----- - PAGE 2 - -----
TOOLS REQUIRED- The following tools are necessary to service the KitchenAid Stand Mixer.
PHILLIPS SCREWDRIVERS- A Medium Size for numerous 8-32 x 5/8 screws used in Lower cover. A Larger Size will be needed on the 1/4-20 x 3/4 screws used to secure the Pedestal to the base. A Power Screwdriver is recommended for the larger screws.
STRAIGHT SCREWDRIVER- A Medium Size for removing the 10-24 x 1/2 Latch Bowl Spring and for adjusting the Bowl Clearance Adjusting Cam. A small size for removing the C Clip at the bottom of the Bowl Lift Rod.
SNAP RING PLIERS Used to remove the (2) Retaining clips from the top of the Planetary. Always wear Safety Goggles when using Snap Ring Pliers.
NEEDLE NOSE PLIERS Used for removing Hall Effect Sensor, Motor and Power Cord Leads from the Control Board Assembly.
DRIFT PUNCH- Used for removing the (2) Retaining Pins from the Planetary Assembly Shaft and Agitator Shaft.
SMALL HAMMER Used for the Light tapping force required to remove the (2) Retaining Pins discussed above.
VOLT-OHMMETER- For Diagnosis a Volt-Ohmmeter is useful in confirming continuity and an In-Line Wattmeter is particularly helpful in confirming Transmission drag problems.
POWER CORD REPLACEMENT Replacing the Power cord on the KitchenAid Professional 6 Mixer is an excellent way for the service technician to become familiar with the product.
The Power cord on this product must be replaced if it is damaged or abused in any way.
Before you begin, review the section in this manual on Disassembling the Gearcase and Planetary so you will be familiar with the removal of the Trim Band and Gearcase Motor Housing.
1. Gaining Access- Remove the Trim Band and the Gearcase Motor Housing Screws and set these parts aside.
The gearcase Motor Housing is a good place to store your fasteners. Always place the Gearcase Motor Housing on a soft surface to avoid scratching the paint.
At this point you should have (1) 8/32 x Ό Phillips Screw that held the Trim Band and (4) 8/32 x 5/8 Phillips Screws that secured the Gearcase Motor Housing.
2. Clear the Deck You will notice that the Lower Gear Case has a total of (9) additional 8/32 x 5/8 Phillips Screws that are used to secure the ground lug, control assembly, transmission cover and Motor.
Remove all of these screws from the Lower Gearcase in the following order (2) Control Assembly, (4) Transmission Housing, (2) Motor and (1) Power Cord Ground Lug.
NOTE-Carefully loosen the Transmission cover (do not remove) from the Lower Gearcase.
The Transmission cover is packed with grease and it is best to keep the cover in place after the mot has been removed. This cover will be loosened and tipped open later to free the motor.
3. Control Board Leads using Needle Nose Pliers, remove the Power Cord Leads from the Control Board.
----- - PAGE 3 - -----
4. Motor and Control Board Removal The Motor is still attached to the control Board by its leads and by the 3-Conductor Hall Effect Cable.
It is not necessary for you to remove these leads when replacing the Power Cord.
Carefully tip the Transmission Cover up to free the Motor Drive, then carefully lift the Motor/Control Board up from the Lower Gearcase Cover and set them aside.
5. Secure Transmission Cover After removing the Motor and control Assembly, temporarily secure the Transmission Cover by replacing the (4) 8/32 x 5/8 Phillips Screws.
This step will allow the service technician to rotate the Lower Cover for access to the Power Cord and not spill any grease.
6. Column Assembly Screws At this point the Power Cord is fully exposed an you can processed with the access by removing the (3) 1/4 - 20 x 3/4 Phillips Screws that hold the Lower Cover to the column.
These are larger than the 8/32 x 5/8 Screws and will often require a power Screwdriver to be loosened.
7. Power cord Replacement The old Power Cord can be freed from the Lower Cover by hand once the Column has been removed Always cut the old cord into small pieces and then dispose.
Follow these steps in reverse order after you have positioned the new Power Cord into the Lower cover.
CONFIRMATION Always test the Mixer for proper operation after replacing the Power Cord.
SERVICING GEARCASE AND PLANETARY
The Transmission Housing can be removed by hand after the (4) 8/32 5/8 Phillips Screws have been removed. Grasp the Transmission Housing securely and simply lift it upward. Be careful as the Attachment Hub Bevel Gear is in this Transmission Housing.
This Gear can be removed later by hand for inspection. Carefully set the Transmission on your paper towels after inspecting its condition.
Replace the Transmission Housing if cracks are evident. The Hall Effect Sensor Cable should be disconnected from the Control Board so that the Board can be moved away from the Transmission Housing.
Make sure that no grease comes in contact with the connector at the end of the Hall Effect Sensor Cable.
DRIVETRAIN TERMINOLOGY- Before Servicing the Gearcase lets review the rotating gears that make up the Gearcase. Additional details follow for servicing each of these gears.
The Planetary is free to drop after the Pin is removed.
The Technician should be aware of the three different Worm Gear Variations that have evolved with the product, as different replacement parts will be required, depending on the Date Code of the unit.
SEE: Worm Gear Assembly Variations Section.
Before removing the worm gear, notice that both bearings are oriented so the flats of the bearing are vertical.
