7.3 DRIVELINE ISSUES
Drive Line and Flange Bolts
Ensure that:
❑ All bolts are tight. Use a torque wrench to torque bolts to the drive train
manufacturer's recommended specifications.
❑ Bolts used are “Grade 8” strength. Wherever there is a requirement for
new parts, it is recommended to use only Hale authorized replacement
parts for optimum safety of the equipment and its operators.
Issues
It is critical to use computer driveline analysis software, such as Dana’s
“The Expert,” during driveline layout. Dana’s software is available free on
the World Wide Web at:

When performing calculations, strive to achieve the lowest driveline tor-
sional and inertial vibrations, making sure to avoid severe driveline angles.
Be conservative and always err on the side of SAFETY. Always measure
the drive shaft after construction to make sure it matches the computer
design.
Remember the following points while designing a driveline:
❑ Problems can occur with or without noticeable vibration.
❑ Do not measure driveline angles using a bubble protractor. Instead, use
a digital inclinometer. Remember to zero the inclinometer on the truck
frame, not the ground.
❑ Center the sliders.
Long drivelines can lead to component vibration or failure. As the driveline
approaches half critical speed, a vibration will occur that can damage drive-
line components.
Table 7-1: Maximum Recommended Driveline Lengths, on page 91, lists the
maximum driveline length using a safety factor of 42% of critical speed.
