3pt problems when cold

Thanks guys. Yes, it is stored outside, but under cover. I guess you can get condensation on the inside of the gearbox case, and in theory it will drop to the bottom of the case, where I guess the pump pickup probably is. I can't remember ever checking the filter, so maybe it's time. It's a YM1700, so where does the filter sit, and do I need to drain the fluid first?

My Kubota has the metal screen type filter. Ice would get filtered to the point that every thing stopped. Changed filters and fluids and good down to -5 degrees so far. Easy to plow snow when the blade goes up and down.

Yes you will need to drain the fluid. If you beleive it is still good, you can catch it in a clean 5 gallon bucket and reuse it.

Anyway there is a small triangle shaped cover-plate with 2 or 3 screws holding it to the bottom of the transmission. Take it off and the filter-screen lies behind it. Clean it up with deisel fuel if its not got holes in it and reinstall (its designed to be reuseable). This plate is sometimes on the side of the transmission on the bottom of it, under where your left foot is while driving or on the front part of the transmission sump, i beleive?

We Run ATF (automatic transmission fluid) in all our Yanmars, and they run good in cold weather, even at start up

Ernie's testimony was the final deciding factor in my decision to switch to ATF. It improves the cold weather working characteristics greatly and does not seem to hurt warm weather operations either.

When the Yanmars arrive from Japan, almost all the power shifts have ATF.

They are always nice & clean inside and the fluid has high detergents to keep everything clean.
Just don't leave your tractor outside in the rain and you should be fine for a few years with the ATF.

Thanks guys.

One last question, if I may. I want to replace the fluid, so how much does it take (YM1700)? I'll get down the JD place tomorrow.

 

[normde2001]

Buy 5 gal. and fill it up. Why are you going to JD, (2X the price)?

i have also just changed a YM14 to ATF to cure slow shift problems in powershift. no more cold or hot problems to speak of.

This is a good subject for me to pay attention to as my hydraulic system is inoperable in very cold weather until the tractor is warmed up for at least 20-30 min. I'm guessing that in my case, the fluid is a heavier grade which works well in the summer but not so much in the winter.

Could it also be possible for water to enter the hydraulic systen through condensation? Just thinking if the tractor is stored outside, the environmental extremes may make this a possibility. But I could be way off, as this is just a random guess. Probably not, if the transmission/steering/hydraulic system is full.

Perhaps some of the more scientific members of the forum could weigh in on this, as it seems to be a common enough problem for many to benefit.

you will get cond; but if you run the tractor for a long time this will evaporate the water each time then the cycle starts over ''this happens in the engine to you ever seen sludge on the oil stick ,this is from not running it long enough to get it hot to evaporate the water from cond;
