    Q:
    How to install a Crankshaft on Lincoln Town Car? Posted by Girish K.
    A:
    Crankshaft installation is the first step in engine reassembly. The engine is flipped upside down, main bearing caps are removed, and new bearing inserts are placed. The crankshaft is carefully positioned and oil clearance is checked. The caps are installed and torqued in three steps. Grease is applied to the bearing surfaces and the crankshaft is placed back into the block. Crankshaft rotation and endplay are checked. For OHC engines, jack screws are used and the rear main oil seal is installed.
