Hello everyone,
 
For a few months already, I am the owner of a MF 12 Hydra Speed of 1968.
I went through the forum and found many answers to my questions.
Today, I wanted to plant my potatoes, but unfortunately the HH120 tractor engine squeezed for lack of oil (unforgivable!). Nevertheless, it still turns (with difficulty) with the manual launcher.
What do you advise me to do in this case?
Can the cylinder be realized?
Where can I find a repair kit?
So, thank you for reading me, I hope the google translation is not too ugly (I do not speak English).
 
Good day and again congratulations for this super site (pity we did not have the same in france).

Ha!  Had to read that couple times to get it. So think you ran low oil and it seized? But, did restart, pulling hard with the "Launcher", that one was best!  Any engine should be able to be rebuilt with proper parts. Getting little harder to find Tecumseh parts, specially pistons, might have to use ebay for sources. Not sure what sources you have for the work or parts overseas. Might just be easier to put in another brand engine, but again, not sure what is over there. Good Luck!

Time to tear down and find the damage.
You won't know until you've inspected connecting rod, rings, and bearings if it is beyond repair or not

I didn't think the translation was to bad at all.  Better than some that are pecked out on a phone with no punctuation, sentence structure and 10 lines in one sentence.  Like MH81 said, time to tear down and find out just what is wrong.

:welcometogttalk:  You should take the engine apart and inspect it for damage.

The translation was actually better than some other languages.

Hello everyone,
 
thank-you for your prompt response.
 
Your knowledge instructs me and I will therefore disassemble the engine to see the case.
 
Have a good day.

Good luck with getting your tractor back in service again! A standard bore piston and rings are fairly easy to find here in the U.S., but finding overbore sizes for the HH120 is nearly impossible and will cost more than I could afford. The tractor needed to be put back in service so I ended up doing a re-power with a 13 horsepower Honda clone engine. It has been running great, smooth, reliable and it consumes half the amount of gasoline.

 

Keep us informed on what you discover. I'm sure we can help more when the time comes. Welcome to the forum.
