(2) Filling
The oil sump should normally be filled with oil to the mark on the engine dipstick. The quantity
of oil required for the engine may be found in 6-00-00, Chart 1. The specified grade of oil may
be found in 12-20-00, Figure 5; on the inside surface of the engine oil filler access door; or in
the appropriate vendor publication. To service the engine with oil, open the quick release oil
filler access door on top of the cowl, and remove the oil filler cap with dipstick.
(3) Oil Screen (Suction)
The oil suction screen, located on the bottom aft end of the engine sump is installed
horizontally. To remove, cut the safety wire and remove the hex head plug. The screen should
be cleaned at each oil change to remove any accumulation of sludge and to examine for metal
filings or chips. If metal particles are found in the screen , the engine should be examined for
internal damage. To avoid possible damage to the screen,.after cleaning and inspection, place
the screen inside the recess in the hex head plug, and insert the screen into the housing
When certain that the screen is properly seated, tighten and safety the plug with MS-20995-
C41 safety wire.
(4) Recommendations for Changing Oil
NO
TE: Lycoming recommends changing the oil and filter each 50 hours of operation or every
four months, whichever occurs first - for engines equipped with full flow
cartridge filters. Refer to the latest revision of Lycoming Service Instruction No. 1014
and Lycoming Service Bulletins No. 446 and No. 480.
(a) A change to additive oil should be made with a degree of caution in engines that have
been operating on straight mineral oil for several hundred hours, since the cleaning action
of some additive oils will tend to loosen sludge deposits and cause plugged oil passages.
On any engine that has been operating on straight mineral oil, and is known to be in
excessive dirty condition, do not switch to an additive or compounded oil until the engine
has been overhauled.
(b) When changing from straight mineral oil to compounded oil, the following precautionary
steps should be taken:
1
Do not add additive oil to straight mineral oil. Drain the straight mineral oil from the
engine and fill with additive oil.
2 Do not operate the engine longer than five hours before the first oil change.
3 Check all oil screens for evidence of sludge or plugging and change oil every ten
hours if sludge conditions are evident. Resume normal oil drain periods after sludge
conditions improve.
B. Oil Filter
(1) The oil filter should be replaced after each 50 hours of engine operation. This is accomplished
by removing the lockwire from the bolt head at the end of the filter housing, loosening the bolt,
and removing the filter assembly from the adapter.
(2) Before discarding the throwaway filter, remove the element for inspection by using a Champion
cutter tool, CT-470, available from Champion Spark Plug Co., Toledo, Ohio 43601. It will cut
open any spin on type oil filter for inspection. Examine the material trapped in the filter for
evidence of internal engine damage, such as chips or particles from bearings. In new or newly
overhauled engines, some small particles of metallic shavings might be found; these are
generally of no consequence and should not be confused with particles produced by
impacting, abrasion or pressure. Evidence of internal engine damage found in the oil filter
justifies further examination to determine the cause.
