1-1.2. Advisories
This manual utilizes three types of advisories; defined as follows:
WARNING
A warning emphasizes information which, if disregarded, could
result in severe injury to personnel or equipment failure.
CAUTION: Emphasizes certain information or instructions, which if
disregarded, may result in damage to the engine or accessories.
NOTE: Provides special interest information, which may facilitate
performance of a procedure or operation of equipment.
Warnings and cautions precede the steps to which they apply; notes are placed in the
manner which provides the greatest clarity. Warnings, cautions, and notes do not impose
undue restrictions. Failure to heed advisories will likely result in the undesirable or unsafe
conditions the advisory was intended to prevent. Advisories are inserted to ensure
maximum safety, efficiency, and performance. Abuse, misuse, or neglect of equipment can
cause eventual engine malfunction or failure.

Introduction
1-1.4. Using this Manual
This manual, the primary engine ICA listed in Section 1-1.1, applicable FAA ADs and
Continental Motors service documents, the accessory manuals listed in Table 1-2, and all
changes incorporated in the ICAs as revisions constitute the Instructions for Continued
Airworthiness (ICAs) prepared by Continental Motors and accepted by the FAA. We
prepared this manual in a user-friendly format suited equally for electronic viewing and
print. Illustrations in this manual are for reference only, depicting the most prominent
configuration in the engine series. Consult the electronic illustrated parts catalog for
engine model-specific illustrated parts breakdowns. The current information available
from Continental Motors must be used to perform engine service, repair or overhaul.
Continental Motors provides Instructions for Continued Airworthiness based on the
design, testing, and certification of engines and parts for which Continental Motors is the
holder of the Type Certificate (TC) or Parts Manufacture Approval (PMA) issued by the
Federal Aviation Administration (FAA).
WARNING
Continental Motors Instructions for Continued Airworthiness
are applicable only to Continental Motors engines conforming
to the approved, type certified engine model configuration.
Continental Motors ICAs must not be used for aftermarket
parts or products modified by Supplemental Type Certificate.
Installation of aftermarket parts on a Continental Motors engine constitutes a deviation
from type-design criteria. Continental Motors has not participated in design, test, or
certification of any aftermarket parts. Continental Motors does not provide product
manufacturing specifications to aftermarket parts manufacturers and accepts no liability
for the suitability, durability, longevity, or safety of such parts installed on Continental
Motors engines. Installation of aftermarket parts on a Continental Motors engine must be
performed using Instructions for Continued Airworthiness prepared by the manufacturer
and approved by the FAA for the subject installation. For work with the engine installed in
the aircraft, the aircraft maintenance manual may also be required to gain access to,
perform maintenance, or install some items. Use only the current information from the
aircraft manufacturer.
Exploded assembly illustrations accompany instructions throughout the manual. Parts in
illustrations (Figure 1-1) are identified with either alpha or numerical callouts (indexes).
Corresponding parts listings follow the illustrations for reference. The first time
instructions refer to an illustration, the figure number is identified in parentheses, followed
by the callout. In subsequent parts references, only the callout will be specified unless the
referenced illustration changes.

6-4.7.5. Magneto RPM Drop Check
WARNING
Absence of RPM drop during magneto check may be an
indication of a faulty ignition circuit (Hot Magneto). Should the
propeller be turned by hand (as in during preflight), the engine
could inadvertently start and cause personal injury or death.
Flight is prohibited until the condition is corrected.
CAUTION: When operating on single ignition, some RPM drop and
slight engine roughness as each magneto is switched off should be
noted. Excessive (greater than 150 RPM) RPM drop may indicate a
faulty magneto or fouled spark plugs.
NOTE: If the engine runs roughly after single magneto operation,
increase engine speed to 2200 RPM in the BOTH position and lean the
mixture control until the RPM peaks for ten seconds before returning to
the full rich position to clear the spark plugs and smooth operation before
returning to single magneto operation.
Procedure
1. Start the engine according to the “Engine Start” instructions in Section 7-3.2.
RESULT: No defects noted. Allow the engine oil to warm to normal (100°F (38°C)
for turbocharged engines or 75°F (24°C) operating temperature.
CAUTION: Avoid prolonged single magneto operation to preclude
spark plug fouling.
NOTE: In the instructions below, the term “Magneto Switch” applies to
the method the aircraft manufacturer uses to control the magnetos. Some
manufacturers use a wafer switch to control the starter with four
additional positions for magneto control, labeled OFF, L, R and BOTH.
Toggle switches may be used to accomplish the same action. Adjust
instructions according to the available aircraft controls.
2. Throttle............................................................. 1700 RPM
3. Magneto Switch ............................................... R
RESULT: RPM drop does not exceed 150 RPM; record Left Magneto channel drop
result. Maximum allowable RPM drop spread between magneto channels is 50
RPM.
4. Magneto Switch ............................................... BOTH
5. Magneto Switch ............................................... L
RESULT: RPM drop does not exceed 150 RPM; record Right Magneto channel drop
result. Maximum allowable RPM spread between magneto channels is 50 RPM.
6. Magneto Switch ............................................... BOTH
7. Throttle............................................................. Reduce to IDLE
8. If no further checks are required, proceed to “Engine Shutdown” on page 32.

6-4.8.2. Oil Change
Perform an oil change within 30 minutes of engine shutdown (to obtain a useful oil
sample) according to the oil changes intervals specified in Section 6-2.
NOTE: More frequent oil changes are recommended under extreme usage
(flight training, shuttle service, or crop dusting) or adverse (desert or
arctic climates) weather conditions.
Procedure
1. Place a catch basin, approved for collecting oil, beneath the oil sump. Remove the
oil sump drain plug (Figure 6-7 through Figure 6-22), or quick drain fitting, and
drain the oil into the catch basin.
2. Collect an oil sample according to the “Oil Sample Collection” instructions in
Section 6-4.8.4. Inspect the oil sump drain plug for evidence of wear material. Metal
fragments on the drain plug may indicate excessive wear or part disintegration.
Evidence of bronze in the oil sump suggests piston pin bushing loss. Remove the
cylinders and inspect the piston pin bushings for proper installation according to
instructions in Section 10-10.
CAUTION: Dispose of used engine oil in accordance with local
environmental standards.
NOTE: Continental Motors recommends customers submit a sample of
the oil drained during each oil change, or if engine trouble is suspected,
for spectrographic oil analysis. The first three samples establish the oil
analysis trend baseline. 

The amount of wear material present in new, rebuilt, or overhauled
engines is typically greater during the engine break-in period, tapering off
during subsequent oil changes. If the amount of wear material does not
decrease during subsequent oil changes, note the wear material
characteristics (refer to Section 6-4.8.5, “Oil Trend Monitoring and
Spectrographic Oil Analysis”) and troubleshoot the engine according to
instructions in Chapter 8.
3. Oil Filter or Integral Screen Change
Engines covered in this manual are equipped with either a screw-on, disposable oil
filter or an integral screen (Figure 6-23). Maintenance pertaining to the filter media
is listed in the “Engine Inspection and Maintenance Schedule” in Section 6-2. To
change disposable filters, follow the instructions in step a; for the integral screen,
follow the instructions in step b.
a. Remove the oil filter (Figure 6-8 through Figure 6-22).Cut the oil filter in two
parts using an Oil Filter Can Cutter (P/N CT-923 (Table 2-1, “Special Tools
List”)).
1) Inspect the oil filter element for metal debris trapped within the filter to
assess the engine condition. If debris is found, wash the filter media in a clean
glass container to determine content. Use a magnet to differentiate the ferrous
materials from non-ferrous particulate.

6-50 Standard Practice Maintenance Manual
CHANGE 4 31 Jul 2017
Engine Inspection and Service
2) New, rebuilt, or overhauled engines exhibit more wear material during the
break-in period; material found in the filter media will diminish over time. If
wear material in the oil filter does not diminish, or increases, note the
characteristics of the wear material (Section 6-4.8.5, “Oil Trend Monitoring
and Spectrographic Oil Analysis” ) and troubleshoot the engine according to
instructions in Chapter 8.
Figure 6-23. Disposable Oil Filter and Integral Screen
b. If the engine is equipped with an integral oil screen (Figure 6-23), cut the safety
wire from the oil screen and remove the fastening hardware. The integral screen
is not disposable, rinse the integral screen with mineral spirits over filter paper to
clean the media. Use a magnet to differentiate the ferrous materials from non-
ferrous particulate.
4. Install the oil filter or screen. For disposable filters, follow the instructions in step a;
for the integral screen, follow the instructions in step b.
NOTE: Spin-on oil filters are available with an anti-stick coating on the
gasket. Part numbers 658753, 658754, and 658755 oil filters feature a a
dry graphite coating and are designed to be installed dry. Before applying
any lubricant to the oil filter gasket, read the manufacturer’s instructions
(Figure 6-23.1) on the oil filter. Application of any form of lubricant to
the gasket of the anti-stick spin-on oil filter will defeat the anti-stick
properties.
a. Read the oil filter label to determine the gasket type and proceed with installation
according to the filter manufacturer’s instructions. Install the new oil filter;
torque the filter to Appendix B specifications and safety wire the filter according
to instructions in Appendix C-3.
b. After thorough cleaning, install a new copper gasket on the oil screen flange and
install the oil screen in the oil pump, or oil screen adapter. Place a new copper
gasket on the plug (or oil temperature sensor provided by aircraft manufacturer)
and thread the screen (or plug) into the housing. Torque to Appendix B
specifications and safety wire according to instructions in Appendix C-3.
