5000-072 ASSEMBLY INSTRUCTIONS
NOTE: SUPPORT THE FRONT OF THE ROW UNIT BEFORE LOOSENING ANY MOUNTING HARDWARE.
Step 1:
(see torsion pivot locations on pages 10 – 12 that match your devastator kit). Place the 2) 5000-454 Spacers (longer,
used on non-Horizon Geringhoff corn heads) OR 2) 5000-472 Spacers (shorter, used on Horizon Geringhoff corn heads) in the
5000-453 Geringhoff Adaptor Plate. Put the spacers against the bottom side of the corn head frame. (this is to space the
adaptor plate away from the weldments & gear box mounting straps) Insert 1) 2502-815 M16 X 140MM through the front side
of the adaptor plate on the end that the pivot assembly is not attached to. Insert 1) 2502-814 M16 X 160MM through the back
side of the adaptor plate on the end that the pivot assembly is not attached to. Align these 2 bolts with threaded holes on the
gear box & thread by hand.
NOTE: EACH 5000-167 TORSION PIVOT ASSEMBLY THAT IS RECEIVED IN THE 5000-040A – 5000-
047A CAN BE DISCARDED
Step 2:
Place the 5000-174 torsion pivot assembly on the 5000-285 adaptor aligning 2 slotted holes with the tapped holes
on the adaptor bracket & 2 slotted holes that align with the threaded holes on the gear box. Thread the 2) 2502-810 M16 X 2
X 30 bolts by hand into the tapped holes on the adaptor bracket. Thread 1) 2502-814 M16 X 160 on the front side & 1) 2502-
817 M16 X 180 on the back side into the gear boxes by hand. Tighten all mounting hardware to torque spec at this time.
Below is a diagram showing what holes on the 5000-174 torsion pivot used on Geringhoff corn heads match with the holes in
the 5000-285 adaptor plate.
Step 3:
Refer to page 14 for instructions on installing the 5000-292 torsion arm.
