1. Provide for length change
In straight hose installations allow enough
slack in the hose line to provide for changes
in length that will occur when pressure is
applied. This change in length can be from
+2% to -4%.

7. Secure for protection
Install hose runs to avoid rubbing or abrasion. Use clamps to support long runs of hose or to
keep hose away from moving parts. It is important that the clamps do not allow the hose to
move. This movement will cause abrasion and premature hose failure.

WRONG
8. Avoid Improper Hose Movement
Make sure relative motion of the machine com-
ponents produces bending rather than twisting
of the hose. Hose should be routed so that the flex
is in the same plane as the equipment movement.
RIGHT
WRONG
5. Use proper bend radius
Keep the bend radius of the hose as large as
possible to avoid collapsing of the hose and
restriction of flow. Follow catalog specs on min-
imum bend radii.
RIGHT
WRONG
6. Use proper bend radius (cont.)
Maximum bend radius is measured on the
inside bend of the hose. To determine minimum
bend, divide the total distance between ends
(B length) by 2. For example 8 = 6, minimum
bend radius = 3.

2. Avoid twisting and orient properly
Do not twist hose during installation. This can be
determined by the printed layline on the hose.
Pressure applied to a twisted hose can cause
hose failure or loosening of connections.

WRONG
3. Protect from hazardous environment
Keep hose away from hot parts. High ambient
temperature will shorten hose life. If you can not
route it away from the heat source, insulate it.

To order By-Pass Oil Filter Parts or oil sample kits, consult your AMSOIL Dealer or the AMSOIL Product Price List for your country.
4. Avoid mechanical strain
Use elbows and adapters in the installation to
relieve strain on the assembly, and to provide
easier and neater installations that are accessible
for inspection and maintenance.
AMSOIL Oil Filter Change Recommendations
Vehicles with Gasoline or Diesel Fueled Engines
•
EaO and Donaldson Endurance ELF 7349
(Dodge Cummins 5.9L): Up to 25,000 miles (15,000 miles for severe service) or one-year
service life, whichever comes first, when used in conjunction with AMSOIL Synthetic oil. Always change oil filter at time of oil change.
•
EaBP By-pass Filters:
Should be changed every other full flow filter change up to 60,000 miles, whichever comes first. When used
with other brands of motor oil or full flow filters, the EaBP should be changed every other full flow filter change. AMSOIL recommends
using oil analysis when extending oil drain intervals.
•
Donaldson Endurance:
Heavy-duty commercial vehicles and off road equipment, when used in conjunction with AMSOIL Synthetic oil,
up to two times longer than OEM* recommendations, not to exceed 60,000 miles for on-highway diesel applications. Always change
oil filter at the time of oil change.
•
WIX and Donaldson”P” Series:
OEM* Recommendations.
•
MANN Filters:
Guaranteed up to 7,500 miles when used in conjunction with AMSOIL Synthetic Motor Oil.
Stationary Engines
•
EaO and Donaldson Endurance:
Up to two times longer than OEM* recommendations. Always change oil filter at time of oil change.
•
WIX and Donaldson”P” Series:
OEM* Recommendations.
