Insert the bar through the centering rings while slowly
rotating the bar. The bar must turn easily.
If the bar does not turn easily, check to make sure the
main bearing caps are installed correctly. If they appear
to be okay, move one of the centering rings to another
bearing location.
Slide one end of the bar out of a centering ring. Slide the
checking ring, Part No. ST-1177-13, onto the bar. Insert
the bar into the centering ring.
Apply lubrication to the outside diameter of the checking
ring.
Use your hands to install the checking ring into the main
bearing bore. If the ring will not slide through the bore,
check the bore for burrs. If the ring will still not slide
through the bore, the bore is undersize and must be
repaired.
