Default rebuilding a rear shock

Hi guys,
I'll start by saying I have 2 shocks, so I am abusing only one

now, I have got the nitrogen out by drilling the back of the reservoir. barely a little puff..
I was actually hoping it was just a cover for the real back plate, but it's not.

this back cover can rotate in the case of the reserevoir with some help, but it looks pressed in. I can utterly destroy it and pick it piece by piece, but is there any reason to do that ?
can I just drill it it, tap it and install a shrader valve?

an alternative is race tech which sells a cover for this reservoir , how do I place (press?) it ?

now all that is left is open up the shock itself like the guides available for the 05 RR and such, right?
what do you say, is there any oil inside ?

thanks for any help!

OK, so I got 2 circlips holding the back plate and the plate with the compression valve.
in the proccess I also disconnected the oil line.

the bladder seems intact, but alot of oil spilled out of there through the oil port.

it seems the compression valve is stuck in place.

I now have 2 new questions.
first ,how does the bladder supposed to hold the nitrogen? is there an intelligent way to take the bladder off except a dremel and brute force?
second, I attached also a pic of the compression valve. is it pinned on both sides of its circumfence ? should I bother to take it out or just leave it be?

Thanks!

I don't think you're going to get many answers to your questions Avi.
What you're trying to do is usually reserved for specialists with the right knowledge to be able to accomplish the job properly and above all safely.
In my veiw, and I don't say this often or lightly, if you don't know what you're doing, stop, give up and take the thing to a company that can do the job for you. You haven't stated what you're trying to do for one, and you don't seem to know exactly now to go about it.
A recipe for disaster either in the rebuilding or the riding thereafter.
Sorry mate but there are few people who can help you here other than the experts, and they're not going to give their secrets away are they?

Thank you for replying.
However I do have some mechanical experience.
my questions are related to the fact I haven't assembled the shock, nor there is any documentation about it, and it's not a normal rebuildable shock. I don't won't to destroy it while tearing it up, although since it's one of 2 ,if I have to I will, and then figure out how I should have taken it apart.

I do know a thing or two about safety and testing as engineer, and I assure you that if I do believe I am in over my head I won't ride it.

the amusing part, I am doing my own maintenance because the few highly recommended mechanics around here had all sorts of misheps.
I know I am working by the book with a torque meter and so far I am happier with my own work than their.


a little long speech, but in short I'd appreciate if someone will answer.

and check out Peter Verdone site, he has there a lot of professional secrets
