BOLT TORQUE
Mounting bolts and hardware
Before operating the Yetter Hydraulic Compressor for the first time, check to be sure that all hardware is
tight. Check all hardware again after approximately 50 hours of operation and at the beginning of each
planting season.
All hardware used on the Yetter Hydraulic Compressor is Grade 5 unless otherwise noted. Grade 5 cap
screws are marked with three 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.
Important: Over tightening hardware can cause as much damage as when under
tightening. Tightening hardware beyond the recommended range can reduce its shock load
capacity.
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 you apply to the wrench handle or the cheater
bar, times the length of the handle or bar. Use a torque wrench whenever possible.
The following table shows torque in ft. lbs. for coarse thread hardware.
Lubricate all bearings and moving parts as assembled and make certain that they work freely.
WARNING: Never work around the toolbar/implement while in a raised position without using
safety lockups.
CAUTION: The Residue manager attachments are very heavy. Pay extra attention to lifting
techniques while handling and or maneuvering the opener during assembly. Failure to do so
may lead to personal injury.
