On a KSB5WH4 how to remove & replace clutch?

Yes fixable a number of ways

Remove the blades and punch out the shaft. Clean it all and then reassemble it with lots of water pump grease (it's waterproof). Seizing happens because liquid goes down between the shaft and housing and sets.

Or

You can replace the blade assembly. The link below shows unavailable, but it shows the screw cap.

From Kitchen Aid they only come on a new motor. I am a Kitchen Aid service agent and I remove them from burnt out motors and keep them. Look for a service agent near you and see if they can help you out. I have no idea where you are, I'm in New Zealand.

here is a solution that worked for me (see below)....to get the clutch out I used a flat-head screw driver in the bottom of the base to hold the cooling fan and then screwed the clutch out with a clockwise turn. I have yet to order a new clutch ($2.70) at http://www.ereplacementparts.com/waring-bb180blender-parts-c-120019_120020_130537.html but the removal works. Good luck.

Hello
There are two type of fittings for this gear. In some models it will be push in type, and for others it will be screw type. If your model has push type one, just pull out it from the shaft. You may have to excert a strong force to pull it out. If it is screw type, you have to open its lower lid by unscrewing its secrews, hold the cooling fan and hold the gear at the top, twist it in 'CLOCKWAYS' direction, [not counterclockwise], to screw it out. OK.

Grab the blade with a rag so you don't cut yourself, then grab the clutch with another rag and turn CLOCKWISE. It's threaded reverse - took me hours to figure this out. I found grabbing with rags or maybe towels worked the best. That should work

The clutch assembly is for the teeth on the base itself. If your problem is with the teeth that are connected to the bottom of the blade that sits in the jar, you want to order a blade assembly instead.

I had the same problem and I manaed to fix my Cuisinart SmartPower Duet blender. There are two thermal fuses, one tape attached to each stator winding. Both of mine were blown.

In addition, when the fuses blew, it must have spiked the triac. I had to replace mine. It's the black 3-legged transistor looking device with a small metal heatsink attached to it. This gizmo directly throttles the power to the motor under control of the microprocessor. There are some guides on the internet on how to test it.

Also, the clutch was very hard to remove and needs to be removed to more easily replace the thermal fuses. I clamped down the end of the motor shaft to a bench vise real hard and then I used a 7/8-inch open-end wrench to wedge into the clutch prongs which made it much easier to apply torque. Remember that its screw threads are reversed from normal screws so that it does not unscrew during operation. You have to turn it counter-clockwise to unthread it.

Hope that helps!

I managed to fix my Cuisinart SmartPower Duet blender. I had the same problem, lights and buttons work, but no motor action. There are two thermal fuses, one tape attached to each stator winding. Both of mine were blown.

It took about 1-1/2 hours and definitely needs to be done by someone who knows their way around electronics. Hope that helps!

huh?

These little jewels are threaded onto the motor shaft so they tighten up when in operation. To remove, you will have to immobilize the motor shaft. See if you can insert an icepick or screwdriver into the blades of the motor fan on the bottom. Then using a punch and hammer, gently tap the clutch disk in the direction opposite from its normal rotation.

BE CAREFUL not to use so much force that you break either the clutch disk or the motor fan blade.

Remove the little rubber feed on the bottom of the base (they might be glued a bit so be careful not to rip them). This will reveal 4 phillips head screws...remove them...this will open the base and reveal the back site of the rotor. In the middle you will see a turban blade like wheel with a large flat tip screw. Wedge a large screwdriver between the teeth of the old clutch so that when you turn the flat tip screw it will stop rotating the other end. Turn the screw with some force to the right to losen the clutch...then do the reverse to get the new one on tight...put everything back together and there you have it.

Keep in mind that this might void your warrenty if you still have some on it.
