SERVICING THE PLANETARY SETS 

 

 

1.

 

Remove the retaining rings from the planet pins.   

 

2.

 

Remove the pins from the carrier by carefully tapping them out.   

 

3.

 

Remove the planet gears, washers and bearings from the carrier.   

 

4.

 

Inspect the pins, bearings, and gear bores for evidence of wear and replace if necessary. 

 

5.

 

On output planet gearsets, note that two bearings with a spacer between them are used. 

 

6.

 

Before reassembly, be sure to insert the thrust plate into the carrier.  

 

7.

 

To reassemble, be careful to line up the planet pins with the thrust washers and bearings  then 

press the knurled part of the pin into the carrier.  If the pins are not lined up properly, the 

washers can be shattered during the pressing operation.
