I don't need it.  Go ahead.  I was just interested in these engines.  If parts are available, and they are good on fuel I will keep my out for one in the future.

Good luck bidding.

I would like to know your opinion of this engine listed on Ebay.  I am very tempted to purchase my first Chinese Diesel, but there are some concerns.  Are replacement parts available to do complete rebuilds?  This one was purchase in 1997.  Also, are they economical on fuel?  Lastly, with the right care and setup, will they be reliable in the long run?  In other words, are they rugged and long lasting - worth the effort?

I highly respect your opinions.  Thanks in advance.

I found this article which will impact the solar panel industry next year.  Not from where you would think however.  It does not come from the solar panel manufacturers.  It comes from equipment suppliers who sell to the solar panel manufacturers.  It will come out next year.

If you like these kind of updates, let me know.

Just found this article and it really looks promising.  They think this technology can be on the market within a year.

It comes down to how well the filter takes out particulates.   Regular "full flow" filters catch anything around 30 microns or larger.   A bypass can take down to 2 microns or less.  Of course it does this slowly, so it cannot be a "full flow" filter.  It will eventually get all the oil say several times a hour. 

Diesel soot in the oil is around 4 to 7 microns.  This is what I meant by "cleaning" the oil.  A good bypass filter will even get the soot.

There was no sand in my engine when I rebuilt it.  It is a Volvo MD1, and has an excellent casting.  The scratches you see came from little flecks of steel, very small and flat, from somewhere in the engine.  They had collected in the sump pan where I found them.  I imagine they would have easily been taken out of the system by a conventional oil filter, but this engine only had a screen.  They passed right through.

When I do start this up, it will have an oil filter on it.  This means I will have to install an auxiliary oil pump as I have seen in other installations.  This however will allow me to install a "bypass" filter to clean as well as filter the oil.  I have decided on a Frantz Filter.  Over-kill I know, but these engines are a hobby.

Great comments.  It really gives me hope.  I too have used synthetic and hope it has made a difference in my diesel car.  
Your system belongs in an art museum.  The paint job is incredible.

Interesting video on the different oil filters.

All input is appreciated.

Here are some pics of a single cylinder diesel engine, with a wire screen filter.  Did a lousy job as you can see in the main bearings and piston bearing.

I agree with everything you have stated.  I wish I had your set up.  I am a long way off from where you are.

I can replace the piston and rings, and valve guides fairly easily and plan on doing that.  It is just when I have to tear down the engine to pull the crank shaft because the main bearings are worn, for no good reason, that I start thinking there has to be a better way.  

You left out 70 percent of the engine,(gears, camshafts, oil pump etc).  When they are worn out or get lose, well you are really hosed.

I have some pics of main bearings I would like to show you.  How do you display images anyway? Can't figure that out.  
When I cleaned the housing out, there were little flakes of metal in the bottom.  They had no idea oil filtration was necessary for these small engines.  The throw away mentality of our society - I just don't understand.

Anyway thanks for your input.  Again I agree with you.  Sometimes it is hard to stare reality in the face.

I really don't have an answer to your question.  It all comes down to flow and filtering size.  If the video is right and all these large diesel engine companies, CAT, MACK, CUMMINS, DETROIT DIESEL, indicate a the 4 to 7 micron size particulates (which makes the oil black), are the most damaging to the engine, you will need a filter can catch this size of particles.

I drive a diesel car and the oil is always black.  To eliminate wear I use a fully synthetic oil.  Here I have just been piss.... in the wind.  Well the diesel engine I am rebuilding is not one I will trade like a new car.  It is at least 45 years old.  I has cost me dearly to purchase, and rebuild.  The point - I want it to last another 40 years.  I know it will because it is over built and can if I put the right filtering system on it, and then make sure there is oil in the bearings before I start it up (another large cause of wear).  

If done right, it should last forever.

Anyway, I have been doing some research and if you want to search it out, there are what they call Dual Bypass Filtration Systems.  I might put one on my car now I know better.  I just wanted to share what I have learned with everyone because I know there are those who feel about their engines the way I do.

Was it a special Motorguard filter or the regular run of the mill car/truck filters?

Is this hype or is there something to it?   Opinions?

Thanks Gentlemen

I knew I had seen it somewhere, I just could not find it. 

I have had some other thoughts on filtering.  Now that I see how the pump is set up, has anyone considered putting on the kind of filtration system which found in some bypass oil systems which can filter out down to one micron, meaning also filter out the soot. 

A regular filter takes out material 30 to 40 microns.  They can't do much better than than because they have to maintain full flow to the engine.  A bypass filter can do better than that because it filters less flow, but over an hour or so filters the entire amount of oil. 

This video demonstrates it.  http://www.youtube.com/watch?v=klcBRnyCSvo

Wondering if any of you have an opinion on it after you see this video.

Has anyone put a oil filtration system on their Listeroid / Lister engine?  I am rebuilding an old engine which has screen for oil filtration meaning there is no oil filtration.  I am putting so much work in this rebuild, I would like it to last for a while.  Filtration will sure help.
I understand this would entail a separate pump.  Any, and I do mean any, info would be appreciated.

I used to design big machines, which used big gearboxes.  I would have them made by Flender, now Siemens, up near Chicago.  When I would visit the plant I would go out and see the the big orbital gearboxes they were making for the GE windmills as they were a supplier for GE.  As I watched them through the years, they got better at what they were doing.  Finally, they put in a huge machine, which would run these big gearboxes under load for a specified period of time.  Then they would take all the lubricant out of the gear box, and have it analyzed, for any foreign material.  If they found anything, they would tear it down and find the source and then test them again.  
Oil as a lubricant works best at higher temperatures.  To say they do not have adequate lubricant for these gear boxes is just not correct.  
The biggest problem with these gearboxes, is that they are orbital in design.  They have planetary gears moving around in a big ring.  There is no place for any foreign material, a chipped gear, or any metal to fall out of the way.  It just falls to the bottom of the ring, and the next planetary gear that hits it is toast.  They do their best in heat treating to make sure the each gear tooth is not brittle but hard enough to resist wear, but nothing is always perfect.
From reading the posts, you have to realize, the gearbox oil is not the only thing that has to be cooled.  A generator is like a motor in revers.  It generates a lot of heat that has to be dissipated.
Your right about the Enercon now has a direct drive, but the inverters are huge.  Well the entire monstrosity is huge.
That is my two cents.
