DRIVE TRAIN OVERVIEW - On a mixer that is
suspected of having been abused or used under
extreme duty cycles, take particular care in inspecting
alt of the gears before beginning reassembly.
The Drive Train is lubricated with approximately 2
ounces of #2 Grease.
All gears should have a light coating of this lubri-
cant applied prior to reassembly.
Grease collected in transmission cover should be
scraped out and reapplied to the gears.
* Attachment Hub Bevel Gear - After inspection
place this gear in the Transmission Housing.
Wipe any excess lubricant from the end that pro-
trudes through the Transmission Housing.
* Bevel Gear - This is the top gear on the Planetary
Shaft. The Bevel Gear is held to the Planetary Shaft
with a Snap-Ring.
This Snap-Ring must be removed with Snap-Ring
Pliers to remove the Bevel Gear.
* Worm Follower Gear - This is the bottom gear on
the Planetary Shaft.
The Worm Follower Gear can be removed from the
l E Planetary Shaft after the Bevel Gear and Retaining Pin
are removed.
* Worm Gear - This is the assembly that has the
bearings on each end of the Worm Gear Shaft.
This assembly can be lifted from the lower gearcase
after the Transmission Housing is removed.
When reassembling, remember to replace the
Thrust Washer on the end of the Worm Section and
that both brass bearings rest in the Lower Gear Case
with the flats of the brass bearings oriented vertically.
* Bevel Gear - The Bevel Gear should be removed
from the Planetary Shaft and set on the paper towel
with the other gears.
To continue the Drive Train tear down and inspec-
tion, the Pin on the Planetary Shaft must be driven out.
Be careful when completing this step as it is pos-
sible for the Planetary assembly to fall abruptly.
Simply keep the punch in the hole of the shaft while
the Pin is being set aside. Remove the punch after you
have secured the assembly with both hands.
Carefully push down to remove it from the base.
Again have the paper towel available and keep the
, grease away from other parts of the Mixer.
Since the Planetary Assembly is removed make
your inspection and use the following two step proce-
dure if disassembly is necessary.
1. Planetary Disassembly - if you see significant
wear or damage use Snap Ring Pliers to remove the
Retaining Clip from the Agitator Shaft.
You are again reminded as in the case of the
Retaining Clip that secures the Bevel Gear, wear
Safety Goggles whenever usiing Snap Ring Pliers!
The Pinion Gear on the Agitator Shaft can then be
removed by hand.
The Retaining Pin on the Planetary Shaft must be
removed to continue your inspection.
This pin can usually be removed with hand pres-
sure as shown below.
Notice the washer under the Pin. Be sure to re-
place it correctly during reassembly.
The Agitator Shaft can now be removed from the
Agitator Assembly and inspected or replaced as nec-
essary.
2. Planetary Pinion Gear - Inspect the Agitator
Shaft and Planetary for any damage.
Make sure that the Lower Retaining Clip on the
Agitator Shaft is in good condition.
Place the Agitator Shaft into the Planetary.
The Agitator Shaft should rotate smoothly once
inside the Planetary.
Place the Thrust Washer on the shaft and then
position the Retaining Pin into the hole at the top.
The Planetary Pinion Gear has a sloton the bottom
that sets over the Retaining Pin.
Set the Planetary Pinion Gear on the shaft cen-
tered over the Retaining Pin.
Using Snap Ring Pliers, install the Retaining "C"
Clip to the top of the Agitator Shaft.
e Worm Follower Gear Removal - The Worm
Follower Gear that links to the Worm Gear Assembly
can now be lifted from the bottom of the Mixer Cover.
The Worm Gear Assembly, has two brass bear-
ings on each end and can be lifted from the Bottom
Cover with hand pressure.
The collection of Gears can be cleaned with a
benign Solvent like WD-40 and then inspected. -
Any gear showing signs of galling, nicks, cracks or
noticable wear should be replaced.
The (2) Worm Gear Assembly Bearings and Thrust
Washers should also be replaced if noticable signs of
wear are observed.

TESTING THE CONTROL ASSEMBLY - The
Control Assembly should first be tested with the Mixer
in the "Off" position and disconnected from the AC
Mains.
NOTE: Before you begin this test check the condi-
tion of the Stand Mixer Power Cord and replace it if it
is damaged or defective.
e Simply move the Handle from the "Off" position
and observe each of the six speed detents.
* These should have a distinct locking action in
each of the six running positions.
* Now return the Mixer to the "Off" position and
plug it into the AC Supply.
The Mixer should not run in the "Off" position.
NOTE: The mixer must be in the "Off" position
for 5 seconds - in order to Reset.
* Carefully move the Controlto the first "Stir" speed
and confirm operation.
* Remember that ALL Speeds have a "Soft Start"
feature that automatically starts the Mixer at a slower
speed to help prevent "Splash Out".
* You should observe a slight pause as you move
' from each speed. Confirm the operation at each of the
six (Stir -2-4-6-8-10) detents of the Control.
REPLACING THE SPEED CONTROL - If replace-
ment of the Control Assembly is necessary, make sure
that the Mixer is unplugged from the AC Mains and
after removing the Motor Housing, remove the (2) 8-32
x 5/8" Phillips Screws that hold the Control Assembly
to the Lower Cover.

Leads, the (2) Power Cord Leads and the Hall Effect
Sensor Connector from the Circuit Board..
* Using the replacement Control Assembly,
reconnect these leads to the appropriate points on the
Circuit Board.
