Clutch retaining nut tension

I haven't seen torque figures published. For both I clean the threads with electrical switch cleaner and then use loctite. I wind them up good and tight with a socket or ring spanner as appropriate and then give the spanner or bar a few modest wallops with a medium hammer just to make sure. Not very scientific but works for me!

The Haynes Manual gives the following:-

Clutch Nut - 70 ft lbs

Crankshaft Nut - 75 ft lbs

These figures have always worked for me. The camshaft nut is the same size/thread as the clutch. Gearbox and axle nuts must have similar torque firgures.

The most difficult nut to get right is the gearbox sprocket nut. This is set at 80 ft lbs on a Left hand Thread. I have a box spanner to tighten it but no way of connecting a torque wrench. So same as Gordon... I just use a Birmingham Screwdriver!!!

Hi,

Can anybody tell me what torque should be used on the clutch retaining nut as well as the shouldered nut that retains the rotor and front engine sprocket.

Thanks in advance and Merry Christmas.

Andy,are you talking about a Commando or a Dominator? Cos the

Commando clutch retaining arrangement is different-it tightens up against a circlip,which will start to shear at the stated torque of 70ft/lbs. Norvil states 35-40 ft /lbs,and it's worth renewing the circlip first.

for tightening the clutch center nut you need a clutch holding tool for the center boss . I made my own out of 1/4 plate steel and painted blue so you can easy see it . I paint my spanner too different colour so I know what there for. you can do this with electrical tape it comes in all colours just some you know what spanner is for what job on your bike. it just make life that bit easier .some like to set them tools out on a big white board and paint round them so them know its gone. and needs putting back in its place. but this to me just makes it easy of the thief . I put all my tools in my steel box and lock them up , and you can make most special tools too just for your needs. happy new year
