3 - 4 PROPELLER SHAFT
PROPELLER SHAFT (Continued)
This measurement will give you the transmis-
sion yoke Output Angle (A).
Fig. 4 OUTPUT ANGLE (A)
(6) Rotate propeller shaft 90 degrees and place
Inclinometer on yoke bearing parallel to the shaft
(Fig. 5). Center bubble in sight glass and record mea-
surement. This measurement can also be taken at
the rear end of the shaft.
This measurement will give you the Propeller
Shaft Angle (C).
Fig. 5 PROPELLER SHAFT ANGLE (C)
(7) Rotate propeller shaft 90 degrees and place
inclinometer on companion flange yoke bearing par-
allel to the shaft (Fig. 6). Center bubble in sight glass
and record measurement.
This measurement will give you the pinion
Companion Flange Input Angle (B).
Fig. 6 INPUT ANGLE (B)
(8) Subtract smaller figure from larger (C minus
A) to obtain Transmission/Transfer Case Output
Operating Angle.
(9) Subtract smaller figure from larger (C minus
B) to obtain axle Input Operating Angle.
Refer to rules and example in (Fig. 7) for addi-
tional information.
RULES
• Good cancellation of U-joint operating angles
should be within 1 degree.
• Operating angles should be less than 3 degrees.
• Operating angles less than 10 degrees for double
cardan U-joint.
• At least 1/2 of one degree continuous operating
propeller shaft angle.
TWO-PIECE PROPELLER SHAFT
Two-piece propeller shaft angles measurement (Fig.
8) is the same as a one-piece propeller shaft.
