fully, either it is excessively worn or check valve is
leaking. To check for leaking valve, repeat
compression test while plugging end of oil inlet
tube with other hand. If plunger still does not kick
back promptly it and the cylinder are excessively
worn. If it does kick back on the second test, either
check valve seat is worn and leaking or it is dirty.
Clean cylinder again and repeat first test (tube
open). If plunger still does not kick back, valve is
defective. Any unit failing to pass this rough check
must be discarded. Discard both plunger and
cylinder, since these parts are selectively-fitted and
are not interchangeable.
6-25. INTAKE TUBES.
Inspect intake tubes for
distortion, cracks and out-of-roundness. All other
types of damage will require replacement of the
part.
6-26. LUBRICATION SYSTEM.
Visually
inspect all parts of the system in accordance with
the instructions in paragraphs 6-4, 6-8, 6-9 and
6-10.
6-27. FUEL INJECTION SYSTEM.
Further
disassembly of the fuel injection system is not
recommended unless proper flow equipment is
available. For complete overhaul instructions see
Fuel Injection Overhaul Manual and Parts Catalog,
Form X-30091.
6-28. IGNITION SYSTEM.
Teledyne
Continental Motors recommends replacement of the
complete ignition harness at every engine overhaul.

AND PART
INSPECT NATURE OF INSPECTION
SPECIAL
CONSIDERATIONS
CYLINDER ASSEMBLY
HEAD & BARREL
Head/Barrel Junction Discoloration, Seepage. See Section 5-22.
Interior Walls Corrosion, pitting, scoring. Defects not permissible
after removal of glaze.
Bore Diameters Wear in ring traversed area
and step at top. Use dial-type
gauge set to zero near open
end of bore.
After honing or roughening of
glaze measure bore
diameters, out-of-roundness
and taper.
Refer to Table of limits for
standard size bore or for
over-size bore.
Dimensional honing should
re- move ring step of more
than 0.002 inch diameter.
Taper limit (Table of limits)
must not be exceeded by
honing.
Bore Walls After roughening or honing,
inspect scratch pattern and, if
possible, measure surface
roughness in micro inches
RMS of 10% of cylinders as a
quality check.
Refer to Table of Limits.
Stem Holes in
Valve Guides
Scoring, diameter, flare at
ends.
Diameters of stem holes in
new guides must be within
limits for new parts and free
of tool marks.
