b. Disassembly (fig. 26).
(1) Remove the cover screws (1) and lockwashers (2) and disassemble the top filter body (3) and gasket (6)
from the lower filter body (11).
(2) Remove the felt with oiler (7) from the top filter body and the filter disk (9), felt (8) and filter screen (10) from
the bottom filter body.
c. Cleaning. Wash all parts, including the felts, with cleaning solvent, and blow dry with a low pressure air jet. If the
compressor has been in operation for a year or more, discard the felts and replace with new ones.
d. Reassembly (fig. 26).
(1) Place the filter disk (9) and then the filter screen (10) into the countersunk ledge of the bottom filter body
(11) to protect the body cavity which contains the air inlet opening.
(2) Insert the felt (8) into the remaining cavity in the bottom filter body. It is this latter cavity that will be filled with
radiator shutter fluid after installation.
(3) Insert the felt with oiler (7) up into the top filter body (3), threading the oiler through the oil hole in the top
body so that it can be inserted into the fluid reservoir of the bottom body.
(4) Fasten the top body (3) and gasket (6) to the bottom body with the cover screws (1) and lockwashers (2).
(5) Remove the filler plug (4) and gasket (5) from the top body, and carefully poke the oiler, or wick, down under
the felt (8). Temporarily reinstall the filler plug and gasket.
e. Installation (fig. 25).
(1) Hold the shutoff cock (29) firmly, and carefully screw the air filter (30) onto the threads of the shutoff cock.
(2) Aline the tapped holes in the bottom of the filter with the drilled holes in the rear engine support and install
the two hex head bolts (2) and lockwashers (1).
(3) Connect the air line (9) to the connector (3) in the top of the filter. Start the tube nut with the fingers; then
tighten with a proper size wrench.
(4) Fill the fluid reservoir of the filter as instructed in the lubrication order
(par. 42g) and reinstall the filler plug.
(5) Open the shutoff cock (29).
