Engine Oil Pump - Installation

INSTALLATION

CAUTION: There are two different Balance Shaft Module (BSM) to engine block bolts used. 180 mm bolts with a lock-patch on the threads or 185 mm bolts without lock-patch. Do not reuse the 180 mm bolts. Always discard 180 mm bolts after removing. Failure to replace these bolts can result in engine damage. The 185 mm bolts are reusable. Install the same length bolts that were removed and use either four new 180 mm bolts or four 185 mm bolts.





1. The 185 mm (7.283 in.) length bolts must be checked for stretching. Check the bolts with a straight edge for necking (2). If the bolts are necked down, they must be replaced.





2. Clean BSM mounting holes with Mopar(R) brake parts cleaner.
3. If chain was removed, align marks on crankshaft sprocket (2) and chain (1).
4. Align marks on oil pump sprocket (5) and chain (4).
5. Install chain on sprocket.
6. Pivot BSM assembly upwards and position on ladder frame.





7. Start BSM mounting bolts by hand.

NOTE: Use a three step procedure when tightening BSM mounting bolts. For new 180 mm bolts, go to step 8. For 185 mm bolts, go to step 9.

8. Tighten new 180 mm BSM mounting bolts as follows:
a. Tighten to 15 Nm (11 ft. lbs.) in the sequence shown.
b. Tighten to 33 Nm (24 ft. lbs.) in the sequence shown.
c. Rotate bolts an additional 90° in the sequence shown.
9. Tighten 185 mm BSM mounting bolts as follows:
a. Tighten to 15 Nm (11 ft. lbs.) in the sequence shown.
b. Tighten to 29 Nm (22 ft. lbs.) in the sequence shown.
c. Rotate bolts an additional 90° in the sequence shown.
