Whine when p.s. moves
 

I have a question on an 1862 I just bought. It whines when working the power steering, no leaks, no cavitation, no trans fluid foaming, deck will lower by itself after sitting for a while. Everything is greased, filter changed. I copied and pasted a previous reply, but saw where the valves (? valves) go bad but are not available, so how do you fix this? Substitute valves, live with it???

(From a previous post)
"If the hyd lift goes down its either the valve or cylinder since the pressure has to go to the valve 1st easy way to check is take hoses of cylinder and cap them if it don't go down its the valve we had some issues with Cyclops valves they go bad and from cub they are nla."

My guess is what you hear is a relief valve partially opening

Whine is normal. If it bothers you get a set of head phones.

I have a 1864 that would hurt my ears it was so loud. Filter and fluid change fixed it.

Headphones, lol. Thanks for the replies everyone. I did change the filter, and the fluid looked very fresh, does anyone still think it should be changed?

Unless you are having troubles I would let it roll. Every Hydro I own has
some whine to it. Kinda like a whole bunch a people in this world.

Did you use the correct filter?

Yes, CC 723-3014.

Could air be in the system? Can you bleed the system anywhere?

No way to bleed the system. It may be normal, can you post a video? You would have to post it on YouTube and then post the link here.
