Hey yall! Tools in the description!

[@brianedwards231]

I am jealous of your crisp manual. Many of us are stuck using manuals with 8th generation photocopied pictures.

[@SouthernYankeeLifestyle]

Keep the vids coming man I just got a 1700 and it won’t start so these help and I may want to rebuild too- it’s on my bucket list and this helps

[@MattsShop]

I am, my rebuild video is gonna drop when I get the rest of my parts. Stay tuned.

[@SouthernYankeeLifestyle]

As far as the rebuild kit goes for the engine where did you order it I don’t see a whole Lotta options online

[@AmsterdamCesar]

Again nice vid, Matt!
For me its almost time to transport my Yanmar 2210 from the North of France to the West of France, where she will be doing some jobs around my vacation home, like mowing & plowing.
cannot wait! 🚜

[@MattsShop]

That's crazy man! I had no clue I had viewers in France! Put it to work!

[@OutdoorsinSC]

Great video! Thanks!

[@MattsShop]

You're welcome!

[@brngrofdeth]

Looks sunny there dude! 4 inches of snow here. Can't wait for you to fire it up! Love and blessings from Ontario Canada.

[@MattsShop]

It rarely snows here. Cold but sunny. I can't wait too. Hey from the USA.

[@jimbop101]

AWRIGHT...Getting close. I'll prob start my rebuild after the holidays. I'm sure I'll be referring to these vids often. Thank Matt

[@MattsShop]

Let me know how it goes! Make sure you get a manual. It helps. You're welcome!

[@eddieroberson2013]

Thank you man

[@MattsShop]

You're welcome!

[@myslash09]

Could you tell me where to get a manual for my yanmar ym1730d thanks enjoy your videos

[@JagReport]

My tractor does not have the notches on the pulley. It’s kubota B6000. My tractor would barely start and sometimes wouldn’t start. I tried adjusting the two nuts on top that are attached to the decompression lever. When the nuts were all the way in, the exhaust was putting out white smoke and engine wouldn’t start at all. I adjusted them by pulling them out a little and tightened the small nut around it for both cylinders, the tractor runs great now, no white smoke, and it starts even faster than before. It even starts on idle without giving it more diesel. I am concerned, did I do too much compressions and is there a risk of blowing the engine out? Or am I good? Any ideas or troubleshooting will help, thank you.

อยากทราบว่าคุณซื้อ ปลอกสูบ ลูกสูบ แหวน และอะไหล่ต่างๆจากที่ไหนครับ

[@user-eb6yd5jg4m]

Where did you get the engine service manual? Do you want to sell your old manual and liner/ring compressor tools? I have a YM2000B

[@MattsShop]

I got my printed service manual on eBay for the Yanmar YM240 the American version of the YM2000B. I don't want to sell the tools, because I plan on rebuilding more Yanmars.

[@rottmanthan]

how many hours are on it?

[@yenomhsac09]

how much should this cost to have done? I have a ym1610d

[@MattsShop]

The problem is no one knows how to work on these old Yanmar tractors. Maybe $150-200.
I did all the labor. I paid $100 labor plus parts probably $150. So $250 total to rebuild the head.

Красне дякую
