17. Put some drops of high-quality 

 approved oil (MIL-L-6085A, MIL- 

 L-8704A, MIL-L-644A) with a vis- 

 cosity index of 70 into the 

 bearing in the stator mount. 



18. Insert armature with field in 

 place into the stator mount. 

 Avoid pushing the armature out 

 of the field (see 14). 



19. Secure the field with the four 

 socket-head screws. 



20. The armature is in place when 

 the distance from the field sur- 

 face to the bottom of the recess 

 in the armature is 0.040 ±0.005 

 inch. NOTE: Take measured 

 values from opposite places and 

 use mean value, because the 

 armature is normally canted in 

 relation to the field by mag- 

 netic forces. 



21. Get one socket-head screw out. Put Loctite 290 adhesive/sealant on the 

 thread and torque the screw down. Then proceed until all four screws are 

 locked.
