Bearing replacement - Jack Lalanne Health Master 100 8-Speed Blender

Probably the bearings in the blade assembly are wrecked, replace the blade assembly with a new genuine part. Someone here has fitted aftermarket bearings but I do not know how much gear they required to do the job. Search onsite for solutions may reveal more

If it is not the HUGE blade retaining ring under the beaker a bit loose then you will be buying new parts to repair it. The only other possibilities are beaker cracked and leaking (new beaker) or bearings & seals worn (new blade & bearing assembly)

The problem was the seal was worn, allowing liquid to seep past into the top blade shaft bearing washing out the grease and ruining the bearing. The "noise" you heard was the bearing running without any lubrication. Both bearings and the seal needed to be replaced but I have not found a source for purchasing these. Vita-Mix Company does not sell parts, they sell units (outrageously priced units)!

Seal under blade Assembly, on shaft leaks, allows liquid to enter bearing, which then fails, creates heat and overheats rubber, thus the smell. Bearing and seal must be replaced.

Had this happen twice before. The bearings in the blade area are going. We figured that in our dishwasher the heated water pools on the top by the bearings and as it cools water is brought in contact with the bearings and they rust. We have used penetrating oil to put a pool of oil around the bearing shaft and store it like that. Still noisy but cheaper than buying the replacement. Hand wash the blender to avoid this happening to your new one if and when you replace it.

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.
