DRIVE COUPLING REMOVAL
A metal two-piece style drive coupling was
introduced into production on certified E7 V-MAC
engines built after July 1, 1992 — beginning with
serial No. 2P and above. When the Celeron drive
coupling requires replacement, replace with the
two-piece style drive coupling.
Refer to Figure 5-79.
1. Using injection pump drive coupling holder
J 28452-A, securely hold injection pump
outer coupling from turning while loosening
coupling retaining nut. Remove outer
coupling.
Figure 5-79 — Loosening Coupling Retaining Nut
Refer to Figure 5-80.
2. Remove coupling (inner hub) retaining nut
and washer.
Figure 5-80 — Removing Retaining Nut and Washer
Refer to Figure 5-81.
3. Using a suitable two- or three-jaw puller,
remove the inner hub from the injection
pump camshaft.
Figure 5-81 — Removing Inner Hub
DRIVE COUPLING INSTALLATION
1. Install inner hub on injection pump camshaft.
Do not install a key in injection pump camshaft.
Keying of drive coupling (inner hub) to injection
pump camshaft is not required and, if used, may
result in damage.
2. Install coupling (inner hub) washer and
retaining nut. Hand tighten.
3. Insert outer coupling on inner hub so hub-
holding tool can be used to hold inner hub.
The coupling may be installed in either
direction.
A snap ring is installed in the splined bore of the
outer coupling. Its function is to keep the outer
coupling in proper position between the injection
pump inner hub and the Econovance mating
gear.
4. Using injection pump drive coupling holder
J 28452-A, securely hold outer coupling.
Torque coupling (inner hub) retaining nut to
200 lb-ft (271 N•m) using torque wrench
J 24407 or equivalent.
