased a new dishwasher at the time that GE&#x27;s planned obsolescence part failed, right at the end of its warranty period.<p>So, what the article misses is that a lot of the suppression of maintenance providers is related to how our intellectual property regime has been crafted. The statutes and case law give corporations enormous power that they did not really have in previous eras to control supply chains and documentation. There are other factors feeding into this, but if you are looking for a solution to this set of issues it lies within IP reform first and foremost, although that would have its own set of tradeoffs and consequences.

I’m all about maintenance, but mostly in a literal sense. It turns out that there’s another definition of that word in the real estate world.<p>I sold a house a few years ago that the real estate agent described as having “deferred maintenance“, which annoyed me. Because I always maintain my houses scrupulously.<p>Fast forward a few years later and I now understand that phrase actually means “it’s not decorated in the current style“. The fact that I don’t spare gigantic expenses such as major electrical or floor repairs, massive septic field projects, replacing large drainage systems, central air conditioning, etc. all at tremendous costs, is irrelevant to people who use the phrase “deferred maintenance“.<p>They don’t care at all whether I just replaced a pool pump or expensive air conditioner just before selling. No one who buys a house from me is going to have to replace their pipes or ducts within the next 20 years, but that just isn’t a selling point.

I work in the tech industry. I&#x27;m somewhat rare in that I also work on my own vehicles, do my own maintenance, repair things, build my own stuff around the property, etc. A lot of coworkers at various places I&#x27;ve worked over the years view this as somewhere between &quot;eccentric&quot; and &quot;slightly mad.&quot; &quot;Why would you do that yourself, just <i>pay someone else</i> to do it!&quot; is the common sentiment.<p>But even with electronics, in an office full of tech workers, I still seemed to be one of very few who was willing to get my hands dirty. I had a steady side stream of evening projects repairing phones, laptops, etc (or, more usually, buying the broken ones, fixing them or merging them together into working ones, and then selling the working ones). I was also, far as I could tell, the only one in an office of &gt;1000 willing to do things like take a soldering iron to a laptop to repair a failed power jack, or even just do things like taking a laptop substantially apart to <i>replace</i> a power input board with a new one.<p>It never made any sense to me that I was the only one willing to do this sort of stuff. It&#x27;s paid off well over the years, but it&#x27;s quite baffling.<p>This, of course, means that a lot of new things seem to be designed by people who&#x27;ve never had to work on things or repair them, with the expected results of &quot;This is more painful to repair than it has any business being, because you never thought about it.&quot; Some of the best vehicles I&#x27;ve worked on over the years were old gen Subarus - EA82, so late 80s wagons. Every time I had to do something on them, it felt like the engineers had considered that someone would have to do this, and made it as easy as possible within the design. Things like the fuel filter were on the firewall, instead of under the vehicle out of the way. The fuel pump was on a skid plate in front of the tank, instead of in the tank. There was a storage compartment in the back that would fit a CV axle, should you want to carry your old one. Etc. They were simple, and easy to work on - so I drove them for quite a few years.<p>But even today, I still constantly see the sentiment that &quot;Well, it doesn&#x27;t matter if it&#x27;s easy to fix, we&#x27;ll just recycle it and build a new one!&quot; Usually in fields where recycling is poorly defined, at best - consumer electronics and EVs draw this sort of thing frequently. I view that as complete madness, because it&#x27;s always going to be cheaper to repair something (at least if it wasn&#x27;t a glued together hell to repair) than to crush it and replace it, but... again, this is an oddly minority view in the tech industry.<p>I&#x27;m not sure how to fix it. We have a lot of people who are afraid to get their hands dirty, designing the things that are supposed to be the future of our civilization. That&#x27;s a real problem.<p>&gt; <i>No amount of utopian dreaming can make a battery hold any more energy or a piece of steel bear any more weight than it’s designed for.</i><p>Yeah. That describes an awful lot of the problems we&#x27;re facing...

I attended community college a few years ago and took a pair of courses designed as preparation for CompTIA A+ certification. Our final project for the class was to refurbish a desktop computer and donate it.<p>Our instructor fired up a compressed air machine and we blew out all the dust. We checked connections and RAM, peripherals, optical drive, HDD, etc. We made sure the things booted and probed OK. We checked cosmetics on the front bezel and around the case. No wiping HDD or installing of OS was necessary here, it was strictly a hardware&#x2F;BIOS-level project.<p>Then we were graded and the refurbished machines were all shipped off to a local student-run project that provides usable computers to worthy organizations who need them. Definitely a feel-good project, all around!

The author goes into the whole Reduce, Reuse, Recycle part of things but I think they miss out on a current trend [0] that may be a subset of Reuse.<p>[0] <a href="https:&#x2F;&#x2F;www.repurposedmaterialsinc.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.repurposedmaterialsinc.com&#x2F;</a><p>This outfit takes in surplus materials, obsolete parts, etc. and sells them either to be reused as originally intended by a new owner or repurposed to accomplish a new task that the designer never considered.<p>Repurposing things allows us to keep a lot of stuff out of landfills and for many of the things they sell, extend the useful life of things that are obsolete in their original purpose but that aren&#x27;t close to being worn out.

I guess I’ll take the opportunity to throw in my hat… I’m currently running a very early-stage startup trying to address some of the brain drain and complexity in industrial maintenance. If you’d like to talk&#x2F;rant about your job and the pain points you have, I’d be all ears! Wouldn’t be a sales call, I’m just trying to talk to people at this point. Feel free to DM me if interested.

I&#x27;ve spent 30+ years designing and engineering consumer and medical products, mostly for high volume production. While I detest working on projects I consider &quot;instant landfill&quot;, the reality is that so much of our built society whether it be a toy car, a mobile phone, or a house, is designed to appeal to consumers. Consumers who want their phone to be light, waterproof, beautiful and more powerful than the last one they bought, and at the lowest price possible. Prioritizing things like that means that a lot is invested in specialized equipment, fixtures, and training for the labor force which manufactures their new shiny object. Duplicating that equipment and expertise is next to impossible on the scale of maintenance. Maintenance is more of a craft. Think about your local car mechanic vs the factory which produced the car in the first place.<p>Even in the factories where your new shiny consumer electronics products are produced, when Chinese News Year is over, and a bunch of the staff turns over, getting the production line up and running again with the same quality is challenging. Despite there being documented standard operating procedures, incoming and outgoing quality checks, etc... there&#x27;s a lot which is tribal knowledge and muscle memory of the operators. Even if things are highly automated (and you&#x27;d be shocked how much is done by hand despite all those magical How It&#x27;s Made videos), those machines need to be adjusted and tuned to keep from producing junk. This is all to say that so many things are on the hairy edge of working well. They&#x27;re not always so easy to disassemble and reassemble without destroying seals, alignment, calibration etc.<p>To a degree, some of this can be blamed on products becoming more and more electronic and miniaturized, but the reality is that so many things involve inseparable assemblies (whether it&#x27;s an heirloom chair glued out of wood, a PCBA, the drywall in your house, or a welded and painted autobody). While there are rework techniques for these, they&#x27;re never the same as following the normal process in the factory.

&gt;maintenance has to be valued outside of austerity, and right now it’s unclear if our current economic system is capable of that.<p>As we hit the backside of the carbon pulse that gave many of us a standard of living that Kings could only dream of as few as 200 years ago, the need to build things for the long term will once again take precedent.<p>The ability for governments and institutions to paper over reality shouldn&#x27;t be underestimated, but we&#x27;re eventually going to have to trade power coupons for natural resources, and those resources are finite, and the difficulty of extracting them from the earth is increasing.<p>The market driven insanity of freely using virgin material for disposable trinkets will correct itself in time.

An unpaid plug for New York Replacement Plumbing Parts: in 2004, we installed faucets from a company that soon went out of business. Were it not for NYRPP, we&#x27;d have been forced to buy new faucets after cartridges failed.

fwiw I&#x27;ve noticed that my 2016 vehicle is surprisingly low maintenance compared to previous generations of vehicles. From longer cycles for basic maintenance[2] to parts just not failing as soon as I was used to (eg, check out this article[1] about cv joints lasting 2-3x as long).<p>I wish i could say the same about home appliances.<p>[1]: <a href="https:&#x2F;&#x2F;bobistheoilguy.com&#x2F;forums&#x2F;threads&#x2F;how-long-should-you-get-out-of-cv-joints.128443&#x2F;" rel="nofollow">https:&#x2F;&#x2F;bobistheoilguy.com&#x2F;forums&#x2F;threads&#x2F;how-long-should-yo...</a><p>[2]: eg cars going from 3k to 5k to 8k miles between oil changes, kn&amp;n filters lasting 50k miles on hwy etc.

It&#x27;s all by design as a good maintainability is not good for business for obvious reasons:<p>1. It&#x27;s require much more efforts in designing and manufacturing and thus cost would be much higher.<p>2. It reduces failure rates dramatically and thus leads to much less sales.<p>3. It reduces revenues from servicing.<p>Examples:<p>1. Built in non-removable battery in electronics such as phones.<p>2. Glues instead of screws in electronics such as phones.<p>3. Soldered on CPU&#x2F;RAM in laptops.

&gt; “Maintenance must be valued on its own terms, and that means tearing down the economic system that rejects it.”<p>This is not how you get people to side with you about the importance of maintenance.<p>Honestly, if I have to choose between capitalism and valuing maintenance, I am going to go with capitalism every single time.
