Sub Assembly B Reassembly (Motor Section) 

 

STEP 13 

Place the turbine raceway upside down on you work surface.  Insert 
the front turbine bearing into the appropriate hole (as shown).  With 
the bearing partially inserted, place a small dab of Loctite on the tip 
of a needle and apply sparingly under the flange of the bearing.  
Press the bearing firmly into the drive ring raceway and let sit. 

 

STEP 14

 

After the Loctite has cured, center the raceway, bearing side down, over 
Hole# 7 in your work block (picture at left).  Place the turbine spindle over 
the hole in the bearing with the fat side up.  Put your Lares assembly punch 
in the top of the spindle and press the spindle into the bearing. 

 
 

 

STEP 15 

Now center the impeller over Hole# 6 in your work block. Place the small 
end of the turbine spindle into the impeller (as shown).  Using the same 
Lares punch, press the spindle into the impeller.  

 
 
 

 
STEP 16 

If you did not replace the rear o-ring in 

STEP 10

, do so now.  Then reinstall the vent 

plug. 

 

STEP 17 

Place the rear turbine bearing (40405C) into Hole # 2 of your work block.  
Be sure the balls in the bearing are face down.  Put the small end of the 
turbine spindle into the bearing.  Use the Lares punch to press the partial 
turbine assembly into the bearing. 
 

 

STEP 18 

Insert the raceway tool into the three holes in the raceway.  Carefully begin to thread the 
raceway into the motor housing.  A good tip is to turn the raceway counterclockwise until 
a click is heard.  Then begin to thread the pieces together.  Once started, thread the 
raceway securely into the housing until it bottoms out.  

 
STEP 19 

Now insert the two narrow drive rings into the drive 
ring raceway 180 degrees apart.  Notice there is a 
small cut out portion on the inside edge of the drive 
ring raceway.  This allows you to insert the narrow 

drive rings into the proper position.
