Walker Ford / Lehman AirSep Kit
NOTE: Since this installation may require some kit parts to be modified it is advisable to contact
your mechanic for installation.
**INSTALLATION INSTRUCTIONS - WALKER FORD / LEHMAN**
This AIRSEP kit is designed to fit most Ford/ Lehman Diesel engines. You may require some additional fittings to
complete the installation, so it is advisable that you "LAY-OUT" the parts prior to installation to become more familiar
with the parts you have, and the fittings you may need. Some installations inside an engine compartment may require
some thought as to positioning the unit. Most installations may require a fitting to connect the AIRSEP oil drain to the
dipstick or to an auxiliary oil port above the oil pan. It may be necessary to use some of the Factory parts to complete this
installation.
1) Remove the Factory Air Filtration system and clean the mounting surface. Use caution not to damage the gasket.
2) Using the Assembly Schematic, "DRYFIT" the Walker AirSep plenum to the inlet to check for any obstructions, the
plenum is designed to fit facing either fore or aft, positioning the AirSep so that the 3/8" N.P.T. oil drain fitting is in the 6
O'clock position.
3) Once the positioning has been verified, re-install the plenum gasket and tighten the bolts, install the 2.5" I.D. hose to the
plenum and the AirSep to the 2.5" hose, tighten the hose clamps. Drain position is critical.
4) After installing and securing the AirSep, locate the engine crankcase breather. This will be on top or on the side of the
engine block.
5) Locate the 3/4" to 1/2" hose reducer and attach to a 6" x 1/2" I.D. hose supplied, next install the Vacuum Regulator into
the 3/4" I.D. straight hose. Check to guarantee that the flow direction is correct; the arrow should point toward the
AirSep. Attach to the 1/2" O.D. breather outlet
6) Connect the 3/4" Walker Flex hose from the AirSep to the Vacuum Regulator. Trim the hose as necessary to insure that
there are no "low-spots" in the flow to the AirSep blow-by inlet.
7) Using the 1/2" oil drain hose, connect to the fitting on the bottom of the Air Sep, routing to the oil return position on the
crankcase. Trim this hose as necessary to insure that there are no "low-spots" in the flow to the check valve. The check
valve must be installed no closer than 18" from the AirSep. Install check valve to supplied oil fill cap and replace existing
cap. Use caution not to leave the hose open to "chafing". The Walker check valve must be installed vertical or within 30° of
vertical to operate properly, check to guarantee the flow direction is correct, the arrow should point down from the
AirSep.
This system closes the crankcase, all other openings to the crankcase, such as breathers, down draft tubes and vents
need to be closed and / or removed.
The air filter should be cleaned every 250 hours or once a year. If the air restriction gauge on the AirSep turns red the air
filter must be cleaned or replaced. The filter supplied with the AirSep can under normal circumstances be cleaned and re-
oiled up to three times. Cleaning and re-oiling kits, part # DDF9016, are sold by Walker Engineering and our Dealers.
