14. Put a few drops of high-quality approved oil (see 

 step 7) in the wave generator and onto the teeth 

 of the flexpline. 



15. Install the wave generator with the flexpline 

 into the dynamic spline (fastened to the retainer 

 ring) so that the teeth mesh concentrically. Check 

 this visually or with a feeler gauge. 



16. Put the circular spline on the flexpline so that 

 the teeth mesh concentrically. Check this visu- 

 ally or with a feeler gauge. 



ASSEMBLY 



It is essential that the C/S and F/S toothmesh concentrically engage for 

 proper function as noted below. The unit will function in what is de- 

 fined as the "dedoidal" state but will be subject to reduced life. 



MINOR AXIS 

 CONCENTRIC DEDOIDAL 



When the toothmesh is exposed, a visual or feeler gage check for equal 

 tooth clearance (A) is made as noted above.
