26. Put a few drops of high-quality ap- 

 proved oil (see step 7) into the 

 angular contact ball bearing. 



27. Slip one spacer on the shaft from the 

 brushring side. 



28. Very gently insert the motor bearing 

 unit in the inner housing. Make sure 

 that during the insertion the motor arm- 

 ature does not move out of the motor 

 field (this would bend or destroy the 

 brush springs). Make sure the wires 

 don't touch the brush springs or the 

 armature. Make sure the wires don't 

 remain between the ball bearing and the 

 spacer. Make sure the holes in the re- 

 tainer ring match with the holes in the 

 inner housing. - Your first try will 

 probably fail, so try again. Patience 

 is required. 



29. Remove the two temporary pins. Make 

 sure that during the following assembly 

 the motor armature does not move out of 

 the motor field! 



30. Screw the retainer ring and inner hous- 

 ing tightly together with the six 

 socket-head screws. 



31. Take one screw out. Put Loctite 290 

 adhesive/sealant on the thread and re- 

 place the screw tightly. Proceed until 

 all screws are locked. 



32. Press the Reali-Slim ball bearing 

 (Kaydon bearing no KA 030 XPO) onto 

 the inner housing so that the non- 

 interrupted part of the bearing 

 separator faces to the coil on the 

 inner housing. Make sure not to 

 transmit pressure or impact through 

 the rolling elements of the bearing 

 while pressing it onto the inner 

 housing. 



33. Put a few drops of high-quality ap- 

 proved oil (see step 7) into the gap 

 between flexpline and circular 

 spline and into the Kaydon ball 

 bearing.
