Evening all,
I have some concern over the rear wheel bearings in my 1400.
I'm currently putting her back together and noticed that the bearing in the sprocket carrier needed replacing so thought I'd have a look at the bearings in the rear wheel, didn't think there would be an issue as the previous owner had the wheels powder coated and replaced the bearings. However the bearings aren't tight in the hub and you can withdraw the bearings most of the way out by hand with just the last few mm needing the use of a drift. The bearings appear to be the right size 52 o/d, 28 I/d, I've measured the seating face for the bearing and that appears to measure between 51.7mm and 52mm.
Now I asked for some ideas on a Facebook 1400 group last night and was advised that 1 reason for the problem could be when the wheels where powder coated they might not have been masked up properly and the media blasting might have caused the issue. Was advised loctite bearing retainer to secure the bearings or having wheel machined and a sleeve put in to bring them to the right diameter.
Have people had any experiences with either of these methods or should I go down the route of another wheel, I haven't looked at the front wheel yet 😂
Craig
No experience with this. Wouldn't do the loctite hack for sure. Wouldn't do the machining/sleeve option either as you will then have steel against steel. Might cause you grief replacing the bearing.
And d... the previous owner as he (must) knew what s... he sold you.
Hello Craigl,
I would have no problems with useing Bearing fit Loctite , been using it on all aspects of engineering for 40 odd years, Yes try it , if a problem ( I dont think you will have any ) then look at other options....
Phill
That is exactly what bearing fit is for I'd have said.
Ooops, didn't know that loctite had such a diversity of products, Just read loctite and thought it was a hack :facepalm:
Yeah they do a lot of stuff, it's important to pick the right one for the right job.
Thank you all 👍
Bearing fit it is then, Phill/Holli what would you suggest as there seems to be many that fit the bill 260/638/640/641 - plenty to choose from 😂😂
Craig
old mechanic here. have a look at 680 loctite. should help
Thank you grog, was reading some of the specs of the various options and they all seem to do a similar job but with different levels of adhesive depending on the intended purpose with regards servicing etc.

MAYBEE crap bearings,as i said last month,what milage??30000?by any chance :rolleyes:

I don't think so, if you read the post, the bearings are the right size, and the issue was most likely caused in the powder coating process.
Hi
thought it was just me. Wheels powder coated but no evidence of improper masking. New bearings where fitted and hammered in using a drift. Seemed totally normal. While later removed wheel and found both wheel bearings would slide in and out of the wheel about 5mm. Hadn't noticed any handling issues. Glued them back in with some bearing retainer from an autostore. Would have nipped into work and used a bit of 638 loctite but it was a bank hol weekend. All seems ok. Guess the proof will be when the wheels out next. Don't under estimate industrial adhesives. We use a type of superglue that contains tiny strands of kevlar/carbon and the only way to get them apart is to chisel one of the parts off. the metal fails before the bond
If I ever get my wheels powder-coated, I will leave the bearings in. That should protect from "professional" sandblasters. Then put new bearings in when I get them back :smoke:

Sounds very similar to my situation. The bearing seats look ok, well ok to my untrained eye 😂 But the bearings slide nearly all the way out with only needing a little assistance to get them fully out.
I haven't taken care of the situation yet as I'm still currently rebuilding my bike and I'm tempted to have the wheels powder coated silver to match the bike and I don't fancy having to replace the bearings again come the winter.
Craig
another bike i had, wheels powdercoated, couldnt get bearings in. agree with leaving old set in there. replace when job /painting done. best idea.
