IMPORTANT: Before disassembling the coring
crankshaft, label location and orientation of compo-
nents that are to be removed. Correct component
location and orientation are necessary for proper
aerator operation.
NOTE: The connecting rod assemblies for ProCore
SR48 and SR72 series aerators are very similar. The
ProCore SR72 is shown in Figure 9.
