Component Tests and General Diagnostics

INSPECTION

NOTICE: When performing operations which involve the removal and installation of the propeller shaft, always check the joint angle. Make adjustments if necessary.

1. STABILIZE PROPELLER SHAFT AND DIFFERENTIAL
a. Turn the propeller shaft several times by hand to stabilize the center support bearing and flexible couplings.
b. Using a jack, raise and lower the differential to stabilize the differential mounting cushion.
2. CHECK NO.2 AND NO.3 JOINT ANGLE





a. Using SST, measure the installation angle of the intermediate shaft and propeller shaft.
SST 09370-50010

HINT: The SST should be directly underneath the tube.





b. Using SST, measure the installation angle of the differential.
SST 09370-50010

HINT: Measure the installation angle by placing the SST in the position, as shown in the illustration.





c. Calculate the No.2 joint angle.








d. Calculate the No.3 joint angle.





If the measured angle is not within the specification, adjust it with the center support bearing adjusting washer, differential mount upper stopper and adjusting shim.

3. Example SC400: HOW TO READ ADJUSTMENT CHART
a. Take measurements, then calculate the No.2 and No.3 joint angles.
a. Mark the calculated values on the chart and read the coordinates.
c. Replace the adjusting washer, shim and mount upper stopper in accordance with the coordinates read and adjust the joint angles.





Example
Measurements (Installation angle):
Intermediate shaft: 1°10'
Propeller shaft: 2°45'
Differential: 1°44'
Joint angle:
No.2: 1°10' - 2°45' = -1°35'
No.3: 2°45' - 1°44' = 1°01'





Adjustment (Center support bearing):
Standard parts 6.5 mm (0.256 inch) + 2.5 mm (0.118 inch) = 8.5 mm (0.138 inch)
Use an adjusting washer which is 8.5 mm (0.335 inch) thicker.
Adjustment (Differential): Use an adjusting shim which is 1.0 mm (0.039 inch) thicker.








HINT: Maintain the same thickness for the adjusting washers and adjusting shims on both the left and right sides. If a washer, stopper and shim of the exact thickness are not available, use the parts which are nearest in thickness.








NOTICE: Check the joint angle once again after making the adjustment.
