Dewald Power Gear levelers

[darbyjudy]

I have a 2004 Gulfstream with the Dewald leveling system. I am having one of the legs rebuilt and I know it will need to have some additional oil installed. The oil that came out looked blue. What type of oil will I need to add. I have never added any oil to it. What ever is in it was put there by the factory.

From a service manual that I have...just don't mix if you are not sure of what is in there now. Most likely it is the Kendall Hyden Glacial Blu from your description...

RECOMMENDED HYDRAULIC FLUIDS FOR YOUR DEWALD HYDRAULIC PUMP
The fluids listed here are acceptable to use in your pump assembly. Contact coach manufacturer or selling dealer
for information about what specific fluid was installed in your system.
It is not recommended that hydraulic fluid and automatic transmission fluids be mixed in the reservoir.
In most applications, Type A automatic transmission fluid (ATF, Dexron III, etc.,) will work satisfactorily. Mercon V is also
recommended as an alternative fluid for Dewald hydraulic systems.
If operating in cold temperatures (less than -10° F) the jacks may extend and retract slowly.
For cold weather operation, fluid specially formulated for low temperatures may be desirable. Mobil DTE 11M, Texaco Rando
HDZ-15HVI, Kendall Hyden Glacial Blu, or any Mil. Spec. H5606 hydraulic fluids are recommended for cold weather
operation.
Please consult factory before using any other fluids than those specified here.


Hope this helps, there are services that can test your fluid and determine the vendor and type for a fee...
