1. Remove the rotor Jam nuts (Figure 2A, #1), and the rotors (Figure 2A, #2).
2. Remove the sleeves (Figure 2A, #5) from the rotor by turning them until the pin lines up in
the long part of the “T” shaped slot in the rotor and pulling outward.
3. The sleeve o-ring is now exposed (Figure 2A, #4) . Replacement may not be necessary every
time, but cleaning is suggested.
4. Remove the main body o-ring (Figure 2A, #7). The use of an o-ring pick is suggested.
5. Hook out the rotor o-rings (Figure 2A, #6). They will be on the shaft toward the back of the
rotor’s shoulder. Two o-ring picks may be required and replacement is suggested.
Replacement
1. Replace the main body o-rings
2. Place new rotor o-rings on the major of the spline about halfway onto the spline. Leave
them there for now.
3. Put the sleeves back onto the rotors by pushing down until the sleeve o-rings seat, then
turn either direction until the pin engages in the “T” shaped slot.
4. Place the rotors on the shaft and push carefully ensuring the rotor o-ring will seat properly.
The rotor itself will push the rotor o-rings until they seat.
5. Tighten the jam nuts.
