Install the fuel system components in accordance with Chapter 6 and the Operator and Organizational
Remove the engine from the rebuild stand, and install it in the generator set in accordance with paragraph
Serious engine damage will result If the engine Is started before the lubrication system Is
properly filled and primed. Elapsed time between priming the lubrication system and starting
the engine shall not exceed 3 hours. If, for whatever reason, the engine cannot be started
within 3 hours after priming the lubrication system, repeat the entire priming procedure just
prior to starting the engine.
Before starting the engine, fill and prime the lubrication system in accordance with the Operator and
Organizational Maintenance Manual.
9-32. VIBRATION DAMPER REPLACEMENT.
Two persons will be required to perform the following procedure.
Remove the capscrews (1, Figure 9-59), lockplate (2), and crankshaft pulley (3).
The vibration damper Is filled with a viscous fluid. To avoid damage that could render the
damper Ineffective, do not hammer or pry on the damper during removal.
Work the vibration damper (4) off of the roll-pin (5) in front of the crankshaft. Remove the rolipin if
Clean and Inspect.
Inspect the vibration damper for indications of fluid leakage. Replace the damper if leaks are detected.
Dry cleaning solvent PD-680, Type ill, or equivalent, is flammable and moderately toxic to the
skin, eyes, and respiratory tract. Assure adequate ventilation. Skin, eye, and respiratory
protection Is required to avoid Injury to personnel.
Clean the crankshaft face, vibration damper, and crankshaft pulley thoroughly using cleaning solvent, PD-
680, Type ill, or equivalent, and dry with dean shop towels.
Avoiding the area with the stamped lettering, remove the paint from the front and rear surfaces of the
vibration damper in four areas 90 degrees apart, and 0.125 inch (3.18 mm) in from the outside edge.
Using an outside micrometer, measure and record the thickness of the vibration damper in the four
cleaned spots. Replace the damper if the thickness exceeds 2.574 inches (65.38 mm), or the thickness
varies more than 0.010 inch (2.54 mm).
Check the mating surfaces of the crankshaft, vibration damper, and crankshaft pulley for paint, nicks, or
burrs that could cause runout and vibration. Remove nicks and burrs from the mating surfaces using a flat
mill file; keep the file flat on the mating surface and remove the nick or burr only.
To avoid possible misalignment and vibration, do not paint the crankshaft and pulley mating
surfaces of the vibration damper.
Treat and paint an acceptable vibration damper and crankshaft pulley in accordance with, MIL-T-7044,
using light gray paint 16492, FED-STD-595.
