Column Removal
Flanged Column
A. Install eyebolts of sufficient size in the
column flange holes and lift the unit and
reposition the clamp below the next
column flange.
B. Use column and shaft clamps (or other
acceptable method) to safely support
and lift this assembly.
C. Unbolt column flange and lift column
enough to loosen the shaft coupling.
When all components are loose,

unit. With soft skid boards under the
column to protect the flange, slowly
lower the column and shaft assembly
onto the floor and move to a convenient
work area.

D. Repeat above steps A, B & C until all
column and shaft sections have been
removed from the unit.
E. Remove the bearing retainer assembly
for inspection and cleaning.
F. Remove shaft section from column pipe.
Remove couplings from shafts and
inspect for wear or damage.
G. Inspect bearings and retainers for
damage.
H. If the top and intermediate drive shaft
sleeves (13 & 29) show wear or damage
remove the sleeve by heating it to 350
°
F-
400
°
