25. Press the Reali-Slim ball bear- 

 ing (Kaydon bearing no KA 040 

 XPO) on the inner housing so 

 that the noninterrupted part of 

 the bearing separator faces to 

 the coil on the inner housing. 

 Make sure not to transmit pres- 

 sure or impact through the roll- 

 ing elements of the bearing 

 while pressing it onto the inner 

 housing. 



26. Install the wave generator into the flexpline, as shown. 



27. Put a few drops of high-quality approved oil (MIL-L-6085A, MIL-L-870A, 

 MIL-L-644A) with a viscosity index of 70 into the Kaydon bearing and 

 into the wave generator. 



WAVE GENERATOR ASSEMBLY (W/G) 



The W/G is provisioned with an Oldham-type flexible coupling 

 and consists of parts shown in the exploded view. Disassem- 

 bly as required for hub mounting is permissible, together 

 with reverse mounting if desired. 



WASHER 



The hub portion of the W/G must be torsionally and axially 

 affixed to an input shaft. Overhung input shaft loads caused 

 by gears, sprockets, etc, require a suitable two-bearing shaft 

 support, as noted below; otherwise, one Ibearing to axial- 

 contain the W/G assembly is permissible.
