STEP 5 

Now we must connect our reassembled nose section to 
the main RDH Body.  First, secure and compress the 
large C-Clip at the bottom of the nose section with a 
large Zip-Tie, (larger ones work best).   
 
 
 
 
 
 
 

STEP 6 

Once you have secured and compressed the large C-Clip, 

carefully lower the nose section 
onto the motor assembly, which 
should be secured, once again in a 
9/16” collet. 
 
Lower the nose section until the 
C-clip slips into the upper edge of 
the main RDH body and the Zip-
Tie has been pushed up to the 
main knurled edge of the nose 
section.  Then, simply cut the Zip-
Tie loose with an exacto knife and 
firmly push the nose section all the 
way into the main RDH body. 

 

STEP 7 

Your Midwest RDH Should now be fully assembled and ready to 
test.  Many times, the colored rubber band at the bottom of the 
motor will be missing or in poor condition.  Replacing this band 
improves the look of the handpiece greatly and we recommend 
this addition with most RDH repairs. 
 
The bands are part# 40422RDH and come in several colors.
