NOTE: The bearing housings used on ProCore 1298
aerators are identical. Coring crankshaft positions are
identified based on their relationship with the crankshaft
driven pulley. The #1 position is at the pulley side of the
coring crankshaft (Fig. 18).
IMPORTANT: Before disassembling the coring
crankshaft, label location of components that are to
be removed. Correct component location and orien-
tation are necessary for proper aerator operation.
