JACUSTOMER-qlie3drd- :

I'm sorry, but I think they hooked me up with the wrong man.


I am not working on a boat engine



Capt.Cory :

Oh, I did think it was a marine version. Sorry, I will opt out so someone else can help.


Thank you

Hello, I'm Wayne
I will help you with this
Good Evening

Have 34+ years at engine rebuild,
Mack,MB,Detroit,GMC,Yanmar, Isuzu, and more

What type of kit are you looking for,
Customer: replied 3 years ago.
I have a john deere 755 compact tractor. I purchased it from a man that knows nothing about motors. He had a diesel (( I mean a parts changer )) come in and take the head off and removed the pistons. Then the tractor stayed in the weather for about 3 or 4 years. The hood was down, but the moisture still got to the engine.
This is a Yanmar 3TNA72UJ, 3 cylinder diesel. I'm sure the crank is gone. I will have to rebuild it. It seams the only place to get parts is at the John Deere dealer. I just as soon as look for another tractor. Any help would be appreciated. Thank you.

Good evening,

don't give up on this as yet,
i have done engines that laid out in weather , for several years
You can have the crank Polished, or cut to .010 under size
cylinders honed , this all does not seem like a big deal to , me
But I am a engine rebuilder ,
I can walk you thru things to do, if you so choose, and keep the machine Original

Customer: replied 3 years ago.
I am going to pull the engine this weekend and check it out. One of the jernals on the crank look pretty rusty. That's looking down on it from the top of the block. I needed to know if there was a another source to aquire Yanmar Diesel parts. Thank you.
