bucket drops

Yeah, but then it just extends easier since the cyl holds a less complete vacuum.

Yes, I'm in agreement.

Does your theory suggest no one has to replace the piston seals anymore.

So why are people replacing seals, just for the he** of it.

I'm just saying.

Someone replacing piston seals for a loader drifting down overnight....yea, must just be for the he** of it, or someone gave them bad advise.

When piston seals are shot, the loader still holds, but you would notice a lack of power. Cause when trying to lift, Pressure is applied to the base end of the cylinder, and the rod end is opened back to tank. So the pressure bypasses the seals, out the rod port, and back to tank. Thus it is hard to develop full pressure, and the loader lacks power.

But when the valve is in the neutral position, The cylinder "should" be isolated if the valve is good. And its NOT GONNA DRIFT DOWN even if the seals are totally gone. It says something just like that in the article YOU linked.

With bad piston seals you will see very hi pressure develop in a cyl holding against compression forces after a lift. In a valve centered position the seal leak allows the pressure to equalize on both sides of the piston. The net piston area is now the rod cross section. ... If youre experiencing repeated popped lines in transport of a load check the seals.

Update........ Dealer did testing and found deep gouge inside one of the bucket rams, replaced ram and says its holding now.
Time will tell if they are correct.

So the dealer did not fix the problem at all and does not know when part will ever come. Have returned it for refund and bought a Cabela LM35H. Twice the tractor better more bells and whistles and only a couple grand more. The plus really is NO computerized crap on it.

Will be interested to hear how the Tong Yang Moolsan company does for you.

They have been making agricultural machinery since way back in 1968 and have been selling their products in the U.S. since 2004. Look out JD, CIH, NH and Kubota, TYM is sneaking up behind you.

Sadly it seems that JD has gone the way of the car manufactures, Deny that there is a problem till someone gets hurt. the family has had JD tractors for more than 5 decades and yes they are older models but solid work horses with simple care. What I found with the new JD I purchased is lack of honesty in the dealer and the corp for the product.
Trying to pass along the excuse that it falls within JD spec's is just wrong. If they wish to build unsafe equipment, That is on them but I don't have to buy it or their excuses so maybe its time to give the other companies a chance.
