Tee Housing
Slide the Tee Housing Bevel Gear (45) over the end of the Stem (38; drawing 9). Align the hole in the (45) with the Dowel Pin
(55) in the (38).
Place the Tee Housing Upper Bearing (54) onto the (38). Lubrication of the internal O-ring is recommended. The chamfer on
the edge of (54) should fit into the chamfer on the body of the (45).
Push the Tee Housing (39) over it until it is flush and fully seated. If a new (45) has been installed, there will be a slight
resistance as the external ring of this part is inserted into the (39).
Place the Tee Housing Lower Bearing (53) over the (38) and push it down fully into the space between the (38) and (39).
Lubrication of the internal O-ring is recommended.
Thread the Stem Cap (37; drawing 10) onto the end of the (38). This is a Left-Hand Thread.
Push the Nozzle Housing Lower Bearing (48) onto the (39). Lubrication of the internal O-ring is recommended. To prevent the
internal O-ring from being cut by the windows in the (39), twist the (48) as it slides over the (39).
Push the Nozzle Housing (40; drawing 11) onto the nose of the (39). If a new set of Nozzle Housing Bearings (48) and (49)
has been installed, there will be a slight resistance as the external ring of the (48) and (49) is inserted into the (40).
Rotate the Tee Housing Assembly slightly to mesh the Bevel Gears (45) and (46). Failure to ensure that the Bevel
Gears have properly mated could damage them.
Place the (49) onto the nose of the (39), push it into the space between the (39) and (40). Lubrication of the internal O-ring is
recommended.
Thread the Nozzle Housing Cover Plate (41) into the nose of the (39)

Tee Housing Cap
Screw the Stem (38) onto the Flow-Thru A2 Stem (50). This is a Left-Hand Thread.
Place the Tee Housing Cap (35) into the Tee Housing (39). Rotate the (39) until the (35) is fully engaged. Again, this is a Left-
Hand Thread. Hand Tighten to secure in place.

Stem and Geartrain
Align the Stem Large Gasket (33) with the through holes in the Flow-Thru A2 Stem (50) part.
Insert the geartrain (drawing 8) into the (50).
The geartrain may need to be rotated until the flat section of the Output Shaft Extension (44) aligns with the slot in the Tee
Housing Cap (35). There will be a slight resistance as it passes through the top Seal. The shaft is fully installed when the
flange at the end comes to rest in the (35).
Screw the Button Head Screws (51),
using a 5/64” Hex Key, into the (50). Hand-tighten in a star pattern.
Using a small screwdriver or hex key, rotate the Rotor (5) clockwise 10-20 rotations to verify there are no catches or snags
inside the geartrain.
Drawing 15
Stator and Collar
Place the Stator (4) into the Cap (2).
Thread the Collar (3) onto the (2) until it stops and captures the (4).
Tighten the Collar Set Screw (60)
