Pop off the E clip (circlip) that holds the sprocket and retaining washer on, remove these components, grease the bearing with heavy HT grease or similar, push the sprocket back on making sure the oiler arm lines up with the small cut out in the outer rim of the drum, and replace the washer and e clip.

 

Make sure the e clip is located correctly and off you go.

 

It is worth pushing lightly on the opposite sides of the clutch in turn to gauge how worn the bearing is. If the play is excessive, replace the bearing and if still there, replace the drum.

 

The grease tends to get chucked out PDQ, not much you can do about it!

 

On 261s with excessive play on the drum, check the oiler arm hasn't been broken or worn away - it should mesh with the clutch drum notch.

 

If it is damaged, order a new one and is available with or without the nylon pinion.

We've 2 x 261s which recently have started to cut out when chain brake applied.

Classic case if clutch springs going so I understand OR is it a worn bearing causing the clutch to move and snatch the clutch/brake drum?

Check the clutch drum for "wobble" (with chain break released). If it wobbles you need to change the bearing and possibly the drum.

 

Take off the drum first, and check for a piece of string or similar around the crank-shaft near the bearing. Same symptoms. And while you are at it, give it a good clean – a LOT of crud (scientific term) can accumulate behind the drum.

 

Broken or weak clutch springs is another likely cause, as you point out.

Staying away from that model in the first place is of course a much better idea - but each to their own....:biggrin:
