Propeller Shaft Angle

PROPELLER SHAFT ANGLE
This procedure applies the front and rear propeller shafts.
1. Place vehicle in neural.
2. Raise and support vehicle at the axles as level as possible.
3. Remove universal joint snap rings if equipped, so Inclinometer 7663 base sits flat.
4. Rotate shaft until transmission case output yoke bearing is facing downward.

NOTE: Always make measurements from front to rear and from the same side of the vehicle.

5. Place Inclinometer 7663 on yoke bearing (A) parallel to the shaft. Center bubble in sight glass and record measurement.
This measurement will give you the transmission yoke Output Angle (A).
6. Rotate propeller shaft 90 degrees and place inclinometer on yoke bearing parallel to the shaft. Center bubble in sight glass and record measurement. This measurement can also be taken at the rear end of the shaft.
This measurement will give you the Propeller Shaft Angle (C).
7. Rotate propeller shaft 90 degrees and place inclinometer on companion flange yoke bearing parallel to the shaft. Center bubble in sight glass and record measurement.
This measurement will give you the Pinion Flange Input Angle (B).
8. Subtract smaller figure from larger (C minus A) to obtain Transmission 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. 4) for additional information.

RULES
^ Good cancellation of U joint operating angles should be within 1 degree.
^ Operating angles should be less than 3 degrees.
^ At least � of one degree continuous operating (propeller shaft) angle.

TWO/THREE PIECE PROPELLER SHAFT





The procedure to measure the propeller shaft angles involved with a two/three piece (Fig. 5) propeller shaft is the same as those for a one piece propeller shaft.
