  7. Using the Barring Tool (special tool #7471B, Barring Tool), rotate the crankshaft so all of the pistons are below TDC.
  8. Before removing the piston(s) from the bore(s):
    1. Remove any carbon ridge formations or deposits at the top of the bore with a dull scraper or soft wire brush.
    2. If cylinder bore wear ridges are found, use a ridge reamer to cut the ridge from the bore. DO NOT remove more metal than necessary to remove the ridge.
