Assembly of the Gearing
1. For Models 3800K, 3800M or 3840K, 3840M, if the Spindle Planet
Gear Bearings (36) were removed, press new Bearings into the
Planet Gears (35) using a needle bearing inserting tool. Press the
Bearings into the Gear until they are flush with the face of the Gear.
If any Gears are damaged, install a complete new set of Gears. Do
not mix old Gears with new Gears in the same motor.
For all Models except 3800K, 3800M or 3840K, 3840M, if the
Spindle Planet Gear Bushings (37) were removed, press new
Bushings into the Planet Gears (35). Press the Bushings into the
Gear until they are flush with the face of the Gear. If any Gears are
damaged, install a complete new set of Gears. Do not mix old Gears
with new Gears in the same motor.
2. Support the web at the output end of the Spindle (33) on the table
of an arbor press and position an assembled Spindle Planet Gear
in the web. The holes in the webs of the Spindle are tapered and
smaller toward the output end of the Spindle. Press a Spindle planet
Gear Shaft (38) through the rear web and Gear and into the front
web until the Shaft is flush with the face of the rear web.
3. Repeat Step 2 with the remaining Spindle Planet Gears.
4. Stand the Spindle output end upward, on the table of an arbor press
and using a piece of tubing that will clear the Spindle, press the
Spindle Front Bearing (39) onto the Spindle.
5. Invert the Spindle and without applying pressure to the Spindle
Front Bearing, press the Spindle Rear Bearing (34) onto the short
hub of the Spindle.
6. Apply lubricant to the gearing and shaft and insert the assembled
Spindle, output end leading, into the end of the Gear Case (29) with
the largest opening. Push the assembly into the Gear Case until the
Spindle Front Bearing seats in the gear case bearing recess.
7. For all Models except 3800K, 3800M or 3840K, 3840M, install
the Spindle Bearing Retainer (28) in the groove inside the Gear Case
behind the assembled Spindle.
8. For all Models except 3800K, 3800M or 3840K, 3840M, if the Gear
Head Planet Gear Bearings (25) were removed from the Gear Head
Planet Gears (24), press new Bearings into the Gears using a needle
bearing inserting tool. If any Gears are damaged, install a complete
new set of Gears. Do not mix old Gears with new Gears in the same
motor.
9. For all Models except 3800K, 3800M or 3840K, 3840M, support
the web at the spline shaft end of the Gear Head (21) on the table of
an arbor press and position a Gear Head Planet Gear with a Bearing
in the web. The holes in the webs of the Gear Head are tapered and
smaller toward the spline shaft end of the Gear Head. Press a Gear
Head Planet Gear Shaft (26) through the rear web and Bearing into
the front web until the Shaft is flush with the face of the rear web.
10. For Models 3800P or 3840P, insert the Rotor Pinion (22) into the
center of the Gear Head. This must be done before installing the
second Gear in the Gear Head. It cannot be installed after a
second Gear is secured in position.
11. For all Models except 3800K, 3800M or 3840K, 3840M, repeat
Step 9 with the remaining Gear Head Planet Gear and Bearing.
12. For all Models except 3800K, 3800M or 3840K, 3840M, stand
and support the assembled Gear Head on the table of an arbor
press with the spline shaft end downward and press the Gear Head
Bearing (23) onto the hub of the Gear Head.
13. For all Models except 3800K, 3800M or 3840K, 3840M, install the
Gear Head Spacer (27) on the spline shaft of the Gear Head.
14. For all Models except 3800K, 3800M or 3840K, 3840M, apply
lubricant to the gear head gearing and while engaging the spline of
the Gear Head with the gearing of the Spindle, slide the assembled
Gear Head into the Gear Case.
Assembly of the Motor
1. Push the Rear End Plate (9), flat face leading, onto the short hub
of the Rotor (13).
2. Push the Rear Rotor Bearing (8) onto the short hub of the Rotor
into the recess of the Rear End Plate and install the Rear Rotor
Bearing Retainer (7) in the groove on the shaft of the Rotor to
retain the Bearing and End Plate.
3. Place a Vane (12) in each vane slot in the Rotor and place the
Cylinder (16) down over the Rotor and Vanes and against the Rear
End Plate make certain the holes in the Cylinder and End Plate
can be aligned. If they can’t, invert the Cylinder.
4. Press the Front Rotor Bearing (18) into the smaller bearing recess
of the Front End Plate (17).
5. Press the Front Rotor Bearing, Front End Plate leading, onto the
spline end of the rotor shaft until the End Plate contacts the
Cylinder.
6. Use a 1/8” rod approximately 10” long to align the cylinder dowel
holes in the Front End Plate, Cylinder and Rear End Plate. Insert
the end of the rod at the Rear End Plate end into the dowel hole
in the Motor Housing. Slide the assembled motor along the rod
into the Motor Housing. Slide the assembled motor along the rod
into the Motor Housing until it stops against the bottom of the
motor bore.
7. Remove the assembly rod and install the Cylinder Dowel (14) in
its place.
8. Install the Motor Retaining Ring (19) in the Motor Housing
against the Front End Plate.
9. Insert the Motor Retainer (20), large opening trailing, over
the rotor shaft and into the Motor Housing against the Motor
Retaining Ring.
10. Install the assembled Gear Case against the Motor Housing.
It may be necessary to rotate the Spindle by hand to properly
engage the gearing with the spline on the Rotor. Make certain
the Gear Head Bearing (23) or Spindle Rear Bearing (34) enters
the recess in the Front End Plate.
11. Secure the Gear Case to the Motor Housing with the three Gear
Case Cap Screws (32) and Lock Washers (4).
12. For Models with Piped-Away Exhaust, install new Exhaust
Deflector Seals (11A and 11B) in the internal grooves at each end
of the Exhaust Deflector (11).
13. Slide the Exhaust Deflector over the rear of the Motor Housing
until it stops against the Housing.
14. Position the Backhead Gasket (6) against the rear face of the
Motor Housing.
For Series 3800 Non-reversible Motors, position the Gasket to
block off the holes in the quadrant marked with an “R” if forward
rotation is desired, or to block off the holes in the quadrant with
an “F” if reverse rotation is desired.
For Series 3840 Reversible Motors, position the Gasket so that
each gasket inlet port aligns with a group of three holes through
the housing rear wall.
15. Place the Backhead (2) against the Gasket. Install the four
Backhead Cap Screws (3) and Lock Washers (4) to secure the
Backhead and Exhaust Deflector to the Motor Housing.
16. Install one Air Strainer (1) for non-reversible models and two Air
Strainers for reversible models in the Backhead.
