Buying Advice Yanmar 240d questions

[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?

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.

That place where the pic is taken is beautiful!

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.

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.

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.
