T all who have ventured into hydraulics...
A year ago I bought a 1996 Kubota KX75UR grey mkt machine from a dealer in Alabama. It is a 18,000lbs 1996 Hitachi EX75UR-3 with a 54hp Nissan diesel with an orange paint job. Clean moderate hours (3800hrs) and in phenomenal condition. It has become an invaluable asset to our 20 acre Hurricane Katrina ravaged wooded lot.
The other day the blade control cable finally gave way. Lucky I was able to find a Deere shop that was more than helpful locating the part. As I was investigating I decided to look into changing out the hydraulic filter per Deere recommendation. They made it sound easy. This is where I need some help.
First, assume I know absolutely nothing about changing hydraulics...which is probably the case.
Second, there are no manuals for this machine available and I am shooting in the dark.
I was able to locate two filters. one small one near the hydralic pump and another long cylinder in a what seemed to be a high pressure reservoir. I took down the #'s and topped off the reservoir with what little hydraulic fluid I lost to elimate as much air as I could and resealed the plates and encasements. I did find the small filter at NAPA but the long high pressure reservoir filter will take more work to find.
I fired her up. The machine responds the same with no jerking and same speed as before but now have a hissing in the hydraulic lines.
1. Is there an absolute do's and don'ts to hydraulic filter change.
2. What is the type hydrauic fluid to use on this size machine. The guys at the shop said to just use what viscosity in th emachine already. Which turns out to be Universal hydraulic/transmission fliud.
3. Will the air eventually purge the system? I assue the hissing is incidental air from accessing the filter reservoirs.
4. Any threads or good web site on this procedure.
5. Any feedback? thoughts? Need more info?
Thanks
Tim
