1. Model Name:  MX6240N – MX7040N 
 
2. General:   
On the early machines that were mass-produced, some bearing mounted on the drum  
 
 
 
fixing sleeve insertion opening might be rusty.  
 
 
 
If it gets rusted, it might be hard to insert and remove the drum fixing sleeve. 
Once it gets rusted, it becomes hard to insert and remove the drum fixing sleeve but there is no 
impact on its performance. 
3. Detailed  
Solution:   
Up to the middle of the September 2012 production, apply 2-rice-grain sized grease  
 
 
 
(UKOG-0158FCZZ) to the drum fixing sleeve at the machine installation. 
 
 
 
After the middle of the September 2012 production, the drum fixing sleeve will be greased  
 
 
 
in production. 
 
 
 
 
If the bearing is so rusted that it is very hard to insert and remove the drum fixing sleeve,  
 
 
 
place an order of the service part bearing (NBRGY0988FCZZ) and replace it. (See the  
 
 
 
attachment.) 
 
 
 
 
Once some water, sweat, etc. gets stuck on the bearing attached to the drum fixing  
 
 
 
sleeve insertion opening on the DV unit, it might get rusted and be hard to insert and  
 
 
 
remove the sleeve. 
 
 
 
So please handle the DV unit with extra care not to touch the bearing attached to  
 
 
 
the drum fixing sleeve insertion opening in fields.
