seated against the shoulder of the frame. Make sure that the oil rings do not bind or become
damaged.

If the oil rings are not properly seated in the grooves in the shaft, insert a hook-shaped tool made
from wire through the inspection connections. Reposition the oil rings as necessary to seat them in
the grooves.

Check that the shaft turns freely.
If you notice rubbing or binding, determine the cause and correct it.
