At first glance I thought this was badly worn but looking at the part picture on DS it looks like its how they are designed!
When I reassemble it is there any point in packing it with grease or will the oil in the clutch somehow provide lubrication?

This is normal. As long as the balls in the cage are perfectly round, no rust or flat spots just a smear of grease on the balls is needed. Also remember to change the o'ring ;)
-
The balls are in pretty poor condition not sure what size they are perhaps DS sells them.

They have not been available for years. PM Julie as i will have some somewhere.

I've measured them up they are 10 mm bearings - my brother should have some that size - if not I will contact NJ. Thanks
Not sure about the O ring its a small critter do you know the size by any chance?

The ball bearings are 10.25mm, so 10mm ones will fall out of the little baskets. I think the 10.25 size is specifically licenced to Honda, as I have searched worldwide for replacements and can't find any. Even in imperial, there is no exact equivalent.

When I measured mine they were 10.12 mm and are more like a golf ball texture. I need 3 that are much better not sure what to do.

Steve has got some.

13/32" balls are available (0.07mm too big). Does anybody know if these would do. https://simplybearings.co.uk/shop/product_info.php?products_id=38926&vat_inc=true
-
I've sourced one from NJ thanks guys. I think 13/32 is too big for the cage and the bit they sit in. The size is closest to 0.4 inch.
-
10.25mm = 0.40354”
13/32” = 0.40625”
Would a difference of 0.00271” make such a difference?
If they measure 10.12, that’s 0.39842” so a difference of 0.00783; still not big, but too big?
I’m interested to hear wha they thoughts are, because I’d be tempted to say, “close enough”, certainly in the first case.
-
I suspect that 0.00271" would stop the balls moving within the cage - or at the very least bind. I'm happy to fit the ones from NJ they will be good for many years.

It doesn't work as i have tried it many years ago ;)
