Balance Shaft: Installation

WARNING: This page is about a different car, the 2005 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Install new O-rings on the carrier pins and oil pick up tube before assembly.

NOTE: Before installation of the balance shaft assembly, the # 1 cylinder must be brought to TDC, or the 12 O'clock position. There is a line on the front of the crankshaft hub, next to the front crankshaft bolt, that may assist the alignment.

Remove the vibration damper and roll engine over by hand until the witness line on the front of the crankshaft hub is at the 12 O'clock, or TDC position. Once the # 1 cylinder is brought to TDC, the balance shaft assembly can be installed.
