FIGURE 11
Since August, 1982, the small triangular detent on the rotor of CII power steering pumps has been eliminated. See Figure 11. This mark is used to
identify the side of the rotor that must face up when re-assembling the pump. Pumps built since August have rotors with a series of bumps or a capital
letter on the opposite side of the rotor. These marks must face down when reassembling the pump or the rotor shaft "C" clip will not install and the rotor
will have to be pulled, turned and the springs and slippers re-installed. Dimensionally, these rotors are the same. However, for assembly purpose, it is
important that when a rotor has a triangular detent, the mark be up and when it has any other identification, the mark must be down.
Also, pumps built since February, 1983, have a different rotor retention "C" clip (See Figure 11). Either clip will fit the rotor shaft, but the new clip is
preferred.
