11. With all the above angles recorded, these values are
checked to obtain the journal cross operating angles
of each driveshaft set to determine if they are
operating to within a 3 deg. maximum of each other.
If the operating angles or journals exceed 3 deg., it
will cause early wear, and possiseizure of the journal
to the needle bearing in the journal cap.
TORQUE ARM SHIMMING
The adding or removing of shims from the rear
torque arm will change the angle of the inter-axle driveshaft.
Therefore, it is necessary to take the inter-axle driveshaft
angle and the rear axle yoke angle after each adjustment is
made, to determine the journal operating angle.
SHORT COUPLED JOINTS
Short coupled joints must be installed so that the
front and rear joints will have equal angles which should not
exceed 3 deg.
