Buying Advice Yanmar 240d questions

[WYdirt]

Hello been lurking for a while & you all have caused me to buy a new to me Yanmar! I have purchased a Yanmar 240d (pictures added) after following all the wisdom reaped from this forum! My question is this... I have purchased the only Yanmar 240 I have ever seen with the exhaust and air filter on the same side of the engine. Is this an odd ball or have others seen this as well? What do you suppose the brackets on the front of this tractor were used for? It has 780 hours (or 1780/2780/... who knows) but it is really good shape overall. Is it OK for the filter and exhaust to be on the same side?

Never seen one like that - and I've owned my YM240 since 2003.

The engine # id plate by the starter should say 2TR20A-X or maybe a different suffix. What do you see?

The intake manifold on these is cast integral with the valve cover so I guess it would be simple to have that as an option. I wonder if he repowered with the similar marine engine or something. I think that air filter is the same one used on the left in the final year of production, 1981, 'Level 4' in the parts manual.

The seat looks original so it probably is the first 780 hours.

Can you post a photo with hood open and looking down on the cylinder head?

And welcome!

I'd say it had a snow blower or something on it at some point, maybe the hydraulic levers on the other arm up near the steering wheel? I'd say 780 hours too, a very tender and gentle 780..... It's in great condition.

Welcome to the forum. :welcome: According to Hoye the 240 came with to different filter styles, standard and the one you have. AIR FILTER- ^ STANDARD STYLE ^: Yanmar Tractor Parts AIR FILTER: Yanmar Tractor Parts

Looked in the parts manual and surenuff,optional air cleaner looks just like yours. Sending you a pm.


Beautiful country there. Looks like you might need that snowblower come winter.

It appears someone has taken very good care of this old yanmar

California,

Thanks for the reply! The engine ID plate reads 2TR20A-X, But looking at the service notes that got passed on to me, the engine serial number is not the same as what was referenced in the service history (but the tractor serial number matches the what has been wrote down years ago). So I DO believe it got a new engine at some point, but cannot find ANY application that has the exhaust and intake on the same side of the head. This might be why I also have a tote full of spare parts, injection pump, injectors, exhaust & intake manifolds, water pump,a bunch of fuel lines, nos gaskets, bolts & pins, fan, fan belt etc, etc.

It looks very clean & everything but this air cleaner sharing the same side as the exhaust looks right (except a very welcomed oil pressure gauge & weird mounting bracket on the front). Here are some pictures of the engine.

Snowblower, do they usually have multiple mounting holes like this? Or did they a long time ago? I have been searching all over for a picture that shows a similar mount & of a Yanmar that does all it's breathing on one side .

Thank You Winston1! I will be getting the air filter from Hoye Tractor (another gem of information I have reaped from reading & lurking on this forum). Those pictures were taken on the mountain pass about 2 hours away from home after I bought it Thursday. I live in the high desert in Wyoming 1 hour away from anything this pretty I have sure had it with the snow this year though, woke up this morning to another dusting of snow (it was 50ish yesterday :irked . That's one of the main reasons behind the purchase of this tractor, tired of shoveling a 400' driveway & mowing 3-4 acres on a small riding mower. It will probably never snow here like it did this year again (we blew out all records), but I will try & be prepared if it does! Thanks again for the PM!!!

Been lurking on this forum for quite a while & looking for a clean old Yanmar (love their simplicity & rugged design), this one exceeded my expectations!

The more I tinker with it, I am amazed that it is at least 36 years old! When I woke up to snow, I felt bad because I have not cleaned out an inside parking spot for it yet (today's project). It will be getting a spoiled life from here on out as well..... These tractors have a personality that you just don't find in anything new & who has 20K to throw down on a small tractor & get the bonus of hassling with emissions, computers and a bunch of other junk that doesn't belong on a tractor! I grew up in Missouri mowing with 8n & 9n Fords, and this little guy reminds me a lot of them with the added benefit of 4WD!

You're going to love that thing. Yes they do have a personality. Just my imagination but I wonder if the original Japanese Yanmar tractor owners felt the tractor was a sentient member of their family like the water buffalo that their first tractor superceded.

That is the ordinary intake manifold/valve cover, and the undisturbed black paint there further supports that it is a low-hour engine. The air cleaner mount is unpainted, and the hose clamps on that crossover tube toward the air cleaner don't match the oem clamp right at the manifold. I conclude that whoever mounted the snow blower or whatever it was, extended the original U-shape of that intake hose and modified the air cleaner mounting to avoid interference with some new hardware on the left side of the engine. So it's not a Frankensteinmar assembled out of unrelated parts, just a rational modification to mount some third-party equipment.

Mismatched engine serial # and the non-original bolts between engine and bellhousing suggest a replacement identical engine. (Check that those bolts are tight!) The addition of an oil pressure gauge might suggest some catastrophic end to the first engine, but I don't recall ever reading here of such an event on a Yanmar.

'Turf' tires on a 4wd might indicate this was bought new for primarily snow removal, with tire chains. (This seems to work better than ag tires for snow). Do the tires show scuffs indicating chains? And I don't see the rust that is common from clearing salted roads for 30+ years, indicating excellent maintenance or non-urban use.

Do you see any remnants of hydraulics? That mount by the throttle and the adjacent wear on the fender suggest a hydraulic control was mounted there.

 

[WYdirt]

I already do! I agree, these tractors had to make a huge improvement to their quality of life & from what I've been reading almost as reliable as the animals they replaced! The guy I bought it from Thursday got it a couple of months ago from what sounds like a small tractor dealer/service shop that was closing down. He didn't have much history on it besides it was a local tractor around Logan, UT. I could see this being used by maybe one of the ski resorts for snow removal ???

The front tires show some minor scuffing and are worn down a bit, but the rears don't show much wear at all. I think they are all the original tires, as they are all matching Japan made Bridgestones with weather checking on them.
?


The only remnants of any hydraulics is a fitting under the seat that doesn't look original, but I agree, that is for sure a valve mount, but for what.... Snow blade,push blade, or snowblower? How many hydraulic fittings would one of those attachments take, just one? Would love to find the original attachment for the front (whatever it may be)! I do not see any hydraulic remotes either, did these have them?

Thanks again for the help, you all have NO idea how helpful your posts have been that are frozen in time on this forum! What a blessing to be able to research and learn through other peoples experiences with these little tractors!

That rectangular hydraulics block is original on the US Yanmars, doesn't exist on the gray versions. Default is fluid passes straight through and onward to the 3-point lift valve. It can also be configured to send fluid out one of those capped ports and back in the other, to power a loader valve configured in series with this line. (diagram). (photo - mine). I -think- you remove the top half of the block (unpainted in your photo) and reverse it to make this config change.

Yanmar's manuals show using this block as the correct way to plumb a loader. However ... several know-everything posters on TBN say this is impossible, say it will destroy the loader control valve because that valve can see huge back pressure if the loader and 3-point are operated simultaneously. They recommend going to 'Power Beyond' configuration instead.

Whatever, when I replaced my dribbly loader valve I plumbed it the same way I found the 30 year old third-party valve and I haven't had a problem with it. I do avoid using both hydraulic controls at once because I've seen that peg a 4k psi gauge, this can't be good for a system rated 2200 psi nominal maximum.

Confused yet? When I replaced my loader valve I asked for a lot of advice and learned hydraulics seems to have something in common with witchcraft. I ended up just replacing like for like. I asked a lot of questions on TBN and got involved in a very confusing thread. Here's one post with photos that might be helpful, I guarantee most of that thread will leave your head spinning.

Where does that hose pointed toward the rear go? Do you have the manuals to see what does what?

 

[WYdirt]

It did come with the original operators, service manual, some brochures, some pages of the parts manual, other paperwork and a bunch of spare parts (probably off the original engine) ... Winston1 was super awesome & sent me a parts & hydraulic pdf's, now I'm just missing the 4wd supplement!!!! Just Looking at the hydraulic one gave me a headache, I agree with your witchcraft terminology!

I actually read through that thread about you replacing the loader valve a few days ago (after I agreed to buy mine but before I picked it up). It was a very informative and confusing thread that had a lot of great ideas about power beyond locations. I would LOVE to put a loader on at some point, but they appear to be rarer then hens teeth used. I have read about Coldwater up in Oregon that maybe still makes them, and then Koyker but $$$$, I wouldn't mind finding a VN or bulldog loader, but haven't seen any available to buy without having to buy the attached tractor! :laughing:

My block does not have a hole on the side of it like yours, I wonder if you have to get a different one for a loader hookup? There is no hose connected to that fitting behind my block, it is plugged (it's an optical illusion in that picture) that must have been where they had the (whatever) plumbed to I guess, the only lines back there are a couple of air hose lines that somebody has connected to the brake vent tubes, one of those lines is attached to the end of my slow return valve... that one didn't make any sense, I will be removing it when it warms back up. ( i could not find the slow return valve because the hose was attached to it LOL)! The slow return valve (with hose that will soon be removed) is facing forward, I wonder if that is the proper location? The blade seems to do what I ask it to, so I guess I'll leave it for now.

Could have been catastrophic engine failure from something as simple as a punctured oil filter and a tractor that ran out of oil before no one noticed. But seems like it would need to go a long time to blow it or lock it? I just watched a video on YouTube where a guy ran one of those $99 harbor freight motors with and without oil on a thermal camera to show the heat fifferences. After 30 mins the temps were not that different on the various parts of the engine, it still was not blown or locked up, he just ended the video and did a tear down of it to show the wear.

The air cleaner assembly has been moved to it's current location by someone, the brackets are "home made" and the plumbing doesn't match the OEM Yannie stuff. No matter it still functions as intended.

 

[clemsonfor]

That place where the pic is taken is beautiful!

 

[WYdirt]

I would love to be able to find a picture of how it was originally plumbed under the hood. There are no mounting surfaces on that side of the head. I wonder if the big air filters were mounted to the hood in some was originally? Do you guys think I would have to move it somewhere else if I ever find a loader for it? I'm not sure if it would clear everything.

 

[WYdirt]

It is a very beautiful area, crossing the mountains on HWY 89 between Logan & Garden City UT. Bear Lake (the Caribbean of the Rockies) is in Garden City & is an amazingly beautiful lake. Very awesome drive, unless you are hauling something! This is Bear Lake!

You should be able to look at page 57 in your manual and then look under the hood to see where mounting bracket #18 should mount.

 

[WYdirt]

LOL, I must be blind, I cannot see where the mounting point on the other side is, in the parts manual (thanks a million btw!), in pictures, OR in person! I will probably leave it for now, unless I run in to clearance issues later on.
