OIL RECOMMENDATIONS
Refer to Maintenance.
CHECK OIL LEVEL
NOTE: To prevent extensive engine wear or damage,
never run engine with oil level below or above
operating range indicator on dipstick.
Ensure engine is cool. Clean oil fi ll/dipstick areas of any
debris.
1. Remove dipstick; wipe oil off.
2. Reinsert dipstick into tube; press completely down.
3. Remove dipstick; check oil level. Level should be at
top of indicator on dipstick.
4. If oil is low on indicator, add oil up to top of indicator
mark.
5. Reinstall and secure dipstick.
CHANGE OIL AND FILTER
Change oil while engine is warm.
1. Clean area around oil fi ll cap/dipstick, drain plug/oil
drain valve. Remove drain plug and oil fi ll cap/
dipstick. Allow oil to drain completely.
2. Clean area around oil fi lter. Place a container under
fi lter to catch any oil and remove fi lter. Wipe off
mounting surface. Reinstall drain plug. Torque to
13.6 N·m (10 ft. lb.).
3. Place new fi lter in shallow pan with open end up. Fill
with new oil until oil reaches bottom of threads. Allow
2 minutes for oil to be absorbed by fi lter material.
4. Apply a thin fi lm of clean oil to rubber gasket on new
fi lter.
5. Refer to instructions on oil fi lter for proper
installation.
6. Fill crankcase with new oil. Level should be at top of
indicator on dipstick.
OIL SENTRY
™
(if equipped)
This switch is designed to prevent engine from starting
in a low oil or no oil condition. Oil Sentry
™
may not shut
down a running engine before damage occurs. In some
applications this switch may activate a warning signal.
Read your equipment manuals for more information.
Oil Sentry
™
pressure switch is installed in closure plate
pressure port. On engines not equipped with Oil Sentry
™
installation hole is sealed with a 1/8-27 N.P.T.F. pipe
plug.
Installation
1. Apply pipe sealant with Tefl on
®
(Loctite
®
PST
®
592™
Thread Sealant or equivalent) to threads of switch.
2. Install switch into tapped hole in closure plate.
3. Torque switch to 10.1 N·m (90 in. lb.).
Testing
Compressed air, a pressure regulator, pressure gauge,
and a continuity tester are required to test switch.
1. Connect continuity tester across blade terminal and
metal case of switch. With 0 psi pressure applied to
switch, tester should indicate continuity (switch
closed).
2. Gradually increase pressure to switch. As pressure
increases through range of 7-11 psi tester should
indicate a change to no continuity (switch open).
Switch should remain open as pressure is increased
to 90 psi maximum.
3. Gradually decrease pressure through range of 7-11
psi. Tester should indicate a change to continuity
(switch closed) down to 0 psi.
4. Replace switch if it does not operate as specifi ed.
