IMPORTANT: Before disassembling the coring
crankshaft, label location and orientation of all com-
ponents that are to be removed. Correct component
location and orientation are necessary for proper
aerator operation.
NOTE: The crankshaft bearing housings for ProCore
SR48 and SR72 series aerators are very similar. The
ProCore SR72 is shown in Figure 12.

NOTE: Many of the coring crankshaft components de-
pend on proper orientation. Crank pin (item 7) head
position, crank arm location on the coring crankshaft,
crank arm angle on the crank shaft (item 12) and bearing
housing ball bearing (item 11) flange direction all need
to be correctly placed for proper aerator operation. Dur-
ing bearing housing removal, carefully note position of
components to allow proper assembly.
