CT rubber seal falling out

[bobtskutter]

Hello FOG,
I have a CT36M.  Every time I remove the motor head from the tub unit the rubber seal in the motor head falls out.  It's the rubber gasket that seals the joint between the motor head and the tub.  I have to manually reseat the seal and carefully lower the motor onto the tub to make sure the seal doesn't dislodge again.

Does anyone else have the same problem?

Thanks
Bob

Not me, mate.

But if it did happen repeatedly, I'd take off the seal, run a thin bead of clear silicone along the bottom edge of your motor housing, and reinstall it so that the sealant acts like a flexible adhesive. It might even be easier to run the sealant bead on the actual rubber seal itself if it has a 'U'  shaped profile where it attaches to the housing. Less messy.

I'd suggest a neutral, non-solvent-based silicone which won't attack the rubber. The best one to use is this fella;

Hope you get fixed up. All the best.

I doubt the silicone would hold on the rubber but worth a try.

How old is that seal? Maybe just time to replace it?

I doubt the silicone would hold on the rubber but worth a try.

The non-solvented acrylic ones (785N) hold on very well - the acetic acid-based solvented ones (785+) don't. And speaking on behalf of Bob - this CT is a fairly new purchase.

[member=75780]woodbutcherbower[/member] thanks for the suggestion, I thought gluing it in place might be the answer.  I'm surprising it's not secured in place.  Thanks for the reference on the silicone, and the explanation.  Much appreciated.

(the machine was bought new less than 6months ago).

Regards
Bob

I have no reason for recommending this stuff, except that it appears to be used for this exact application.

It makes me think that it got mis-seated once, something got cracked, cut, or dislodged, and now it won't hold on its own any longer.

If I can physically get to it, I may pop the motor off of my CT26 tonight (it's the same power head, after all), and see if there's a 'catch' that's supposed to hold the gasket on, or if it's just a friction fit.  Someone else whose CT isn't buried behind piles of backed up work may be able to do the same, sooner.

 

[bobtskutter]

I took the whole seal out.  It's a single piece of rubber and is held in by friction.  I cleaned the parts in contact with the rubber seal by wiping off any dust with my finger and a cloth (no solvent) and doing the same on the seal.  I put the seal back in and it appears to be holding OK.

Thank you all.

Regards
Bob

Sometimes clean, smooth surfaces behave counter-intuitively it seems to me. 

In my mind, if both surfaces are perfectly clean, the gasket would simply flop off.

But I saw a demonstration where there were two large and heavy blocks of steel with finely machined surfaces.  Neither block was magnetic. 

And yet, after the demonstrator cleaned both machined surfaces and lifted one atop the other, they behaved like a giant suction cup.  You could slide the blocks around, but if you tried to lift the top block, the bottom one would be lifted to.  And those blocks weighed around 50 pounds each.  No Grabbo required.

It might just be luck at the moment, but it seems to be staying in there.

Bob

Addressing the title, I haven't contributed to this web site for the last several days because it was so slow...fast forward...it's still slow. WTF...is everyone just sitting on their thumbs?

Suggestion: maybe some of the resources that are used to support Festool Live could also be used to fix the onerous issues of FOG? My God folks...this website slowness issue has been around for the last week or more.

I'd love to add some content but this lack of web-site speed just makes the idea untenable...think self flagellation.

I suspect that the lagging site might be sporadic and not affecting all.  I am not experiencing any issues.  On 9/30 I noticed very early in the morning that the site was running slow.  I let Festool know and after Scot did some work on it the issues went away for me.  Perhaps logging out and clearing all caches might help/be worth a try?

It has been slow for me in the mornings, but later on it speeds up.

Seems totally random to me. Sometimes lightening fast transitions to another post and sometimes 15 seconds or longer. Seems to be very fast, kinda fast, or very slow. When very slow I just go to another website and return to the finally loaded FOG page later.

I too, have little patience with slow or balky websites, and I abandon FOG when it is slow.
