How to by a used Yanmar

[clemsonfor]

yea forgot the valve cover stamping Cali. Also the cast # on the trans by your left ankle while seated, i didnt think that told you model # i was thinking it was something like (well maybe model #) and unit #??? Heck i dont even remember what it says now?

But As for as a 2cy engine on a 3110 anything i guess was possilbe. Its not common but supposedly the VN refurbers overseas have been know to do stuff like this. I guess they would of had to match it up with something like a YM3000 engine or so to keep it in line with the overall tractor size, i think this is a different size frame than the 2210 has so i dont think that would work.

This is what I have that it should have:

Well now this is interesting. Tractor #1 turns out to indeed be a three cylinder after all There is a third fuel line there you can't see in the picture I posted from CL, I guessing due to the lighting when it was taken. However, the engine tag says it is a 3T84T-H, AND the model number forged into the transmission housing is "YM3810". No mistake. Those two pieces of information seem to be consistent with this being a 3110 hood on a 3810 tractor right.

In any event the tractor started right up no problem. I ran it around the yard through all 4 Power Shift gears in all 4 ranges and "Creeper". Reverses seemed to work ok too. Brakes worked on both sides fine and I could pivot the little tractor on a dime. All the fluids looked good (maybe too good) and the lift seemed to work fine as well. Lights and turn signals all worked. Nothing looked out of place either. That is there didn't seem to be anything slip-shod about the tractor. Everything looked to be in order.

Also, to me it sounded right. Like a little diesel would sound to my mind. The transmission did seem to "whine" some though. Like an old Hydrostatic lawnmower. Also, changing gears in Power Shift seemed a little jerky but maybe that's normal. I'm uploading pictures and a video now and I'll post a link ASAP.

What y'all think?

Ok here is a link to a photobucket album that has some more detailed pictures:

Here is a video of the tractor running. Puffs a little black smoke when I cranked the throttle but I think that is alright. The sound is pretty good. You can hear the engine and the transmission anyway:

The trans on those is supposedly notalbly "crisp" and hard from what the vets say. I never driven one though.

BUT if you look at the list of Engine ID that scotty posted that is not the correct engine for a 3110, may be a 3110 on another tractor? Im to lazy to look up the engine for the 3810 though, but im thinking (help me out Kenmac and Cardoc) isint the 3810 just a turbo'ed version of the 3110? CD and Ken are good on this line of tractors as they both have them. If it is indeed a true 3810 with wrong sticker it may be a good deal?

Well there is another thread on here called "Yanmar Models" (which Scotty posted a huge list in) that I believe lists the 3810 as having a 3T84T and the 3110 having a 3T84D. Maybe they took the turbo off of a 3810 and slapped a 3110 sticker on the hood. The back end of the tractor is definitely stamped (forged) with the YM 3810. Just in front of the clutch where the steering box is are the numbers "0624" if that means anything. If the difference between a 3T84T and a 3T84D is the turbo that might make sense. I sure didn't see anything on the engine that looked remotely like a turbo.

Sounds like a 3810 with the turbo removed (or engine replaced) and a new hood decal. If that's the explanation, I don't see why it would be a problem.

Was there an engine model tag showing horsepower, on the engine? Below is the tag on the valve cover of my little Yanmar which was built about the same time as a 3110.

Powershift - at least on my little 18 hp Yanmar - is 'crisp'. Each shift is similar to putting an AT into drive at a fast idle - or maybe a little more harsh than that. This isn't a problem just a 'feature', since Powershift works exactly like an AT that doesn't have a torque converter to soften the shifts.

My well worn Powershift has more than a little whine in high range, like an old overdrive and nearly as noticeable as an old jeep. Hopefully this 3110 sounds nicer than that. Again, I wouldn't worry so long as it sounds normal for a compound gear set.

Yeah here it is though it is in Japanese of course. You can get the gist however. Looks like it says 31 HP @ 2800 RPM, 1.4 liter.

Well i think we figured it out. it wsas a 3810 but has a 3110 motor in it. but with the motor being the same except for a turbo u shoulnt have a problem at all with it. and yep that was the tag i was hoping you would see!
