Nozzle housing
Step 1
1. Place the larger nozzle housing bearing (25)
and seal (27) (spring side out) onto the nose
of the tee housing (8.1). Ensure the pin (8.3)
is aligns with the hole in the (25). Failure to
align the inner and outer pins (8.3, 10.2) may
crack and permanently damage the bearings.
2. Push the nozzle housing assembly onto the
nose of the (8.1).
3. Rotate the nozzle housing assembly slightly
to mesh the bevel gears (17.1 and 18). Failure
to ensure that the bevel gears have properly
mated could damage them.
4. Place the outer (27) (spring side in) over the
nose of the (8.1).
5. Install the thin bearing (24) into the nose plate
(10.1). Ensure the pin (10.2) aligns with the
hole in the (24).
6. Then, using the (10.1/24), push the (27) into
the annular space between the (8.1) and
nozzle housing cup (9.3).
7. Using a screwdriver, screw the nose plate
(10.1) into the (8.1).

NOTE
* Note that failure to align the pin (8.3) into the inner tee housing bearing (25) and the outer pin (10.2) pin into the outer tee
housing bearing (24) will crack the bearing and render it unusable.
NOTE
** Important to use a wide blade screw driver.
Completed assembly
Step 1
1. Rotate the rotor (32.1) using a hex key. It should spin easily
and its vanes must not strike the walls of the cap (6). Continue
turning the rotor several dozen times. The nozzle and tee
housing will slowly rotate if everything has been assembled
correctly.
2. Insert the stator (12) into the (6).
3. Screw on the collar (11) (hand-tight only), and tighten the collar
set screw (30) with a 3/32” hex key.

WARNING
Hold or turn on stem (7.1). Do NOT hold or turn on tee housing
(8.1) or tee housing cap (15). Doing so will damage the gear train.
