AMSIL BMK-11 By-Pass Filter Installation Instructions

Be sure to click on links to detailed diagrams marked in text.

IMPORTANT NOTICE
Read all instructions completely before attempting to install this unit. Improper installation could result in serious system and/or equipment damage. The installation of this system is not difficult, however, some mechanical ability is necessary. If you are not comfortable with the instructions or have questions, do not attempt to install this system. Consult a mechanic or contact AMSOIL INC. for further instructions or assistance.

If installing on a Japanese- or European-built vehicle utilizing Metric or B.S.P. threads, additional parts may be required. Consult step 0.1 before you continue.

WARNING: This filter system is not designed to replace the engine's normal full-flow filter. Do not attempt to install a by-pass filter element in place of the existing full-flow filter.

WARNING: Extreme care should be taken to avoid bodily harm during installation. Before starting, ensure the engine is cool to avoid burns and never work in the engine compartment area with the engine running.

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 B for minimum area requirements and consider accessibility for servicing.

2. Refer to Diagram A 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. Install adapter fittings (BP-208) on filter mount using provided thread sealant as noted in Diagram C. If desired, 90° angle fitting (BP-52) may also be used. Using a 7/16" wrench, tighten fittings 2-3 turns beyond finger tight. Keep in mind the direction you wish to have the hoses intersect the mount.

5. With a 5/16" drill bit, drill out the previously marked mounting holes and attach the mount using the 5/16" bolts, nuts, small washer and fender washers provided. Bolts should be tightened to 16-18 foot pounds. 1/2" wrenches or socket will be required for this operation.

6. Fill the By-Pass Filter element with the same motor oil being used in the vehicle. Lubricate the filter gasket with oil and spin filter onto mount. Tighten one full turn after filter gasket first contacts mount, back off VB".

D. Oil Supply

1. Locate oil pressure sending unit (see Diagram E). Remove unit and install "T" (BP-33) using thread sealant as noted in Diagram C and tightening 2-3 turns beyond finger tight. Note: See Diagram G if oil pressure sending unit has a V4" N.P.T. thread. Note: Special adapters may be needed to install "T" on some engines. Refer to the Oil Pressure Sending Unit Information Guide. Occasionally, additional fittings may be needed.

2. Reinstall sending unit in one opening of the "T" and a fitting adapter (BP-208) in the other. Use thread sealant and tighten as noted above in D.1. Use 90° Street Elbow (BP-52) if necessary, keeping in mind the direction you wish the hose to intersect the fitting.

3. Measure the amount of hose (BP-206) you will need to run from the Oil Pressure Sending Unit "T" to the filter mount fitting labeled IN. Additional length will be required to accommodate engine movement during operation. Using a utility knife, squarely cut the hose to the proper length. Note: The hose and fittings supplied with this kit have been matched to provide maximum performance and life expectancy. Interchanging with other types or brands is not recommended and should be avoided. Should additional hose be required, it may be obtained from your AMSOIL Dealer by ordering part number BP-206.

4. Install hose fittings (BP-207) on both ends of the hose following the instructions noted in Diagram F. Tools required are one 9/16" wrench and one 11/16" wrench or vise. Note: Do not use any form of thread sealant anywhere on the BP-207 hose fittings.

5. Route and connect the hose assembly making sure the hose does not contact any hot or moving surfaces or sharp edges. Ensure a minimum of a 3/4" bend radius is maintained at all corners. Also, bends in hose should not begin at hose fittings. Using a 9/16" and 7/16" wrench, tighten hose fitting swivel nut to 130-150 inch pounds or from finger tight, rotate an additional 120° or 1/3 of a turn. See Diagrams D and H for additional details.

E. Oil Return

1. Two options are available for returning the filtered oil to the engine. The first uses a self-tapping hollow bolt (BP-40) and allows the oil to be returned to either the oil pan or a rocker arm/valve cover. The second, which uses an optional swivel fitting (BP-89), returns the oil to the oil filler cap already installed on your vehicle.

2. For option one, select either the oil pan or valve cover for installation. Note: The self- tapping hollow bolt should be used on stamped metal components only. For oil pan installation, mark a spot approximately 3" above the bottom of the pan. Avoid any pan formations that may suggest an internal obstruction. For the valve cover, choose a mounting location that will not interfere with the movement of internal components and away from the PVC pick-up.

3. Using a punch and hammer, punch a hole in the chosen location between 114" (.25") and 5/16" (.3125") in diameter. Note: Do not drill this hole as metal fillings are likely to enter the engine and it will produce a weaker attachment of the self-tapping hollow bolt.

4. Using a 9/16" wrench, thread in the self-tapping hollow bolt (BP-40) and sealing gasket (BP-41). As the bolt is tightened, make sure sealing gasket is snug all the way around bolt. Tighten bolt to 6-8 foot pounds.

5. Using a 7/16" and 9/16" wrench, install fitting adapter (BP-208) in self-tapping hollow bolt. Use a 90° Elbow (BP-52) if necessary keeping in mind the direction you wish the hose to intersect the fitting. Use thread sealant provided as noted in Diagram C. Tighten 2-3 turns beyond finger tight. Proceed to item 10.

6. For option two, remove the existing oil filler cap. Be sure there is not a PVC pick- up in this area.

7. In the center of the cap, drill a 3/8" hole.

8. Install the long threaded portion of the optional return line swivel fitting (BP-89) into the top of the oil filler cap. Secure with the provided self-locking nut and 9/16" wrench.

9. Using thread sealant, install a fitting adapter (BP-208) into the return line swivel fit- ting. Tighten 2-3 turns beyond finger tight. Reinstall oil filler cap on vehicle. A 90° Elbow (BP-52) may also be used.

10. Measure the amount of hose (BP-206) you will need to run from the self-tapping bolt or optional return line swivel fitting to the filter mount fitting labeled OUT. Additional length will be required to accommodate engine movement during operation. Using a utility knife, squarely cut the hose to the proper length.

11. Install hose fittings (BP-207) on both ends of the hose. Follow the instructions noted on diagram F. Note: Do not use any form of thread sealant anywhere on the BP-207 hose fittings.

12. Route and connect the hose assembly making sure the hose does not contact any hot or moving surfaces or sharp edges. Ensure a minimum of a 3/4" bend radius is maintained at all corners and hose bend does not begin at fitting. Tighten hose fitting swivel nut to 130-150 inch pounds or from finger tight, rotate an additional 120° or 1/3 of a turn. See Diagrams D and H for additional details.

13. Use plastic ties (BP-46) to secure hoses in position and away from damage. Trim ties, using side cutter. Note: Over tightening the plastice ties may cause the hose to collapse and restrict oil flow.

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 dete- rioration and cuts. Repair and/or replace as necessary.

2. Refer to Recommended Filter Change Interval Chart for servicing intervals.

3. To change the filter element:

a. Ensure engine is off and use caution as the engine, oil and filter may be hot and could result in an injury.
b. Using a filter wrench, remove the filter element. Dispose of properly.
c. Clean the filter gasket contact area on the mount with a clean, lint-free rag.
d. Lubricate the new filter gasket with clean oil or grease.
e. Fill filter as full as possible with engine oil.
f. Screw on new filter, tighten one full turn after filter gasket contacts mount. Back off 1/8.
g. Start engine and check for leaks.
h. Check engine oil level, fill as needed.

i. Record vehicle mileage/operating hours for future reference.

Installing an oil sampling petcock on a spin-on by-pass:
Getting a clean and uncontaminated oil sample is easy and simple when an oil sampling pet-cock is installed into the Spin-On By-Pass Oil Filter system. This can be easily done by ordering a BP-67 Kit and installing it into the by-pass system as shown here.

Oil Analysis:
1. If installing By-Pass Oil Filter with AMSOIL Air Filter and 100% Synthetic Engine Oil, in a pleasure vehicle we recommend the TRIGARD Oil Analysis Program:

a. TRIGARD 1 (Stock No. ATG-01) is the starter program. It contains registration material and 2 prepaid analyses to check oil's condition.

b. TRIGARD 2 (ATG-02) is for all subsequent oil smaples. Each ATG-02 also contains materials for 2 prepaid oil analyses.

2. For other oil analysis or commercial vehicles, order G-1318 Oil Analysis Sampling Kits (in U.S., Canada, Puerto Rico), or send samples to the lab of your choice. Consult AMSOIL Technical Services for details (or visit the Oil Analyzers Inc. website).

By-Pass oil filter return-line fitting:
A swivel fitting can be installed directly on your oil filler cap for the oil return-line from the AMSOIL By-Pass Filter. This fitting can be used (in most cases) instead of the self-tapping hollow bolt, whichj is usually installed on the oil pan.

The Return-Line Fitting is made of a sturdy brass-alloy and is constructed so that the top of the fitting can swivel. This makes it easy to take off your oil cap. The installation of the fitting is simple and generally takes 5-10 minutes. Order BP-89. Be sure there is not a PCV pick-up in this area.
