Clutch adjustment problem on CB500 K2

[Nashfly]

OK so an FB post couldn't throw any light on this issue (Julie seal was helpfull, thank you)

I took thr LH crankcase/sprocket cover off to replace the clutch cable - the clutch was working fine

Obviously a strip, clean & re-grease was required, but I noticed that the clutch adjustment clamp was missing and the clutch adjustor wouldn't move

I eventually removed the adjuster, with a fair bit of force, but it is obviously too big for the hole in the case - the hole is 26mm diameter and the adjuster is 27

Can anyone any light on this and suggest a fix

Also, does anyone have a spare adjuster clamp?

Thanks in advance for any assistance

As far as i know all the 500 are the same but they do corrode, only place i ever saw them was silver but not cheap. There is a sevice bulletin about clutch adjusters in alladins cave

Is yours a CB500K2-A or the years later CB500K2 GENERAL EXPORT? You may want to consult the latter's parts list* to establish what you have now and what you would like to have. The K2 GENERAL EXPORT came with a modified clutch adjuster. I never had a problem with it. The former adjuster 22841-266-000 was on 82 other Honda models, the 22841-323-000 only on the CB500K2 GENERAL EXPORT.

Has your sprocket cover a hole for the slotted adjuster so it sits pretty much flush with the casing when bolted in place?

Did wonder if the larger diameter part you have has the lock bolt mechanism  missing as it would not fit being for a different model. The CB175 has a similar mechanism 22841-216-030 my 500 has 22841-266-000.

That's the kind of part Ash or Ken might have in their stash.

Thanks for the replies - much appreciated

I've now sourced the adjuster clamp

The model is an import from USA

Just need to sort the adaptor

How will you be able to fit a 27 mm adjuster into a 26 mm hole as iirc the adjuster fits from the inside with the flange preventing it from passing through the casing hole?

Or have you sourced the standard adjuster 22841-266-000?

Thanks to everyone for their input

The adjuster clamp bolt had a filed down nut in place of the clamp (there was another nut underneath the ball bearing!)

I have used emery cloth to reduce the size of the adjuster - it fits!

Waiting for delivery of the adjuster clamp and a new ball bearing, plenty of grease and everything will be ok

I knew when I bought the bike that a bodger had been working on it, to give you an idea of his incompetence, below is a picture of one (of two) bolts that were replacing the long stud on the rear bottom engine mount (the nuts were filed down to fit in the channel the rod should pass through)

I'm one step closer to completing my RC181 replica - thanks to all on here (I'm sure they'll be more questions to come)
