Topic: CB500 rear bearing retainer

[hudstr]

Ok, the time has come where I need to find a fix for my problem, no more putting it off. I have 2 retainers, a new one from 4into1 or david silver spares, don't remember where I bought it, and my old one. The problem I have is the new one will go in maybe 1 or 2 threads, then resist and won't go anymore. The old retainer goes in just fine, until I hit the mangled threads at the end (see picture). I as well as someone else have measured them and have found the new retainer is bigger from thread to thread. I believe I found it at least 10 thousandths bigger and the other person found it 12 thousandths bigger.

Reading some other forum posts, people just say clean up the threads with a tap, but I don't know if it will be possible being so close to the lip of the retainer. I'd much rather use blue or red loctite than use a punch to hold the retainer in, would blue loctite suffice or should I go with red?

Any ideas are welcome.


New retainer

Old retainer

A small chisel actually straightened out the threads better than expected. The tap I have tapers at the end so it is too long to get the affected threads. I'll have to buy one which will fit. I would take a picture of the threads but my phones' camera lense has been scratched for a while now so it doesn't focus properly. I just ordered a new one of those so maybe my pictures won't be blurry anymore.

it shouldn't be a tapered thread?youll be hard pressed finding a tap that size let alone a left hand thread,use a thread file.

Mine did the same thing. Take this as a suggestion that worked, but use good judgement. The threads in my hub were all good visibly, and the retainer went on easily about 3/4 of the way smoothly. I threaded the retainer up to the sticking point, then worked it back and forth progressively till it was all the way on.
I used penetrating oil, and went little bits at a time, not using too much force to persuade things, and regularly backed the retainer out completely and started again. The retainer cleaned itself and the hub. It took a while, but all turned out well, as I can thread it in by hand.
It threads on smooth and seems to bottom out when tightened, so I called it good. Hasn't caused any problems so far. I dunno, Maybe I just got away lucky, results may vary.

Any tap with the same thread pitch should work. If the search were working there was a fine post on this. It is sort of a carving motion easing the bent over material back into shape. The other procedure of working the retainer in and out would bring everything back into proper shape. While anti seize is a great lube, it is messy and does not allow you to see what you are doing very well, oil would be easier to work with. Since the retainer is really well captured blue loctite would be all you need.

that rear thread is steel on steel.

Oil is not a great "thread lubricant". AntiSieze would be much better since its aluminum-aluminum and will prevent the threads from galling.

the rears are #$%*ing steel!the fronts are alloy,the male rear retaining screw is steel full stop!

[dave500]

they are all steel on rears.

[dave500]

I do apologise cal,the hub is alloy however the retainer ring is steel,please accept my most humble apologies and hope others haven't been misled on this issue.

Just wanted to say, I took the advice in your post and it has worked perfectly, I had the same issue.

Thank you for posting,
