Listeroid Engines / Re: Proper Heat Management for Listeroids
« on: August 20, 2024, 03:36:39 PM »
Not really. As the coolant falls down by gravity it doesn't purge the air, it just rolls down through it. Since the air is not a good conductor of heat, the radiator doesn't transfer the heat to the radiator. Pushing the coolant up from the bottom does purge the air out the top. It's amazing what a different it makes in extracting heat from the coolant.

Listeroid Engines / Proper Heat Management for Listeroids
« on: June 19, 2024, 08:54:02 PM »
Hello All,

        I sell Listeroids and I have a suggestion for setting up your cooling system. The problem I've found with installing small automotive radiators is bleeding the air bubbles. Many of my customers have complained about overheating this way and simply "grown" their cooling systems for big $$$. Bigger radiators, more coolant etc.  I have found that the old NASCAR trick of feeding the engine coolant output into the bottom or the radiator works wonders. The bubbles automatically purge out the top. With the conventional plumbing of in the top and out the bottom on my 10/1 demo unit and the 180F thermostat stayed open, the electric fan never started and the recovery tank started over heating. But reverse the flow and the thermostat never opened releasing only the bleed volume through the closed thermostat. The fan started on a 50% duty cycle and the temp stayed at about 160F. Same load just different heat management.

Hello All,

        I sell Listeroids and this problem with heat management comes up a lot. For starters 220F is too hot, should be 180F Max. The problem I've found with small automotive radiators is bleeding the air bubbles.  I find that the old NASCAR trick of feeding the engine coolant output into the bottom or the radiator works wonders. The bubbles automatically purge out the top. With the conventional plumbing of in the top and out the bottom on my 10/1 demo unit and the 180F thermostat stayed open, the electric fan never started and the recovery tank started over heating.

Hi Bob,

    Sorry don't sell the models for Oz, since they'd have to run upside down right  ;D  We are 100% within the rules. Sell a basic core and a parts kit so end user can configure as they need.

Hey Eric,

       Yep getting things "dusted off" and putting on my "Big Boy" pants as the good weather hurtles toward us. I've layed out the slab for the generator shed. I'll probably pour within the next couple of weeks. I plan on making and linking a video of the build and configuration to my WEB site. A lot of my customers are asking for some guidance on how best to install a system. The video should be very helpful in that endeavour. I look forward to input from folks here on the forum as things start shaping up. I haven't forgotten your throttle linkage. Before my next factory order I'll give you a call to make sure we get the one you need.

Hi All,

    If anyone is looking for a new Listeroid for On or Off Grid power production I can provide them. Things seem to be getting a little "exciting" with the power grid and in general in our country, so I'm seeing an increased interest in Listeroids. I have a few 10/1's left in inventory now and will have other sizes in the near term. They are available as either a prime mover or with a brush-less alternator kit. These can be seen on my WEBsite  http://www.boltonpowerequip.com  If anyone is interested or just has questions, drop me a note or reply with a post.

Thank you for explaining that again to those of us that missed it the first time.

I now understand the reason you think your engines will last 50K hours and be superior not having the problems other people encountered with these engines and manufacturers is because you told the smart Indian Business men that if they sold you good engines, you'd buy more.

I'm sure that promise of future orders of what?  5-10 machines at a time,  changed the outlook of every worker in the factory and inspired them to all take a level of pride and care in assembling these engines like they have never done or even know how to do, like ever before.  No doubt the managers and owners of the plants will also be encouraging their workers to slow down and take their time to ensure every one of the engines they build for you prioritises quality over the usual Quantity targets they push for. 

If there is one thing your comments have proven far beyond a shadow of a doubt in my mind, it's the Vindication of Bruce's statement that you haven't got a clue about the quality issues of these engines nor done a thing to address them.



How many 3rd world factories have you been too?? I've been to 5.. How many export managers have you had dinner with and discussed how they could meet their quotas? At least 5 for me. How many containers of equipment have you imported? No idea for me, lost count. It's very simple. I'm going to use an approach that has worked well in the past and give it a whirl. So far nothing to indicate that it won't produce a viable product as it has in the past. I have an open mind, do you?

Guys, let me say this again because it seems most of you missed it the first time. I didn't say I have the perfect mousetrap or a secret sauce to make the perfect listeriod. I said I've seen this movie before in China and I know how it ends. One of you said "China is not Rajkot". Well no it isn't, today. But it was 25 years ago when I started looking at Chinese tractors. I visited the factory and they were all hand made by dudes squatting on a dirt floor with hand tools next to a wooden cart with hand made parts on it in a room with no doors, sort of like a Chinese public bathroom, but thats another story. We had all the same issues with boring tool run out, milling tool chatter, misaligned holes, missing process steps, you name it. One importer called RHINO out in California just brought in containers and had so many problems it ultimately finished the company. I asked the product manager in China if the RHINO people had ever visited the factory and he said "no". So I went over there a number of times and looked at what they could do and what they couldn't do well. I didn't buy certain accessories from China, I had them made here in the US or Canada until they could make them well enough, some they never did. In one case we had milling facing problems causing leaks so I asked them to double up on the gasket. I also bought enough tractors to have their attention when I came to visit. Bottom line I fine tuned what I had. Listeriods are the same. Many of you are talking about how they don't have tight tolerances. They don't, but they don't need them. You can get 10 Hp at 7,000 rpms out of a 5 lb aluminum chainsaw motor, but it better be C&C designed and patterned along with very good materials QC or it won't last very long. But a listeriod weighs 1,000 lbs and turns at 1,000 rpm max. A few thousands off on the bore isn't going to matter and you don't need to magnaflux a 50 lb. 10Hp crankshaft that turns at 1,000 rpms. With a 400 HP engine it might be a good idea. With a 500 lb. 10HP crankcase you don't need ASTM grade cast iron either. That engine is so over designed it will be running long after the chain saw motor is shrapnel. The Chinese solved those issues much the same way by over designing the product. I've spent a few years testing these things and what I see is exactly what I expected. An over-designed 100 year old design that stills works for a reason. If Indians are one thing they are smart business people. I will buy volume as long as they give me what they can, not what they can't. Same offer I made the Chinese and I never had quality problems. Rhino did, I didn't, same factory group. The Chinese today have come a long way with manufacturing but 25 years ago it was Rajkot today. I will deal with the manufacturer the same way and get a consistent and acceptable product. I've already decided on buying some parts here, just like I did with the tractors. No magic, just knowing what you have.

Diesels last a long long time. A listeroid is an over designed extremely low stress e.g. yield, engine. 

It would not surprise me at all to see a well maintained listeroid chugging away at 50,000 hours.

Mate I don't know if you have done any reading here or just come to push your business interests but you are talking to people who pretty much at a Minimum, have a decade of experience with these things on their own, and probably several centuries combined. You are talking to many people whom in some cases have torn down, modified and rebuilt dozens of these things. And you are trying to tell them you know better after playing with a couple for a couple of years.  I'm sure you can see the credabiolity problem there.

If you go back through the loads of info here again going back over 10 years, you will see people well understand these things and their abilities and limitations. Unless you have re invented the wheel, there is nothing to say your engines are any different or better than the ones people have been playing with  for a VERY long time.

Describing what is well known and making predictions that in no way add up to the hands on experience so many people have with these engines in all their different sizes and flavours, is not going to convince anyone nor change their minds. 
From what I can tell, you have a few years experience playing with these things but you are trying to tell people whom have relied on them daily for years and torn loads of them apart, that what they know is wrong.

From what I can see, the sum total of your experience with these engines is you have been testing a couple ( or was it just one actually used) for a couple of years. That means absolutely nothing. I have had one of these things about 10 years but there would be a bunch of people here that would run theirs more in a month or two than mine has done in it's life.  Exactly how many hours has this test engine of yours done?  I know for a fact the engine I have is a complete and utter piece of garbage with every known fault these things have but it's probably done a couple of hundred hours and runs fine too.  How it runs at 500 hours and beyond I expect would be a very different thing.

Are you even aware of the common problems with these engines and what specifically have you done to address them? If you listed those you would have a lot more traction in trying to convince people the engines you are selling will be different and more reliable.

Sorry, but what would or wouldn't surprise you or what you think is really insignificant to the decades of hands on experience people here have with these engines and the information they have shared which pretty much all flys in the face of your own. Which to be honest, is nothing more than sales Hype rather than anything remotely technical or detailed .
You have actually posted ZERO information or details that would change anyone's mind that you have overcome the mountains of documented problems these engines can have due to the terrible manufacturing practices and non existent quality control from where you are sourcing them that is the same place everyone else has.
Have you even been to any of the factories and seen and spoken to those making them first hand or has this all been organised through emails?

Did you tear either of these engines down you tested at any point and check them to be in spec and assembled correctly or did you just take the assurances of the person you bought them off because they said the right things you wanted to believe? Without a teardown and measurement, you are kidding yourself far more than anyone else.  I see nothing so far that suggests that you have done anything but run them.... for unknown hours with an unknown load. 

I understand you are trying to push these things and have a financial vested interest in them and therefore want to show them in the best light. Unfortunately You are completely and utterly out of your depth here with the experience and knowledge many have ( and I'm NOT talking about myself)  but as disagreeable as some here can be, their opinions formed over many years and with at least 10's of engines will always be what I and pretty much everyone else goes with, especially as it completely agrees with my own limited experience. It will take a LOT for you or anyone else to come near the respect and believability people here hold that have already commented here.


You may be better off spending your time trying to push your beliefs of these things to less experienced people else where because I really don't think you are going to do much good trying to sell your Yellow snow to this Village of Eskimos.
Where you might get better returns for your efforts is to look at importing spare parts. These are always in demand ( despite the engines running 50K hours) and there would be I believe a better and more profitable market for them.... If you can compete with the other established people doing it in the limited market that exists.

Unless you can PROVE different, what you have is the same engines everyone else has. That's OK though. Just don't try to over hype them and tell people they are something they are not and that's good enough. The engines are well known to this audience, just make the things affordable and available and you are there. Plenty of people will buy them for what they are with all their faults and problems IF they can get them at a reasonable price. You'd do a lot better to be honest and say these things typically need work to get them right than try and tell them you think they should last 50K hours when I myself have yet to see anyone with EXPERIENCE claim that yet.
Just get the things into the US at a reasonable price and 90% of the work will be done then and there.

As one sales person to another, You are going to have to hit this audience with a lot of hard and documented facts to win them over that you have a better mousetrap and change their minds. Talk alone is not going to come near doing it.


I guess you're right, what could I possibly know about diesel engines from the 3rd world? I only imported them for 20 years. 300-400 tractors and maybe twice that in small engines for generators and pumps. Been to the factories frequently and talked to the product managers and engineers. But how could I understand what they were talking about, I only got both my engineering degrees 40 years ago? Diesel engines from India don't use the same physics, chemistry or metallurgy as diesel engines from China so how could I compare them? So I wondered where you earned your engineering degrees, how many diesel engines you have imported and how many years you have been in business?? Curious.

50,000 hours !

In 10 years the average car engine only has approx 10,000 hrs.
(average 3 hrs per day X 365 days X 10 years = 10,950 hrs)

50,000 hrs / 5 hrs per day = 10,000 days ( or 27 years ) of running every day without major overhaul.

Based on the service work that is discussed here by members, I would say your claim is off by about 24 years worth of running.


Diesels last a long long time. A listeroid is an over designed extremely low stress e.g. yield, engine. To put it in perspective years ago I had an 88 F250 truck with a 7.3L IDI diesel. I put 500,000 miles on that engine with zero failures that required road service on the engine. Batteries and tires yes but never anything broken in the engine. The only parts I ever installed on that motor was a set of glow plugs and I replaced a dripping injector, just one. 500,000 miles and maybe an average speed of 30 mph is about 17,000 hours of run time. Maintenance yes, but no failures. That V8 7.3 was much much more complicated than a listeroid and it weighed maybe twice as much, but put out 20X the power.  When I sold it because the body was shot the motor was humming like new and burning no oil. It would not surprise me at all to see a well maintained listeroid chugging away at 50,000 hours.
A Listeroid work engine used most days of the week should need some considerable service within 4 -5 years.

I had a couple of eval units in the US, one left, a 10/1.

 I'll be putting in an order within a month or 2.

So they aren't exactly Flying out the door then. Might explain why the Chinese haven't taken them on.
Once can deduce your total experience with these units you think will be different to all the rest is exactly, 2.
Kinda.

I haven't offered any volume for sale yet. I've been testing. Same thing I did with the tractors. After 2 years of testing I'm comfortable with them and will start importing but just like the tractors I'll start slow and build the inventory that sells. Again same approach with the tractors. It took 3 years to go from the first tractor to 1-2 containers per month. I anticipate the same with the listeroids. I'm in no rush, I'd rather do it right. People have every right to be cautious , it's their hard earned money. But when the first volume units are deployed the owners will speak well of them and that word of mouth will ramp the business. Same as the tractors. Listeroids aren't mass market, they are a niche product, but a very unique and useful niche product.
