Fitting the clutch - a simpler way.
We read many calls for help on this subject. I originally experienced the usual problems of starting the nut etc and developed my own method which has served me well. No special tools are required other than a ¾” ring spanner (if UNF shaft) and an oily rag, both I suspect in your tool bag if you’ve got this far.
Have the clutch and primary drive assembled. I don’t bother with elastic bands, just hold it. Put the bike in 4th, top, gear and oil the splines. Slide the primary drive into the splines and hold the clutch together by pressing inwards. I use only a single shim under the sleeve gear nut, but it’s up to you. Oil the shim and put the nut in position.
Now the trick bit.
Slide the final drive sprocket on backwards and hold in place with the heavy washer over the cross drive and the Main shaft nut. Tighten this GENTLY until the sleeve nut just contacts the thread. The sprocket keeps the nut square. Sprag the primary drive and turn the sprocket clockwise until the thread starts, using your oily rag on the teeth. The sprocket will grip the nut and engage it on the sleeve gear. You may need to take up the slack a little as it starts, but go carefully. Once started take off the sprocket and tighten, as normal, with your peg spanner of choice, checking and correcting cockled springs as necessary. Fit the locking tab and drift the nut until the next hole lines up and job done.
