centre yoke.
)
- Use special tool bearing remover (MD998801) to remove the centre bearing assembly from the centre propeller shaft.
)
- Remove the DOJ boot from the DOJ assembly.
)
- Make mating marks on the outer race, cage and inner race, and then remove the circlip, outer race and ball.
NOTE: Note the positions of the balls so that they can be reinstalled in their original positions.
)
- Remove the inner race with cage from the centre propeller shaft assembly by using a puller (commercially available).
- Wipe off the grease and clean the outer race, inner race, cage and balls.
)
- Apply a thin coat of the specified grease to the ball grooves of the inner and outer races.
Specified grease: Repair kit grease
- Assemble the LJ assembly as follows:
- Assemble the outer race, cage, balls, and inner race with their mating marks aligned.
- Install the circlip.
)
- Apply specified grease to the LJ assembly.
Specified grease: Repair kit grease
Amount to use: 50 ± 5 g
Amount to use: 50 ± 5 g
)
- Apply a thin coat of specified adhesive to the groove side of LJ assembly (shown by arrows in the figure) and install the rubber packing.
Specified adhesive: 3M Stud Locking 4170 or equivalent
- Set the groove side of LJ assembly (for packing) toward the LJ boot side and install them.
)
- Lining up the mating marks on the LJ assembly and the centre propeller shaft and using the socket wrench, install the LJ assembly to the centre propeller shaft.
)
- Using the bolt, align the bolt holes of the LJ boot and the LJ assembly and install LJ boot to the LJ assembly.
- Install the rubber packing of the companion flange side in the same manner as described in (4) above.
- Apply a thin coat of the specified grease to the ball grooves of the inner and outer races.
Specified grease: Repair kit grease
- Assemble the DOJ assembly as follows:
- Assemble the outer race, cage, balls, and inner race with their mating marks aligned.
- Install the circlip.
- Apply specified grease to the DOJ assembly.

- Set the groove side of DOJ assembly (for packing) toward the DOJ boot side and install them.
- Lining up the mating marks on the DOJ assembly and the centre propeller shaft and using the socket wrench, install the DOJ assembly to the centre propeller shaft.
)
- Using the bolt, align the bolt holes of the DOJ boot and the DOJ assembly and install DOJ boot to the DOJ assembly.
- Install the rubber packing of the companion flange side in the same manner as described in (4) above.
)
- Clamp the boot by holding down the lever at a position nearly opposite to the vent groove provided in the DOJ boot (at arrow marked position on boot).
- Be sure to remove grease, if present, from around the vent groove. Grease obstructs the ventilation air passage.
)
- Set the centre bearing assembly in the direction shown in the figure and install it to the centre propeller shaft.
- Install, lining up the mating marks on the companion flange and the centre propeller shaft.
- While tightening the self-locking nut, install the centre bearing assembly with the companion flange.
)
- Set the centre bearing assembly in the direction shown in the figure and install it to the centre propeller shaft.
- Install, lining up the mating marks on the centre yoke and the centre propeller shaft.
- While tightening the self-locking nut, install the centre bearing assembly with the centre yoke.
)
- Apply multi-purpose grease to the following universal joint kit.
- Shaft and journal grease cup
- Dust seal lip
- Needle roller bearing
CAUTION CAUTION)
- Use special tool universal joint remover and installer (MB990840) to press the journal bearing into the centre yoke, sleeve yoke or flange yoke until the snap ring groove is fully visible.
)
- Use special tool to press the opposite side journal bearing into the yoke.
- Align the mating marks on the centre yoke and rear propeller shaft, and install the propeller shaft journal bearings in the same manner as described in (1) and (2) above.
)
- Use special tool universal joint remover and installer (MB990840) at the opposite side of the installed snap ring to press in the journal bearing toward the snap ring.
CAUTION)
