MAINTENANCE MANUAL
(4) The Textron Lycoming engine is provided with a wet sump pressure oil system having a
capacity of twelve (12) quarts. The minimum safe quantity of oil in the sump is 2-3/4 quarts.
Single or multi viscosity aviation grade oils, in accordance with latest issue of Textron Lycoming
Service Instruction 1014, are required. (See 11-20-00, Figure 1, Placard #4)
NOTE: When operating temperatures overlap the indicated ranges, use the lighter grade oil.
(5) Refer to 81-20-00, Turbocharger Pre-Lubrication, for information on prelubricating the
turbochargers after the engine oil change.
B. Draining Oil Sump
The engine should be warmed to operating temperature to ensure complete draining of the used oil.
An oil quick drain valve is located on the lower left side of the oil sump. To drain the oil, install a
suitable length of inch I.D. hose on the outlet port. Remove the safety wire from the locking device,
push “IN’’ and lock to begin draining. After all oil has drained from the sump, pull “OUT’’ and lock the
outlet port closed. Safety wire the drain outlet port closed (“OUT’’ position). Remove the drain hose
and service with the correct grade and amount of oil. Check for oil leakage and correct oil level after
ground run-up.
C. Oil Filter - Full Flow
(1) Change the oil filter after the first 25 hours of engine operation for new, overhauled or re-
manufactured engines and there after every 50 hours of engine operation; this is accomplished
by removing the lockwire from the bolt head at the end of the filter, loosening the bolt, and
removing the filter assembly from the adapter.
(2) Before discarding the filter element, remove the outer perforated paper cover and, using a
sharp knife, cut through the folds of the element at both ends, close to the metal caps. Then,
carefully unfold the pleated element and 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 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.
(3) Install new oil filter as follows:
(a) Before installing the new filter, lubricate the gasket on the filter with engine oil, then install
it. Tighten slightly more than hand tight or to 1 full turn after gasket makes contact. Do not
over torque.
(b) Run the engine and check for oil leaks; then install lockwire between nut on filter and oil
filter adapter assembly.
D. Filling Oil Sump
The oil sump should normally be filled with oil to the 12 quart mark on the engine dipstick. The
quantity of oil required for the engine may be found in 6-00-00. The specified grade of oil may be
found on the oil filter access door or in the latest revision of Textron Lycoming Service Instruction
1014. To service the engine with oil, open the access door and remove the oil filler cap.
