General Overview — MasterLube Mounting
& Operating Instructions
MasterLube Electric
Operation — “Electric Valve”
To Prelubricate the engine before initial start up, turn the key or main
power switch to the run position. Depress the MasterLube switch to the
spring loaded on position and wait four to eight seconds, or until oil
pressure registers on the engine's oil gauge. Now release the switch to
shut off the MasterLube’s valve assembly and start the engine.
Once the engine is running, even with the
valve shut off, the cylinder is automatically refilled with the oil that
was just used to Prelubricate the engine, and is ready for the next start
cycle.
Mounting
The unit needs to be mounted within 20 degrees of vertical for maximum
efficiency, and for proper operation of the “Mechanical Level Control”.
When initially mounting the system, locate the oil “inlet” on
the engine to ensure the steel braided hose will reach. The air valve/plug
assembly needs to be accessible to add oil and to pressurize the system,
as well as to have the ability to read the MasterLube gauge.
Clamping
Mounting the upper clamps together and with the bolts on opposites side
of the cylinder provides the most stable style of mounting. The lower
valve clamp will keep the system extremely stable and prevent the cylinder
from sliding.
Hose Connection
The hose connection should be considered before mounting the unit to ensure
that the hose is of proper length. The hose connects to the engines pressurized
oiling galleys. The connection should be sealed with Teflon paste only,
and the swivel connection needs no sealant
Engine Connection
When the system is to be used as a "Prelubrication only" type
of system, a 1/8” or 1/4" pipe port into the engine is adequate.
The smaller the port the longer it will take the system to Prelubricated
the engine. If the system is also going to be used as an Accumulator System,
then a 1/4” pipe threaded port engine connection or larger should
be used for adequate oil flow to protect the engine and to prevent pressure
fluctuations.
Gauge
Can be mounted remotely, and at a 45 to 90 degree angle so it can be easily
viewed. It displays the pressure in the cylinder, and must be visible
for calibration and checking the systems operation.
Black Wire
The black wire supplies power to Electronic Valve, and is connected to
a spring loaded switch when the system is being used for Prelubrication.
If the system is also to be used as an Accumulator, then the switch needs
a “locked on" position. The optional MasterLube switch has both
a “locked on” position, with “center” being "off"
and the other position being “spring loaded on”.
Calibration
Always release any cylinder pressure through the fill plug assembly before
removing it! Be sure the Mechanical Level Control ball is free in the
cylinder or is floating. Fill the cylinder 1/2 full of oil, reinstall
the plug assembly Now pressurize the system, preferably with nitrogen,
to the same maximum pressure that your engine creates. Always check the
air valve and plug sealing O-ring with soapy water to check for pressure
leaks after calibrating the MasterLube System.
Checking Calibration
The best way to check for the proper “Gas charge to Oil” ratio,
which should always be done with the engine “cold”, we recommend
a 50% air to 50% oil ratio for most applications.
Turn on the MasterLube system switch and
allow all the oil to flow into the engine (even if the engines oil pressure
gauge shows pressure), until the MasterLube gauge quits moving. The Mechanical
Level Control is now “seated”. Check the pressure remaining
in the cylinder on the MasterLube gauge. If the gauge is reading “Zero”,
check the pressure at the air valve fitting like you would in checking
tire pressure. The remaining pressure should be approximately +/-5 PSI,
half of the engine's maximum pressure used to initially charge the system.
Adjust the pressure as necessary to achieve the proper reading. This will
insure that the system is calibrated with the proper ratio of gas pressure
to oil.
