Below is an installation manual that can be applied to all Kleenoil Bypass filters. The instructions are generic in nature, but the steps should apply to most engine applications. Should you require assistance, please feel free to contact Us.

How to Change a Kleenoil Filter Cartridge

Step 1: Locating the pressure port and drain port

This system can only be installed on engines with pressurized lubricating oil systems. Pressure ports are generally found near the main oil filter, pressure-sending unit, or along the oil gallery path on the block. There may be pipe plugs installed in unused ports. You may also find capped T's that will also serve as a pressure port. Locate as many ports as possible to give you the ability to route the pressure hose in the least obstructive path possible.

Locate as many drain or return ports as possible. Return ports are generally on the engine block and can be found near the dipstick or in the engine sump pan. Some engines require a hole to be drilled and tapped in the gear cover plates or the valve cover. Please consult your distributor if you cannot locate drain ports prior to drilling and tapping components. Most pressure and drain ports will be 1/8 or 1/4 pipe threads.

Step 2: Determine where to mount the canister

All Kleenoil filter housings come complete with all hardware and mounting brackets. Carefully select where you will mount the unit so that the changing of the cartridge can be done easily. Make sure that the unit is mounted in the upright position with enough room left for the removal of the nuts, lid, and the replacement cartridge.

If possible, the unit should be mounted slightly higher than the highest oil level in the engine so that the engine oil will not be siphoned out when the lid is removed. Proper mounting will also allow the engine oil to drain back during shutdown, allowing a clean and easy cartridge replacement.

Step 3: Mount the canister bracket

step3Place the mounting bracket in the desired location and mark the centre of the two elongated holes with a scribe or a marker. Next, drill the holes using a 25/64 drill bit, taking care not to pierce any electrical wires, hoses or components that may be behind the drilled surface. Attach the two bolts, nuts, and star washers and tighten to 70ft/lbs. or 95Nm.

If you cannot accomplish a drill through hole where access will be available for the nuts, you will have to drill and tap the holes using any appropriate bolts you may have. When tightening the tapped bolts, do not over torque. Refer to the chart below when using different bolts for the bracket mount.

Step 4: Mounting the canister

filter-diaThere are two fittings under the canister. The one closest to the edge is the return. Consider hose routing when deciding in which direction to mount the canister. Ensure that the hood will close properly before completing the mounting of the canister. Mount the canister to the already installed bracket and install the two side bolts with the lock washers and tighten each to 70ft/lbs or 95Nm.

Step 5: Install engine fittings

First, apply teflon tape or thread sealant to the pipe thread end of the fittings to be installed for the engine pressure and drain. Then, tighten the fittings to 25ft/lbs or 34Nm. The optimal location of the canister and the fittings will differ on every application. Ideally, you should have the shortest possible hose distance. You will also want to make sure that the hoses are away from high heat sources that could damage the outer jacket of the hose. Once fittings are installed, we can proceed to cut the hoses to the required length and attach the reusable ends.

Step 6: Measuring and making the hose

You want to ensure that the hoses will be of proper length. Excess hose can cause the hose to kink or may vibrate and rub against other components during operation. Hoses that are too short place stress on the fittings and will lead to premature failure. Using the bulk hose supplied, align the hose through safe routing and cut the hose approximately 1-2 inches longer than the measured amount. You should make sure the hose is clear of debris by blowing compressed air through the hose.

1) Place component 'B' on the end of the hose and turn counter-clockwise one complete turn.

2) Insert component 'A' into component 'B' and turn clockwise by hand 2 to 3 turns.

3) Tighten component 'B' counter-clockwise with a 5/8 wrench.

4) Tighten component 'A' clockwise all the way with a 9/16 wrench.

5) Repeat above steps for the other end of the hose and complete both hoses in the same manner.

Step 7: Installing the hoses

Route and tighten both the pressure and drain hoses ensuring that they are tied with tie wraps to secure the hoses and to prevent the hoses from rattling and causing premature wear. The pressure hose is attached to the fitting closest to the centre of the unit and the drain is attached to the fitting closest to the edge of the unit.

Make sure all the fittings are tight and that the hoses are securely tied away from the heat sources and from abrasion sources. Failure to route and tie hoses properly can lead to premature failure of the hoses that may result in engine damage or personal injury.

Step 8: Checking the unit operation

Start the engine and check for leaks around all fittings and the unit lid. After one minute of running, shut the engine off and check the oil level. The oil level will have dropped slightly due to the oil filling the Kleenoil unit. Top up the engine with the correct, approved type of oil.

step7Restart the engine and run at approximately 1200rpm. Once the engine has warmed up, the inlet and drain hoses should become warm also. This will ensure that there is flow through the cartridge inside the unit. The amount of time required to heat up the oil will vary, based on the amount of oil in the engine, the ambient temperature, and the temperature of the oil at the start of the test. 

The unit has now been properly installed and checked. Should any problems or questions arise, do not hesitate to contact your distributor or our head office.
