Tractor
YM226D
YM336d

loader hose busted and tractor ran out of hydraulic fluid or got real low, guy fixed hose and filled up with hydro fluid and now tractor barely moves..runs good, but just creeps slowly in any gear

What could be the issues?

I am looking at buying asap and will replace my ym226d



The YM186 has been sold

The hydraulic hose on the loader should be a different hydraulic pump than the trany even though they share the same oil sump. With that said does the loader work ok now? I am thinking there could be a dirty screen now or even an air pocket in the PS clutchs???

You know you are fast becoming a used Yanmar dealer dont you? We will be calling you Smoodys Tractors! haha

Yep, maybe it stirred up the dregs in the bottom. That would be where I would look first. We are bound to get some good deals from you once you open up. :D :D

I would be worried that there is something amiss with the Powershift pump or clutches, maybe burned/worn from running out of oil and slipping. I don't know how to isolate that as the problem, but it seems like the trouble has to be forward of the main transmission, at either the primary clutch off the flywheel or in the Powershift mechanism. I think the main clutch would have been unaffected by the loader hose breaking, nor by being out of transmission fluid.

The good thing about that tractor is its a US model and he may well be able to buy all the parts he needs from a dealer but I am just guessing on that? I bet it doesn't need much just my gut talking I may be full of it though...

I would probably buy it in a heartbeat if it was in good shape even knowing it has a problem like what this could be or not. That sized tractor is a perfect piece of equipment for small guys operation up to farm use you name it that is a handy sized machine! :thumbsup:

Just got in from checking it out...

Here's the deal:

Good
It cranks over and runs fine
no smoke
all fluids were clean and at proper level
Has yanmar loader

Bad
Guy said 4wd doesn't work
The front hubs have been hacked to use a standard size truck rim
The tractor does not move forward or backward but a few feet.
Missing power shift knob on dash, had pliers on it to shift.lol
Some damage to from corner of hood

I dunno..guess a running 336 engine and loader alone would bring 2000..I can get a pretty good deal on this one..

I would spend the time and check out exactly what the 4wd needs and the front hubs. I think once you found some 8x16 wheels/tires could be (wishful thinking???) be made back to OE.

Hack is a word I use for bad things and take it at face value when I hear it so maybe its worse than I imagine? The screen maybe being plugged and you finding it would surely make the price go up just guessing just how people are haha. Hood is just metal fix it like a fender pound it out bondo it prime and squirt paint on it sounds easy when you say it like that. ;)

Looks like they welded on the hub to get it to fit a standard tire..if I buy it it will be to sell..its not as good shape as my 226.

Could it just be air trapped? Maybe I could get lucky. What would it be worth in worst case needs front end parts aand tranny..I see $$$$$$ in those type repairs.

I haven't purchased..got to think on this one..lol
 
/ Need fast advice on ym336d #12  
Uh, wow. Just...wow. It looks like they used the ends of a full-floater Dana 60 and welded the drums or something onto the hubs, then used only 3 lug nuts to "secure" the wheel...

The hood looks to be there and the tin looks in decent shape apart from the damaged corner. This is one of the times where I'm tempted to say the mechanical aspects of the tractor are much worse than the cosmetics.

Honestly, unless I wanted something from it for another machine, or it was so stupidly cheap (a couple hundred dollars) that I couldn't help myself, this is one of the few I'd pass on. The things that seem wrong are all expensive and complex (Transmission, front axle and drive mechanism) to repair. On top of that, the front end situation is just unsafe to me, and I do all kinds of stupid stuff. I wouldn't want to sell it, because I think it's unsafe. I for sure wouldn't use it to replace another machine like your 226D, which I really liked using and worked well.

The loader looks to be a good one, and the engine has some value. Otherwise, I honestly suspect you'll be money ahead to avoid repairing the front end properly and just buy one in reasonable condition to start with. It is almost certainly worth some profit parted out; I just hate dealing with individual items and that many buyers.

The troubles I see with the tractor are not the deferred maintenance or neglect sort of problems I love to see when I'm looking for a bargain. These are deliberately abusive, unsafe woes. Nobody accidentally, negligently, or lazily scabs outers from a fullsized American truck onto the front of a Japanese tractor. That level of ambition to me either means they are competent and know what they are doing (In which case the 4 wheel drive would work, the shifter, which is really a mega-strength of the Powershift machines, would be easy to use, it would drive, etc), or else they are such knuckleheads that they don't even know what they are doing is stupid and unsafe, so create hazards where none need be, and endanger all future operators of the machine, in addition to fouling up their own equipment unnecessarily. I don't think this work was done with wisdom, obviously, which leaves only bad alternatives.

If you buy it, I hope it works out well for you. Domush did a fine job getting his abused 336D back in working order, so it certainly can be done with enough time, determination and money.

Did you use just hydraulic fluid? or hydraulic/transmission fluid? Powershift has to have hydraulic/trans fluid. Don't know what affect straight hydraulic will have?
 
/ Need fast advice on ym336d #14  
I don't know what the problem is ,but my bet it's not trapped air in the hydraulic system

284 has a way with words. Digest what he said and the decision will come. :thumbsup:

$1200 bucks....but I sure didn't know the front end was a hack job when I made the statement to replace my ym226..that's not happening. I doubt I bite, I guess loader would bring $1200...unless I can find a replacement frontend for it from a junked 336..

Re: Need fast advice ...
How's this? NO. :D

There's no hope of restoring that mess to usable condition at reasonable cost. $1200 before you even tow it home is way too much. This Yanmar has been beat to death, it has reached the end of its road.

284 said it all, more elegantly. You are looking at considerable odds that the transmission is unfixable, you already know the 4x4 is broken, The tire$ all need to be replaced, and I suspect there are many unobtainable hard parts hacked or missing. Forget restoring it.

It's worth some $ for parts, to disassemble and resell if you are into that sort of thing. (Probably the engine and loader are the only parts that would sell). The front axle and transmission seem unsalable.

I think this one is worth zero as a restoration prospect and likely less than $1200 as a parts tractor.

I think wow says alot, this guy needs alot. The front axle does resemble a gm wonder how that happened,also the loader looks like its been modified,Keep your money close at hand on this one

I took the advice of you yanmar veterans and passed on it. Thanks for all the input.

And I sure don't plan on being a dealer...there is a large amount of yanmars in my area lately and people are giving them a away..this is just a hobby I wish I could collect them all!
 
/ Need fast advice on ym336d #20  
Agree on pass on this one if you are not interested in a re-builder or a parts tractor.

However I see some value if the engine does run well the loader appears to be in working order and back tires hold air. The front hubs intrigue me. :laughing:

I think like 284 they were either pretty decent fabricators and know what the real problems are and was a working repair (albeit dangerous it took some doing) or its a hack and weld job from the deep woods and is not long for this world but cant tell from one pic.
