3-Point Hitch leaking down

[YanmarFever]

OK right i reread a previous statement of yours and See that is what you said. :confused2:

But his seems to stay with valve closed so that means there is a problem in his 3pt valve under the seat. Either a cut O-ring or trash stuck in there or just bypassing somewhere.

Clem,
Yes, it sounds like his problem is with the valve.:thumbsup:
You can get a parts diagram off Hoye's website and order what you need there

This is why you had me worried. I have a similar problem. Which at this point isnt a problem, there is no t a problem holding any implement up or using one, just when i cut it off it slowly decends. I bought all the little things i thought could be wear items in my last order and just waiting for a time to do it. I was thinking that you were saying my piston O rings were bad. Not a big deal i would fix it still but i have to place another order, and i was sure my problem was in my valve! Its liable to be a piece of trash in there and nothing else i just have to tear it down and see?

Clem,
Sometimes, its just an old O ring that has broken down over the years.
Once you fix it, it will work like new again.

Im sure thats all it is, i got the packings a few o rings and new dust/rubber boot thing. Like i said, im not to worried aobut it as you cant tell unless you leave an implement up and shut tractor off, which i only do to see if it gets worse anyway and your not suppose to do it anyhow.

this was in my case, just replace the o-ring and been working great since,
although My lift problem wasn't due to it not staying up.... it was that it wouldn't come back down so a bad O-ring can cause problems both ways

I went thru 3pt hitch issues this summer, and since most of the work is in taking it apart, I'd suggest to buy new seals for the valve and cylinder and replace all of them at the same time.
The last thing you want to do is get the cylinder done and have to go back in a month from now to replace another seal.

The parts diagrams have all the sizes available, you can probably get them locally and save on the shipping.

I have a ym1500 and the 3 ph leaks down , I closed the 3ph lock valve and it holds. So what needs to be done to stop the leak down when the lock valve is opened in useing the mower?

Unfortunately, the valve is not really rebuildable. You can replace the seal at the end but it is just a wiper and will not hold in the oil. There are no other internal parts that are replaceable. The shaft seals just by a very tight machined fit to the housing.

Thanks,

This is a valve problem, you dont need to take the whole thing off for that, just the valve from the hydraulics.
