Ryobi random orbit sande - squealing?

[Ian_Edwards]

I was doggedly sand away on the boat today using a 125mm Ryobi random orbital sander today, when I started to hear a squealing noise as I moved the sander around.
It sounded like metal rubbing on metal, not all the time but as I changed the pressure on the sander.
I'm using 80 grit, open mesh sanding disks and I have a Henry Hover connected to the sander, which collects most of the dust.
I'm so using a soft foam interface pad, about 10mm thick.
It almost sounded like I need to oil or grease something.
Has anyone come across this before, can I lubricate something, or i just order a new one?

Technically it may be possible to diy repair it, probably it’s just full of dust. I suppose you have nothing to lose. Open it up and see. If you can’t fix it, sling it.

Ryobi are about as cheap as you can buy so don't expect too much.
However they can (sometimes) be repaired.
Remove the base and check the bottom bearing.
I will probably be packed with dust.
Remove and take it to a bearing store for a 2 pound fix.

They are fairly easy to repair. It's likely to be the bearing on the pad. I removed mine and washed in a solvent, parafin or petrol as a short term fix. A new bearing was easy to source on eBay.

The sander failed this morning, it no longer has the orbit function, the pad spins at high speed and the extraction function seems to have stopped working.

I've taken the pad off, and I can see the bearing, it's obvious sized solid, and the fastening in the centre is also solid.
I've tried the correct size torx key and jamed the shaft. But I applied enough force to flex the torx key (think a typical allen key).
I've applied some "plus gas" and retired for some lunch.
Any tips on how to remove the fastening?
I've ordered a new sander, but that 2 to 5 days delivery, and I need to get on with sanding.

Is it a lefty tighty thread by any chance?

Not likely, if it turns right, like most sanders/grinders. Right hand self-tightens. Only if it spins left hand (looking down).

It does sound like it’s self tightened to a remarkable degree.

Plus Gas and an 1hr for lunch, eased it enough to get undone, using a 1/4" ratchet. It obviously had thread lock, or similar, it was tight all the way as I unscrewed it.
The Plus Gas eased the bearing, but didn't free it.
The next task is to source a new bearing. I don't know much about that.
Can anyone tell me what to order from this photo?


I think it's marked 6002-2RS, 1601, GXSH or perhaps CXSH.
Do I need the ID and OD of the bearing as well?

Brilliant, I'll double check the size and order tomorrow.
