Hi there,

I have just added a third friction plate and indeed my clutch pushrod is too short.

Do I just cut it in half, put the first half back, add a 1/4'' bearing and then the final half of the pushrod?

Am I right in thinking that these pushrod parts and bearing will be contained within a channel in the mainshaft?

Thanks Dave.

Yes that is correct, it is best to use a 1/4 roller, not a ball, make sure the ends are square and flat, before forming small chamfer and ideally, re harden.
Grease the rod and roller on assembly, all helps to make clutch lighter to operate.

And if it's still too short, put two rollers in!

Very helpful and detailed clutch information.   after the great clutch info I really enjoyed Ian's reply to Owen's statement that neither of his C bikes
chaincase leaked.    I would agree 100% with Ian.   I started riding motorcycles in 1943 and in the 40's I had an Indian and then a Harley Davidson and
I bought my first BSA, a new A10 in 1951.   One of my favorite stories about 1940's & 50's pre unit motorcycles of any make is that if you parked one for
any length of time and when you started  to leave look under the bike.   If you didn't have a small puddle of oil you better check your oil because you probably
didn't have any.     (for the record I didn't understand Owens final reply about the Tena Lad's)

I've looked back, John, and I didn't understand Tena either so thought it was probably a typo or a private joke. And I live here!

Some times I'm so subtle it astounds me.

It was for the comment 'if you have no drip then you have no oil'. However for an alternative look on the subject may I suggest you try Tena Men for those annoying little or large drips!!!!
