10. Test run the engine to check for leaks. Stop the
engine, allow a minute for the oil to drain down,
and recheck the level on the dipstick. Add more
oil, as necessary, so the oil level is up to but not
over the "F" mark.
NOTE: To prevent extensive engine wear or
damage, always maintain the proper oil
level in the crankcase. Never operate
the engine with the oil level below the
''L'' mark or over the ''F'' mark on the
dipstick.

Full-Pressure Lubrication System

Operation
This engine uses a full-pressure lubrication system
to deliver oil for internal lubrication. A cam driven,
oil pump located in the
™
even at low speeds and high operating temperatures.
Oil is supplied from the pump via two circuits to the
integral pressure relief valve within the oil pump
limits the maximum pressure of the system.
For a cold engine at start up, the oil pressure can
go down to 5 psi.
Service
The oil pump rotors typically require no servicing, if
normal maintenance is performed as outlined in
Section 1.
The closure plate must be removed for access to the
oil pump and the rotors. Refer to the Disassembly

light or stop the engine, depending on the application.
Operation
The pressure switch is designed to break contact
as the oil pressure increases and make contact as
the oil pressure decreases. At oil pressure above
approximately 2 to 5 psi, the switch contacts open.
At oil pressures below approximately 2 to 5 psi, the
switch contacts close.
