G. "E" Checks and Operations (1200 Hours or 1 Year)
(1) Engine
(a) Steam clean engine
There are several reasons why the engine exterior should be kept clean.
Dirt on the outside will enter fuel and oil filter cases and rocker housings
when covers are removed unless dirt is removed first. A clean engine
will run cooler and develop less "hot-spots".
Steam cleaning is one of the most satisfactory methods of cleaning an
engine, however there are some CAUTIONS to be observed.
CAUTION: 1.

WARN IN G: 1. DO NOT USE A FLAMMABLE SOLVENT.

PROTECT (OR REMOVE) ALL ELECTRICAL ACCESSORIES,
SUCH AS VOLTAGE REGULATOR, ALTERNATOR, AND
ELECTRICAL WIRING. SEAL ALL OPENINGS.

(b) Clean fue I pump screen and magnet
See 2-2, Para. 4, C, (1) for screen and magnet removal and cleaning.
(c) Check vibration damper
The damper hub and inertia member are stamped with index marks to permit
detection of movement between the two parts (see Fig. 2). There should be
no indication of movement between the hub and the inertia member. If
index marks are not aligned, replace vibration damper.
