Hi all

It will be posted shortly.

Motor bearing kits have been around for years. though the bearings are just standard sizes and can be sourced easily.

An image of a third party bearing kit is attached. I had already bought SKF bearings for the motor, but the NSK bearings in the kit are very high quality as well. The top bearing isn't rusty - it's preservative. It's in a sealed bag under the shrink wrap.

As mentioned earlier, the main things I wanted were the threaded bearing retainer and screws.

Qualtex, that explains it. When I first started in the trade I had an account with Crum & Sons of Glasgow. They were Qualtex agents but they were hopeless, sending the wrong parts all the time. I soon abandoned them in favour of other suppliers, athough I probably still have an old Qualtex catalogue in the shed in UK. The armature kit used to include that same retaining plate and screws. Most armatures are not designed to have new front bearings, as the pulley is bigger than the front bearing inside diameter.

Hi fido

It's funny you should mention pulleys larger then the bearing inside diameter, as I pulled the motor off my Bosch washer (2007 vintage) this week to check the brush wear.

I wonder how the pulley is fitted. It must be either pressed on, or heated and pushed on for a shrink fit. Can these motors can be repaired at all, apart from the brushes?

Actually the rear bearing seems more liable to fail than the front so I have put new rear bearings in quite a few Hotpoint GEC motors over the years. Yes, I think the pulley is probably shrunk on before the armature is wound and you could probably not heat it enough to remove it without damaging the windings.
