2-4-4. ANGLE SIZE
The magnitude of a vibration created by a u-joint
operating angle is proportional to the size of the u-
joint operating angle. IMT recommends true u-joint
operating angles of 3° or less.
Obtain the true u-joint operating angle, as explained
above, and if it is greater than 3°, compare it to the
following chart.
The angles shown on the chart are the MAXIMUM
u-joint operating angles recommended by IMT and
are directly related to the speed of the driveshaft.
Any u-joint operating angle greater than 3° will
lower u-joint life and may cause vibration.
Remember to check maximum safe driveshaft RPM
as recommended by the driveshaft manufacturer.
