Yanmar NT65K

My recently purchased Yanmar NT65K water cooled engine. I bought it completely taken apart so it'll
be quite a puzzle to put it together again. All information about this engine will be most welcome.

Cheers

Niek.

That looks very interesting, it will be nice to see how you get on restoring it, thanks for posting photos.

that looks like a very interesting job indeed,the crank looks rather large for an engine of that size.
good luck with your project.you must keep us up to date with your progress.

Thanks, the crank is pretty big indeed. I will keep you up to date!

Hi Niek, Have you done any searches on google or Ask to see if they find anything? Do you know what application the engine is from? I would guess it's not marine or is it?

Good luck with the re-build.

Hi Stu,

I had a look on the internet but thus far I haven't really found anything useful. (except for some
sites in Japanese) I'm not sure what this engine is used for but I have heard that they were used
in boats and also to power milkingmachines.

Today I removed the crankshaft bearing and found it to be completely shot. I asked the local "blacksmith" whether new parts could be ordered. I also bought a similar NT65K without a cilinderhead via the internet for spares. I'm currently waiting to pick it up. New pictures coming soon.

cheers

Niek.

This is a (something got wrong with the camera) picture of the bearing.
I'll make a new photo tomorrow.

Hi,
Using for years a Yanmar NT65K in a generator set I am now searching for a manual of this smooth-running engine
Was asked before, I know, but who knows?
Regards, ( and a happy new year!),

Hi Hendrik and welcome to the forum.
I wish you luck with search - I've run bots a few times and never got a hit.
Maybe contact Yanmar in Japan and see if they can help. There is a big stationary engine following in Japan.
