Geartrain Continued
Alternate Tip:
An alternate procedure is to build up the geartrain outside of the Planetary Ring Gear (12).
Place the Planetary Output Shaft Washer (20) onto the shaft of the Output Shaft Assembly (21; drawing 3).
Hold this assembly in the right hand, with thumb, middle and ring fingers, leaving the index finger free. With
the left hand, place a Planet Gear Washer (16) on each Planet Gear Idler Shaft (17). Place a Planet Gear
Assembly (15; drawing 5) on each (17). Place a Planetary Gearhead Large Washer (13) on top of the (15)s.
Place a Planet Gear Carrier Assembly (18; drawing 4) through the (15)s and on top of the 13). Make sure that
the (15)s mesh by spinning the (drawing 4).
Repeat this procedure until every (drawing 4), (16), (drawing 5), and (13) are in place on the (21; drawing 3).
Place the ring finger of the right hand on top of this geartrain Assembly.
CAREFULLY
insert the tip of the (21;
drawing 3) into the (12). The tip of the geartrain assembly should start to protrude from the bottom of the
Planetary Output Shaft Upper Bushing (22). Carefully remove the right hand index finger from the geartrain
assembly and replace it with the index finger of the left hand.
Twist the (21; drawing 3) in an oscillating manner with the remaining fingers of the right hand and the index
finger of the left hand and pushing down with the left hand index finger. The (drawing 5)s will mesh with the
Planet Gear Carrier Pinion (19) on the Planet Gear Carrier(18) and the (12) and the assembly will drop into the
(12). Be careful to hold the geartrain assembly as this happens, so as the geartrain stays together
Continue this process until all tiers of the (drawing 5)s are in place. As stated previously, it is recommended,
that the parts be installed back into the gearhead in their original order.
Place the Planetary Gearhead Top Washer (29) onto the top layer of Planet Gears (15; drawing 5).
Position the Body Gasket (32) over the Upper Stem (1), aligning the smallest holes with the small threaded holes for the
Upper Stem Small Screws (28).
Install the Input Shaft Assembly (9; drawing 6) into the center of the assembly, such that the Input Pinion (6) engages with the
top (15)s. Test the geartrain alignment by twisting the (9) in an oscillating manner. The Output Shaft Assembly (21; drawing 3)
should spin at a very slow speed as compared to the (9).
Position the Gearhead Upper Flange Assembly (10; drawing 1) over the (9). Align the holes in the (10) with the holes in the
(1). Pass the second set of (28)s through the (10)
and, using a 5/64” Hex Key,
lightly
tighten the (28)s into the (1).
Place the Rotor (5; drawing 7) {Carbide Bearing (7) down} over the (9).
Using a 1/4” socket, tighten the Rotor Nut (30) and Rotor Gasket (34) onto the (9).
Rotate the (5) 10-20 times in a clockwise manner to verify there are no catches or snags within the geartrain. If there are any
catches or drag within the gearhead, stop immediately.
Replace the Dowel Pin (52) into the (21) and then place the Output Shaft Extension (44) over the end of the (21). Align the
slot on the (44) to the (52) through the (21) and press the two shafts together fully.

Cap
Position the Body Gasket (32) over the Gearhead Upper Flange (10), aligning the smallest holes of the (32) with the holes for
Upper Stem Small Screws (28).
Place the Cap (2) on the geartrain assembly, aligning the Dowel Pins (63) and holes.
Using a 3/32” Hex Key, screw the Cap Screws (57) into the Upper Stem (1). Tighten in a star pattern.
Drawing 11
Nozzle Housing
Install Nozzle Housing Bevel Gear Pin (62) into the hole in the Nozzle Housing (40).
Position the Nozzle Housing Bevel Gear (46) so the drilled hole lines up with the (62) and install (46) onto the (40). The lower
face of the (46) should be flush with the mating surface of the (40) with no gaps.
Install the Snap Ring (47) on the (40) using a small flat screw driver.
