YM 2000, Looking at a very Clean Front End Loader, bad engine

[toppop52]

I found a very clean and nice YM 2000 with 2TR20A engine, that has serious blow by and needs a long squirt of starter fluid to start. Seems fairly common with these. I talked to Hoye and they tell me $350 for refresh parts less pistons. The hydraulics and everything work great, nice seat, paint, steering wheel, nearly new tires. Transmission, clutch, brakes, diff and all seem very solid and the tractor will actually run fairly decent once started. It is supposedly an 80's model, it's red with a white stripe where the YANMAR is. It's 2wd. Asking price is $2100, might get him down a couple bills but he ain't going far. Is it worth a roll of the dice or no?

If it were me, I would do it. That's a couple thousand less than a clean tractor that doesn't need anything.

If ether has been used in it, the ring lands in the pistons are likely shattered. Rings likewise. So budget some money to repair that.

And - before overhauling the engine I would try the cheapskate approach. Look for my posts in this thread. I installed a direct-replacement much stronger starter from a larger Yanmar which cranks so vigorously that I think it would start any YM2000 regardless of condition. Once your rig starts reliably you might decide to just run heavy oil and put it in service as-is, particularly if you only need it a few hours per year.

We've read here several times: don't use ether in the small Yanmars!

most yanmars do NOT need ether and its not a common thing either!! Those are guys that are use to big diesel equiptment.

Also if its a ym2000 its a 78 or 79 they did not make them into the 80s.

If you can do the work it could be a good deal. If it has "serious" blow by I would plan on making repairs and keeping the old starter.

Yes, if you get it make the repairs.You will likely have much more power. Don't know the condition of the loader , New loader is 3-4K. IMO, It would be a good deal

The fairly common thing I meant was blow by, also saw a bunch of slow start issues. Of course you don't read about guys with perfect running tractors, they have no reason to post. LOL

 

[toppop52]

I'm going to look again and make an offer, thanks for the help!

u can get those VN loaders for less than $2k so if that's what it is don't use the $3k figure.

 

[clemsonfor]

oh ok I got ya. I deal with loggers and those guys will run equipment on ether till it catches!!! Like when there starting an old diesel on a cold day they will run the engine on ether till the engine starts fireing on diesel. I have also seen when they change filter and take injectors out instead of bleeding the fuel they just run it on ether till it bleeds itself. Just spray some in there start it and then hold the ether down while it runs till all the air is bled!!!

This tractor is red with white stripe, I'll try to post a pic from my real computer in a fe minutes. What year was red? Anyone know?

 

[toppop52]

Looking at the green engine I think someone didn't like the color and made it red.

 

[California]

Red is correct for a second-series YM2000. Although it should have a white grille. And 2TR20A is the second-series engine.

Early YM2000 was green. But that version had totally different sheet metal - headlights outside, alongside the grille, and the hood hinged at the back like an automobile. Engine was 2TR20 (no 'A'). I don't think there's much difference - dipstick on the opposite side, stuff like that. But you need to specify Early or Late on a parts order.

I think the engine and chassis were your color of green on all Japan-market Yanmars in the YM era.

Don't be misled by my green YM240. US Yanmars didn't switch the sheet metal green to red at the same time as their Japan-market twins. YM240 Late retained the Early color scheme.


I was just looking at your loader. I hope it has a frame that carries stress back to the rear axle. And preferably it should also be attached alongside the engine near the starter etc. Just bolts going upward to the bellhousing aren't enough support.

In fact the more I look, the stranger that 'VEAM' loader looks. I would tear that side to side hard hydraulic line off the first time I drove into a downed tree to move it. (BTDT on better-guarded hydraulic lines - don't ask! )

 

[toppop52]

Thanks, I'm way more familiar with Yanmars in boat, John Deere and equipment than on actual Yanmars tractors.

Boats? This is the same engine as the 2Q marine engine - with obvious different manifolds etc.

As an aside, I found this brochure awhile ago.

One thing jumped out at me: a hand crank for manual starting! I have decided I shouldn't gripe anymore about dead batteries and the nuisance of a hard starting diesel. I would NOT want to hand crank one of these things...

The other thing I came away wondering (and the reason I found the brochure in the first place) was where the zinc anodes install. I was wanting to put them in, if they fit, to my tractor engines and reduce or eliminate the possibility of any corrosion in the radiators. I still think it is a good idea for me, since I run a high fraction of water in my cooling systems and worry about the radiators in that environment.

I have since found anode equipped radiator caps, but does anyone know if the 2QM anodes fit the tractor engines?

As an aside, I found this [2QM20/3QM30 Marine Engine] brochure awhile ago.

Wow! Thanks for posting that. I had never seen a hp curve chart for these. I see that the continuous hp is 20 hp @2600, 1 hour rating 22 hp @ 2800, and 15 minutes rating is 24 hp @ 3000. With a nearly flat torque curve, ie approximately same torque from 1400 rpm on up if I'm reading that chart correctly. That matches my impression of these engines, same torque at any rpm and the throttle is simply for how fast you want to go.

This is a great addition to the common body of knowledge here.


As for the crank starter - I wonder if the manual handle winds a spring?

Asking price is $2100, might get him down a couple bills but he ain't going far. Is it worth a roll of the dice or no?

looking at it i would jump on it even with a buggered motor in it. the engines originally were a horrid green but the sheetmetal is red. my 1500 does not have any reinforcing from the trans crossover to the rear end at all. thankfully it has not broken in half!

 

[toppop52]

I just meant boats with Yanmar engines of all types, most of the ones Id seen were either tiny ones like these 2 cyl engines or the huge yachts with gigantic twin 800-900 h.p. engines.

That's some good info! Thanks!

Looked at it and a MF 234 with a loader, made an offer.
