4	Remove O-rings (3) from hydraulic lines (A1, B1)	 Installation: Replace O-rings (3) on hydraulic lines (A1, B1). If the O-rings are not replaced, this will lead to lower pressure being applied to the O-ring and the high system pressure will then cause a leakage at the hydraulic lines (A1, B1).
5	Install in the reverse order
