2.4.1 Lubricate the Gearbox-Nose Stem O-ring #21 on the Gearbox Nose #14. Place the
four Gearbox Nose Screw O-rings #23 on their seats at the bottom of the Stem #24. Slide
the assembled Gearbox Nose into the Stem. Rotate one of them until the four holes line
up.
Attach the Gearbox Nose to the Stem with the four Gearbox Nose-Stem Screws #10
and Lockwashers #51.
2.4.2 Lubricate the Gearbox O-ring #9 on the Gearbox Nose. Slide the assembled
Gearbox #1 into the assembled Stem-Gearbox Nose. Rotate the Gearbox to line up the
four holes. Fasten the assembly with the four Gearbox Screws #22 and Lockwashers #51.
2.4.3 Install the Nozzle Bearing #38/#59 on the Tee Housing nose #35/#55. Then place
the
first
Nozzle Housing Seal #39/#61 next to the Bearing with its spring side facing
away from the Tee Housing body.
2.4.4 Place the assembled Nozzle Housing #44/#56 onto the Tee Housing #35/#55.
Rotate the Nozzle Housing #44/#56 slightly to mesh the Bevel Gears #31 and #42/#58.
2.4.5 Install the
second
Nozzle Housing Seal #39/#61 onto the Tee Housing with its
spring side facing the Nozzle Housing Bearing Cup #40/#60.
2.4.6 Insert the Nozzle Housing Bearing #38/#59 into the Nameplate #46 (#57 for
Directional). While keeping the Nameplate and Bearing together, push them all the way
onto the Tee Housing #35/#55. Rotate the Nameplate to align the two screw holes.
Install the two Nameplate Screws #47 and tighten with a Slotted Screwdriver.
2.4.7 Slide the above assembly onto the Gearbox-Stem assembly. While firmly pressing
down the above assembly, rotate the Nozzle Housing #44/#56 until the Tee Housing
Bevel Gear #31 engages with the key slot on the Gearbox Nose #14 (you'll feel it click or
engage). Now that everything is properly lined up, press the above assembly all the down
until it is firmly seated. You will know you've got it seated properly when the gap
between the Tee Housing and the base of the Gearbox Nose is about 0.050", and the
Nozzle Housing can not be rotated more than a few degrees.
2.4.8 Stand the machine upright. Place the Rotor #25 on the Input Shaft #6 followed by
the Rotor Shaft Lockwasher #26 and Rotor Retaining Nut #27. Insert a Screwdriver
downward through its blades to prevent the Rotor from turning, then tighten the Nut,
very
tightly
, with an 11/32" Hex Deep Socket and 2" Extension. If you do not hold the Rotor
still by this method, you run the risk of not tightening the Rotor tight enough, which,
eventually will allow the Rotor to turn freely on the Input Shaft. This means both that the
unit will not rotate properly and the Tee Housing Seals may become damaged.
2.4.9 Test for proper assembly by turning the Rotor with a pencil or Screwdriver. The
Input Shaft should turn very easily and the Rotor vanes must not strike the stem wall.
Continue turning and check to see that the Tee Housing turns also.
2.4.10 Place the
second
Tee Housing Seal #33 onto the Stem #24 with its spring side
facing the Tee Housing Bearing Cup #34. Then place the Tee Housing Bearing #32
above it.
