Danco model RD2000 loader question

[capt jim]

I'm new to this, so please forgive me for asking what may seem to be a dumb question.
On my Cub Cadet model 125, I am looking at the breather cap for the Danco RD2000 bucket loaders hydraulic fluid, which is located on top of the right side vertical frame...near the control levers.....and I cannot figure out how to remove the cap to check the fluid level and fill as may be needed.
I have turned the cap round and round, this way and the other way, but it does not come off. I am reluctant to get forceful with it or attempt to pry it off until I understand better how it should come off. Under the cap there are large diameter but very thin nuts...access for a wrench may be a bit tight.
I sure appreciate some good direction on this before I go and break something unnecessarily.
Thanks very much.

This may help...... click on... Manual

Thanks for the manual...that is very good information to have on hand...however, it does not mention anything about the access to the hydraulic fluid reservoir...other than to remove the cap and check the fluid level.
Here is a photo of the cap...and I have tried pulling up...pushing down...rotating it each way...many turns...all to no avail.
Do you think I should get at those nuts just under the cap and give that a try?
Is the fluid under pressure at this point?

And...many thanks to you for your postings on the starter/generator system. With your guidance I was able to correct some incorrect wiring and see the generator actually charging!
How wonderful it is to achieve a bit of success.
You are to be congratulated for you efforts on our behalf.

Jim that looks like a breather cap on top. The system is not under pressure. I would do what you suggested and thats put a wrench on that nut under it.

We need more pics of your loader!

Forgive the appearance...I am doing some work on the machine...so the hood and grill have been removed.
Note: After removing the hydraulic filler cap...which turned out to be a made up thing of several brass pipe reducers, and filling the loaders hydraulic fluid reservoir to the specified level....4 inches below the plug....I operated the loader to get the fluid in and air out.....but when the bucket was returned to ground, I noticed some fluid being forced out of the plug breather cap. I am thinking of scrapping that home made breather cap and installing a simple brass pipe plug and stop the messy goo from ooosing out and flowing down the reservoir frame. I think the manual mentions a plug...but not a breather?
I guess it can't hurt anything,eh?
Enjoy the photos.

you cant just put a plug in it..... it must be able to breath, as the cylinders push out, fluid goes into them and therefore out of the reservior. at that time the reservior will go into a vacuum. when you put the cylinders back to close, the reservior will go under pressure..... thats not good.......
