Has anyone ever used this? I put one of the Mito rear wheel bearings in and whilst it fits nicely, you can rotate the outer part of the bearing whilst it's seated in the wheel. Surely that ain't right? So I'm wondering if this Bearing Lock will hold it in place...

No one? Well I did some looking and apparently Loctite 660 does the trick. Surprised nobody here has never used any, perhaps I'm the crash test dummy  Alex |

Sorry, only just seen this
I had a billet hub like that. Hub was brand new as was the bearing but it had obviously not been made for an interference fit
Absolutely no play but if you turned it on its side and tapped the opposite end the bearing fell out
Smear of bearing lock on the bearing and the hub, slipped the bearing in and tightened a bolt through the middle till set

On a side note my TSS balanced crank has outer bearings like that. Just slip on to allow a little float

Cheers Steve, that's a weight off my mind for sure.

you can use a punch on the alloy land to raise the areas around where the bearing sits if you dont want to glue.

I've used the Granville brand red "bearing fit" stuff before, it worked great. Needs heating to at least 100 degrees C if you ever want to get the bearing out again though.

I've no real experience of using bearing lock before. Is it really that good that it will overcome the rotational force going through a wheel bearing ?  |

Well that's good to know I've never had a wheel bearing that isn't a tight interference fit, and it concerned me when the bearing dropped straight in and could be rotated in it's housing  |

It should work well enough; "thats what its for" etc.
It'll work until the bearing dies, it'll seize and cause you more grief and now youve a bit of a mess of glue to clean up as well.
Ive always felt its a bit of a bodge but it seems its pretty well accepted as a fix these days.
But is it a 'get you another mot fix' or the real deal... hmm...
(same with the punch version... its not a real fix, but gets you out of trouble)
Always remember... if you do a crank bearing... ONLY DO ONE CASE SIDE!

Loctite red I've used in the past. in severe cases you can centre punch the outer face to then give some interference for the bearing to work against when assembling. Don't go mad with a size 3 mallet mind!

You can get shim material if you can get a feeler gauge in.

I’ve not used it on a wheel bearing but have recently used loctite bearing fit on some head bearings where the frame had been sandblasted and they didn’t fit as tight as I thought they should.

Bearing lock does what it says, it locks the bearing in place
There are two types, standard and heat resistant and it’s stronger than high strength thread lock
It’s other uses are if you never ever get the bolt or stud out again, or p1ss off a wise guy, or keep an apprentice occupied for a day trying to extract said bolt or stud from its home
A gas axe will burn the glue off though, same as any other thread lock
I’ve used it on a tow ball bolt that kept rattling loose every few miles travelling up a very badly corrugated outback road towing a trailer
I put a bit of bearing retainer on it and it survived another 5000 miles, the hire car company couldn’t remove said nut with a 3/4 rattle gun, until they rang me for advice

Hi Alex as mentioned above a bearing retainer medium is good to to use in the correct circumstances and certain engineering designs need it. I use it a lot.
I would use it for your application as long as the bearing is not too loose.
Go to the loctite website as there are plenty to choose from and try to pick one which suits your application best.
I always consider the the clearance I have between the two parts as very important.
Off the top of my head I would say 648 is a good allround bearing retainer medium. Not sure but 638 could be a better choice for aluminium. Best check the Henkel website.

Just as long as it’s safe, that’s the main thing…
These old bikes often require corrective measures that are ‘marginally acceptable’ rather than preferred… but that’s when you put cost / absolute risk/ likely run-time in the ‘scales of prudence’ and conclude.
Personally if I rolled a wheel across the garage floor and a bearing fell out the side , I’d want to know exactly the root cause and the implications of, before I slapped it all back together…
