BOLT TORQUE
Important: Over-tightening hardware can cause just as much damage as under-tightening.
Tightening hardware beyond the recommended range can reduce its shock load capacity.
All hardware on the 5000 Devastator is either Grade 5 or Grade 8, unless otherwise noted. Grade 5 cap screws are marked
with three radial lines on the head. Grade 8 cap screws are marked with six radial lines on the head. If hardware must be
replaced, be sure to replace it with hardware of equal size, strength & thread type. Refer to the torque values chart when
tightening hardware.
The chart below is a guide for proper torque. Use it unless a specified torque is called out elsewhere in the manual.
Torque is the force applied to the end of the handle or cheater bar, times the length of the handle or bar.
Use a torque wrench wherever possible
The following table shows torque in ft.-lbs. for coarse thread hardware.
INSTALLATION TOOLS REQUIRED:
- Pneumatic or electric impact driver
- ¾ & 15/16 size sockets
- 10” impact driver extension
- Ratchet
- ¾, 15/16, & 1 1/8 size wrenches
- 5/16 Allen Wrench
- Torque Wrench

Step 4: Attach the pivot arms, using the lower of the 2 holes, to the mount brackets using
the 5/8” X 3 bolts, pivot bushings, and lock hex nuts. Tighten this hardware.
Step 5: Install the push rods into the mount brackets then attach to the pivot arms with
the 5/8” shoulder bolts, washers, and ½” jam lock nuts.
Note: The washers are installed on each side of the “eye” of the push rod.
Now install the compression spring, spring bushing, and ¾” lock hex nuts. Tighten the
hardware from Step 5 to the specification in the diagram below.
NOTE: Tightening the nut on the spring bushing more will result in added
down pressure. However, DO NOT tighten the nut on the spring bushing
down so far that spring compression limits pivot arm travel.

10
5000-022C ASSEMBLY INSTRUCTIONS
Step 6: Secure the mounting bracket installed in Step 1 at this time by tightening the 5/8 X 7” bolts & 5/8
lock nuts. Make sure the compression spring clears the cylinder channel, gathering chains, & deck plate
adjustment. The offset pivot arm clamp should be under the snout, not directly under the row.

Step 7: Install the Roller Arm Mount Tube inside the clamp channel of the pivot arms using the 5000-
138 bolt bag. Do not tighten this hardware until after the rollers have been installed in Step 8.
Step 8: Insert the shim washer over the shaft on each end of the roller. Install the bearing over the shaft on each end of the
roller so that the side of the casting that has the bearing protruding past the housing surface is towards the roller barrel & shim
washer. Lift each roller into place, install the ½” X 2 ½” bolts & tighten the ½” lock nuts. Once the roller & bearing hardware is
fastened, spin the roller to ensure the bearing was installed correctly. If the roller was installed incorrectly, the roller will not spin
or will have drag. Slide the roller mount tube to gain clearance on each end of the corn head & then tighten the hardware.
NOTE: BEARING HOUSING SHOULD BE LUBRICATED WITH POLYUREA GREASE BEFORE USE AND THEN EVERY 100 HOURS OF OPERATION

OPERATION
CORN HEAD ANGLE SHOULD BE BETWEEN 23 – 25°
FOR OPTIMUM DEVASTATATOR PERFORMANCE.
USE THE 5000-455 TO CHECK CORN HEAD ANGLE:
- Put the combine on a level surface. Lower the
Corn head to your normal working head height.
- Place the magnetic protractor on the stripper
plate to get the angle. Adjust the feeder house
as needed, fore or aft, to achieve 23 – 25 degrees.
BEARING REPLACEMENT
Put the bearing housing in a vice, use a pry bar to turn the bearing in the housing parallel with the slots, remove the old
bearing, apply anti-seize lubricant to the interior of the bearing housing, insert the new bearing in the slots, & use a pry bar to
move back to position. Wobble the bearing around to help work the lubricant into the outer race of the bearing.
STORAGE
When storing the corn head for the offseason, it is OK for the 5000 Stalk Devastators to hold some weight of the corn head whether
stored on the ground or on a trailer. Removing compression springs may help extend the service life.
