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:
