(3) Place Inclinometer 7663 (J-23498A) on yoke bearing (A) parallel to the shaft (Fig. 8). Center bub- This measurement will give you the transmis- sion or Output Yoke Angle (A). (4) Rotate propeller shaft 90 degrees and place Inclinometer on yoke bearing parallel to the shaft This measurement will give you the Propeller Shaft Angle (C). (5) Subtract smaller figure from larger (C minus A) to obtain Transmission Output Operating Angle. (6) Rotate propeller shaft 90 degrees and place Inclinometer on pinion yoke bearing parallel to the This measurement will give you the pinion shaft or Input Yoke Angle (B). (7) Subtract smaller figure from larger (C minus B) to obtain axle Input Operating Angle. Refer to rules given below and the example in (Fig. 11)for additional information. • Good cancellation of U–joint operating angles (within 1°). • Operating angles less than 3°. • At least 1/2 of one degree continuous operating (propeller shaft) angle.
