Drawing 20- 31
Gear Train
Turn to (drawing 30): Place the Rotor Shaft (21) assembly
partially
into the Rotor Shaft Lower Bearing Housing (25). Insert
them into the Planetary Gearhead (13), ensuring that the Input Pinion (39) has properly meshed with the gears inside of (13).
Turn to (drawing 28): Align the threaded holes of (25) with the four Long Screws (49). Tighten in a star pattern with a #1 Phillips
Screwdriver.
Slide the Rotor Shaft O-ring (50) over (21) until it touches (25).
Put the Rotor Shaft Static Seal (22), spring side out, onto (25).
Turn to (drawing 27): Insert the (13) assembly back into the Gearbox (1), aligning the threaded holes in Gearhead Flange (53)
with the through holes in (1).
Using a 3/16" slotted screwdriver, thread the Short Screws (48) into (53). Tighten in a star pattern.
Turn to (drawing 25): Insert the Output Shaft Upper Seal (23), spring side out, into the Output Shaft Bearing Housing (27).
Install the Output Shaft Seal Retaining Ring (38).
Turn to (drawing 26): Reattach the Output Shaft (12) to (13) by aligning the dimple on the flat of (13) with the setscrew hole.
Install the (62) first (do not use anti-seize) using a 3/32" Hex Key and then the (63).
Turn to (drawing 24): Place both of the Gearbox Static Seals (24), spring side out, into either end of the (1). Push the (27)
assembly over (12) and into (1).
Turn to (drawing 22, 23): Push the Rotor Shaft Upper Bearing Housing (26) over (21) and into (1). Be sure to align the Drive
Pin (59), which is pressed into the (26), with the keyway in the (1).
Turn to (drawing 20): Put the Rotor (10), carbide bearing down, onto (21). Place the Lockwasher (51) and Nut (52) onto (21).
Hold (10) stationary while tightening (52) with an 11/32" socket.
Turn to (drawing 9): Insert this assembly into the Stem (3), aligning the through holes of (26) with the threaded holes in (3).
Drawing 7, 8
Stem Collar
Place the Stem Collar (2) on Rotor Shaft Upper Bearing Housing (26), making sure the screw holes are aligned.
Using a 5/32” Hex Key, screw the SHCS (42) with their Lockwashers (41) through (2) and (26) and into the Stem (3). Tighten in
a star pattern.
Drawing 2, 3, 4
Base assembly
Turn to (drawing 3): Place the Output Pinion (11), round opening down, onto the Output Shaft (12).
Thread the Idler Shafts (15) into their respective holes in the Idler Shaft Base (28).
Install the Idler Gears (16), Idler Gear Bushing (32) down, onto (15).
Tip:
Twisting the Tee Housing (4) slightly will help (15) drop into place.
Tighten the Nut (52) and the Lockwasher (51) onto (12) with an 11/32" socket.
Turn to (drawing 2): Put the Base (14) back into (4).
Using a 1/4” Hex Key, screw the SHCS (43) and Lockwashers (44) into (28).
Drawing 1
Stator and inlet collar
Using one of the Hex Keys, rotate the Rotor (10). It should spin fairly easily and its veins must not strike the walls of the Stem
Collar (2). Continue turning the Rotor. The Nozzle and Tee Housing will slowly rotate if everything has been assembled
correctly. Insert the Stator (9) into (2). Lubricate the Small and Large Collar O-rings, (56) and (57).
Apply a generous amount of an anti-seize compound (ensuring that it is compatible with the O-ring material used in the 8) to
the threads of the Inlet Collar (8). Screw on the (8) (hand-tight only), and tighten the Collar Set Screw (45) with a 1/8" Hex Key.
