Just jumping in here , bleeding the system is a waste of time as the system will bleed itself . The reason it turns all the way one way is its loosing trapped oil internally due to worn O-rings and/or cut O-rings during assembly .The steering motor needs rebuilt including the fed-back piston .

Only when it's to their advantage. How there is a double standard banning English signs in Quebec and no law banning french signs in the rest of Canada is a mystery.

If the seat accumulator is bad the seat will be hard as a board to ride..no cushion at all...If you buy a new one they come with out charge,,and if your's is empty you may as well buy a new one, they won't hold a charge,,like a slow leak in a tire..

Hi Tim

Ok thanks a lot for your answer. So I think the one from the seat is good. Smile

They are pricey too,,, the one on the transmission cushions the shift a bit,,a little harder to tell if it's bad.. they carry 90psi of compressed nitrogen in both of them..

I have used A&I accumulators with good results. IIRC they are $200 compared to Deere at $400. You will not here me say much good about A&I parts but These are half price and look identical.

Hello
I am now ready to work with my 4450 and already done some work with it Smile
There are some small leaks on the front axle, that need to be repared.

And my question for the forum is, I am looking forward to repair the air condition. Now I found the specs http://www.apairinc.com/shopping/?model=10829 to fill up the system with R134a (already used in my 4450).
Does anyone have an idea if this amount of "coolant" is right? I also need them in kg so it should be about 1.47kg R134a.

Thanks for every help and as always excuse my moderate english, I hope its understandable Wink

Stefan

Hi Tim

Thanks for your Answer!
I can't do it by myself, so I don't know how much that one can is? Do you know it maybe in kilogramm?

Thanks
Stefan

Small can of 134A contains 12 oz's so 5 cans has 60 oz's X 28.3495=1700.97 grams

You're welcome
Be sure AC system gets a good evacuation to remove air & moisture.

Hello

Today my 4450 is in the "ac- shop" to get the aircondition back to work Wink

But since the last silage work, the mfwd doesn't work correct. I am not able to turn the mfwd off.

What I tried to fix it is:
- Voltage check on the solenoid - ok
- Solenoid check for correct work (with a magnetic tester) - ok
- Valve test dissasembled - ok

So I think the valve works correct when it is expanded. But I am still not able to turn off the mfwd...?

Does anyone have an idea what I can check as next or did I forget something?

thanks in advance Cool

Stefan
