	3. The pinion assembly may now be assembled to the propeller shaft by pressing the splined end into the coupling on the end of the propeller shaft so that rivet hole in the pinion shaft lines up with the hole in the propeller shaft. Insert a new rivet in this hole and rivet over both ends. 4. Tighten the bearing lock nut and lock it in the milled slot in the pinion shaft. Differential Assembly 1. Examine both differential side gear bearing surfaces in the differential case; also the backs or thrust surfaces for these gears and the differential pinion gears. 2. Check both differential side bearings for roughness after they have been thoroughly cleaned and oiled. 3. Remove the lock wire from the ring gear bolts and check each bolt to make sure they are all tight. 4. Inspect the differential side gears for scored hubs or thrust surfaces. Examine the internal splines and check their fit on an axle shaft.	Differential Bearing Replacement The differential side bearings are a press fit on the hubs on each side of the differential case. These bearings must be removed and replaced as follows: 1. The legs of differential bearing puller, TR-278-R, should be fitted into the two notches in the case and the clamp screw tightened, Turning the puller screw will remove the bearing without damage to either the bearings or the case, Fig. 8. 2. After the bearings have been removed, they should be thoroughly cleaned, oiled and then checked for roughness.


		Fig. 9—Replacing Differential Bearings 3. To replace the differential side bearings, place them on the hubs with the thick side of the inner race toward the case and drive them in place with J-994 differential side bearing replacer, Fig. 9. Ring Gear Replacement 1. Remove the bolts. The ring gear may then be tapped off the case with a soft faced hammer.
