12.
For all Models except 1801N or 1841N
, 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 (22) onto the hub of the
Gear Head.
13.
For all Models except 1801N, 1801P, 1841N or 1841P
,
slide the Gear Head Spacer (26) onto the spline shaft of
the Gear Head.
14.
For all Models except 1801N or 1841N
, 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. Position the Backhead Gasket (6) against the rear face of
the Motor Housing (14).
For Series 1801 Non-reversible Motors
, position the
Gasket to block of 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 1841 Reversible Motors
, position the Gasket
so that the gasket material dividing the central opening
separates the forward quadrant marked with an “F” from
the reverse quadrant marked with an “R.”
2. Install the Exhaust Deflector Seal (3) in the annular
groove that encircles the Backhead (2).
3. Slide the Exhaust Deflector (10) large opening end
trailing, over the Motor Housing.
4. Place the Backhead against the Gasket making sure the
Exhaust Deflector slips over the Exhaust Deflector Seal
without nicking or damaging the Seal. Install the two
Backhead Cap Screws (4) and Lock Washers (5) to
secure the Backhead and Exhaust Deflector to the Motor
Housing.
5. Thread a 6” long piece of pipe with a 3/4” external pipe
thread into the Backhead and grasp the pipe in vise jaws
with the Motor Housing upward.
6. Insert the Rear End Plate Gasket (9A) into the motor bore
opening of the Motor Housing and move it to the bottom
of the opening. Make certain the dowel holes in the
Gasket align with the Cylinder Dowel holes in the bottom
of the motor bore.
7. Push the Rear End Plate (9), flat face leading, onto the
short hub of the Rotor (12).
8. Push the Rear Rotor Bearing (8) onto the short hub of the
Rotor against 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.
9. Place a Vane (11) in each vane slot in the Rotor and
place the Cylinder (15) 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.
10. Press the Front Rotor Bearing (18) into the Front End
Plate (16).
11. Press the Front Rotor Bearing, Front End Plate leading,
onto the spline end of the rotor shaft until the End Plate
contacts the Cylinder.
12. Use a 1/8” rod approximately 9” 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 through the dowel hole in the Rear End Plate Gasket
and into the dowel hole in the Motor Housing. Slide the
assembled motor along the rod into the Motor housing
until it bottoms against Gasket.
13. Remove the assembly rod and install the Cylinder Dowel
(13) in its place.
14. Install the End Plate Gasket (17) over the hub of the
Front End Plate.
15. Install the Bearing Cage (19), end nearest the largest
outer hub trailing, over the rotor shaft and into the Motor
Housing against the End Plate Gasket.
16. 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.
17. Secure the Gear Case to the motor Housing with the two
Gear Case Cap Screws (31) and Lock Washers (5).
18. Remove the assembled motor from the vise jaws and
unscrew and remove the assembly pipe from the
Backhead. Install the Air Strainer (1) (two for reversible
models) in the Backhead.
