ym2000 questions, new owner.

[callais]

I just bought my first tractor, a yanmar 2000. Quite happy with it but a little confused about the first few minutes of run time and the last few minutes of run time. What rpm's should I be set at and for how long during start-up and then for cool down? Can I safely drive the tractor around during warm-up and cool down? /forums/images/graemlins/confused.gif
Also, my temp light does not work, can I easily install a water temp gauge instead of just a light. Thanks in advance for any help.

Callais,

Welcome, from another new owner!

My first tractor is a YM240. This model is a YM2000 adapted for the American market back when Yanmar had a US dealer network. The only notable difference is an overrunning coupler built into the PTO on the YM240. Also the throttle lever is push rather than pull to accelerate, per American custom.

I joined TBN in January and immediately started asking all the typical beginner questions. You can find a few answers if you read through the replies I received to my questions.

In answer to your question re warmup rpm, scroll down to 1/29/04 in this Yanmar forum and see the thread 'Lowest working rpm?' Several experienced owners replied, and Jim (Jim's Tractors) even scanned and posted some pages from the owner's manual.

I have an answer to your question on the high temp light: It probably is ok. To test it: Turn on the ignition switch. The other two warning lights should glow. Go to the top front of the engine and slightly unplug the cable at the temperature sensor so you see a little bit of bare metal on the sensor's connection post. Run a jumper wire from that bare metal to ground. This should make the temp warning light glow.

If grounding the wire to the warning light doesn't make the light glow, test the bulb by swapping it with one of the other bulbs that you just saw working.

If the bulb is ok but it won't light with that jumper in place, look carefully at the sockets for the three bulbs. The ground wire attaches to the oil warning light with ground bridged by a brass blade to the second bulb (alt) and then bridged by another brass blade to the temp socket. The 3-lamp assembly was corroded on mine and was hanging loose with its mounting tabs missing when I bought the tractor, but the bulbs still lighted properly. I installed a good used warning light panel from another Yanmar.

If you really want a temp gauge - I read that the temp sensor is screwed into a British standard pipe thread hole so you need a British to metric adapter to screw a standard temp gauge sensor into that hole. For myself, I enjoy the absolute simplicity of the way Yanmar designed the whole tractor and I haven't added any options.

Welcome to TBN.
You'll find more Yanmar owners and dealers here than anywhere on the net.
It's very easy to add a water temp gauge to the YM2000

Thanks for the advice and help. I read through most of the posts, lotsa helpful info here. I will go ahead and install a temp gauge this week. A few quick questions, is it safe to use a 5 foot disc harrow with my ym2000? Has anyone used ( and felt comfortable) with a tilt meter? thanks again .

The only thing with installing the guage is I think you will need a metric fitting to install it to your engine block. ??

On the YM1700 the only metric adapter needed was for the oil pressure gauge. Water temp sending unit fit with the adapter supplied with the gauge kit.

I just bought a water temp gauge and metric adapter from the sunpro website (garage sale). I will also order a tilt meter tomorrow from www.tiltmeter.com. The more info I have while on my tractor, the better off I feel.

When I first bought my YM1610, about 15 months ago, I also bought the Tiltmeter because I had some areas I mow where I felt uncomfortable. After 50 some hours using my tractor, I have more of a feel for how stable I am and have been over the same ground repeatedly. The result is that I don't look at the meter as much but I still think it has value.

On a different point, The cold weather seems to have left us here (Today's high 79`) I am happy to say that last week I went out to my tractor for the first time in two months and it fired right up with no hesitation on the first crank. I drove around my property just to remember how it feels.

I'll be mowing in another three weeks. /forums/images/graemlins/cool.gif /forums/images/graemlins/cool.gif /forums/images/graemlins/smile.gif /forums/images/graemlins/grin.gif

Make sure you get the adapter CP7574 beacuse you need the M16 X 1.5 to 5/8" x 1/8" NPT adapter or "bushing" to mount your new mechanical sender. (The British Stasndard Pipe that was mentioned earlier is needed if you replace the oil pressure sender.)
I was able to find one of these bushings at a local parts place /forums/images/graemlins/grin.gif- it was labled as for use with mounting temp sender in Japanese motor....so it must not be too uncommon of a bushing. /forums/images/graemlins/confused.gif but it did take me a while to find it. /forums/images/graemlins/smirk.gif
Good luck

I bought the adapter kit from sunpro which had the correct adapter. Water Temp gauge works great. Thanks for all y'all help. /forums/images/graemlins/grin.gif
