The bottom of my pitcher is leaking the stainless steel blade is loose

there is a wrench (by Vitamix) for under $10. you can get it from amazon. it makes the job of removing a blade assembly much easier.

it is worn out,time for a new one,it may be too tight too Waring 2 Speed Blender Stainless Glass 51BL29 Classic Retro

If what you can't see in your device, namely the motor assembly, it may be that the assembly is one of those not designed to be taken apart and that it is wearing out. If so, that could be the cause of the looseness you are experiencing. It may be unrepairable or more costly to fix than to replace. Twenty plus years is a good run for almost any mechanical device.

The jar assembly for the KSB540 is part W10503762. this is for the 48oz jar assembly. Here is a link to the product KitchenAid Blender Jar Assembly for KSB465

You can also use the 56oz jar on your blender, which is part number W10555711, here is a link to that product as well: KitchenAid Blade Jar Assembly W10555711

Make sure the blade assembly is put together in the correct order. The blade needs to go through the gasket so that the order is pitcher glass, gasket, and metal blade base. Then the final plastic cap threaded onto the pitcher. If the gasket is not between the pitcher and the metal blade assembly, you will have leaks.
Also, check the gasket to be sure it's not cracked and that it doesn't have residue on it.
I hope this helps. If it does, please come back and rate my suggestion!

the older glass jar blenders were sold as a complete ***'y too.
no separate parts were available. i'm sure the stainless jars are sold in the same way...complete.

Depending on the age of your blender, a new blade assembly may be available. I would recommend calling Kitchenaid Customer Service for pricing. Their toll-free telephone number is:

I actually have the pitcher, it comes w/the chigger and the blade that connects to the bottom of it.

this part is brand new, let me know if you still need one.

I was just able to fix mine. You'll need the following: two wrenches (almost any type), steel wool, and vegetable oil.

1. Clamp the hexagonal nut inside the bottom of the pitcher with one wrench and place the jaws of the other wrench between the "spokes" of the wheel at the outside bottom of the pitcher.
2. Turn either counter-clockwise until the hex nut comes off. At this point, you should be able to pull the bottom piece out from the bottom. Pay attention to the order and orientation of the parts inside the pitcher as they may fall out now.
3. Dry off the shaft and rub it with some ordinary steel wool (think SOS pads).
4. Twist a small amount of the steel wool and run it back and forth through the hole the shaft goes through.
5. Wipe both clean with a clean cloth or napkin.
6. Rub a little vegetable oil on the shaft.
7. Place the shaft back in the hole and test the movement. It should be like new again.
8. Reassemble the blender.

Hope this helps,

John

You can replace the Osterizer "Standard Blade Assembly" (which includes a new rubber gasket) without buying a new and expensive glass jar. See http://www.householdappliance.com/blenderparts.html or one of the other appliance repair parts websites. After 20 years of use, it's time for a new blade and bearing.
