Clutch cable adjustmentioned help?!?

[garynortheast]

As has been said by a few people here, it's a combination of worn worm drive and poor adjustment of the actuator screw.

Okay I've looked at the part number that ophic kindly posted on page one called "clutch screw assy" is that the whole bit that is attached by the two 10mm nuts? If the screw is damaged what happens to it. Does it wear away inside so it isn't as long when you go to adjust? I will buy the bit for 46 quid but just wanted to understand what happens to the screw assembly to make it malfunction.

Whereabouts in the country are you tojo82?

In gosport near portsmouth. I'm constantly reading to try and get a good understanding of the bike. I've done a few maintenance bits using the Haynes manual but I improve by understanding instead of just doing. Is it item 18 on this picture that "is made of cheese" from what I can see I have all my bearings in the worm so it must be this part that's shot?

There are lots of little ball bearings in a spiral retaining cage. The cage wears, the ball bearings slop about in the cage and you end up with a lot of unproductive movement of the actuating arm before it moves the clutch rod.

The bearings sit inside part 17.

Ah I see. So how does that create slack in the clutch cable? Thabks everyone btw for educating me

You are having to take all the unproductive movement out of the assembly by adjusting the clutch cable. The poorly adjusted screw and locknut and consequently poorly positioned actuating arm considerably worsen the problem.

Also with regards to the arm position, think about the effective range of leverage. Much more effort at the lever will be required with the arm in the position shown in your picture than would be needed if the arm was in the correct position.

Okay thank you then. I will purchase a new one this week. I'm assuming if I buy item 17 for 46 quid that's the whole unit. Thanks eveyone

What's the point of buying a new actuator if you haven't adjusted the current one correctly?

I have adjusted it according to the clutch mantra
