The inline oil filter should be positioned as near the oil tank
and firewall as possible, away from the engine. This will greatly reduce
vibration of the filter especially during start-up and shut-down, and
reduce the likelihood of the oil line separating from the filter. Check
the oil line and clamps during each pre-flight inspection for leaky
connections, cracked lines, or loose clamps.
Before you run your engine, and any time you disconnect the oil line for
any reason, vent the air from the oil line. Refer to the Rotax 582LC
Operators Manual, pages 15 and 16, for complete instructions, and Fig. 2
on page 16, which shows the location of the vent plug.
an added precaution, if the oil pump may have lost its prime for any
reason, you should premix 2-cycle oil with the next tank full of fuel to
ensure the engine is oiled in case the oil injection pump does not
supply oil. Monitor the oil level in the oil tank to confirm that oil is
The oil injection pump metering lever is actuated by a cable which is
synchronized with the throttle. Make sure the lever alignment mark and oil
pump marks are aligned.
Your pre-flight inspection should include a thorough inspection of the oil
injection system. Check the ends of the oil injection control cable and of
the throttle cables to see that the cables are not buckled and the sheath
ends are secure in their sockets. Check the oil level in the tank and
check the line and in-line filter. It is strongly recommend that
you check the oil level in the tank and top the oil up
prior to each flight.
Rotax 582LC is a very reliable engine and the oil injection pump may be
the most reliable part of it. To date I have never had a
problem with the pump, nor have had any customers report problems.
