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 housing assemblies for
ProCore SR54 and SR70 aerators are very similar. The
ProCore SR54 is shown in Figure 11.

NOTE: Many of the coring crankshaft components de-
pend on proper orientation. Crank pin (item 2) head
position, crank arm (item 13) location on the coring
crankshaft, crank arm (item 13) angle on the crank shaft
(item 11), crank shaft (item 11) groove orientation and
ball bearing (item 8) flange direction all need to be cor-
rectly placed for proper aerator operation. During bear-
ing housing removal, carefully note position of
components to allow proper assembly.
