Hi All

  The inner in the new clutch cable for my C15 is too long. Could someone please point me in the direction of a crimping kit inc the tool, so that I can shorten it? 

  I have been hunting online but I keep finding crimps for pedal bikes. 

     BR,  Ian

could you use an electrical "choc strip" , this has 2 grub screws to shorten the inner cable , place this at the gearbox end.
otherwise, can you create a shortener(by lengthening the outer) by a short bolt - cut off the head if needed - put 2 hacksaw blades in your saw and cut a slot along the length and put this at the lever end

something like this maybe ??

To be honest I just want the ball shaped lead crimp to put on the end of the cable, and the crimp tool to go with it. 

 The adapter is a good idea, but I am not sure if there is sufficient space between the housing and the chain.  Also a bit annoying to have to do these sorts of things when fitting a brand new brake cable.

What do you want a crimping tool for?

rhyatt

Agreed , there's not much room at the outer cover end to do much modification.
Before you modify anything though , have you got the little ball bearing between the clutch arm and the pushrod end at the outer cover end and have you done the adjustment of the clutch cover screw and locknut and finally the lever end adjuster

Barnsey

Ahhh!.  No I don't have a ball bearing in that joint.  Any idea what size it needs? 

Barnsey

It looks like a 5mm ball bearing should fit (0.2")  I ordered a set from Amazon.

1/8" diameter springs to mind
Part 40-3071

Barnsey

If this is correct, 5/37" ( https://www.bsaunitsingles.com/item.wws?cpubcode=BSA&sku=40-3071 ), which is about 3.4mm.  I am guessing that 3.5 mm will be fine as it looks quite a loose fit. 
 

rhyatt

That indicates a 5/32" which is a shade larger that 1/8".

For the purposes of this cable length verification , anything that fits will do.

Ideally , whilst that outer cover is off , adjust the clutch cover end screw and locknut to give you a mechanically correct relationship between the cable and actuating arm (90 degrees max when operated)

Barnsey

The correct bearing is 11p  from Draganfly, with the VAT .  Hmmmmm Can I stretch to that?

rhyatt

Check the pushrod is the right length as well.
I feel it's 9 " and 1 end is square and the other end slight taper
And both ends hardened obviously

Wilco, I'll do that in the morning.  Thanks :)
