B. Filter selection
Any of the 3 different
sizes of the AMSOIL Spin-On By-Pass Oil Filter elements may be used with
this mount. Select the element size according to your vehicle's oil
capacity.
| Vehicle Oil Capacity |
Recommended Element |
| 15 to 18 quarts |
use two BE-90 |
| 15 to 30 quarts |
use two BE-100 |
| 15 to 42 quarts |
use two BE-110 |
Service recommendations for these filters are listed later
in these instructions. Selecting a larger filter than recommended will
extend the service interval, while selecting a smaller filter than
recommended will shorten the service interval.
C. Attaching the filter mount
1. Survey the engine compartment for possible mounting
locations. Solid structures such as the firewall, fender well, radiator
support or frame are normal locations. Refer to diagram
A for minimum area requirements and consider accessibility for
servicing.
2. Note that the filter mount can be rotated 180° in its
mounting brackets. This allows the oil supply and return hoses to enter
the mount on either the right of left hand side. Choose the side that will
minimize the need for bends in the hoses or additional hose fittings.
Refer to diagram
B for preferred mounting positions.
3. When the location has been determined, use the mounting
template provided to locate and mark mounting holes. This can be easily
done with a center punch and hammer.
4. With a 1/4" drill bit, drill out the previously marked
mounting holes and attach the two piece mount bracket. Use the 4 -1" long
1/4" bolts, nuts, small washer and fender washers provided. Note the
assembly diagram
D for details. Using two 7/16" wrenches or socket, tighten to 8
foot pounds.
5. Apply thread sealant onto the "0" ring adapter fitting
and the restrictor assembly as noted in diagram C.
Install the "0" ring adapter fitting in the mount end adjacent to
the arrows pointing IN. Install the restrictor assembly in
the mount end adjacent to the arrow pointing OUT. Using a 7/8"
wrench, tighten both fittings to 40-43 foot pounds.
Warning: The
system is designed for partial/by-pass oil flow. Failure to install the
restrictor assembly can result in serious equipment
damage.
6. Apply thread sealant as noted in diagram
C to the Allen head "0" ring plugs. Using a 5/16" Allen
head wrench, install plugs in remaining mount ports and tighten to 40-43
foot pounds. Note: If optional oil sampling valve is to be used,
refer to diagram
D and install in place of either Allen head "0" ring
plug.
7. Attach the filter mount to the mounting brackets using
4 - 1-1/2" long 1/4" bolts, nuts and washers provided. Warning: The bolts
must be installed so that the nuts are on the side opposite the filter
nipples. Failure to do this will result in the bolts hitting the oil
filters. Using two 7/16" wrenches or socket, tighten to 8 foot
pounds.
D. Oil Supply
1. Usable oil pressure sources
are available on many engine blocks. There are openings into the oil
channel through the side of the block and in the area of the existing oil
filter(s). Make sure it is an oil pressure opening by replacing the plug
with a gauge and turning the engine over, or by turning the engine over
with the plug out and watching for increased flow. DO NOT START ENGINE
WITHOUT PREPARATION TO CONTROL THE OIL FLOW. Install appropriate
fitting to accept your hose connector.
2. An alternate installation is to use the existing oil
pressure sending unit. Remove the oil pressure sending unit and install a
street tee. Then re-install the sending unit in one arm of the tee.
Note: With this installation a slightly lower oil pressure reading
may register, indicating oil flow to the by-pass filter. A change of 10%
or less is not to be considered significant.
3. Install selected hose and hose fittings between the
engine block or the remaining arm of the tee and the filter mount port
marked with the arrow pointing IN. Hose should be routed in a
manner that avoids contact with sharp or moving parts and minimizes bends.
If bends in the hose can not be avoided, make sure the bend is greater
than the minimum radius recommended by the hose manufacturer. Note:
Bends should not start at the fitting. Refer to diagram
E for suggestions on proper hose routing.
4. To maintain hose position, plastic hose ties are
advised.
E. Connect the Oil Return Line
1. Existing Porting Options: Most
engines have an oil return opening in the crankcase wall or oil pan,
usually on the same side as the oil channel pressure opening but somewhat
lower. Remove the plug and determine that it is not a pressurized port and
offers an unrestricted flow to the oil pan. Install the appropriate
fitting to accept your hose fitting. Attach and route hose, connecting to
the filter mount port marked with the arrow pointing OUT. This
should be the same port in which you previously installed the restrictor
assembly.
2. New Porting Option: Where an installation
requires a new hole (in oil pan or valve cover), a self-tapping hollow
bolt may be used. Note: The self-tapping hollow bolt should be
used on stamped metal components only.
3. Other Options: Use a hollow bolt (available
locally) to replace a cap screw holding such components as the fuel pump,
timing case, or an inspection cover. Remove the selected bolt and
determine if it provides an unrestricted passage to the oil pan. If so,
install the hollow bolt. Route and connect hose as previously described.
4. Fill the selected AMSOIL By-Pass Filter elements with
the same motor oil being used in the vehicle. Lubricate the filter gasket
with oil and spin filters onto mount. Tighten one full turn after filter
gasket first contacts mount, back off 1/8".
F. Start up procedures
1. Check that all
fittings and hoses are securely attached, and that the hoses are routed
properly.
2. Check engine oil level. Fill to full mark if
necessary.
3. Set vehicle parking brake. With transmission in
park/neutral start the engine and immediately check oil pressure.
Note: Pressure may initially take a moment or two to
rise.
Caution: Carefully check for leaks at fittings, hoses and
mount. If leaks are observed, STOP ENGINE IMMEDIATELY, repair leaks
and continue.
4. After engine has warmed, shut off and re-check engine
oil level. Fill as necessary.
5. Record vehicle mileage/operating hours and date of
installation.
G. Periodic maintenance
1. Periodic visual
inspection of the fittings and hoses is recommended. Check for leaks, hose
deterioration and cuts. Repair and/or replace as necessary.
2. Properly sized, your AMSOIL By-Pass filters will last
twice as long as your regular full-flow filters. It is recommended
however, filters be changed using an oil analysis program.
3. To change the filter elements:
