22.Select the thrust race number 8 with the following 

procedure:

(1) Fix a dial gauge to special tool MB991603.
(2) Push the direct planetary carrier,and the direct annulus 

gear  in alternately, and then measure the end play of 
direct planetary carrier.

NOTE: When pushing the direct planetary carrier  in, take 
care that the center support does not move. 
NOTE: When pushing the direct annulus gear  in, use the 
special tool MB998304.

(3) Reinstall by selecting the thrust race number 8 installed 

by the procedure (19) so that the end play of  direct 
planetary carrier becomes the standard value. 

NOTE: Refer to the thickness recorded in step 12.

Standard value: 0.25 

− 0.55 mm (0.0098 − 0.0217 inch)

(4) Measure the end play again, and confirm that it is within 

the standard value.

NOTE: Carry this step out with special tool MB991603 
and dial gauge installed.

23.Using the following steps, select the snap ring for fixing the 

center support.

(1) Install the snap ring used for fixing the center support 

used.

(2) After pushing the direct planetary carrier,and the center 

support in alternately, and then measure the end play of 
center support.

NOTE: When pushing the direct planetary carrier in, be 
sure to push them in to the point where the center sup-
port touches the snap ring.

(3) Select the snap ring for fixing the center support 

installed in step 23 (1) so that the end play of the center 
support is at the standard value. Then, reassemble.

Standard value: 0 

− 0.16 mm (0 − 0.0063 inch)

(4) Measure the end play again, and confirm that it is within 

the standard value.

24.Using the following steps, select the snap ring for adjusting 

the brake reaction plate end play and second brake end
