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
possible seizure 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.
