Forum for air cooled diesel engines and clones

Good possibility. I will stay tuned to see if it fixes it.

Question, Can you buy OEM Yanmar parts to fix the bad parts in the Chinese engines?

I still have a Yanmar L100 hooked to a 28 volt DC genset I would like to sell. Perfect for off grid battery backup. I believe you would use it in a 24 volt system.

What generator are you running with you L100??
I built a 24 volt unit for off-grid using a Niehoff N1603 450amp Mil surplus alternator.
I can pull 200 amps with the alternator turning 1600 rpm.

The chinese replacement parts are described as fitting real Yanmars so I would think that Yanmar parts would fit the china clones.
Can't say for sure but they would be a good upgrade.

I can't tell what generator is attached, it is under an olive green protective shield. I would guess that it puts out about whatever 9 or 10 horsepower is capable of.

Its worth a try but may not work.

When I bought my 1980 US-version YM240 in 2003 I found the local Deere dealer had sold them new, and still had an 'Authorized Yanmar Parts' listing in the phone book. Fine, I went to see him. The parts guy went nuts on me. He had had too many bad experiences ordering factory Yanmar parts for gray-market imported Japan-market Yanmars. Customers then returned many parts because seemingly identical tractors could be at different revision levels or something. The guy was just plain unpleasant. I've never gone back. Hoyetractor sells NAPA-quality replica parts mailorder and that's all I've ever needed. Also, I've been told nothing will be sold without providing the tractor's serial number. Maybe to identify revision level, or maybe to shut out the gray-market versions.

After some reading it seems Japanese marketing adheres to a strict model of dealers licensed to to sell only in their own exclusive region and parts only for models they are authorized to sell - just a cultural difference but I think that is binding on Yanmar Marine dealers worldwide and possibly tractors, and small engines.

Hopefully you will find the small-engine OEM market is friendlier than this.

Hoye Tractor.. is good.
another choice would be to search the marine side..
The marine version is the same as the non-marine version, except for the exhaust manifolds..
MOST of them are in sailboats.. & "sailboat people" are a different breed..

Honda engines were one of the first engines that I'm aware of that the Chinese started cloning. My local small engine shop (good friend) uses Chinese parts quite often with good results for repairs not only with Honda engines but chain saws as well. He ordered a real Honda V-twin engine for a customer and found it a small tag (made in China) customer was not happy.
Seeing that the Yanmar diesels are another favorite that the Chinese like to clone I would put a little money on the table and say the OEM Yanmar parts would fit the clones.
As I mentioned earlier it would be a good upgrade.

My newest Yanmar project.

I acquired a Landa pressure washer a couple years ago from a friend who was moving to Virginia and needed to part with some equipment.
The first thing I did was remove the Cast Iron 10hp Briggs and install my 9hp L90 Yanmar diesel that I had previously rebuilt with a new piston & rings. The original piston was broken from I assume the use of starting fluid.
Once the engine was installed I fired it up for a test and couldn't get any pressure.
It's a Giant brand zero trapped pressure type with a slow pressure rise when the trigger is pulled and it refused too build pressure so I moved on to plan B.
I had an old adjustable regulator laying around on an electric drive Cat Pump so I decided it was time to swap it out and finally have a high capacity pressure washer.
The pump is a General T1011 best I can tell. This pump shares many common parts with the T1011 2000psi, TS1021 3000psi and TS2021 3500psi but not knowing which pump I have I've set it for 2500psi..
The pump belt driven and under load is currently turning 1300 rpm and the engine is at 2800 rpm.
The pump is rated at 5.6gpm at 1450rpm & 4.5gpm at 1125rpm.
I installed a 5000psi gauge in the line and ran it up too 2600psi with no effort.
The Yanmar has electric start and a charging coil so I made a mount for the battery and necessary wiring to save my shoulders.
These Yanmars are amazing little engines needing only 1 good pull to start but you can't beat electric.
My current nozzles are rated at 3 gpm so new 5.5gpm nozzles are needed to fully utilize the power.
I ordered new #7 nozzles to utilize the full capacity of the pump.
The only thing I have left to do is fabricate a belt guard.
This is my 3rd Yanmar powered project and perhaps the one that will get the most use.
This machine came with over 100 ft of hose, wand and an adjustable nozzle.
This engine has a crankshaft for driving a generator so a tapered bushed bore pulley was used.
The end is taped to prevent corrosion.

Nice job. Just curious. Does Yanmar have different versions of engines for direct drive versus belt drive? I had a catastrophe fifteen or so years in with my low hour Diesel Mule. The crank shaft broke. Long story, short, apparently, the original motor was never speced for having a belt pulling on the crank. The replacement was a beefier crank that they used in the turbo version of motor.

Don’t know the answer to that.
Yanmar’s installation manual for the L series is very specific as to the angle the belt can pull on the crankshaft.
They prohibit drives that are above the engine.
Only fore, aft and below are permitted.

So that obviously has more to do with the construction of the block, than the stresses put on the crank itself.
