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 below lists the maxi-
mum driveline length using a safety factor of 42% of critical speed.
This table is based on a 0.134” (3.4 mm) wall thickness. Although wall
thickness does not have a significant effect on drive shaft length for this cal-
culation, it does have some effect.
