Overview
This installation manual is designed to assist you in the installation of your new
puraDYN®Bypass Oil Filtration System.
This manual will go over all aspects of installing the puraDYN®System on most oil-
lubricated equipment. The information in this manual will also assist you in custom
installation of the new puraDYN®System on genset, marine, heavy construction, and
other applications. At any time during the installation, if you have questions, our
technical support team is only a phone call away.
How the puraDYN®Bypass Oil Filtration System Works
The puraDYN®System has no moving parts and is designed for years of trouble-free
operation. Working in conjunction with the OEM full flow filter, our systems
continuously clean oil and improve engine performance with reduced component
wear.
Engine oil enters the puraDYN®filter through a metering jet or metering jet assembly
located on the base of the system’s housing unit. The metering jet reduces the flow of
oil going through the puraDYN® filter to approximately 6-8 gallons per hour.
Oil passes through our patented Polydry® polymer which absorbs harmful liquid
contaminant (water) that is emulsified in the oil. The oil continues to flow through
cotton media treated with CGP®, a process for chemical grafting, which naturally traps
other solid contaminants down to below one micron in size.
Certain puraDYN®filter elements also include a time-released additive package
designed to replenish depleted base additives specific to engine type, thereby
maintaining the oil’s chemical balance and viscosity. The clean oil then exits the
system through a return line back to the oil pan or sump. This cycle continues as long
as the engine or equipment is operating.
When you would typically change oil, as recommended by the OEM, complete an oil
analysis and replace the puraDYN®filter element. If the oil analysis confirms
the oil is still safe to use, there is no need to change it. Note: Use of
anything other than a genuine puraDYN®Filter Element voids the
puraDYN®Product Warranty.

Puradyn’s technical support staff.
Use Oil Analysis to confirm oil is good for continued use.
Maintain a good preventive maintenance program on engine and equipment.
Routinely check oil level using engine dipstick.
Change bypass filter cartridge according to oil analysis recommendation.
Please reference to System Startup page for adding required quantity of (charging) oil and
the added oil must be compatible with oil already in the system. Example. API–CJ-4 (API
category and brand may have differences in the additive package).

19-00134_(M25-M85)Standard Installation Manual_Rev4.Docx Page 5 of 25
System Mounting Requirements
In order to change the filter after installation, the following minimum height requirements
(clearance dimension) above each unit must be maintained:
Vertical Clearance Dimension
M25: (21.0cm)
M45: 12 inches (31.0cm)
M85: 20 inches (51.0cm)
Location: Choose a secure mounting location
on the engine railing, deck platform, or other
secure structure that meets these
requirements.
Install system near oil return port (sump)
and keep the return hose as short as
possible. Do not mount directly onto the
engine.(Note: Clean oil returns assisted
by gravity; return hose must maintain a
continuous downward-slope)
Maintain enough space both horizontal
and vertical so the system (including
mounting hardware) will not interfere with
engine parts, suspension components,
steering linkage, brake lines, electrical
system or engine control hardware.
Check for moving component clearance:
i.e. tire clearance, right full turn, left full
turn while suspension is unloaded and
fully loaded.
Recommend to maintain a position high enough so the outlet for the oil returns line
is at least twelve (12) inches above the dipstick oil level on short return lines and as
high as possible for longer return lines.
Select thick gage mounting frame location, so the weight of the system doesn’t
cause metal fatigue or damage.
Keep a safe distance from hot exhaust system components.
CAUTION! Avoid high-vibration mounting locations, which can cause
the bolts to loosen during operation.

SEQUENCE ( II ) - Install Oil Supply (Pressure) Line
Typical Oil Supply Line Connection
Install pressure port fittings:
Step 1. Find the oil pressure-sending unit or oil galley on the engine. The sending unit
normally has a wire or cable running to the dash to indicate the oil pressure to the
driver. If you are unable to connect to the oil-sending unit, find another oil port (usually
near the factory full-flow oil filter) that you can connect to for Oil Supply (pressurized).
Note: It is necessary to put a gauge on that port and run the engine at high idle to
check that the oil pressure is correct. As long as the oil pressure is under 65 psi,
you can install the standard metering jet. If the pressure is above 65 psi, please
contact Puradyn technical staff for applicability (please also review metering jet
assembly drawing for maintenance procedures).
Step 2. After locating the oil port that you will be connecting to, use the 90º- shutoff
valve supplied from the kits bag, and install the fitting to the oil port (also, a 1/8” street
tee and ¼” NPT bushing have been supplied for different adaptation). Note: 90º-
shutoff valve fitting is supplied in the “OFF” position. After system installation is
complete, remember to open the valve, so the oil can travel from the engine to the
puraDYN®System.
1. Locate oil galley
plug, oil pressure
sensor or other oil
port.
3. Connect high-pressure
hose prepared earlier to
shutoff valve fitting installed in
Step 2.
2. Using the proper sealant,
install safety shutoff valve to the
oil port found in Step 1 –may
require adaptor fitting for
different engine manufacturers.
Note: Make sure the shut-off
valve is accessible &
operable.
4. Connect high-pressure hose (from Step 3) to
supply fitting on bottom of system (FPS manifold
shown). Push-Button Sampling Valve kits available
(P/N: 15-00245 or 15-70135 –see page 13)

19-00134_(M25-M85)Standard Installation Manual_Rev4.Docx Page 8 of 25
Install Fittings to Pressure Hose
The puraDYN®system operates on oil supplied (pressurized) by the engine oil
pump. The high-pressure hose is not included in the standard model, but can
be supplied by your dealer, hydraulic parts store, most auto parts stores and
Puradyn Filter Technologies Incorporated –it is sometimes custom made in
specific kits where length of hose has been pre-determined.
Specifications
Use 3/16”I.D., 3000 psi fully braided hose rated for hydraulic oil (Puradyn part# 08-
00003 or Weatherhead # H06904 or Aeroquip # FC350-4 or equivalent).
Use proper sealants for installation of all fittings.
Take the two (2) supplied high-pressure flared reusable fittings and install them in the
following manner:
a. The shoulder nut has a reverse thread and must be screwed on in a
counterclockwise direction. As soon as the nut starts to thread, insert the flared
insert portion into the shoulder nut about three (3) turns.
b. Tighten down the shoulder nut first, with a 5/8” wrench. Next tighten the flared
insert, with a 9/16” wrench. Do these steps on both fittings.
c. The next step is to remove both flared inserts, because during the threading
process, the inserts pick up a small piece of rubber, which must be completely
removed from hose. Then re-install both flared inserts again and blow out with high
pressure air to clear out all the debris.
MALE
FEMALE
a. Cut high-
pressure hose to
desired length.
b. Shoulder Nut: Install the
reverse thread piece of the
reusable hose fitting by turning
counterclockwise on to the hose.
c. Apply drops of oil on the flared end, so it
is easier to push into the hose. Secure
this hose fitting by turning clockwise into
the first fitting.

19-00134_(M25-M85)Standard Installation Manual_Rev4.Docx Page 9 of 25
Routing and Connecting Pressure Hose
The kit comes with two reusable hose fittings for the 3/16” ID pressure hose.
Measure and cut pressure hose to the proper length. Install reusable hose
fittings to the pressure hose (as shown on previous page).
Continued from Step 2 (Page 7)
Step 3. After (engine side) shut-off valve fitting has been installed properly, connect the
pressure hose onto the shut-off valve fitting and route the hose to the system.
Step 4. Connect supply (pressure) hose that was routed from the engine side (Step 3)
to the supply fitting on the bottom of the housing unit or to optional FPS manifold.
For routing the hose, please ensure that the hose is routed in a safe, out-of-the-
way location, making sure it does not come in contact with any moving or
abrasive parts or hot exhaust manifolds. Secure the pressure hose with supplied
tie wraps to avoid moving or hot parts.
NOTE: The puraDYN®System will not affect engine oil pressure.

System Return Fitting, Determine Oil Return Location & Hose
Routing
Determine best locations to connect the oil return to engine:
The oil pan
The oil drain port
An inspection port on the side of the oil pan.
Use the following criteria to select an oil return point on the engine:
The oil return point must be discharge to a non-pressurized point of the engine.
There cannot be any backpressure on the hose.
Determine Optional Banjo fitting sizes:
Once a Return location is selected, make sure that you have the correct Banjo fitting
to attach to the oil pan. If your Banjo fitting size is not listed on web-site, please call
Technical Support toll-free (in North America) at 1-866-PURADYN (866-787-2396)
or [phone] for assistance.
Connecting the Return Line:
Step 1 - Remove oil pan drain plug and drain the old oil from the oil sump, take an oil
sample so that it can be analyzed and compared with future oil analysis.
Install 5/8” Return hose onto the 90º elbow fitting or optional banjo fitting and connected
to the oil drain plug hole. Using supplied hose clamp, to secure hose onto the fitting.
Step. 2 - After replacing the drain plug with puraDYN®Banjo fitting or a 90º elbow fitting,
route the Return hose to the secured Unit. Make sure the hose does not touch any
moving or hot parts. Secure the hose with the tie wraps provided.
Step. 3 - After routing is determined, measure and cut return hose to the proper length.
Before installing, make sure the hose is clean and there is no debris lodged in the line
(use pressurized air to blow out the debris, etc.). Connect the Return hose to the barbed
male fitting. Lube the inside of the hose and push it all the way onto the fitting.
When routing the oil return hose from the puraDYN®system to the engine, make
sure of the following:
The return hose should be constantly descending, (recommend 12” above oil
pan) with no traps or sharp bends.
Be sure that the hose does not come in contact with abrasive or moving parts
or hot exhaust manifolds. Secure the hose using supplied tie wraps.

Oil Analysis Data Interpretation
The Puradyn Filter Technologies Oil Management Program uses oil analysis
results to assist our customers in achieving the benefits of extended oil drain
intervals and longer service life for their engines and equipment.
Oil analysis is the key to achieving the benefits that optimize oil life and extend
drain intervals. In addition, oil analysis is the only economical way to measure
wear or contamination in the engine or equipment. Of primary importance is the
interpretation of the test data. Typical Oil Analysis Report usually presents the
data in an easy to understand format and results.
Typical puraDYN®oil analysis conducted by an independent laboratory will
contain the following parameters and provide a recommendation to continue
usage of oil OR change oil.
Additive Metals
Total Base Number (TBN) ability to neutralize acid
Wear metals
Liquid Contaminant
Solid Contaminants
These data must be monitored to fully evaluate the lubrication system. The
analysis will provide a “picture” and / or warning, if necessary, of any existing or
potential problems.
Note: Oil analysis is required in order to maintain Puradyn’s warranty
and ensure your puraDYN®System filtered oil meets engine
manufacturer’s oil specifications.

19-00134_(M25-M85)Standard Installation Manual_Rev4.Docx Page 15 of 25
Oil Analysis and Service Schedules
Replace the puraDYN filter element and perform oil analysis at the oil change intervals
recommended by your equipment's Original Engine Manufacturer (OEM). As long as
the oil analysis confirms that the oil is suitable for continued use, the oil does not
need to be changed.

Oil analysis is a fast, non-invasive way to monitor the condition of your engine or
hydraulic oil and is key to evaluating the benefits that result from optimized oil life and
extended oil drain intervals. In addition, oil analysis is the only economical way to
measure wear or contamination in the engine or equipment and often serves as an
indicator of potentially costly problems.
Samples are easily taken from the oil sample valve provided with each unit. Sampling
the oil before it enters the puraDYN system enables an accurate assessment of the
condition of the equipment. The oil analysis is conducted by an independent laboratory
and is reported in a three-tier test that includes: spectrographic metals, wear metals,
and contaminant metals (these metals must be monitored to fully evaluate the
lubrication)
For extended oil drain practices relative to over the road trucks, Puradyn follows the
Technology & Maintenance Council’s (TMC) stringent requirements.

Questions & Answers
Q. What type of oil should be used with the puraDYN®System?
A. Any high quality oil with a high total base number (TBN) or additive
package that meets or exceeds the specifications established or
recommended by the OEM.
Q. Will the puraDYN®System work with the new extended change
interval synthetic oils?
A. Yes. The puraDYN® System is completely compatible with synthetic
oils. Although these oils have a superior lubrication value over
mineral oils, they are still susceptible to solid contamination buildup
and liquid contaminants, such as water and fuel dilution.
Q. Can puraDYN®System be used on any engine?
A. The puraDYN® System can be installed on almost any engine such as
automobiles, trucks, buses, boats, generators or any other types of
industrial equipment with an engine or pressurized lubricating system.
Q. Will the installation of the puraDYN®System on my engine or
other type of equipment affects the manufacturer’s warranty?
A. No. The puraDYN® System is a bypass filter cleaning the oil at a rate of
6 gallons (24 liters) per hour and is used in addition to the OEM full
flow filter. It enhances the OEM full-flow filter’s performance, greatly
extending its life. We have opinion letters from most major engine
manufacturers, such as Detroit Diesel, Caterpillar, Cummins, Ford
Motor Co., and many others (copies available upon request), which
state that the installation and use of a non-factory accessory, such as
the puraDYN® System, does not, in itself, void the manufacturer’s
warranty.
Q. Can puraDYN®System be used on other equipment besides
engines?
A. Yes. The puraDYN® System can be used on many types of hydraulic
equipment and compressors as well as most engines that do not use a
pressurized sump.

19-00134_(M25-M85)Standard Installation Manual_Rev4.Docx Page 18 of 25
Q. How difficult is it to install the puraDYN®System?
A. The puraDYN® System can be easily installed on almost any engine
(this includes engines with metric fittings) in usually 2 hours or less.
Detailed instructions for do-it-yourself installations are provided or any
qualified mechanic can easily perform the installation.
Q. Will the puraDYN®System cause a drop in oil pressure?
A. No. The oil will build up a head of pressure against the metering jet at
the bottom of the puraDYN® System and will not change the oil
pressure of the engine or affect the normal operation of the engine or
the OEM full flow filter.
Q. At what rate does the puraDYN®System clean the oil?
A. The puraDYN® System cleans the oil at approximately 6 gallons per
hour at 65 psi.
Q. What is the puraDYN®System warranty?
A. The puraDYN® System carries a 5-year unlimited miles or hours
warranty against defects in materials and workmanship, with a six-
month money-back performance guarantee, Consumables Not
Covered include O-rings, Gaskets and Filter Elements from normal
wear”. Please call Puradyn for more details.
Q. Should I change my existing oil when fitting a puraDYN®System to
my truck, car, or other equipment?
A. Yes. It is best to start out with new oil where the viscosity and additive
levels are a known factor. In addition, we recommend taking a sample
of the new oil and a sample of the drained oil to establish a base line
for later comparisons.

Maintenance:
Cleaning the Metering Jet Assembly
Rarely does the metering jet itself get plugged. However, the protective mesh
screen may build up debris or large particles that could impede oil flow over time.
IMPORTANT: When the engine or equipment is turned off. Carefully remove
the supply hose from each supply fitting (residual oil may still be present in
fittings, bypass system or hose). Blow out the oil supply hose with high air
pressure before proceeding to refastening supply hose. Failure to do so will
result in hose, screen or metering jet becoming clogged again.
Canister and Metering Jet Dis-Assembly
1) Loosen and remove supply fittings on the bottom of the housing unit.
2) Remove the screen from the supply port (use caution to avoid damaging
port threads).
3) Using a Hex Drive remove the metering jet.
4) Reinstall in reverse order from Step 3.
