RUNOUT RUNOUT SPECIFICATIONS Front of Shaft 0.020 in. (0.50 mm) Center of Shaft 0.025 in. (0.63 mm) Rear of Shaft 0.020 in. (0.50 mm) NOTE: 1. Clean propeller shaft surface where the dial indicator will contact the shaft. 2. The dial indicator must be installed perpendicular to the shaft surface. 3. Measure runout at the center and ends of the shaft away from weld areas to ensure an accurate measurements. 4. Refer to Runout Specifications chart. 5. If propeller shaft runout is out of specification, remove propeller shaft. Index the shaft 180 degrees and measure shaft runout again. 6. If propeller shaft runout is now within specifications, mark the shaft and yokes for proper orientation. 7. If propeller shaft runout is not within specifications, check runout of the transmission/transfer case and axle. Cor- rect as necessary and repeat propeller shaft runout measurement. 8. Replace propeller shaft if the runout still exceeds the limits. STANDARD PROCEDURE PROPELLER SHAFT ANGLE This procedure applies to the front and rear propeller shaft, place Inclinometer 7663 on the machined ring of the pinion flange. To obtain propeller 1. Raise and support the vehicle at the axles as level as possible. Allow the wheels and propeller shaft to 2. Remove universal joint snap rings if equipped, so inclinometer base sits flat. 3. Rotate shaft until transmission/transfer case output yoke bearing cap is facing downward. NOTE: Always make measurements from front to 4. Place inclinometer (2) on yoke bearing cap (1) or pinion flange ring parallel to the shaft. Center bub- 3 - 4 PROPELLER SHAFT KJ |
