7. For all prop systems perform the first measurement:
a. Rotate the prop shaft to align the rear-most yoke
flanges vertically.
b. Install the J 23498-A, or equivalent to the lower
U-joint bearing cap of the rear-most yoke. This
yoke may be part of a prop shaft, torque tube
input shaft, or a drive axle pinion shaft. Measure
and record the angle of the shaft.
8. For prop systems with 2 or 3 U-joints, perform this
additional measurement:
Without rotating the prop, install the J 23498-A, or
equivalent to the lower U-joint bearing cap of the
forward-most, vertically-aligned yoke. This yoke may
be part of a prop shaft, transmission output shaft, or
a transfer case output shaft. Measure and record the
angle of the shaft.
9. For all prop systems perform the second
measurement:
a. Rotate the prop shaft 1/4 turn to vertically align
the flanges of the forward yoke that mates to the
rear-most yoke.
b. Install the J 23498-A, or equivalent to the lower
U-joint bearing cap of the forward mating yoke.
This yoke may be part of a prop shaft,
transmission output shaft, or a transfer case
output shaft. Measure and record the angle of
the shaft.
10. For prop systems with 3 U-joints, perform this
additional measurement:
Without rotating the prop, install the J 23498-A, or
equivalent to the lower U-joint bearing cap of the
forward-most, vertically-aligned yoke. This yoke may
be part of a transmission output shaft, or a transfer
case output shaft. Measure and record the angle of
the shaft.
11. Remove the J 23498-A, or equivalent.
12. Install any U-joint bearing cap snap rings that were
removed prior to installing the J 23498-A, or
equivalent.
13. Calculate the U-joint working angle at each
intersection of two shafts.
Subtract the larger number from the smaller to obtain
the working angle. For example: If the drive axle
pinion has an angle of 16 degrees and the
connecting propeller shaft has an angle of 13
degrees, then the working angle of that intersection
is 3 degrees.
14. For prop systems with 1 U-joint; compare the
working angle to the following specification
guideline:
Specification Guideline
Prop systems containing only 1 U-joint: The U-
joint working angle should be between 1/2 and 3/
4 degrees.
15. For prop systems with 2 or 3 U-joints; compare the
difference between the working angles of the
cancelling U-joints to the following specification
guidelines:
Specification Guideline
Allowable range of difference between
cancelling U-joint working angles: 0.25 to 1.0
degrees
16. For prop systems with 3 U-joints; compare the
working angle of the odd, or non-cancelled U-joint to
the following specification guideline:
Specification Guideline
Prop systems containing 3 U-joints: The odd, or
non-cancelled U-joint working angle should be
between 1/10 and 1/2 degrees.
17. Any working angle that is not within the specification
guidelines requires adjustment.
