new ym2000 owner

[tex83]

New owner of a ym2000 vn rebuild with vteks loader. I just had a few questions. I lurked on the site before buying this tractor, and found tons of great info. I was wondering if anyone knows where to get a service manual and/or comparable us version of this tractor to get some info. I had a great experience w/ the dealer i bought the tractor from, big red's equipment in granbury texas. Yesterday i was able to put in some time on the tractor, and throughout the day i was getting some leakage out of the gear shifter boot and cannot tell if there was supposed to be something to secure the boot to keep it contained. Not a big deal, but it was after business hours, and my dealer had already closed. I am going to call them on monday. My dealer is wanting $80 for the service manual, and said he would sell it to me for $60, but seems like alot. BTW, love the little tractor. I don't have alot of land, 2.5 acres, but a whole lot of rock and clearing to do. I did not need the loader, and was going to settle for an older gas tractor, but the little diesel just caught my eye and just chalked it up as a big boy toy. Thanks in advance.

Welcome aboard. Hope your new tractor works out well for you. Gear shifter boot is an unusual place to be leaking fluid. Have you checked your transmission fluid level? Hoye is located up at Iowa Park, probably not to far from you. I think most of the on line Yanmar parts dealers will sell that manual for less than $60. Yours is very similiar to the American sold Ym240. Yanmar Tractor Parts

Good to see a new member, and hope you stay around. Id lov to hear how it ends up working out for you, a report from day one. Check your trans vent. It should vent from the top side of one of the axles under the seat, i cant remember which side. Mine has some clear vynal tubing connected to it and run a short length away. If this is plugged it could be pressure building up. That or check the fluid level and consistancy. It could be to thick of oil or to high causing it to be slung up to the boot and running down.

If (as the others have said) everything checks out, you can put a zip tie around the bottom of the boot and it should stop the seepage. My 1900 had the same problem and it was suggested to me to use the zip tie and it has not leaked since. I think sometimes the boot relaxes a bit and doesn't grip the bottom of the shifter grove tight enough. Oil gets slung up there by the transmission gears.

After doing what all the others suggested .You only have on thing that was left out. Of course IMHO. Wipe it off and don't worry about it. Mine will have a drip or two every now and then. And also welcome aboard.

YM240 is the US version of YM2000. Yanmar-USA supplied excellent manuals. YM240 Service manual is intended for a dealer and describes major overhaul. You don't need it. The independent I&T manual (Ebay or a dealer) contains valve clearance, bolt torque, etc info for owner's repairs short of major overhaul.

YM240 Operation is the owner's manual. Operation, fluids and maintenance schedule, specifications, ballasting the tires, etc. This is the one you need.

There are also YM240 Hydraulics and 4x4 axle manuals, intended for specialists.

Senility has hit me again, I see I double posted again. Sorry about that.

If the transmission is not overfilled, check the vent for being plugged. That will be the U shaped steel tube under the seat, on top of the hydraulic valve. The boot works the same as the boot on a brake cylinder, not designed to keep oil in or water out, only keeps dirt out.

 

[Gary Sweat]

In theory (and hopefully by design), oil should not get up into the boot. In reality sometimes it will. I don't know what the special circumstances are that allows it to get there, overfilling the transmission, high speed running etc. Unfortunately once it gets in there there is no way for it to get back into the transmission. I think it would take a long time to fill the boot but it is possible. If oil is seeping out of the boot, using the zip tie will hold it in the boot for a quite a long time.

The shift plate is open to the gears just below it so it may just be the spinning of the gears that throes enough oil up to get past the spring and dome into the boot where it's trapped.

 

[normde2001]

It's pressurized fluid from a plugged vent.

It's pressurized fluid from a plugged vent.

Transmission oil is 6" below the shifter boot. How does the oil get all the way up to the boot? Vent isn't plugged. Put air in the oil fill hole and it comes out the vent on top. Still get a little oil in the boot though.

Here is Hoye's diagram. You might be missing the o-ring that secures the bottom edge of the boot.

I would just add a ziptie like Gary suggested and forget it.

If someone were paying me to solve the problem then I would replace all the soft parts there - boot, ball, o-ring. Also the rollpin that secures the shift lever to the plastic ball. Total maybe $20 in parts.

On my Yanmar that 75 cent rollpin is the only part that broke since I bought the tractor in 2003.

I can see how the O-ring would act the same as a zip tie. Just needs a little pressure to keep the boot sealed in the groove. I've had mine apart and still can't see exactly how the oil gets up, past and through the ball but it does occasionally. Never very much but just enough to wet the top of the shifter housing. Maybe when everything is new it's tighter.

Well, the oil was slightly overfilled. And it only started coming out after a couple of hours of working the tractor. checked the vent, don't see any stoppage. Put a zip tie around, cleaned up, and will find out next week if this fixed it. Thanks everyone. And just discovered hoye parts, good find. Moved alot of dirt and rock with it, and am very happy w/ the little machine.

 

[normde2001]

I wouldn't worry about a little dampness. If the vent were plugged it would force oil out the shifter.
