Intercylinder Baffle Inspection
NOTICE:
This inspection can be done while the intercylinder baffles are installed on the engine.
A.
This inspection is done during the visual inspection to look for premature cylinder
deterioration and make sure that intercylinder baffles are correctly fitted and installed. The
intercylinder baffles are necessary to prevent rapid deterioration of the cylinders and other
engine components because they transfer heat in piston engines. To ensure this cooling, the
intercylinder baffles must be installed intact and operating correctly.
B.
Intercylinder Baffle Inspection Procedure
(1)
Examine the intercylinder baffle (Figure 3) and
surrounding components for damage, holes, cracks,
wear, deterioration, and incorrect position. Replace a
damaged, worn, cracked or deteriorated intercylinder
baffle per the “Intercylinder Baffle Removal” and
Intercylinder Baffle Installation” procedures in this
chapter.
(2)
Tighten any loose intercylinder baffle fasteners per the
latest revision of the
Service Table of Limits SSP-1776
.
(3)
Correct the intercylinder baffle position as necessary.
(4)
Record results of this inspection and any corrective
action taken on the Visual Inspection Checklist in
Chapter 05-20.
