Hi all,
I'm trying to fit the rear wheel as per the diagrams on cmsnl, it looks like I'm missing some spacers or something. I've already added a spacer on the left, and two on the right just to give me enough thread on the axle bolt to tighten things down, and there's still space in each chain adjuster. This can't be right - where have I screwed this up?

Can't understand why so many washers on the spindle ? Can not see from the picture but are they the right adjusters ?

I put the washers on so that I wouldn't run out of thread on the axle, seems like it's too long?

Was this wheel fitted to the bike when you got it, or was it loose in a box of bits? Somethimg looks amiss on the sprocket side of the wheel. Did you replace the wheel bearings? if so, are you sure you put the spacer between the bearings back? (saw that on my CB175 when I bought it years ago)
-
Bit new at this, is this on a 500? If so the swinging arm looks wrong from the exploded diagrams that I have.
Probably talking coblers.

looking at the picks,all the spacers seem in place,the only difference to mine,is the nut is on the drive side,
may be the swing arm is wrong,how does the chain line up?when the sprocket is close to the l/h side,is the chain aligned??
-
Don't know how to post a picture, but that definitely looks like the wrong swinging arm. The slots for the axle should have an open end with a retaining block bolted in to close the slot, it should also be thicker which would explain the gaps that you have.
-
I cant remember if yours is a 500 or 550 Mr T. I have just looked at the swing arm on my 550 K3 and the slots for the spindle are closed in on mine.

The swing arm is 550F1 or F2 ;)

Perhaps a jumble of 500/550 bits?

And your 400 had a wobbly rear end ;D ;D ;D

Just concentrate on Mr T's back end thank you Trigger 😃😃😃😃😃😃😃

That top pick of the drive side on your bike seems to show a spacer I don't have.

The brake plate, spacers and collars are different on a 500 with removable ends in the swing arm to a 550 with the closed end swing arm. Can't remember exactly what and where but what you need to do is get the wheels in line the add or make spacers to fit the gaps, may even need a 550 spindle
If you have the time check which part numbers are different 500 to 550F on the diagram and that will tell you which bits are different
-
I'll check it out Bryan. The swingarm is definitely 550, but looks like the spacers may be the issue. Will get it sorted in the end!
-
Don't forget the brake plate is different as well, they will swap one way round but not the other as there is a difference on the outer diameter as well as the "Hump" the spindle goes through

That may be part of it then. The rear wheel and brake plate I used was bought off eBay and I don't know it's exact provenance. Is there an easy way to tell the difference?

If there is a missmatch it will probably be in the form of the wheel not turning once the spindle is done up tight. I wouldn't worry about miss matched components too much at this stage, just get everything lined up, eg chain run streight, and wheels in line front and rear. I think about 50% of the bikes I own(ed), mostly the cb500 and 550s had some sort of gap issue on the rear wheel and swing arm but beyond bunging in the odd washer to keep it all alighned I have never let it bother me, often the swing arm flexes in a few mm when I tighten the rear spindle, as long as it ends up in line the bike handles fine, passes mot's etc, if fussed about the washers being unsightly, measure the spacers plus washers, get someone with a lathe to turn up a spacer the right length. Job done.

I read this thread with interest. On my CB500 I discovered there's some play that causes the part (flange final drive?) on which the rearsprocket sits to move a mm or so out of the hub when rotated and because it is irregular it causes a not nice running drivechain. I haven't figured out what exactly is the origin. I seem to remember having seen that the collar rear wheel side was irregularly worn (but... because of what???) and having seen some iron dust there. Could that collar somehow be the culprit. Is there a possibility to help this with a washer somewhere?

I wonder if Matthewmosse recognises my problem. Dealers are not much help: one said there should be a third bearing somewhere and another I talked to on the phone said I needed a new flange and they're bloody expensive. Help is appreciated.

You can also get wear and movement from some after market sprockets ;)
-
Deltarider, try removing the rear bearing retainer on your wheel, the sprocket carrier is meant to have some grease on the surface where it meets the wheel boss, the reason for this is because as the dampers which cushion the sprocket carriers are crushed under acceleration etc the carrier itself moves very slightly forward, if there is no lubricant between the 2 surfaces you get wear, this could be where the metal dust is coming from, if there is enough wear the carrier will start to fluctuate and the sprocket will start to oscillate, meaning more chain wear and noise.
This could well be the case. A long time ago I renewed the rearwheel bearings and I can't remember... that bearing retainer is supposed to fasten that flange to the hub, right? There's also a possibility I haven't screwed that retainer in all the way. Anyway, I suppose I have to look for another flange.
I presume you've still got the sprocket dish fitted?
Yes, does that play a role here?
-
If the bearing retainer isn't tight then you will get sprocket float as the entire cush drive is moving around, best get that sorted ASAP as the chain may come off if it gets to a certain point.
Thanks again. So the retainer needs to lie flush (is that the word?)
-
Oddjob, you were right about the sprocketcarrier and as you can see I brought the problem to the international SOHC-forum: http://forums.sohc4.net/index.php/topic,150358.msg1716136.html#msg1716136
At the moment the key question is: why are these 4 crossradial grooves in there? The reason I ask is this: if they're ment as wear indicators, it might help me find a good secondhand one.
-
Not a trace of wear on the steel boss of the hub. I have no idea what steel that inner part of the sprocket carrier is made of.
