Need help finding ABC pump replacement guide
I have had a small/slow leak coming from the ABC pump for a while now. ABC light came on the other day, went ahead an did a ABC flush fluid replacement with 10 liters of pentosin. A couple weeks later, fluid is dirty/smells burnt already.
Now I am getting ABC Warining light coming on with ABC low pressure codes coming up. Pump is putting out 150-180 BAR for a few minutes, then it seems to just shut off and pressure drops. After I reset, pump may or may not bring pressure back up. After some research it sounds it might be a sticking valve on the pump. Sounds like it is time to change pump? I appreciate any advice.
A while back I came across a step by step with pictures, tools, parts and materials to remove and replace the ABC/power steering pump. I cant seem to find it again. Does anyone know where to find it?
EDIT: Found it! Would still appreciate any advice/input before I get started.

2004 SL600 5.5L v12, ordered with SL55 package from factory (not sure if that will make a difference).
Thank you.

Just ordered my strutmaster kit. Talk to Tammy, she is really helpful and easy to get in touch with. Installed a power steering pump from a s500 yesterday . Forgot to order the reservoir 
so that will be this weeks project.
