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 5500 Cover Crop 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 and 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.
