GENERAL INSPECTION

OUTPUT SHAFT AND PRIMARY SUN GEAR SHAFT

1. Inspect the thrust surfaces and journals for scores. Inspect the internal gear for broken or worn teeth.



2. Inspect the aluminum sleeve for scores or leakage. Inspect the ring grooves for burrs.



3. Inspect the keyway and drive ball pocket for wear, and inspect the splines for burrs or wear.



4. Inspect the output shaft sleeve for alignment with the governor drive ball (Fig. 7).


(FIG. 8 - Checking Output Shaft Snap Ring Clearance)


5. . Inspect the external parking gear teeth for damage and the speedometer drive gear teeth for burrs.



6. If either the output shaft or ring gear has been replaced, place the assembled unit with the gear face down on the bench, push the shaft downward, and check the clearance between the top of the snap ring and its groove (Fig. 8).
   
   If this clearance exceeds 0.002 inch, replace the snap ring with a thicker ring to reduce the clearance to less than 0.002 inch. Selective snap rings are available in several thicknesses for this purpose.



7. Inspect the rubber seal and stop ring at the front of the output shaft spline. If wear or damage is evident replace the seal.



8. Inspect the primary sun gear for broken or worn teeth. Inspect all thrust surfaces and journals for scores. Check all fluid passages (Fig. 9) for obstructions and leakage. Inspect the seal ring grooves for burrs.



9. Inspect the sun gear shaft splines for burrs and wear. Check the front clutch lubrication valve for free movement.

SPEEDOMETER CABLE REPLACEMENT

To replace the speedometer drive cable, disconnect the cable housing at the speedometer, and pull the cable out of the housing. Lubricate the new cable with cable lubricant B5A-19581-A and insert it all the way into the housing, and twist it slightly to make sure that the squared drive is engaged in the speedometer driven gear.

The housing is fastened to the transmission as shown in Fig. 24. If a speedometer cable is broken, it will be necessary to disconnect both ends of the cable housing in order to remove the broken sections.

The speedometer driven gear is held on to the speedometer shaft casing by a retainer clip. When replacing the driven gear, make certain that the gear is secure by placing the gear in position before inserting the retainer clip through the gear slots.
