Title: First time it's seen the road since 1976 and clutch makes catching noise
Post by: RichardL on 29.12. 2012 20:30

From JSF:

"I've got the front forks working a little better now (too much oil!) but the (newly fitted) clutch is making a 'catching' noise (which goes away when you pull in the lever)."


John,

Do you know if the bolts holding the sliding plate behind the clutch are of the short head type? Is your primary chain at the correct tension? Are the spring tension nuts double nutted or nylon restrained? (I don't really know if a nut that was loose or fallen off would make a noise or just massively jam or destroy everything).

So - we've got the Lyford clutch back off the bike again - there seems to be around an eigth of an inch play (perhaps a bit less) in the clutch basket! There's no play in the centre. Does this sound reasonable - feels a log if play to me but I've no idea how big a problem this us.
Any ideas much welcomed
John

After much googling it seems a little play is normal so it's back together - can't get it to go though as has got quite damp in the shed with condensation but it will be home in my warm garage soon - then the questions will really start! Thanks again all
John

The clutch will have slight play both my bikes have and do not cause noise or catching and have fine running of plates etc John

Hi there fella, I had a bit of play in the clutch basket and none on the centre like you. When I took the clutch basket off I found that the basket had been catching on the case a bit and some of the roller bearings in the back of the basket where of different size and length to the rest. After I got new roller bearings and re fitted the clutch there was a lot less play, still had a bit of play but nothing to write home about. All the best chicago
