To install the white lower snap ring and inlet valve into the rotor’s body, rst load the white lower snap ring and valve
to the tool. To do so, hold the valve in the palm of the hand as shown (g 117). In the other hand, take the white lower
snap ring. Notice the white lower snap ring has a step feature around the outside of the ring. The correct orientation
for installation is to have the widest side facing down and the thinnest side facing up. To help with this orientation, the
G900’s white lower snap ring has engraving on the upper surface that says, “This side up.” Next, place the snap ring
on top of the G900 valve as shown (g 117). Make sure that the snap ring’s upper side (thinnest side) is facing upwards.
Now rotate the snap ring so that the open ends of the snap ring are directly over the valve’s communication port (g
118). This prevents the metal bar on the valve tool from interfering with the seating of the snap ring in the body.
With the white lower snap ring resting on top of the valve as shown, load the inlet valve and snap ring to the valve
installation tool. To do so, hold the inlet valve and snap ring in one hand with the top facing toward you. Rotate the
inlet valve in your hand so that the communication port (located on the side of the inlet valve) is at the 12:00 position
while holding it in your hand (g 119). In the other hand, hold the G900 Valve Tool by the handle. The tool needs to
be held so that the pointer arrow (g 120) located on the inside of the ring at the top of the tool, is also oriented to
the 12:00 position.
Next, slightly rotate the valve installation tool counter-clockwise to the 11:30 position. This alignment will allow the
two metal hooks on the G900 valve tool to pass through the two correct openings around the outside of the inlet
valve. Press the metal hooks through the openings. Continue pressing the inlet valve and G900 Valve Tool together
compressing the spring on the tool. While holding the tool down with the spring compressed, turn the tool’s handle
clockwise until it stops (g 121). Next, release the spring’s compression by lifting the handle slightly on the G900 Valve
Tool. This action hooks and locks the inlet valve to the tool.
