STEP 11 

After the housing has been secured to the base piece, reinsert the motor nose assembly, 
parts 1 thru 5 from the Exploded View 1 picture.   Please remember to call the corporate 
office if you need any help on this or any other step. 
 

STEP 12 

Now that the 
motor has been 
reassembled we 
will look at the 
nose section 

repair process.  Remember to only disassemble the nose section if there is a problem with 
the top gear.  None of the internal shaft bushings are available. 

 

STEP 13 

Place the nose section on a pair of V-blocks and locate the 
gear retaining pin.  Now that you have located the pin, tap 
it out using a small thin punch.  Remove the gear and 
replace it with a 60219 gear and 60219A retaining pin.  

 
The above picture shows the disassembled nose section.  The top gear is replaceable, but 
the main shaft is not, so be careful when handling the shaft.  You can use your Midwest 
Nosecone Tool (00014) to gain access to the shaft. 
 

STEP 14 

The last step deals with meshing the nose assembly and motor assembly back together.  
Secure the threads of the motor in a 9/16” collet.  Then lower the nose section down over 
the motor until it rests on the large retaining clip.  Half-cock the nose section so that part 
of the retaining clip is feeding down into the top of the motor housing.  Then, while 
applying downward pressure, press the final edge of the clip into the housing with a small 
flat screwdriver.
