New Yanmar owner - kinda sorta

[Goldchaser]

New to Yanmar, not new to tractors. Just never owned one as small as this one. YM155D. Was given this one by a friend. Been sitting for a number of years. Actually have been surprised at the good condition so far. Only a bit over 460 hours on it, no rollover. Have not yet gotten it running. Between waiting for parts to arrive and waiting for manuals, its been relatively slow process. Had to purge the fuel system due to water in the tank because of a cracked and sun rotted fuel cap. Changing out the oil and tranny fluid as the filters and other items come in. Purged the cooling system. Replaced the battery. Verified that it will turn over. However current battery does not have the strength without the charger hooked up. So am looking for another battery as soon as I can to get some CS power.

Otherwise, once I get the new cap and catch filter, which should be here in a few days, I can get fuel into this thing, purge the lines and see if I can start it.

Looking forward to getting this going. It comes with apparently factory installed FEL. Not an addon. Am guessing, from the serial, it was built around 1980, perhaps a bit later. My friend was the original owner, so I know the hours are correct and know the history. What happened and why it sat for years is he had used it. Parked it and it was sitting for a couple of months and he went to start it and couldnt get it started. Left it sit for a while longer, still couldnt get it started and pretty much gave up on it. Never took it to anyone....dont know why, he just ended up getting another one, a little larger and this one sat.

Will try and post a photo of it. Right now the bucket isnt attached and I am in the process of replacing the hydraulic hoses that go to the FEL. They were/are cracked pretty good so figured it was better to do that before I attempted to start it. Am also replacing the glow plug as a precaution. Prob isnt necessary, but I got one at about a 1/3 normal cost so it was worth it.

This tractor is worth putting some bucks into since it didnt cost me anything in the first place, except some time.

Only other thing that I am concerned about is the possiblity of the clutch sticking or being stuck. I know this is a possiblity after sitting for a long time so if anyone has any ideas about how to check it before I go ahead and start it, would be appreciated.

Paint is in poor condition on the body, some rust showing. Yanmar green, of course. Frame is black, and the paint on it is pretty good.
Seat, rotted away. Only thing left is the pan. So looks like I will be adding a cushion from the house for now, long as the wife doesnt catch me. <laugh>

The third photo below is one, not as clear as I would like, of the fuse panel underneath. I have not seen anything like this. There are no actual fuses. Wires come up to screws on either side, and between are wires that lose to be fuseble type of material but is open to the air. Never seen anything like it before. Any thoughts from anyone?

Nothing wrong with a free tractor!

To check the clutch see if you can put it in gear and have someone else push the clutch in and see if the tractor will move. If not its probably seized. I've heard that if necessary you can SLOWLY drive the tractor up to an immovable object and at the lowest speed possible push the front of the tractor against the object with the clutch pedal pressed in and it might break it loose. There is probably a safer method though.

Are you sure that that fuse box isn't actually a distribution box?

Good luck getting your tractor up and running!

Well, wont be quite free by the time I get it going.
Will check the clutch as you suggested.

As to the possiblity of it being a dist. box, I dont know. Its right where the fuse box is supposed to be on this model unless the fuses are somehow hidden underneath it. Just never seen anything like this before. Will try to get a better photo of it later and post it.

Had not figured it would take this long to even try to start it but it seems like every time I think I am ready I find something else I need to fix first and then have to wait for the part to arrive because the local dealers like the JD are pretty much useless and have to order any parts anyway. I gave the local JD dealer a couple of parts to order and 10 days later they still hadnt come in. So placed an online order with Howe Tractor yesterday and expecting them Tuesday morning. Thats the kind of service I like.

Anyway, thanks for the suggestion with the clutch. Will let you know what I find.

You did good!

I have essentially the big brother to that tractor and its loader.

My loader has the same control valves and structure, and a builder tag inside the left pedestal that shows it is a Great Bend 20. Great Bend was in Kansas then, and later was sold to Bush Hog who today don't have any manuals or parts lists. But it's built out of all generic stuff supported by any hydraulics shop.

I left the ratty hoses on mine. My experience is that I rip off about one hose per year moving snarled up downed trees, plus a couple of times I've discovered one bulging indicating it is near its end. One had been too close to the exhaust for a couple of decades. Just put your good new hoses on the 'lift' circuits so you can get the tractor home if an old one breaks!

That's the fuse box. The fuses are tiny bare wires. I've read these were also used on early VW, but I've never found any in the real world. I think the dealers who post here can provide them. They are attached with tiny screws and tiny washers that are too small to grasp as you remove them so they inevitably roll across the floor, a real frustration maker.

I put in fuseholders for glass fuses in place of the fuses on mine. A better solution is a fuseholder for a modern blade fuse in place of each one, or better yet, replace the box with one that takes blade fuses. But if the fuses are good don't mess with them!

I think the I&T shop manual covers that model. Its available from the dealers who post here. Also from ebay and Amazon, but verify those are current editions.

I think that external air pre-cleaner identifies that as the final series of the green US Yanmars, about 1981~83??

Thanks for letting me know about the fuses....urrrr....wires... whatever. That has got to be the strangest setup I have seen though. I think the first time I blow one of those I will convert it to regular fuses. Whether the blade type or the tube, dont matter. I usually have plenty of both in the shop with all the varied vehicles I seem to accumulate.

Looked at your photos of your 240D. Yep...definately the big brother of mine. Looks like it too.

I dont think your hyd lines could be any rattier than the ones on mine. See below.

I am also going to have to ask my friend about the PTO cover, which is missing. Looks like he removed it to add some kind of bracket to the toplink bracket. Looks like he was wanting to extend the length of the toplink for something. Added the photo below of the backend of the tractor.

I am looking forward to getting this running. Had been wanting one for a long time and then this one just fell in my lap out of the blue. And its going to come in so handy.

I replaced the one on my YM155. NAPA

Wanna bet?

I stand corrected.

You got the box at NAPA? Hmmm...got several of them within 20 miles or so. Worth checking out for sure. Likely will just buy it, then when I blow the one on it, will have quick fix. Thanks.

I saw your post in the other thread. The durability of these Yanmars is amazing. My (non Yanmar) loader has the expected evidence of 30 years use but the tractor itself seems timeless. I have no idea if the 041 hours showing when I bought it in 2003 was 1041 hours, or another thousand or two. Nothing has worn out or broken, aside from my own user abuse such as ripping those hoses off plunging blindly into a downed tree - hardly a reflection on Yanmar!

I think the only things that needed renovation when I got it were the Thermostart module, the seat and the rubber bumpers it rests on, and the ignition switch. (The previous short term owner had replaced the radiator and starter). I spent a couple of weeks tinkering like you are doing but that was all normal scheduled maintenance that had been ignored for years - loose wheel lug bolts, replace fluids & filters, etc.

I keep spares in the barn for those pictured loader hoses!

If your loader is the same, get some spares for the little hydraulic elbows where the hoses go into the curl cylinders. It's easy to lift rubbish, tree limbs etc, and discover all the weight is bearing on those elbows. I've broken two of them.

Here's what broke them. I'm clearing berry bushes that are choking an old apple tree. Occasionally I snag a limb.
