My kenmore blender blade is broken, so am looking for blade assembly base to buy, my model number is KMB048 (238.68928)

Turn the cog in the base a little. Sometimes it gets misaligned.

Check the blade assembly if it is loose tighten it up. If it is worn out or cannot be tightened up then buy another jug complete with blade. If it is the glass jug model then the blade assembly is available without the jug and they also have a replaceable seal at the base.

Hiya,

Sorry you are experiencing an issue with your blender. Sadly you will have have to replace the whole blade assembly in this instance.

Please see our help video for your perusal.

I hope we could help you resolve your issue :-)

The ring itself is not available separately, you need the blade assembly part number 123250-000-000 available from Sunbeam at 1-800-458-8407.

You need to unfasten the white base from the clear jug, then the rotating blade will sit inside the white base, with the blade facing upwards. The white rubber flange goes in next. Then screw the assembled base back into the clear jug. The jug should then fit on to the stand.

The seal on the rotating shaft has either worn out or hardened and if constructed like most, the seal cannot be replaced since the chopping blade and shaft are permanently fastened together. Your only recourse is to buy a new blade assembly which should be available.
I would search for it with the model number of the blender and 'cutter' or 'blade' assembly.

check with abtec.com. They seem to have parts for the Hamilton Beach model 50754 blender but I seem to remember the blade and base come as one unit.

I'm going to super glue the crack that is causing mine to leak.

Look at the underside of the blade shaft. The metal wing nut on the end of the shaft secures the blade assembly to cream coloured plastic blade base. The wing nut also transmits the drive from the rubber coupling on your blender to the blade shaft. The wing nut has a LEFT HAND thread.
The left hand thread ensures the blade assembly does not unscrew during normal blender use.

Firstly disassemble the blender blade assembly. Place a folded tea towel over the blades and hold the blades firmly. If you do not use a tea towel you may cut yourself.

Grip the wing nut with your other hand and unscrew it CLOCKWISE.
Remove the wing nut. You can now remove the blade from the plastic base.

Put the blade assembly in the new jug and offer up the plastic base from under the jug so that the blade shaft protudes enough for you to install the wing nut.

Screw the wing nut ANTI-CLOCKWISE to secure the blades to the plastic base.

Do not over tighten the wing nut; you may have to replace your jug again at some point.

Exact same problem.  Turned out the threaded shaft that holds the blades was broken so tightening the nut on the top doesn't really help.  Just ordered a new blade assembly from www.smallappliance.com.  Mine was the Waring 007314W Blender Cutting Assembly but there is also an older one for earlier models.  Don't know if it will work yet (assume it will), but cheaper than buying a new blender.
