Krups blender drive gear

One of the driving clutch parts is slipping, it will be either the coupling on the motor or the one on the blade. Sometimes a repair can involve replacing both as it is possible for one to damage the other.

take a flat head screw drive to the bottom of the blender and us it to hold the blender shaft in place while you turn the gear by hand or with a plyers (it is reverse threaded) and it should spin right off. when you get the new on it should spin right on.

The body of the blender is held together by three cross head screws two at the base which are clearly visable and a third which is concealed by the pulse on/off switch which you need to prise off to reveal - small spring to rear to catch! Our blender went totally dead due to a blown internal fuse which I have now replaced and hey presto we are back in action.

Like you, I am all for repairing and keeping the world free of blenders that only need one part replaced. The rubber coupling was easily ordered online, the challenge I later found was to remove it without losing my sanity. After messing up the side grill of the blender pretty good, I realized there is an opening on the motor casing that allows access to a "gear" that is firmly attached to the axle where our little friend will hopefully screw on and restore the contraption to a working state. In order for you to see (which I must warn you, it's not much of a view) through the grill you will need a flashlight or book light. Towards the top of the aforementioned gear (not the rubber part) there is a groove in which a flat screwdriver can easily fit immobilizing the axle and allowing you to easily unscrew it. Oh, but wait, I forgot this is the faulty part and it will spin without the slightest torque on the axle thus never loosening or getting it unscrewed. My solution to this problem was to surgically remove as much rubber as possible to allow me to attach my vise grip to the nut and finally put this thing out of its misery. Using the same procedure of inserting the screwdriver to immobilize the axle I was able to screw the new part and voila the blender is fixed!!!!

I carved off the rubber with a knife; inserted a flathead screwdriver throught the slot in the bottom to hold the gear in place; using pliers I unscrewed (COUNTERCLOCKWISE) the rubber gear.

You can most likely find all kind of blender parts at www.thegourmetdepotco.com. I just bought a Krups blender rubber drive gear from that online store. It's the best lowest price, compared it to Amazon.com too. Try it.

Repairing the blender:
My guess: You worked the motor too hard on your last blending session and it overheated. That will cause a thermal fuse inside to cut off. The blender won't work again until you replace the fuse but otherwise it should be fine. The fuse looks like a white diode and it will be attached tightly to the motor with a nylon strap (so that it can pick up the heat of the motor). The leads to the fuse are shielded with heat resistant nylon wrap. You will need to remove the rubber drive gear in order to remove the plastic house so you can work, although if you are really handy you might be able to at least test the unit by only removing the plastic bottom on the base unit.

To remove the plastic housing, remove the little rubber feet and then remove all of the screws on the bottom of the unit. You may need to buy a bit set for tamper resistant screws (I ***hate*** those), I don't remember. When the bottom is removed, you will see that the there is a screw head on the bottom of the central motor shaft. You can use a screw driver here to hold the motor from turning, then you can carefully use a pliers to unscrew the rubber drive gear on the top of the base unit (try not to damage the rubber). With the gear removed you can get access to the wires.

To test the fuse unit, just check its continuity. Short=good, open=bad. To further test, short out the fuse with a jumper cable and your blender should work.

EPO (Electronics Parts Outlet) in Houston, TX, has the replacement fuse unit. I don't know that they like mail order.

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.

it's not easy. you will need a set of pliers, a flathead screwdriver, and a phillips screwdriver. first, remove the 4 rubber plugs from the bottom of the blender (just work them out with your fingers). second, use the phillips screwdriver to unscrew the 4 screws that were under the ruber plugs. the blender should come apart. right in the bottom center on the inside of the blender you should see a steel rod with a groove in it. this rod will run all the way to the top and be connected to the rubber gear drive on top. get a firm grip on the rubber gear drive with your pliers. place the flathead screwdriver into the groove of the steel rod and unscrew. it will be very tight, but eventually, it will give. you will most likely destroy the old rubber gear drive in the process, but the idea is to replace that one anyway. good luck!
