Hello, I bought a used ESP hydraulic block (kpl. with pump and control unit) for testing. My part has e.g. the parts numbers A1705450132 (control unit) + A0034317012 (hydraulic pump) … Example picture attached Has one of you ever unscrewed the round black hydraulic pump from the aluminium hydraulic block? If yes, then I would like to know if you can then install the hydraulic pump again without any problems or if one of you has to fli egen” and the unit can no longer be assembled … Why do I ask this question: I would like to dismantle the pump “destruct-free”, check it (e.g. condition of the coals) and then mount it again on the hydraulic block. Thank you in advance for helpful contributions! (Troll please just keep your fingers still, thank you)
