I have an Alex Duetto II with a rusted top motor bearing. Looking for a source for this bearing for replacement. Motor type is RPM SPA C005540.

Any good electrical motor repair/rebuilding shop should be able to assist.

I am guessing that you are looking for the bearing on the pump motor as I can't think of any other motor in an espresso machine.

It is likely that as was said, a motor shop might be able to help you. Many motors though are designed as "throw aways" I am not saying that yours is one of those but if it turns out to be one or that the bearing is nearly the same cost as the whole motor, I would not be supprised.

No idea if you got that fixed or not, but a good quality 6202 bearing with metal covers on it should work. RPM motors split apart pretty easy. I can replace the bearings in one in about 45 minutes using a vise and a few hand tools. Bearings are about $12.00 each, just a bit cheaper than the $200 plus you'll lay out for a new motor.
Ciao!

Hi Chris

   Can you mention what brand of 6202 bearing that you would recommend. Also what is the letter designation following 6202? Do you stock these?

   Thank you in advance for your help, Al

Before you buy a part, there are dimensions to take into account, not every motor uses the same parts. There is the diameter of the motor shaft, the diameter of the housing in the motor and the thickness of the bearing it's self.

Just saying.

I have a Reneka Techno V2. The pump and motor started to make quite a bit of noise. I replaced the pump, and although quieter, the motor is still noisy. A pic of the pump is attached below; any update on how to choose and replace the bearing, or where to source a motor?

Thanks!

The motor will almost certainly be fine and just need one or two bearings. It will be one of two types: the standard roller bearing with metal shields or the staked-in spherical bearing. Once you separate the motor this should be obvious. If you look on the outer race or the metal shield, there will be a number like 6202-ZZ on it. That's the part number. The staked-in spherical bearing will be an adventure as it is pressed in at the factory and the motor casting is squeezed in place around it by a big press. In that case you are better off replacing the motor. Most of the online dealers who carry parts should have it; it's similar to the motor used on the GS/3.

Some machines are just naturally noisy, my ECM is FAMOUS for being loud even though it is a rotary pump, just as loud as a vibe pump. It is the way that the motor/pump is mounted in the machine, the sheet metal acts like a speaker cone to the vibration of the motor/pump.

Appreciate the replies. Re normal noise level, I've had the machine for over 10 years and it's been quite muted until the last couple of months. When I pulled the pump to replace it, there was some crud in the motor housing, which may have been aluminum or something leeching out?  I'll pull the motor this weekend and post the results.
