ABC damages the gasket and flies out with a high pressure
Hi guys. Recently i had problem with my cl500 with power steering (PS). It works only if more than 1000rpm. So i bought defective abc pump with good PS section and i have replaced this section to my pump. I've assemble everything do the procedure with starting this pump and everything else what mercedes procedure want. After i start the engine and everything start working well. Abc section 190bar, power stering works very well. Car was working for 20 minutes then i switched off and wait for about 10-15 min. After i start engine again fluid get out with high preasure from the pump (between pump and this cylinder which is attached to the pump). So i dissasembly everything again replace orings (not original) and assemble again. And story was excactly the same - fluid on the floor). And again a replace with other orings (not original - bit diffrent than last one) and same story. So i have done the last time with used oring from difrent hose (original but used) and again same story.
Do you think its oring issue? 1st time i start engine car working very well abc and Ps. But after time i switch off and start again its blows with high preasurre. I already ordered new original gasket and hope this will help but maybe its something else? Maybe its something making to big preasurre and blows the weakest place? I already waste 7 liters fluid 2 day job and tones of nerves. Thank you

stop trying to repair the defective pump. I've had pumps that out too much pressure and blow parts of the system up
get a rebuilt one from rock auto they are about $250

Thanks for answer sir but I’m not from US. Suspension section was working ok. I haven’t open it. I just replace rear part of pump from other. And it’s working good but second start of car destroy oring.
Can it be oring fault?
It's not your oring its a bad pump putting out too much pressure
Rock auto will ship anywhere or you can find a USA contact to buy and reship to you
That’s weird. Pump was good for 2 years and now it’s bad? I wasn’t detached because this thing happened but power steering failure. Maybe it’s true but I will try with oem oring and if it fail then I change pump.

Perhaps you'd let us know where you are from. This has proven to be useful information in the past.
Hello again. I have solution. As I said I change rear part of pump from other working one. The problem was that the abc pump was from newer car and shape of this pump was slightly different. I have to cut a piece of it and everything was on it place. So problem solved
