Lift rotor from head (17, FIGURE 3-73).
Supporting rotor (48) in weight retainer, remove screw (34), valve stop (35), spring (36), and delivery valve (37)
from rotor (48).
If damaged, remove four fuel connectors (47) from head.
Using needle nose pliers, pull flexible retaining ring (30) from retainer assembly (33).
FIGURE 3-88. Removing Pumping Plungers (Typical)
Parts should be washed in a suitable solvent and then placed in a clean pan containing clean diesel fuel or
3-27.4. Inspect and Measure.
Inspect all components for excessive wear, foreign material or corrosion, nicks or chipping, scratches or scores,
thread damage, cracks, distortion, and freedom of movement. Examine springs for fretting, wear, distortion, or
breakage. Clean and carefully check all bores, grooves, and seal seats for damage or wear of any kind.
Disassemble rotor assembly (as necessary) as follows:
Do not handle precision machined surface of rotor.
Carefully remove each roller (27, FIGURE 3-73) and shoe (28) while retaining each roller in its shoe and lay
roller and shoe pairs out on a clean surface in a manner such that they can be returned to same slots in rotor in
the same direction they were removed.
Carefully remove the plungers and lay them out on a clean surface so they can be returned to same bore in
rotor in same direction that they were removed.
3-27.4.2 Drive Shaft.
Measure distance across flats of drive tang which must not be less than 0.430 inch (10.92 mm). Shaft diameter
in drive shaft seal area must be free of nicks and scratches for seals to function properly. Moderate shaft wear
from seal lips is normal.
Do not immerse head in solvent for extended periods, as sealant damage will result.
